[0179] This technical solution embodiment proposes a multi-legged bracket, which includes a support rod and at least three legs. The at least three legs support the support rod, which in turn supports the electrical component. At least one of the at least three legs is a telescopic leg.

[0180] The telescopic support leg includes a first support member and a second support member.

[0181] The second support member is provided with a second sliding groove.

[0182] The first support member is fitted into the second sliding groove, and the first support member is slidable relative to the second sliding groove to change the length of the telescopic support leg.

[0183] The second sliding groove has a third base surface, which is adapted to the outer wall of the first support member.

[0184] The first support member has a first extrusion protrusion, which makes extrusion contact with the third base surface so that when the telescopic support leg is in a supported state, the first support member can be positioned in the second support member.

[0185] During the sliding process of the first support member relative to the second support member, the third base surface can slide over the first extrusion protrusion.

[0186] This technical solution embodiment proposes a multi-legged bracket, which includes a support rod and at least three legs. The at least three legs support the support rod, which in turn supports the electrical component. At least one of the at least three legs is a telescopic leg.

[0187] The telescopic support leg includes a first support member and a second support member.

[0188] The second support member is provided with a second sliding groove.

[0189] The first support member is fitted into the second sliding groove, and the first support member is slidable relative to the second sliding groove to change the length of the telescopic support leg.

[0324] The technical solution will be further described in detail below with reference to the accompanying drawings.

[0325] This specific embodiment is merely an explanation of the technical solution and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any innovation, but such modifications are protected by patent law as long as they fall within the scope of the claims of this technical solution.

[0326] This technical solution embodiment proposes a multi-legged bracket, referring to... Figures 1-27 ,or Figures 27-48 ,or Figures 48-66 ,or Figures 70-96The multi-leg bracket includes a support rod 1 and at least three legs 2. The at least three legs 2 are used to support the support rod 1, and the support rod 1 is used to support the electrical main body 3. At least one of the at least three legs 2 is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The second support member 200 is provided with a first sliding groove 201. The first support member 100 is sleeved in the first sliding groove 201 and is slidable relative to the first sliding groove 201. The first support member 100 is in damped contact with the first sliding groove 201 so that when the telescopic leg 2a is in the supported state, the first support member 100 can be positioned on the second support member 200.

[0327] In the multi-leg bracket implementing this technical solution embodiment, one of the legs 2 is a telescopic leg 2a. When the multi-leg bracket is not in use, the first support member 100 can slide relative to the second support member 200, thereby shortening the length of the telescopic leg 2a and reducing the volume occupied by the multi-leg bracket. Furthermore, when using the multi-leg bracket, the length of the telescopic leg 2a is adjustable, allowing the multi-leg bracket to better adapt to uneven or inclined support surfaces.

[0328] For example, when the telescopic leg 2a is suspended relative to the support surface, the telescopic leg 2a can be adjusted to make it contact the support surface.

[0329] For example, a multi-legged support can be a tripod, quadruped, pentagonal, or hexapod, meaning the number of legs 2 on the multi-legged support can be 3, 4, 5, 6, etc.

[0330] For example, the electrical device 3 can be a fan, lamp, mobile phone, tablet, etc. For example, the fan or lamp is fixed or movably installed on the support rod 1, and the mobile phone or tablet can be held by a clamp 4, which is fixed or movably installed on the support rod 1.

[0331] For example, refer to Figure 27 This technical solution embodiment proposes a shooting bracket, including a shooting terminal 3 and a multi-leg bracket. The support rod 1 of the multi-leg bracket is used to support the shooting terminal 3, which can be a mobile phone, tablet, etc.

[0332] For example, at least one support leg 2 is fixedly installed on the support rod 1. For instance, at least one telescopic support leg 2a is fixedly installed on the support rod 1. For example, the first or second support member of the telescopic support leg 2a is fixedly installed on the support rod.

[0333] For example, at least three legs 2 are fixedly installed on the support rod 1, and at least three legs 2 can be opened radially relative to the support rod 1. For example, all legs 2 are telescopic legs 2a, at least three telescopic legs 2a are fixedly installed on the support rod 1, and at least three telescopic legs 2a can be opened radially relative to the support rod 1.

[0334] For example, the angle between at least one leg 2 and the support rod 1 is variable; specifically, at least one leg 2 is rotatable relative to the support rod 1; more specifically, at least one leg 2 is directly or indirectly rotatably connected to the support rod 1. For example, the angle between at least one telescopic leg 2a and the support rod 1 is variable; specifically, at least one telescopic leg 2a is rotatable relative to the support rod 1; more specifically, at least one telescopic leg 2a is directly or indirectly rotatably connected to the support rod 1, for example, the first or second support member of the telescopic leg 2a is directly or indirectly rotatably connected to the support rod.

[0335] For example, at least one leg 2 is retractable or extendable relative to the support rod 1, such as at least one telescopic leg 2a being retractable or extendable relative to the support rod 1.

[0336] For example, at least three legs 2 are retractable or extendable relative to the support rod 1. After the first support member 100 of the telescopic leg 2a is retracted into the second support member 200 of the telescopic leg 2a, at least three legs 2 can be retracted into the support rod 1. For example, at least three legs 2 are movably mounted on the support rod 1. When at least three legs 2 support the support rod 1, at least three legs 2 extend radially relative to the support rod 1. When the multi-leg bracket is not in use, at least three legs 2 can be folded together or retracted into the support rod 1. For example, after at least three legs 2 are retracted into the support rod 1 and the first support member 100 is retracted into the second support member 200, at least three legs 2 can form a first columnar structure. The first columnar structure can be a cylinder, an elliptical cylinder, a prism, or a rounded prism.

[0337] For example, at least three legs 2 are telescopic legs 2a. After the at least three legs 2 are housed in the support rod 1 and the first support member 100 is housed in the second support member 200, the at least three telescopic legs 2a can form a first columnar structure. For example, the cross-section of the second support member 200 is arc-shaped or fan-shaped. When the at least three telescopic legs 2a are retracted, the second support member 200 with the at least three telescopic legs 2a retracts to form a first columnar structure in the shape of a cylinder.

[0338] For example, the first columnar structure is a cylinder; the support rod is a telescopic rod with 7 or more sections, the telescopic rod being more than 1.4 meters long in the stretched state, and less than or equal to 32 centimeters long in the retracted state, and the diameter of the first columnar structure is less than or equal to 42 millimeters.

[0339] For example, at least three legs 2 can be of equal length, or at least two of the at least three legs 2 can be of equal length, or at least three legs 2 can be of unequal length between each pair of legs.

[0340] For example, at least three legs 2 can be opened at equal angles relative to the support rod 1, or at least two legs 2 can be opened at equal angles relative to the support rod 1, or any two legs 2 have different angles relative to the support rod 1.

[0341] For example, when the multi-legged bracket is in the supported state, the support rod 1 is perpendicular to the support surface, or the support rod 1 is inclined relative to the support surface.

[0342] For example, when the multi-legged support is in a supported state, the support rod 1 is along the vertical line, or the support rod 1 is inclined relative to the vertical line.

[0343] For example, at least one of the at least three legs 2 is a telescopic leg 2a, and the remaining legs 2 are fixed-length legs 2.

[0344] For example, at least three of the legs 2 are telescopic legs 2a. The advantage of this arrangement is that the length of the telescopic legs 2a can be adjusted when using the multi-leg bracket, thereby changing the support area of ​​the multi-leg bracket. For example, when the length of the support rod 1 is long or the weight of the electrical main body 3 is heavy, the length of the telescopic legs 2a can be adjusted to increase the support area of ​​the multi-leg bracket.

[0345] For example, at least three legs 2 are telescopic legs 2a, and after at least three telescopic legs 2a change their length, the angle between the support rod 1 and the support surface remains unchanged (for example, the support rod 1 remains perpendicular to the support surface, or remains inclined).

[0346] For example, at least three legs 2 are telescopic legs 2a, and after at least three legs 2 change their length, the angle between the support rod 1 and the vertical line remains unchanged (for example, the support rod 1 is always along the vertical line, or has an angle with the plumb line).

[0347] For example, the first support member 100 is sleeved on the second support member 200. The second support member 200 can completely wrap around the first support member 100, or the second support member 200 can partially wrap around the first support member 100.

[0348] For example, the first damping protrusion 110 is in damping contact with the second support member 200, the first damping protrusion 110 and the second support member 200 are in tight fit, and the first damping protrusion 110 and the second support member 200 have frictional force, so that the first support member 100 can be positioned on the second support member 200.

[0349] For example, the second support member 200 is provided with a first sliding groove 201, the first support member 100 is slidably sleeved in the first sliding groove 201, and the first damping protrusion 110 makes damping contact with the inner wall of the first sliding groove 201.

[0350] For example, the first sliding groove 201 has opposing first stretching surfaces 201a and second stretching surfaces 201b, which confine the first support 100 within the first sliding groove 201.

[0351] For example, the first support member 100 is fully, partially, or partially enclosed by the second support member 200.

[0352] In some implementations of this technical solution, refer to Figure 15 or refer to Figure 78 , Figure 81 The first sliding groove 201 is a columnar groove, and the first support member 100 is circumferentially fixed relative to the first sliding groove 201.

[0353] For example, the first sliding groove 201 has a "C"-shaped cross-section, and the first support member 100 has a "C"-shaped cross-section. The "C"-shaped portion of the first support member 100 mates with the first sliding groove 201. For example, the first sliding groove 201 can be a closed "C"-shaped groove or a "C"-shaped groove with an opening. The advantage of this arrangement is that it improves the structural strength of the telescopic support leg 2a.

[0354] For example, the cross-section of the first sliding groove 201 is semi-circular, elliptical, polygonal, etc., and correspondingly, the first support member 100 has a portion with a cross-section of semi-circular, elliptical, or polygonal (and this portion cooperates with the first sliding groove 201).

[0355] For example, for a cylindrical geometry, the line connecting the geometric centers of its cross-section is its axis, the direction along the axis is the axial direction of the cylindrical geometry, the direction along the geometric center of the cross-section and perpendicular to the axis is the radial direction of the cylindrical geometry, and the direction around its axis is the circumferential direction of the cylindrical geometry.

[0356] It is understandable that when the telescopic outrigger 2a is in the supported state, the first support member 100 can be positioned on the second support member 200, which means that when the telescopic outrigger 2a is in the supported state, the first support member 100 can be held on the second support member 200.

[0357] Understandably, when the first support member 100 is housed within the second support member 200, the damped contact between the first support member 100 and the second support member 200 allows the first support member 100 to be positioned relative to the second support member 200 (i.e., the first support member 100 remains in a housed state relative to the second support member 200).

[0358] In other examples, the first sliding groove 201 is a columnar groove with a cross-section of any other arbitrary shape, such as a cylindrical groove, and the first sliding part 140 is a columnar body with a cross-section of any other arbitrary shape, such as a cylinder.

[0359] In some implementations of this technical solution embodiment, refer to Figure 9 , Figure 15 or refer to Figure 78 , Figure 81 The first support member 100 includes a first support body and a first damping protrusion 110 protruding from the first support body. The first damping protrusion 110 makes damping contact with the first sliding groove 201, so that the first support member 100 and the first sliding groove 201 can form damping contact. The advantage of providing the first damping protrusion 110 is that it can provide frictional damping for the first support member 100 and the second support member 200 at any position where the first damping protrusion 110 makes damping contact with the first sliding groove 201.

[0360] For example, the first damping protrusion 110 protrudes from the first support body, and the first support body is fitted into the first sliding groove 201. One implementation of damping contact between the first support member 100 and the second support member 200 is that only the first damping protrusion 110 makes damping contact with the first sliding groove 201, while the first support body does not contact the first sliding groove 201 (there is a gap between the first support body and the first sliding groove 201). For instance, the first damping protrusion 110 is strip-shaped, encircles the first support body, or consists of multiple protrusions spaced apart. In this implementation, the frictional force between the first support member 100 and the second support member 200 is entirely generated by the damping contact between the first damping protrusion 110 and the first sliding groove 201.

[0361] Another way to achieve damped contact between the first support member 100 and the second support member 200 is that the first damping protrusion 110 makes damped contact with the second support member 200. Due to the shape of the first damping protrusion 110, when the first damping protrusion 110 makes damped contact with the first sliding groove 201, the first support body of the first support member 100 also makes damped contact with the first sliding groove 201. In this implementation, the friction between the first support member 100 and the second support member 200 is generated by the damping contact between the first damping protrusion 110 and the first sliding groove 201, and the damping contact between the first support body and the first sliding groove 201.

[0362] For example, the first damping protrusion 110 makes damping contact with the first tension surface 201a so that the first support 100 can be positioned on the second support 200. The first sliding groove 201 has opposing first tension surfaces 201a and second tension surfaces 201b, which are used to confine the first support 100 within the first sliding groove 201. In this case, the first support body makes damping contact with the second tension surface 201b.

[0363] For example, the number of first damping protrusions 110 is 1, 2, 3, 4, etc.

[0364] Understandably, the first support member 100 can be positioned on the second support member 200 by the first damping protrusion 110.

[0365] For example, the first damping protrusion 110 is located near or at the second end of the first support 100.

[0366] In other examples, the first support 100 is positioned on the second support 200 by direct damping contact between the outer wall of the first sliding part 140 and the first sliding groove 201.

[0367] In some implementations of this technical solution embodiment, refer to Figure 9 , 12 15, etc., the first support body is provided with a first deformation opening 101 and a first cantilever 120 formed by extending from the edge of the first deformation opening 101. A first damping protrusion 110 protrudes from the first cantilever 120. The first cantilever 120 is configured to apply an elastic force to the first damping protrusion 110 so that the first damping protrusion 110 makes damping contact with the first sliding groove 201. The first deformation opening 101 serves as the deformation space of the first cantilever 120. On the one hand, when the first damping contact protrusion makes damping contact with the first sliding groove 201, the first deformation opening 101 serves as the deformation space of the first cantilever 120, avoiding excessive damping force between the first support member 100 and the second support member 200. On the other hand, when the first support member 100 is installed into the first sliding groove 201, the first deformation opening 101 serves as the deformation space of the first cantilever 120, making it easy for the first support member 100 to be installed into the second support member 200.

[0368] For example, the first deformation opening 101 is provided on the first support body of the first support member 100.

[0369] For example, the first deformation opening 101 is provided through the first support member 100.

[0370] For example, the first cantilever 120 is located within the first deformation opening 101 and does not protrude from the outer wall of the first support body. This arrangement makes installation easier. (More preferably, the first cantilever 120 is flush with the outer wall of the first support body).

[0371] In some implementations of this technical solution embodiment, refer to Figure 9 , 15The first sliding groove 201 has two first sides 201c extending along the sliding direction of the first support member 100. The distance between the two first sides 201c is the maximum width of the first sliding groove 201. There are two first damping protrusions 110. The two first damping protrusions 110 slide dampingly on the inner wall of the first sliding groove 201 to form two first damping tracks. The two first damping contact tracks are close to or located on the two first sides 201c. The advantage of this arrangement is that the damping force on the first support member 100 can act on itself as a whole, making the telescopic bracket more stable during telescopic movement.

[0372] For example, the first support body is symmetrical about the first symmetry plane, which is parallel to the extension direction of the support body 1a. When the first support member 100 is assembled into the first sliding groove 201, the first axis is located in the first symmetry plane, and the number of the first damping protrusions 110 is 2, with the 2 first damping protrusions 110 being symmetrical about the first symmetry plane.

[0373] For example, the two first damping contact tracks are located on the first tension surface 201a of the first sliding groove 201.

[0374] In some implementations of this technical solution, referring to 9, 15, etc., the first support body includes a first body 130 and a first sliding part 140 protruding from the first body 130. The first sliding part 140 is adapted to the first sliding groove 201. The first body 130 and the first sliding groove 201 have a first gap. The first sliding part 140 is slidably installed in the first sliding groove 201 so that the first support member 100 is slidable relative to the first sliding groove 201. A first damping protrusion 110 protrudes from the first sliding part 140 and makes damping contact with the inner wall of the first sliding groove 201. The first body 130 is fitted in the first sliding groove 201. The advantage of setting the first sliding part 140 is that it makes the first support member 100 more stable when sliding with the first sliding groove 201, and reduces the shaking of the first support member 100 relative to the first sliding groove 201. On the other hand, the first support body slides with the first sliding part 140 and the first sliding groove 201, which reduces the frictional resistance between the first support member 100 and the second support member 200, and makes it easier to stretch or store the telescopic support leg 2a.

[0375] For example, the first sliding groove 201 has a first stretching surface 201a and a second stretching surface 201b. The first stretching surface 201a and the second stretching surface 201b extend in the same direction. The first stretching surface 201a and the second stretching surface 201b restrict the first sliding part 140 within the first sliding groove 201 so that the first support member 100 can slide relative to the second support member 200. For example, the cross-section of the first stretching surface 201a is arc-shaped, and the cross-section of the second stretching surface 201b is a plane or a folded surface, etc.

[0376] For example, the first clearance opening 2010 penetrates the second stretching surface 201b.

[0377] For example, the cross-section of the first sliding groove 201 is adapted to the cross-section of the first sliding part 140.

[0378] For example, the length of the first sliding part 140 along the sliding direction is 30%-100% (e.g., 30%, 50%, 70%, 100%, etc.) of the maximum width of the first sliding groove 201.

[0379] For example, the first sliding groove 201 is a columnar groove, the first sliding groove 201 has a first axis, and the first sliding part 140 is circumferentially fixed relative to the first sliding groove 201 around the first axis.

[0380] For example, the cross-section of the first sliding groove 201 is "c" shaped, and the cross-section of the first sliding part 140 is "c" shaped.

[0381] For example, the cross-section of the first sliding groove 201 is semi-circular, elliptical, polygonal, etc., and correspondingly, the cross-section of the first sliding part 140 is semi-circular, elliptical, polygonal, etc.

[0382] In other examples, the first groove is a columnar groove with any other cross-sectional shape, such as a cylindrical groove, and correspondingly, the first sliding part 140 is a columnar body with any other cross-sectional shape, such as a cylinder.

[0383] In other examples, the first sliding portion 140 is coaxially rotatable relative to the first sliding groove 201.

[0384] It is understandable that when the first support member 100 and the second support member 200 are only slidably engaged by the first sliding part 140 and the first sliding groove 201, the first support member 100 can be slidably installed on the second support member 200.

[0385] In some implementations of this technical solution embodiment, refer to Figure 9 , 15 The first sliding part 140 is provided with a first deformation opening 101 and a first cantilever 120 formed by extending from the edge of the first deformation opening 101. A first protrusion protrudes from the first cantilever 120. The first cantilever 120 is configured to apply an elastic force to the first damping protrusion 110 so that the first damping protrusion 110 makes damping contact with the first sliding groove 201. The first deformation opening 101 serves as the deformation space of the first cantilever 120.

[0386] For example, the first deformation opening 101 is provided through the first sliding part 140.

[0387] For example, the first cantilever 120 is located inside the first deformation opening 101 and does not protrude from the outer wall of the first sliding portion 140. The advantage of this arrangement is that it is easier to install. More preferably, the outer wall of the first cantilever 120 is flush with the outer wall of the first sliding portion 140.

[0388] In some implementations of this technical solution embodiment, refer to Figure 9 , 15 The first sliding groove 201 has two first sides 201c extending along the sliding direction of the first support member 100. The distance between the two first sides 201c is the maximum width of the first sliding groove 201. There are two first damping protrusions 110. The two first damping protrusions 110 slide against the inner wall of the first sliding groove 201 to form two first damping tracks. The two first damping contact tracks are close to or located on the two first sides 201c. The advantage of this arrangement is that it makes the first support member 100 more stable when sliding relative to the second support member 200.

[0389] For example, the first sliding part 140 is symmetrical about a first symmetry plane, which is parallel to the extension direction of the support body 1a. When the first support member 100 is assembled into the first sliding groove 201, the first axis is located in the first symmetry plane, the number of first damping protrusions 110 is 2, the 2 first damping protrusions 110 are symmetrical about the first symmetry plane, and the axis of the first sliding groove 201 is located in the first symmetry plane.

[0390] For example, the two first damping contact tracks are located on the first tension surface 201a of the first sliding groove 201.

[0391] For example, the line connecting any two points on the damping contact surfaces of the two first damping protrusions 110 forms a first connecting line, and the first support member 100 extends along the first straight line. The angle between the first connecting line and the first straight line is greater than or equal to 75° and less than or equal to 90° (e.g., 75°, 80°, 85°, 90°, etc.). The advantage of this arrangement is that it makes the first support member 100 have a more stable positioning effect relative to the second support member 200.

[0392] For example, the length of the first connecting line is 70%-100% (e.g., 70%, 80%, 90%, 100%, etc.) of the maximum width of the first sliding groove 201. The advantage of this setting is that, on the one hand, it makes the sliding of the first support member 100 relative to the second support member 200 more stable, and on the other hand, it makes the positioning effect of the first support member 100 relative to the second support member 200 more stable.

[0393] For example, the first sliding groove 201 has two first sides 201c extending along the sliding direction of the first support member 100. The distance between the two first sides 201c is the maximum width of the first sliding groove 201. The first sliding groove 201 includes a first sliding sub-groove 201d and a second sliding sub-groove 201e. The two first sides 201c are located in the first sliding sub-groove 201d and the second sliding sub-groove 201e, respectively. The first sliding part 140 has a first sliding body 141 and a second sliding body 142. The first sliding body 141 is adapted to the first sliding sub-groove 201d, and the second sliding body 142 is adapted to the second sliding sub-groove 201e. The first sliding body 141 is slidably installed in the first sliding sub-groove 201d, and the second sliding body 142 is slidably installed in the second sliding sub-groove 201e.

[0394] For example, when the telescopic leg 2a is at its longest length, the first body 130 extends from the second support 200, and when the telescopic leg 2a is at its shortest length, the first body 130 is contained within the second support 200.

[0395] In some implementations of this technical solution embodiment, refer to Figure 17 The first sliding part 140 is provided with a first limiting wall 102, and the second support member 200 has a second limiting wall 202. When the length of the telescopic support leg 2a is the longest, the first limiting wall 102 and the second limiting wall 202 abut against each other.

[0396] For example, the first sliding part 140 protrudes from the first body 130, and the first limiting wall 102 is located on the side of the first sliding part 140.

[0397] In some implementations of this technical solution embodiment, refer to 17, or refer to Figure 80 , Figure 81 , Figure 82 The first main body 130 has a first positioning protrusion 131, and the second support member 200 has a second positioning protrusion 221. During the sliding process of the first support member 100 relative to the second support member 200, the first positioning protrusion 131 can abut against or slide past the second positioning protrusion 221. When the first positioning protrusion 131 abuts against the second positioning protrusion 221, the first support member 100 is positioned relative to the second support member 200 when the telescopic leg 2a is in the supported state. The advantage of setting the first positioning protrusion 131 and the second positioning protrusion 221 is that when the first positioning protrusion 131 abuts against the second positioning protrusion 221, it provides additional supporting force for the first support member 100 relative to the second support member 200, further enhancing the stability of the telescopic leg 2a in the supported state. Furthermore, the first positioning protrusion 131 can slide past the second positioning protrusion 221 without affecting the storage of the telescopic leg 2a, and after the telescopic leg 2a is stored, it does not affect the extension of the telescopic leg 2a.

[0398] For example, the first positioning protrusion 131 protrudes from the first body 130, and the second positioning protrusion 221 protrudes from the second positioning member 220.

[0399] For example, the first positioning protrusion 131 is the sidewall of the groove of the first body 130, and the second positioning protrusion 221 is the sidewall of the groove of the first body 130.

[0400] For example, the number of first positioning protrusions 131 can be 1, 2, 3, etc., and the number of second positioning protrusions 221 can be 1, 2, 3, etc.

[0401] For example, when the first positioning protrusion 131 abuts against the second positioning protrusion 221, it provides additional bearing force for the first support 100 relative to the second support 200.

[0402] For example, the first positioning protrusion 131 sliding over the second positioning protrusion 221 can mean that when the telescopic leg 2a is in a supported state, with the first positioning protrusion 131 abutting against the second positioning protrusion 221, and when the pressure on the telescopic leg 2a is large enough, the first positioning protrusion 131 slides over the second positioning protrusion 221, so that the first support member 100 can be housed in the second support member 200.

[0403] For example, the first positioning protrusion 131 sliding over the second positioning protrusion 221 can also refer to the telescopic leg 2a being in a retracted state, with the second positioning protrusion 221 not abutting against the first positioning protrusion 131, and the second positioning protrusion 221 being located between the first end of the first support member 100 and the first positioning protrusion 131. When the telescopic leg 2a is subjected to a sufficiently large pulling force, the first support member 100 extends relative to the second support member 200, and the first positioning protrusion 131 slides over the second positioning protrusion 221. After the first positioning protrusion 131 slides over the second protrusion, the first positioning protrusion 131 can abut against the second positioning protrusion 221 to achieve the first support member 100 being positioned relative to the second support member 200 in the supported state.

[0404] Obviously, the abutment of the first positioning protrusion 131 and the second positioning protrusion 221 enables the telescopic leg 2a to position the first support member 100 on the second support member 200 at a specific length.

[0405] For example, in one implementation, the telescopic leg 2a enables the first support member 100 to be positioned on the second support member 200 through the cooperation of the first positioning protrusion 131 and the second positioning protrusion 221.

[0406] Understandably, during the process of the first positioning protrusion 131 sliding over the second positioning protrusion 221, the first positioning protrusion 131 deforms, and / or the second positioning protrusion 221 deforms, thereby allowing the first positioning protrusion 131 to slide over the second positioning protrusion 221.

[0407] In some implementations of this technical solution embodiment, refer to Figure 17 Wait, or refer to Figure 80 , Figure 81 , Figure 82 The second support member 200 includes a second main body 210 and a second positioning member 220. The second positioning member 220 is disposed on the second main body 210 and located between the first main body 130 and the second main body 210. The first main body 130 is slidably mounted on the second positioning member 220 so that the first support member 100 is slidable relative to the second support member 200. The first support member 100 is sleeved on the second main body 210, and a second positioning protrusion 221 is disposed on the second positioning member 220. The advantage of the above arrangement is that the first support member 100 is slidably mounted on the second positioning member 220 and is also slidably mounted on the first sliding groove 201, which improves the stability of the first support member 100 when sliding.

[0408] For example, the first body 130 of the first support member 100 is slidably mounted on the second positioning member 220.

[0409] For example, the second positioning element 220 is detachably disposed on the second body 210.

[0410] For example, the second positioning element 220 is in the form of a thin sheet, and the second positioning element 220 surrounds or partially surrounds the first body 130.

[0411] For example, the second positioning element 220 is in the form of a thin sheet and is attached to the inner wall of the first sliding groove 201.

[0412] For example, the second positioning member 220 surrounds to form the second sliding groove 203, and the first body 130 of the first support member 100 is slidably sleeved in the second sliding groove 203. The first sliding groove 201 and the second sliding groove 203 are coaxial or have the same extension direction. Obviously, the second sliding groove 203 is a tension groove (i.e., a columnar groove).

[0413] For example, the second sliding groove 203 is a columnar groove, and the first body 130 is fixed circumferentially around the second sliding groove 203.

[0414] For example, the second positioning member 220 has opposing third stretching surfaces 203a and fourth stretching surfaces 203b, which together constrain the first body 130 within the second sliding groove 203. For instance, the second positioning protrusion 221 protrudes from the fourth stretching surface 203b.

[0415] For example, the first clearance opening is connected to the second sliding groove.

[0416] In other examples, the second positioning protrusion 221 is provided on the second body 210, for example, the second positioning protrusion 221 is integrally provided on the second body 210.

[0417] For example, the second positioning member 220 is fixedly installed on the second body 210, and the second positioning member 220 is detachable relative to the second body 210.

[0418] For example, the second positioning member 220 can be inserted into the first sliding groove 201 and fixed to the second body 210.

[0419] For example, the second positioning member 220 is a thin sheet with a second opening 204. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the second positioning member 220 is compressed and deformed as a whole, making it easier for the second positioning member 220 to be inserted into the first sliding groove 201.

[0420] For example, the second positioning member 220 is a thin sheet with a second opening 204. The second opening 204 extends from the outer wall of the second positioning member 220 to the fourth stretching surface 203b. When it is necessary to disassemble the second positioning member 220, the second positioning member 220 is compressed to reduce the size of the second opening 204, so that the second positioning member 220 can be removed from the second body 210.

[0421] It is understandable that the sliding engagement between the first support member 100 and the second support member 200 can be achieved solely through the sliding engagement between the first support member 100 and the second positioning member 220.

[0422] In some implementations of this technical solution embodiment, refer to Figure 2 etc., or refer to Figure 81 The first body 130 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first body 130 extends from the second support member 200, and the first positioning protrusion 131 is close to or located at the first end of the first body 130. The advantage of this arrangement is that it allows the telescopic leg 2a to have a longer support length, and the first positioning protrusion 131 makes the telescopic leg 2a more stable.

[0423] For example, when the telescopic leg 2a is at its longest length, the first positioning protrusion 131 abuts against the second positioning protrusion 221.

[0424] In other examples, the first support member 100 has a first end and a second end, and when the telescopic leg 2a is at its longest length, the first end of the first support member 100 extends from the second support member 200, and the first positioning protrusion 131 is close to or located at the first end of the first support member 100.

[0425] In some implementations of this technical solution embodiment, refer to Figure 12 , 18 Wait, or refer to Figure 81 , 82 The first positioning protrusion 131 has two components, and the second positioning protrusion 221 has two components. The second positioning component 220 has a second sliding groove 203 adapted to the first body 130. The first body 130 is slidably mounted on the second sliding groove 203. The second sliding groove 203 has two first side edges 203c along the sliding direction of the first body 130. The distance between the two first side edges 203c is the maximum width of the second sliding groove 203. The two second positioning protrusions 221 are located at or near the two first side edges 203c. The advantage of this arrangement is that it makes the first support 100 more stable when positioned relative to the second support 200.

[0426] For example, the two first side edges 203c are located on opposite sides of the third stretching surface 203a.

[0427] For example, the first body 130 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first body 130 extends from the second support 200, and the first positioning protrusion 131 is close to or located at the first end of the first body 130.

[0428] For example, the second support member 200 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first body 130 extends from the first end of the second support member 200, and the second positioning protrusion 221 is close to the second end of the second support member 200.

[0429] In other examples, the first support member 100 has a first positioning protrusion 131 and the second support member 200 has a second positioning protrusion 221, during which the first positioning protrusion 131 can slide past the second positioning protrusion 221.

[0430] In other examples, the first body 130 is provided with a first positioning protrusion 131, and the second body 210 is provided with a second positioning protrusion 221.

[0431] In some implementations of this technical solution embodiment, refer to Figure 12 , 18 Wait, or refer to Figure 81The first positioning protrusion 131 has two opposing first sidewalls 131a. The distance between the two first sidewalls 131a narrows from the bottom to the top of the first positioning protrusion 131. The first sidewalls 131a can abut against the second positioning protrusion 221. During the process of the first positioning protrusion 131 sliding past the second positioning protrusion 221, the first sidewalls 131a and the second positioning protrusion 221 make sliding contact, and the top of the first positioning protrusion 131 makes sliding contact with the second positioning protrusion 221. The advantage of this design is that during the process of the first positioning protrusion 131 sliding past the second positioning protrusion 221, wear on both the first positioning protrusion 131 and the second positioning protrusion 221 is less likely to occur.

[0432] For example, the top of the first sidewall 131a and the top of the first positioning protrusion 131 are gradually transitioned, for example, the top of the first sidewall 131a and the top of the first positioning protrusion 131 are smoothly curved, or for example, the top of the first sidewall 131a and the top of the first positioning protrusion 131 are inclined.

[0433] It is understandable that when the telescopic support leg 2a is in the supported state, one of the first sidewalls 131a of the first positioning protrusion 131 abuts against the second positioning protrusion 221.

[0434] In other implementations of this technical solution embodiment, refer to Figure 12 , 18 Wait, or refer to Figure 82 The second positioning protrusion 221 has two opposing second sidewalls 205. The distance between the two second sidewalls 205 narrows from the bottom to the top of the second positioning protrusion 221. The first positioning protrusion 131 can abut against the second sidewalls 205. During the process of the first positioning protrusion 131 sliding past the second positioning protrusion 221, the first positioning protrusion 131 and the second sidewalls 205 make sliding contact, and the top of the first positioning protrusion 131 also makes sliding contact. The advantage of this design is that during the process of the first positioning protrusion 131 sliding past the second positioning protrusion 221, wear on both the first positioning protrusion 131 and the second positioning protrusion 221 is less likely to occur.

[0435] For example, the top of the second sidewall 205 and the top of the second positioning protrusion 221 are gradually transitioned, for example, the top of the second sidewall 205 and the top of the second positioning protrusion 221 are smoothly curved, or for example, the top of the second sidewall 205 and the top of the second positioning protrusion 221 are inclined.

[0436] It is understandable that when the first positioning protrusion 131 abuts against the second positioning protrusion 221, the first positioning protrusion 131 abuts against one of the second sidewalls 205 of the second positioning protrusion 221.

[0437] In some implementations of this technical solution embodiment, refer to Figure 17As shown in the figure, or referring to the reference image, the first sliding part 140 is provided with a first limiting wall 102, and the second positioning member 220 has a second limiting wall 202. When the telescopic leg 2a is at its longest length, the first limiting wall 102 and the second limiting wall 202 abut against each other, and the first positioning protrusion 131 is close to the first limiting wall 102. The advantage of this arrangement is that the telescopic leg 2a can be quickly extended to its longest length, and at its longest length (or close to its longest length), the first positioning protrusion 131 abuts against the second positioning protrusion 221, making the telescopic leg 2a more stable when supported.

[0438] For example, when the telescopic leg 2a is at its longest length, the first positioning protrusion 131 abuts against the second positioning protrusion 221.

[0439] For example, when the telescopic leg 2a is at its longest length, the first positioning protrusion 131 and the second positioning protrusion 221 have a gap. When the telescopic leg 2a is at its longest length, the first support member 100 can slide a short distance to abut against the second positioning protrusion 221.

[0440] The first sliding groove 201 is a columnar groove, and the first sliding part 140 is circumferentially fixed relative to the first sliding groove 201. The second positioning member 220 is provided with a second sliding groove 203, which is a columnar groove, and the first main body 130 is circumferentially fixed relative to the second sliding groove 203.

[0441] In some implementations of this technical solution embodiment, refer to Figure 5 The first support member 100 includes a first main body 130 and a first sliding portion 140 disposed on the first main body 130. The second positioning member 220 is provided with a second sliding groove 203, and the first main body 130 is slidably mounted in the second sliding groove 203. The second main body 210 is provided with a first sliding groove 201, and the first sliding portion 140 is slidably mounted in the first sliding groove 201. The advantage of this arrangement is that two sliding engagements are formed between the first support member 100 and the second support member 200, making the first support member 100 more stable when sliding relative to the second support member 200.

[0442] For example, the first support member 100 has a first end and a second end, and the second support member 200 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first support member 100 extends from the first end of the second support member 200. The first sliding part 140 is located at or near the second end of the first support member 100, and the second positioning member 220 is near or located at the first end of the second support member 200.

[0443] For example, the second sliding groove 203 is a columnar groove, the first main body 130 is circumferentially fixed relative to the second sliding groove 203, the first sliding groove 201 is a columnar groove, and the first sliding part 140 is circumferentially fixed relative to the first sliding groove 201.

[0444] For example, the cross-section of the second sliding groove 203 is "c" shaped, and the cross-section of the first body 130 is "c" shaped.

[0445] For example, the cross-section of the second sliding groove 203 is semi-circular, elliptical, polygonal, etc., and correspondingly, the cross-section of the first body 130 is semi-circular, elliptical, polygonal, etc.

[0446] In other examples, the second sliding groove 203 is a columnar groove with other arbitrary cross-sectional shapes, such as a cylindrical groove, and correspondingly, the first body 130 is a columnar body with other arbitrary cross-sectional shapes, such as a cylinder.

[0447] In other examples, the first body 130 can rotate coaxially with respect to the second sliding groove 203.

[0448] In some implementations of this technical solution embodiment, refer to Figure 11 , 18 The first support member 100 has a third positioning protrusion 132. During the sliding process of the first support member 100 relative to the second support member 200, the second positioning protrusion 221 can abut against or slide past the third positioning protrusion 132. The second support member 200 also has a second positioning protrusion 221. When the telescopic leg 2a is in the retracted state, the third positioning protrusion 132 abuts against the second positioning protrusion 221, which can prevent the first support member 100 from sliding out of the second support member 200. The advantage of this arrangement is that when the first support member 100 is housed in the second support member 200, the first support member 100 can be kept in the second support member 200, preventing the first support member 100 from sliding relative to the second support member 200, thereby affecting the housing of the telescopic leg 2a.

[0449] For example, the third positioning protrusion 132 protrudes from the first support member 100, or the third positioning protrusion 132 is the sidewall of the groove of the first support member 100.

[0450] For example, the second positioning protrusion 221 protrudes from the first support member 100, or the third positioning protrusion 132 is the sidewall of the groove of the first support member 100.

[0451] For example, the number of third positioning protrusions 132 can be 1, 2, 3, etc., and the number of second positioning protrusions 221 can be 1, 2, 3, etc.

[0452] For example, when the third positioning protrusion 132 abuts against the second positioning protrusion 221, it provides additional holding force for the first support 100 to be housed in the second support 200, thereby preventing the first support 100 from sliding out of the second support 200.

[0453] For example, the third positioning protrusion 132 sliding over the second positioning protrusion 221 can mean that when the telescopic leg 2a is in the retracted state, with the third positioning protrusion 132 abutting against the second positioning protrusion 221, and the telescopic leg 2a is subjected to a sufficiently large pulling force, the third positioning protrusion 132 slides over the second positioning protrusion 221, thereby allowing the first support member 100 to extend from the second support member 200.

[0454] For example, the third positioning protrusion 132 sliding past the second positioning protrusion 221 can also refer to the following: when the telescopic bracket is in the supported state, the third positioning protrusion 132 and the second positioning protrusion 221 do not abut against each other. When the pressure on the telescopic leg 2a is large enough, the first support member 100 is retracted relative to the second support member 200, the third positioning protrusion 132 slides past the second positioning protrusion 221, and after the third positioning protrusion 132 slides past the second positioning protrusion 221, the third positioning protrusion 132 can abut against the second positioning protrusion 221, so that when the telescopic leg 2a is in the retracted state, the first support member 100 remains on the second support member 200.

[0455] For example, in one implementation, the telescopic leg 2a enables the first support member 100 to be housed in the second support member 200 through the cooperation of the third positioning protrusion 132 and the second positioning protrusion 221.

[0456] It is understandable that during the process of the third positioning protrusion 132 sliding over the second positioning protrusion 221, the third positioning protrusion 132 deforms, and / or the second positioning protrusion 221 deforms, thereby allowing the third positioning protrusion 132 to slide over the second positioning protrusion 221.

[0457] In some implementations of this technical solution embodiment, refer to Figure 18 The second support member 200 includes a second main body 210 and a second positioning member 220. The second positioning member 220 is disposed on the second main body 210 and is located between the first support member 100 and the second main body 210. A second positioning protrusion 221 is disposed on the second positioning member 220. The first support member 100 is slidably mounted on the second positioning member 220 so that the first support member 100 is slidable relative to the second support member 200. The first support member 100 is sleeved on the second main body 210.

[0458] For example, the first support member 100 is slidably mounted on the second positioning member 220.

[0459] For example, the second positioning member 220 is in the form of a sheet, and the second positioning member 220 surrounds or partially surrounds the first support member 100.

[0460] For example, the second positioning member 220 surrounds to form the second sliding groove 203, and the first support member 100 is slidably sleeved in the second sliding groove 203. The first sliding groove 201 and the second sliding groove 203 are coaxial or have the same extension direction.

[0461] For example, the second sliding groove 203 is a columnar groove, and the first support member 100 is fixed circumferentially around the second sliding groove 203.

[0462] For example, the second positioning member 220 has opposing third stretching surfaces 203a and fourth stretching surfaces 203b, which together constrain the first support member 100 within the second sliding groove 203. For instance, the second positioning protrusion 221 protrudes from the fourth stretching surface 203b.

[0463] For example, the second positioning member 220 is fixedly installed on the second body 210, and the second positioning member 220 is detachable relative to the second body 210.

[0464] For example, the second body 210 is provided with a first sliding groove 201, and the second positioning member 220 can be inserted into the first sliding groove 201 of the first body 130.

[0465] For example, the second positioning member 220 is a thin sheet with a second opening 204. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the second positioning member 220 is compressed and deformed as a whole, making it easier for the second positioning member 220 to be inserted into the first sliding groove 201.

[0466] For example, the second positioning member 220 is a thin sheet with a second opening 204. The second opening 204 extends from the outer wall of the second positioning member 220 to the fourth stretching surface 203b. When it is necessary to disassemble the second positioning member 220, the second positioning member 220 is compressed to reduce the size of the second opening 204, so that the second positioning member 220 can be removed from the second body 210.

[0467] In other examples, a second positioning protrusion 221 is provided on the second body 210.

[0468] In some implementations of this technical solution embodiment, refer to Figure 22 The first support member 100 is provided with a third limiting wall 104, and the second positioning member 220 is provided with a fourth limiting wall 206. When the length of the telescopic support leg 2a is at its shortest, the third limiting wall 104 and the fourth limiting wall 206 abut against each other; the third positioning protrusion 132 is close to the third limiting wall 104. The advantage of this arrangement is that it avoids the first support member 100 being excessively retracted into the second support member 200.

[0469] For example, the third limiting wall 104 is located at or near the first end of the first support 100, and more specifically, the third limiting wall 104 is near or located at the first end of the first body 130.

[0470] For example, the outer wall of the first body 130 is slidably sleeved on the second positioning member 220, and the third limiting wall 104 forms a step with the outer wall of the first body 130.

[0471] For example, the fourth limiting wall 206 is located at one end of the second positioning member 220.

[0472] For example, the first body 130 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first body 130 extends from the second support member 200, and the second positioning member 220 extends to form a rim 222. The rim 222 covers the first end of the first body 130, and the fourth limiting wall 206 is provided on the rim 222.

[0473] In some implementations of this technical solution embodiment, refer to Figure 11 , 18 There are two third positioning protrusions 132 and two second positioning protrusions 221. The second positioning member 220 has a second sliding groove 203 adapted to the first body 130. The first body 130 is slidably mounted on the second sliding groove 203. The second sliding groove 203 has two first side edges 203c along the sliding direction of the first body 130. The distance between the two first side edges 203c is the maximum width of the second sliding groove 203. The two second positioning protrusions 221 are located at or near the two first side edges 203c. The advantage of this arrangement is that it makes the first support member 100 more stable when it abuts against the third positioning protrusions 132.

[0474] For example, two second positioning protrusions 221 are provided on the fourth stretching surface 203b.

[0475] In some implementations of this technical solution embodiment, refer to Figure 11 , 18 The first support member 100 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first support member 100 extends from the second support member 200, and the third positioning protrusion 132 is close to or located at the second end of the first support member 100. The advantage of this arrangement is that when the telescopic leg 2a is retracted to its shorter length, the first support member 100 abuts against the third positioning protrusion 132.

[0476] For example, when the length of the telescopic leg 2a is at its shortest, the third positioning protrusion 132 abuts against the second positioning protrusion 221.

[0477] In some implementations of this technical solution embodiment, refer to Figure 11, 18 The first support member 100 is sleeved on the second support member 200, and the first support member 100 is slidable relative to the second support member 200.

[0478] The first support member 100 can be sleeved on the second support member 200 in any of the following ways, or a combination of the following ways:

[0479] 1. The first support member 100 is sleeved in the first sliding groove 201 of the second support member 200;

[0480] 2. The first support member 100 is fitted into the second sliding groove 203 of the second support member 200.

[0481] The first support member 100 can be slidable relative to the second support member 200 in any of the following ways, or a combination thereof:

[0482] 1. The first support member 100 is slidably installed in the first sliding groove 201. For example, the first support member 100 can slide relative to the second support member 200 through the cooperation of the first sliding part 140 and the first sliding groove 201.

[0483] 2. The first support member 100 is slidably installed in the second sliding groove 203. For example, the first support member 100 can slide relative to the second support member 200 through the cooperation between the first main body 130 and the second sliding groove 203.

[0484] In some implementations of this technical solution embodiment, refer to Figure 11 The third positioning protrusion 132 has two opposing third sidewalls 132a. From the bottom end to the top end of the third positioning protrusion 132, the distance between the two third sidewalls 132a narrows. The third sidewalls 132a can abut against the second positioning protrusion 221. During the process of the third positioning protrusion 132 sliding past the second positioning protrusion 221, the third sidewalls 132a and the second positioning protrusion 221 slide in contact. The top end of the third positioning protrusion 132 slides in contact with the second positioning protrusion 221.

[0485] For example, the top of the third sidewall 132a and the top of the third positioning protrusion 132 are gradually transitioned, for example, the top of the third sidewall 132a and the top of the third positioning protrusion 132 are smoothly curved, or for example, the top of the third sidewall 132a and the top of the third positioning protrusion 132 are inclined.

[0486] It is understandable that when the third positioning protrusion 132 abuts against the second positioning protrusion 221, one of the third sidewalls 132a of the third positioning protrusion 132 abuts against the second positioning protrusion 221.

[0487] In other implementations of this technical solution embodiment, refer to Figure 18 The second positioning protrusion 221 has two opposing second sidewalls 205. The distance between the two second sidewalls 205 narrows from the bottom end to the top end of the second positioning protrusion 221. The third positioning protrusion 132 can abut against the second sidewall 205. During the process of the third positioning protrusion 132 sliding past the second positioning protrusion 221, the third positioning protrusion 132 slides in contact with the second sidewall 205 and slides in contact with the top end of the second positioning protrusion 221.

[0488] For example, the top of the second sidewall 205 and the top of the second positioning protrusion 221 are gradually transitioned, for example, the top of the second sidewall 205 and the top of the second positioning protrusion 221 are smoothly curved, or for example, the top of the second sidewall 205 and the top of the second positioning protrusion 221 are inclined.

[0489] It is understandable that when the third positioning protrusion 132 abuts against the second positioning protrusion 221, the third positioning protrusion 132 abuts against one of the second sidewalls 205 of the second positioning protrusion 221.

[0490] In other implementations of this technical solution embodiment, refer to Figure 1-27 The first support member 100 may be positioned on the second support member 200 such that the telescopic leg 2a may support the support rod 1, not limited to any one of the following situations, or a combination of the following situations:

[0491] 1. The first support member does not have a protruding structure. The first support member is directly damped in contact with the first sliding groove 201. For example, the outer wall of the first sliding part 140 is directly damped in contact with the first sliding groove 201 (for example, the first sliding part 140 is tightly fitted with the first sliding groove 201) so that the first support member 100 can be positioned on the second support member 200.

[0492] 2. The first support member 100 has a protruding structure, for example, the first support member 100 has a first damping protrusion 110 that makes damping contact with the first sliding groove 201, so that the first support member 100 can be positioned on the second support member 200.

[0493] 3. The first support member does not have a protruding structure. The first support member 100 is in damped contact with the second sliding groove 203. Specifically, the first body 130 is in direct damped contact with the second sliding groove 203 (e.g., the first body 130 and the second sliding groove 203 are tightly fitted), so that the first support member 100 can be positioned on the second support member 200.

[0494] 4. Both the first support member 100 and the second support member 200 have protruding structures. For example, the first positioning protrusion 131 abuts against the second positioning protrusion 221 so that the first support member 100 can be positioned on the second support member 200.

[0495] In some implementations of this technical solution embodiment, refer to Figure 26 The second support member 200 includes a second main body 210 and an edging 222. The second main body 210 is provided with a first sliding groove 201, and the first support member 100 is slidable relative to the first sliding groove 201. The second main body 210 has a first end and a second end. When the telescopic support leg 2a extends, the first support member 100 extends from the first end of the second main body 210, and the edging 222 covers the first end of the second main body 210. The advantage of providing the edging 222 to the second support member 200 is that it makes the second support member 200 more aesthetically pleasing. Furthermore, since the second main body 210 is the main component of the second support member 200, the edging 222 can cover any burrs or sharp edges that may exist at the first end of the second main body 210, making it less likely to injure hands.

[0496] For example, the second body 210 is cast or stamped, and the edging 222 is a plastic part.

[0497] For example, the edging 222 completely covers the first end of the second body 210, or the edging 222 partially covers the first end of the second body 210.

[0498] For example, the outer wall of the second body 210 has a first edge 207a located at the first end of the second body 210, and the outer wall of the edging 222 has a second edge 207b aligned with the first edge 207a. This arrangement makes the second support 200 more aesthetically pleasing and less likely to scratch the user's hand. For instance, the first edge 207a and the second edge 207b may be completely flush or have a gap.

[0499] It is understandable that edge A is aligned with edge B, meaning that edge A is close to or fits against edge B, and there is no height difference between edge A and edge B.

[0500] For example, the outer wall of the edging 222 has a smooth transition. Along the direction of extension of the telescopic leg 2a, the edging 222 gradually narrows.

[0501] In some implementations of this technical solution embodiment, refer to Figure 26 The first support member 100 has a third limiting wall 104, and the second support member 200 has a fourth limiting wall 206. When the telescopic leg 2a is at its shortest length, the third limiting wall 104 and the fourth limiting wall 206 abut against each other. The fourth limiting wall 206 is located on the edging 222. The edging 222 is used both to cover the second end of the second main body 210 and to abut against the third limiting wall 104, making the structure of the telescopic leg 2a more compact.

[0502] For example, the fourth limiting wall 206 is opposite to the first holding wall 208.

[0503] In some implementations of this technical solution embodiment, refer to Figure 1-6 The multi-leg bracket also includes a first mounting portion 5 disposed on the support rod 1. The first support member 100 includes a first body 130 and a first connecting portion 150. The first body 130 is fitted inside the second support member 200. The first body 130 has a first end and a second end. When the telescopic leg 2a is at its longest, the first end of the first body 130 extends out from the second support member 200. The first connecting portion 150 is disposed on the first body 130 (for example, the first connecting portion 150 is disposed on the first end of the first body 130). The first connecting portion 150 is rotatably mounted on the first mounting portion 5 so that the angle between the telescopic leg 2a and the support rod 1 is adjustable. A third limiting wall 104 is disposed on the first connecting portion 150. The first connecting portion 150 is used both for rotatable connection with the first mounting portion 5 and for abutting against the edging 222, making the structure of the telescopic leg 2a more compact.

[0504] For example, the first mounting part 5 is integrally or fixedly mounted on the support rod 1, and the first connecting part 150 is rotatably mounted on the first mounting part 5 so that the angle between the telescopic leg 2a and the support rod 1 is adjustable.

[0505] For example, the first mounting part 5 is slidably mounted on the support rod 1, and one end of the first connecting rod 7 is rotatably connected to the support rod 1 and the other end is rotatably connected to the telescopic support leg 2a. The telescopic support leg 2a, the first mounting part 5, the support rod 1, and the first connecting rod 7 form a slider linkage mechanism. During the sliding process of the first mounting part 5 relative to the support rod 1, the angle between the telescopic support leg 2a and the support rod 1 changes.

[0506] In some implementations of this technical solution embodiment, refer to Figure 26 The second positioning member 220 has an edge 222. The advantage of this arrangement is that the second positioning member 220 is used both to slide with the first support member 100 and to cover the first end of the second body 210, making the structure of the telescopic leg 2a more compact.

[0507] For example, along the sliding direction of the first support member 100, the second positioning member 220 has a first end and a second end, and the edging 222 is located at the first end of the second positioning member 220.

[0508] In some implementations of this technical solution, the first body has a first end and a second end. When the length of the telescopic leg is at its longest, the first end of the first body extends out from the second support member. When the length of the telescopic leg is at its shortest, the first end of the first body is housed in the second support member.

[0509] For example, the first end of the first body is housed in the second positioning element or the second body.

[0510] In some implementations of this technical solution embodiment, refer to Figure 5 , 14 The first main body 130 is slidably mounted on the second positioning member 220 so that the first support member 100 is slidable relative to the second support member 200; when the telescopic leg 2a is at its shortest, the first end of the first main body 130 is housed in the second positioning member 220. The advantage of this arrangement is that it makes the structure of the telescopic leg 2a more compact and aesthetically pleasing.

[0511] In some implementations of this technical solution, referring to 11, 12, etc., the second main body 210 is provided with a first sliding groove 201, and the second positioning member 220 can be inserted into the first sliding groove 201 through the first end of the second main body 210. The edging 222 has a first retaining wall 208, which abuts against the first end of the second main body 210 to restrict the movement of the second positioning member 220 along a first direction, which is the direction in which the second positioning member 220 is inserted into the first sliding groove 201. The advantage of this arrangement is that, on the one hand, the second positioning member 220 is easy to install, and on the other hand, the edging 222 also has the function of restricting the second positioning member 220, making the structure of the telescopic support leg 2a more compact.

[0512] It is understood that the edging 222 has a covering wall covering the first end of the second body 210, and the first retaining wall 208 is part or all of the covering wall.

[0513] For example, the second retaining wall forms a step with the outer wall of the second positioning member 220.

[0514] It is understandable that when the first support member 100 retracts into the second support member 200, the first retaining wall 208 abuts against the first end of the second main body 210 to restrict the movement of the second positioning member 220 along the first direction.

[0515] For example, the second positioning member 220 is provided with a first limiting part 223. The second positioning member 220 can be slidably inserted into the first sliding groove 201. After the second positioning member 220 is inserted into the first sliding groove 201, the first limiting part 223 cooperates with the second limiting part 2019 to restrict the second positioning member 220 within the first sliding groove 201.

[0516] The second limiting part 2019 is a groove, and the first limiting part 223 is a protrusion. The first limiting part 223 is provided with a first sliding surface 209. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides past the second main body 210. Alternatively, the first limiting part 223 is a groove, the second limiting part 2019 is a protrusion, and the second limiting part 229 is provided with a second sliding surface. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides past the second positioning member 220.

[0517] In some implementations of this technical solution, the second positioning member 220 can position the first support member 100 on the second support member 200.

[0518] For example, the inner wall of the second positioning member 220 is in direct damping contact with the first body 130, so that the first support member 100 can be positioned on the second support member 200.

[0519] For example, the second positioning member 220 is provided with a second positioning protrusion 221, and the first body 130 is provided with a first positioning protrusion 131. The first positioning protrusion 131 abuts against the second positioning protrusion 221, which can make the first support member 100 positioned on the second support member 200.

[0520] In some implementations of this technical solution embodiment, refer to Figure 5 , 14 The second support member 200 has a second sliding groove 203 adapted to the first main body 130. The first main body 130 is slidably mounted in the second sliding groove 203 so that the first support member 100 is slidable relative to the second support member 200. The first main body 130 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first main body 130 extends out from the second support member 200. When the telescopic leg 2a is at its shortest length, the first end of the first main body 130 is retracted into the second sliding groove 203. The advantage of this arrangement is that the structure is more compact and aesthetically pleasing after the telescopic leg 2a is retracted.

[0521] For example, the second support member 200 includes a second body 210 and a second positioning member 220 disposed on the second body 210; a second sliding groove 203 is disposed on the second positioning member 220; the second positioning member 220 can position the first support member 100 on the second support member 200.

[0522] For example, when the telescopic leg 2a is at its shortest, the second positioning member 220 abuts against the third limiting wall 104.

[0523] In some implementations of this technical solution, referring to 22, when the length of the telescopic leg 2a is at its shortest, the second support member 200 abuts against the first connecting portion 150. The advantage of this arrangement is that it makes the structure of the telescopic leg 2a more compact.

[0524] In some implementations of this technical solution, when the length of the telescopic leg 2a is at its shortest, the outer wall of the second support member 200 is aligned with the outer wall of the first connecting portion 150. This arrangement has the advantage of making the structure more compact when the telescopic leg 2a is retracted.

[0525] It is understandable that aligning the wall surface of A with the wall surface of B means that the edges of the wall surface of A are close to or touching the edges of the wall surface of B, and there is no height difference (i.e., no step) at the junction or close to each other.

[0526] In some implementations of this technical solution, when the telescopic leg 2a and the support rod 1 have a first included angle, the outer wall of the first connecting part 150 is aligned with the outer wall of the first mounting part 5. This arrangement makes the telescopic leg 2a more compact and aesthetically pleasing when retracted.

[0527] In some implementations of this technical solution embodiment, refer to Figure 19 After the first support member 100 is housed in the second support member 200, at least three legs 2 can be folded together to form a first columnar structure.

[0528] For example, the first columnar structure is handheld, allowing the power-consuming unit 3 to be used in a handheld state.

[0529] In some implementations of this technical solution embodiment, refer to Figure 19 The first mounting part 5 has a second columnar structure. After the first support member 100 is housed in the second support member 200, the outer wall of the first columnar structure is aligned with the outer wall of the second columnar structure. The advantage of this arrangement is that the structure is more compact and aesthetically pleasing after the telescopic leg 2a is housed.

[0530] In some implementations of this technical solution, the outer wall of the edging 222 is aligned with the outer side wall of the second body 210; when the telescopic leg 2a is at its shortest length, the first connecting part 150 abuts against the edging 222. The advantage of this arrangement is that the structure is more compact and aesthetically pleasing after the telescopic leg 2a is retracted.

[0531] In some implementations of this technical solution embodiment, refer to Figure 1-6The multi-leg bracket, including models 18-24, also includes a first mounting part 5 and at least one first connecting rod 7. The first mounting part 5 is slidable relative to the support rod 1. The first support member 100 is slidable relative to the first sliding groove 201 and can be positioned in the first sliding groove 201. The second support member 200 is provided with a first clearance opening 2010 communicating with the first sliding groove 201. At least one first connecting rod 7 corresponds to at least one telescopic leg 2a. The first end of the first connecting rod 7 is rotatably connected to the first support member 100 of the telescopic leg 2a through the first clearance opening 2010, and the second end of the first connecting rod 7 is rotatably connected to the support rod 1. When the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to avoid the first connecting rod 7. During the sliding process of the first mounting part 5 along the support rod 1, the angle between the telescopic leg 2a and the support rod 1 changes. The advantage of this arrangement is that the first link 7 is rotatably connected to the first support member 100, making the structure of the multi-leg bracket more compact. Furthermore, the setting of the first clearance opening 2010 ensures that the first link 7 does not affect the sliding of the first support member 100 relative to the second support member 200.

[0532] For example, the first end of the first link 7 is a rotating shaft, and the corresponding connection of the first support member is provided with a rotating hole; or, the first end of the first link 7 is a rotating hole, and the corresponding connection of the first support member is provided with a rotating shaft.

[0533] For example, the second end of the first connecting rod 7 is a rotating shaft, and the corresponding connection of the support rod is a rotating hole; or the second end of the first connecting rod 7 is a rotating hole, and the corresponding connection of the support rod is a rotating shaft.

[0534] For example, the first support member 100 is slidable relative to the first sliding groove 201, which can be achieved by the first support member 100 slidingly engaging with the first sliding groove 201, or by the first support member 100 slidingly engaging with the second sliding groove 203.

[0535] For example, during the extension and retraction of the telescopic outrigger, the first end of the first link 7 is always located in the first sliding groove.

[0536] In some implementations of this technical solution embodiment, refer to Figure 18-24 The telescopic support leg 2a can be retracted into the support rod 1. After the telescopic support leg 2a is retracted into the support rod 1, the first connecting rod 7 is located between the telescopic support leg 2a and the support rod 1. The advantage of this arrangement is that it makes the structure of the multi-leg bracket more compact.

[0537] For example, the telescopic leg 2a has a second receiving space 2017. After the telescopic leg 2a is retracted into the support rod 1, the first connecting rod 7 is also retracted into the second receiving space 2017. More specifically, when the first support member 100 of the telescopic leg 2a is retracted into the corresponding second support member 200, and the telescopic leg 2a is retracted into the support rod 1, the first connecting rod 7 is retracted into the second receiving space 2017 via the first clearance opening 2010.

[0538] In some implementations of this technical solution embodiment, refer to Figure 22 When the telescopic support leg 2a is at its shortest, the second support member 200 abuts against the first connecting part 150.

[0539] In some implementations of this technical solution embodiment, refer to Figure 23 The sliding direction perpendicular to the first support member 100 has a first projection plane, and the projection of the first sliding part 140 on the first projection plane encompasses the projection of the first main body 130 on the first projection plane; the first end of the first connecting rod 7 is rotatably connected to the first sliding part 140. The advantage of this arrangement is that the first connecting rod 7 is connected to the "thicker" first sliding part 140, making the telescopic leg 2a less prone to damage and making the structure of the multi-leg bracket more compact.

[0540] In some implementations of this technical solution embodiment, refer to Figure 23 The first sliding part 140 is provided with a first rotating cavity 107, and a first rotating shaft 160 is provided inside the first rotating cavity 107. The first end of the first connecting rod 7 has a first rotating connector 7a, which is rotatably engaged with the first rotating shaft 160. The projection of the first sliding part 140 on the first projection plane encompasses the projection of the first rotating connector 7a on the first projection plane, the projection of the first sliding part 140 on the first projection plane encompasses the projection of the first rotating shaft 160 on the first projection plane, and the projection of the first sliding part 140 on the first projection plane encompasses the projection of the first rotating cavity 107 on the first projection plane. The advantage of this arrangement is that it makes the structure of the multi-legged bracket more compact.

[0541] For example, the second end of the first connecting rod 7 has a second rotating connector 7b, the support rod 1 has a second rotating cavity 1001, the second rotating cavity 1001 is provided with a second rotating shaft 1c, and the second rotating connector 7b is rotatably engaged with the second rotating shaft 1c.

[0542] In some implementations of this technical solution, the multi-leg bracket further includes at least one first link 7, each of which corresponds to at least one telescopic leg 2a. The first end of the first link 7 is fixedly connected to the first support member 100 via a first clearance opening 2010, and the second end of the first link 7 is fixedly connected to the support rod 1. When the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to avoid the first link 7.

[0543] For example, the telescopic outrigger 2a is connected to the support rod 1 only through the first link 7.

[0544] For example, the telescopic outrigger 2a is directly connected to the support rod 1, or the telescopic outrigger 2a is connected to the support rod 1 through an intermediate component.

[0545] In some implementations of this technical solution embodiment, refer to Figure 5 , 12 The multi-leg bracket also includes at least one first link 7, each of which corresponds to at least one telescopic leg 2a. The first end of the first link 7 is connected to the first support member 100 via a first clearance opening 2010, and the second end of the first link 7 is connected to the support rod 1. The first support member 100 is connected to the support rod 1. When the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to avoid the first link 7.

[0546] For example, the first connecting rod 7, the support rod 1, and the telescopic leg 2a are all directly connected to each other (movable connection or fixed connection), which can form a stable triangular structure to support the main electrical unit 3.

[0547] For example, the first link 7 is fixed relative to the support rod 1, and the first link 7 is fixed relative to the first support member 100.

[0548] In some implementations of this technical solution, the first support member 100 is circumferentially fixed relative to the second support member 200, including but not limited to any of the following situations, or a combination of the following situations;

[0549] 1. The first support member 100 is circumferentially fixed to the first sliding groove 201.

[0550] 2. The first support member 100 is circumferentially fixed to the second sliding groove 203.

[0551] In some implementations of this technical solution, the first support member 100 is slidable relative to the second support member 200, including any one of the following situations, or a combination of the following situations:

[0552] 1. The second support member 200 is provided with a first sliding groove 201, and the first support member 100 is slidably installed in the first sliding groove 201.

[0553] 2. The second support member 200 is provided with a first sliding groove 201, and the first support member 100 is slidably installed in the second sliding groove 203.

[0554] In some implementations of this technical solution embodiment, refer to Figure 5 , 22 The first support member 100 is provided with a first limiting wall 102, and the second positioning member 220 is provided with a second limiting wall 202. When the length of the telescopic leg 2a is the longest, the first limiting wall 102 and the second limiting wall 202 abut against each other. And / or, the first support member 100 is provided with a third limiting wall 104, and the second positioning member 220 is provided with a fourth limiting wall 206. When the length of the telescopic leg 2a is the shortest, the third limiting wall 104 and the fourth limiting wall 206 abut against each other.

[0555] For example, the first limiting wall 102 can be provided at any part of the first support member 100. For instance, the first limiting wall 102 can be located on a protrusion protruding from the first body 130. Specifically, the first limiting wall 102 is close to the second end of the first support member 100.

[0556] For example, the third limiting wall 104 can be provided at any part of the first support member 100. For instance, the third limiting wall 104 can be located on a protrusion protruding from the first body 130. Specifically, the third limiting wall 104 is close to the first end of the first support member 100.

[0557] For example, the second limiting wall 202 is close to the first end of the second support member 200, and the fourth limiting wall 206 is close to the first end of the second support member 200.

[0558] In some implementations of this technical solution embodiment, refer to Figure 18 The second support member 200 is provided with a second sliding groove 203; the second sliding groove 203 has a third stretching surface 203a and a fourth stretching surface 203b with opposite extension directions; the third stretching surface 203a and the fourth stretching surface 203b are used to restrict the first support member 100 within the second sliding groove 203 so that the first support member 100 is slidable relative to the second support member 200.

[0559] For example, the second opening 204 of the second positioning member 220 extends through the fourth stretching surface 203b.

[0560] In some implementations of this technical solution embodiment, refer to Figure 9 , 15The first support member 100 has a first damping protrusion 110, which makes damping contact with the second support member 200 so that the first support member 100 can be positioned on the second support member 200 when the telescopic leg 2a is in the supported state.

[0561] In some implementations of this technical solution embodiment, refer to Figure 9 , 15 The first support member 100 includes a first body 130 and a first damping protrusion 110, with the first damping protrusion 110 disposed on the first body 130; the second support member 200 includes a second body 210, with the first body 130 sleeved on the second body 210, and the first damping protrusion 110 making damping contact with the second body 210 so that the first support member 100 is dampingly slidably mounted on the second support member 200.

[0562] In some implementations of this technical solution embodiment, refer to Figure 9 , 15 The first support member 100 is provided with a first deformation opening 101 and a first cantilever 120 formed by extending from the edge of the first deformation opening 101. A first damping protrusion 110 protrudes from the first cantilever 120. The first cantilever 120 is configured to apply an elastic force to the first damping protrusion 110 so that the first damping protrusion 110 makes damping contact with the second support member 200. The first deformation opening 101 serves as the deformation space of the first cantilever 120.

[0563] In some implementations of this technical solution embodiment, refer to Figure 9 , 15 The first damping protrusion 110 makes damping contact with the first sliding groove 201 so that the first support 100 can be positioned on the second support 200.

[0564] In some implementations of this technical solution embodiment, refer to Figure 11 , 12 The first sliding groove 201 is provided with a second limiting part 2019, and the second positioning member 220 is provided with a first limiting part 223. The second positioning member 220 can be slidably inserted into the first sliding groove 201. After the second positioning member 220 is inserted into the first sliding groove 201, the first limiting part 223 and the second limiting part 2019 cooperate to restrict the second positioning member 220 within the first sliding groove 201. The second positioning member 220 allows the first support member 100 to be slidably sleeved on the second support member 200, and / or, the second positioning member 220 allows the first support member 100 to be positioned on the second support member 200. The advantage of this arrangement is that, on the one hand, the second positioning member 220 is easy to install, and on the other hand, it prevents the second positioning member 220 from falling off when the first support member 100 slides relative to the second support member 200.

[0565] For example, the second limiting part 2019 is a groove, and the first limiting part 223 is a protrusion. The first limiting part 223 is provided with a first sliding surface 209. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides past the second body 210. Alternatively, the first limiting part 223 is a groove, the second limiting part 2019 is a protrusion, and the second limiting part 2019 is provided with a second sliding surface. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides past the second positioning member 220. The advantage of this arrangement is that it makes the second positioning member 220 easy to install.

[0566] For example, the second positioning member 220 is detachably installed on the inner wall of the first sliding groove 201. The second positioning member 220 is a thin sheet with a through second opening 204. The second positioning member 220 can be detached from the first sliding groove 201 by squeezing it. When the second positioning member 220 is squeezed, the second opening 204 is deformed.

[0567] For example, the second positioning member 220 is a cylindrical shape adapted to the first sliding groove 201, and the second opening 204 extends from one end of the second positioning member 220 to the other end.

[0568] For example, the second opening 204 extends along the extension direction of the first sliding groove 201.

[0569] For example, the position of the second opening 204 corresponds to the first clearance opening 2010 of the first sliding groove 201.

[0570] In some implementations of this technical solution embodiment, refer to Figure 6 , 24 The multi-leg bracket also includes a first mounting part 5 and at least one first connecting rod 7, with each first connecting rod 7 corresponding to at least one telescopic leg 2a. The first mounting part 5 is slidably mounted on the support rod 1. The telescopic leg 2a is rotatably connected to the first mounting part 5. The support rod 1 includes a support body 1a and a connecting column 1b. The support body 1a has a connecting groove 1002, and the connecting column 1b is inserted into the connecting groove 1002. One end of the first connecting rod 7 is rotatably connected to the telescopic leg 2a, and the other end is rotatably connected to the connecting column 1b. During the sliding of the first mounting part 5 relative to the support rod 1, the angle of the telescopic leg 2a relative to the support rod 1 changes. Inserting the connecting column 1b of the support rod 1 into the connecting groove 1002 makes the structure of the multi-leg bracket more compact.

[0571] For example, the multi-leg bracket also includes a first fastener 1c for fastening the connecting post 1b to the support body 1a. The first fastener 1c passes radially through the outer wall of the support body and is fastened to the connecting post 1b in the connecting groove 1002.

[0572] For example, the connecting post 1b is engaged with the connecting groove 1002 so that the connecting post 1b is mounted on the support body 1a.

[0573] For example, the connecting post 1b is interference-fitted with the connecting groove 1002 so that the connecting post 1b is mounted on the support body 1a.

[0574] In some implementations of this technical solution, refer to Figure 6 , 24 The second support member 200 of the telescopic support leg 2a also includes a foot pad 240, which is installed at one end of the second support member. When the multi-leg bracket is supported on a support surface, the foot pad 240 contacts the support surface.

[0575] For example, the foot pad 240 is detachably mounted to the second body of the second support 200.

[0576] For example, foot pad 240 is made of soft materials such as rubber and plastic.

[0577] For example, the foot pad 240 includes a mounting member 241 and an anti-slip sleeve 242. The mounting member 241 is detachably mounted to the second body of the second support member 200, and the mounting member 241 facilitates the installation of the anti-slip sleeve 242, which covers the mounting member 241. For example, the mounting member 241 can be fastened to the second body by fasteners.

[0578] In some other implementations of this technical solution, refer to Figure 3 The second support member 200 of the telescopic outrigger 2a is rotatably connected to the first mounting part 5, and the first connecting rod 7 is rotatably connected to the second support member 200. When the first mounting part 5 slides relative to the support rod 1, the angle between the telescopic outrigger 2a and the support rod 1 changes. For example, when the multi-leg bracket is supported on a support surface, the first support member 100 extends from the second support member 200 and contacts the support surface.

[0579] In some implementations of this technical solution embodiment, refer to Figures 26 to 26h or refer to Figures 83 to 90 The first connecting part 150 protrudes from the first main body 130. The advantage of this arrangement is that it enhances the structural strength of the rotatable connection between the first support member 100 and the first mounting part 5.

[0580] For example, the first connecting portion 150 has a third limiting wall 132a. When the length of the telescopic leg 2a is at its shortest, the second support member 200 abuts against the third limiting wall 132a, and the third limiting wall 132a is provided in the first connecting portion 150 to make the structure of the telescopic leg 2a more compact.

[0581] For example, the first main body 130 is provided with a fifth limiting wall 105, and when the length of the telescopic leg 2a is at its shortest, the second support member 200 abuts against the fifth limiting wall 105. The advantage of this arrangement is that it avoids the second support member 200 being excessively retracted into the first support member 100.

[0582] For example, the third limiting wall 132a is located outside the first support member 100, and the fifth limiting wall 105 is located inside the first support member 100. The advantage of this arrangement is that it makes the structure more stable when the telescopic leg 2a is in its shortest state.

[0583] For example, the fifth limiting wall 105 includes two fifth limiting sub-walls 105a, and the third limiting wall 132a is located between the two fifth limiting sub-walls 105a. The advantage of this arrangement is that it makes the structure of the telescopic leg 2a more stable when it is in its shortest state.

[0584] For example, the second support member 200 is provided with a second sliding groove 203, and the first main body 130 is slidable relative to the second sliding groove 203; the first main body 130 has a third sliding body 130a and a fourth sliding body 130b, the second sliding groove 203 includes a third sliding sub-groove 2031 and a fourth sliding sub-groove 2032, the third sliding body 130a and the fourth sliding body 130b are respectively adapted to the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032, the third sliding body 130a and the fourth sliding body 130b are respectively slidably installed in the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032, and two fifth limiting sub-walls 105a are respectively close to the third sliding body 130a and the fourth sliding body 130b. The advantages of this design are that, on the one hand, the structure of the telescopic support 2a is more stable when it is in its shortest state; on the other hand, the structure of the telescopic support 2a is more compact; and furthermore, the design of the third sliding sub-slot 2031 and the fourth sliding sub-slot 2032 makes the extension and retraction of the telescopic support 2a more stable.

[0585] For example, two first positioning protrusions 131 are respectively provided on the third slider 130a and the fourth slider 130b, and two second positioning protrusions 132 are respectively provided on the third slider 130a and the fourth slider 130b.

[0586] For example, the third slider 130a and the fourth slider 130b are located on opposite sides of the first body 130. This arrangement has several advantages: firstly, it makes the telescopic leg 2a more stable when in its shortest state; secondly, it makes the structure of the telescopic leg 2a more compact; and thirdly, the location of the third slider 130a and the fourth slider 130b on opposite sides of the first body 130 makes the extension and retraction of the telescopic leg 2a more stable.

[0587] For example, the third sliding sub-slot 2031 and the fourth sliding sub-slot 2032 are located on opposite sides of the second sliding slot 203, respectively. The third sliding sub-slot 2031 is a slot with an opening, and the fourth sliding sub-slot 2032 is a slot with an opening.

[0588] For example, the second support member 200 has a first shell 251 and a second shell 252, a third sliding sub-groove 2031 located in the space surrounded by the first shell 251, and a fourth sliding sub-groove 2032 located in the space surrounded by the second shell 252. When the length of the telescopic leg is at its shortest, the two fifth limiting sub-walls 105a abut against the ends of the first shell 251 and the second shell 252, respectively.

[0589] The advantages of this design are twofold: firstly, it makes the structure of the telescopic leg 2a more stable when it is in its shortest state; secondly, the first casing 251 accommodates the third sliding sub-groove 2031 and abuts against the fifth limiting sub-wall 105a, and the second casing 252 accommodates the fourth sliding sub-groove 2032 and abuts against the fifth limiting sub-wall 105a, thereby making the structure of the telescopic leg 2a more compact.

[0590] For example, the first casing 251 has a first sealing plate 251a, which is used to partially close the opening of the third sliding sub-groove 2031 and to further seal the third sliding body 130a within the third sliding sub-groove 2031.

[0591] For example, the second casing 252 has a second sealing plate 252a for partially closing the fourth sliding sub-groove 2032 and for sealing the fourth sliding body 130b in the fourth sliding sub-groove 2032.

[0592] For example, when the telescopic leg is at its shortest length, the two fifth limiting sub-walls 105a abut against the ends of the first sealing plate 251a and the second sealing plate 252a, respectively.

[0593] For example, the first sealing plate 251a and the second sealing plate 252a are located on opposite sides of the first clearance opening 2010.

[0594] For example, when the telescopic leg 2a is at its shortest length, the first main body 130 is housed within the second support member 200, and the fifth limiting wall 105 is also housed within the second support member 200. This arrangement makes the structure of the telescopic leg 2a more compact.

[0595] For example, the three telescopic legs 2a can be retracted to form a first columnar structure. After the three telescopic legs 2a are retracted to form the first columnar structure, the first connecting rod 7 is retracted into the second receiving space 2017 of the telescopic legs 2a through the first clearance opening 2010. The advantage of this arrangement is that after the telescopic legs 2a are retracted into the support rod 1, the structure of the multi-leg bracket is more compact.

[0596] In some implementations of this technical solution, the first support member 100 includes a first main body 130 and a first connecting portion 150 disposed on the first main body 130. The first main body 130 is sleeved on the second support member 200. The first main body 130 is slidable relative to the second support member 200 to change the length of the telescopic leg 2a. The first main body 130 can be positioned on the second support member 200 so that the telescopic leg 2a can support the support rod 1. The multi-leg bracket also includes a first mounting portion 5 disposed on the support rod 1. The first connecting portion 150 is rotatably mounted on the first mounting portion 5 so that the angle between the telescopic leg 2a and the support rod 1 is adjustable. The first connecting portion 150 protrudes from the first main body 130. The advantage of this arrangement is that it enhances the structural strength of the rotatable connection between the first support member 100 and the first mounting portion 5.

[0597] In some implementations of this technical solution, the first support member 100 has a first connecting portion 150, which is rotatably mounted on the first mounting portion 5 so that the angle between the telescopic leg 2a and the support rod 1 is adjustable. The first connecting portion 150 of the first support member 100 has a third limiting wall 132a, and when the length of the telescopic leg 2a is at its shortest, the second support member 200 abuts against the third limiting wall 132a. The advantage of this arrangement is that, on the one hand, it avoids the first support member 100 being excessively retracted into the second support member 200, and on the other hand, placing the third limiting wall 132a on the first connecting wall makes the structure of the telescopic leg 2a more compact.

[0598] In some implementations of this technical solution, all three legs 2 can be housed in the support rod 1. After all three legs 2 are housed in the support rod 1, the first mounting part 5 and the three legs 2 together form a columnar structure.

[0599] For example, the first support member 100 is provided with a fifth limiting wall 105, and when the length of the telescopic leg 2a is the shortest, the second support member 200 abuts against the fifth limiting wall 105.

[0600] For example, the fifth limiting wall 105 is located inside the first support member 100. The advantage of this arrangement is that, on the one hand, it avoids the first support member 100 being excessively retracted into the second support member 200, and on the other hand, it makes the structure of the telescopic leg 2a more compact.

[0601] For example, the second support member 200 is provided with a second sliding groove 203, and the first main body 130 is slidable relative to the second sliding groove 203; the first main body 130 has a third sliding body 130a and a fourth sliding body 130b, the second sliding groove 203 includes a third sliding sub-groove 2031 and a fourth sliding sub-groove 2032, the third sliding body 130a and the fourth sliding body 130b are respectively adapted to the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032, and the third sliding body 130a and the fourth sliding body 130b are respectively slidably installed in the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032 adapted to each other, and the fifth limiting wall 105 includes two fifth limiting sub-walls 105a, the two fifth limiting sub-walls 105a are respectively close to the third sliding body 130a and the fourth sliding body 130b. The advantages of this design are that, on the one hand, the structure of the telescopic support 2a is more stable when it is in its shortest state; on the other hand, the two fifth limiting sub-walls 105a are close to the third sliding body 130a and the fourth sliding body 130b respectively, which makes the structure of the telescopic support 2a more compact; and on the other hand, the design of the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032 makes the extension and retraction of the telescopic support 2a more stable.

[0602] For example, the first support member 100 is provided with a first reinforcing rib 261, and a fifth limiting wall 105 is provided on the first reinforcing rib 261. On the one hand, the first reinforcing rib 261 is used to increase the structural strength of the second support member 200. On the other hand, providing the fifth limiting wall 105 on the first reinforcing rib 261 makes the structure of the telescopic leg 2a more compact.

[0603] For example, when the telescopic leg 2a is at its shortest length, the first main body 130 is housed within the second support member 200, and the first reinforcing rib 261 is also housed within the second support member 200. The advantage of this arrangement is that the telescopic leg 2a has a more compact structure when folded.

[0604] For example, at least three legs are telescopic legs 2a; the multi-leg bracket also includes at least three first connecting rods 7; the first mounting part 5 is slidable relative to the support rod 1; at least three first connecting rods 7 correspond to at least three telescopic legs 2a respectively; the second support member 200 is provided with a first sliding groove 201; the first body 130 of the first support member 100 is sleeved in the first sliding groove 201; the first support member 100 is slidable relative to the first sliding groove 201; the second support member 200 is provided with a first clearance opening 2010 communicating with the first sliding groove 201; the first end of the first connecting rod 7 is rotatably connected to the first support member 100 of the corresponding telescopic leg 2a; the second end of the first connecting rod 7 is rotatably connected to the support rod 1. When the first main body 130 of the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to clear the corresponding first connecting rod 7; during the sliding process of the first mounting part 5 along the support rod 1, the telescopic leg 2a opens or retracts relative to the support rod 1; after the first support member 100 of each telescopic leg 2a is retracted into the corresponding second support member 200, at least three telescopic legs 2a can be retracted into the support rod 1 to form a first columnar structure. During the process of the three telescopic legs 2a being retracted to form the first columnar structure, the first connecting rod 7 is retracted into the second receiving space 2017 of the telescopic leg 2a through the first clearance opening 2010. On the one hand, the first connecting rod 7 is rotatably connected to the first support member 100 of the telescopic leg 2a, making the structure of the telescopic leg 2a more compact. On the other hand, the second support member 200 is provided with a first clearance opening 2010 to avoid the first connecting rod 7, which prevents the first connecting rod 7 from obstructing the extension and retraction of the telescopic leg 2a. Furthermore, the telescopic leg 2a has a second accommodating space 2017 to accommodate the first connecting rod 7 after being stored, making the structure of the telescopic leg 2a compact and occupying a small volume after being stored.

[0605] In some implementations of this technical solution, the first support member 100 includes a first body 130, which has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first body 130 extends out from the second support member 200. When the telescopic leg 2a is at its shortest length, the first end of the first body 130 is retracted into the second support member 200. The advantage of this arrangement is that the structure is more compact when the telescopic leg 2a is in its retracted state.

[0606] For example, the first support member 100 also includes a first connecting part 150 disposed on the first body 130. The first connecting part 150 is disposed at the first end of the first body 130 and is rotatably mounted on the first mounting part 5 so that the angle between the telescopic leg 2a and the support rod 1 is adjustable.

[0607] For example, when the telescopic leg 2a is at its shortest length, the first connecting part 150 abuts against the second support member 200. The advantage of this arrangement is that the first connecting part 150 is used both for rotatable connection with the first mounting part 5 and for abutting against the second support member 200, making the structure of the telescopic leg 2a compact.

[0608] In some implementations of this technical solution, the first support member 100 is slidably sleeved on the second support member 200. The second support member 200 has a first sliding sub-groove 201d and a second sliding sub-groove 201e. The first support member 100 has a first sliding body 141 and a second sliding body 142 respectively adapted to the first sliding sub-groove 201d and the second sliding sub-groove 201e. The first sliding body 141 is slidably installed in the first sliding sub-groove 201d, and the second sliding body 142 is slidably installed in the second sliding sub-groove 201e. The first support member 100 can be positioned on the second support member 200 so that the telescopic support leg 2a can support the support rod 1. The advantage of setting the first sliding sub-groove 201d and the second sliding sub-groove 201e is that it makes the first support member 100 more stable when sliding relative to the second support member 200.

[0609] For example, the first slider 141 and the second slider 142 are located on opposite sides of the first support 100. The advantage of this arrangement is that it makes the structure of the telescopic leg 2a more compact.

[0610] For example, the second support member 200 has a third sliding sub-slot 2031 and a fourth sliding sub-slot 2032, and the first support member 100 has a third sliding body 130a and a fourth sliding body 130b respectively adapted to the third sliding sub-slot 2031 and the fourth sliding sub-slot 2032. The third sliding body 130a is slidably mounted in the third sliding sub-slot 2031, and the fourth sliding body 130b is slidably mounted in the fourth sliding sub-slot 2032. The advantage of this arrangement is that it makes the first support member 100 more stable when sliding relative to the second support member 200.

[0611] For example, the third slider 130a and the fourth slider 130b are located on opposite sides of the first support 100. The advantage of this arrangement is that it makes the structure of the telescopic leg 2a more compact.

[0612] For example, the first sliding sub-slot 201d is coaxial with the third sliding sub-slot 2031, the second sliding sub-slot 201e is coaxial with the fourth sliding sub-slot 2032, the cross-section of the third sliding sub-slot 2031 is smaller than the cross-section of the first sliding sub-slot 201d, the cross-section of the fourth sliding sub-slot 2032 is smaller than the cross-section of the second sliding sub-slot 201e, and the first support member 100 is non-detachably sleeved on the second support member 200.

[0613] For example, the multi-leg bracket also includes a first mounting portion 5 and at least one first connecting rod 7; the first mounting portion 5 is slidable relative to the support rod 1; at least one first connecting rod 7 corresponds to at least one telescopic leg 2a; the second support member 200 is provided with a first clearance opening 2010, which is located between a first sliding sub-slot 201d and a second sliding sub-slot 201e; the first end of the first connecting rod 7 is rotatably connected to the first support member 100 of the corresponding telescopic leg 2a, and the second end of the first connecting rod 7 is rotatably connected to the support rod 1; when the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to clear the corresponding first connecting rod 7; during the sliding of the first mounting portion 5 along the support rod 1, the telescopic leg 2a is retracted or opened relative to the support rod 1. Positioning the first clearance opening 2010 between the first sliding sub-slot 201d and the second sliding sub-slot 201e makes the structure of the telescopic leg 2a more compact.

[0614] For example, the first sliding sub-slot 201d is formed by being surrounded by the first housing 251, the second sliding sub-slot 201e is formed by being surrounded by the second housing 252, and the first clearance opening 2010 is located between the first housing 251 and the second housing 252. The advantage of this arrangement is that it makes the structure of the telescopic leg 2a more compact.

[0615] For example, the first support member 100 has a first guide wall 271 and a second guide wall 272. The first guide wall 271 is close to or adjacent to the first casing 251, and the second guide wall 272 is close to or adjacent to the second casing 252. When the first support member 100 slides relative to the second support member 200, the first clearance opening 2010 serves as an opening to avoid the first guide wall 271 and the second guide wall 272. The advantage of providing the first guide wall 271 and the second guide wall 272 is that it makes the first support member 100 more stable when sliding relative to the second support member 200.

[0616] For example, the first guide wall 271 is close to or against the first sealing plate 251a, and the second guide wall 272 is close to or against the second sealing plate 252a.

[0617] For example, the first support member 100 has a second reinforcing rib 262, a first guide wall 271 located at the end of the second reinforcing rib 262, and a first clearance opening 2010 serving as an opening to clear the second reinforcing rib 262. The advantage of this arrangement is that, on the one hand, the second reinforcing rib 262 strengthens the first support member 100; on the other hand, the first guide wall 271 and the second guide wall 272 of the second reinforcing rib 262 also make the sliding of the first support member 100 relative to the second support member 200 more stable.

[0618] For example, the second support member 200 is provided with a first clearance opening 2010, which is located between the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032. The advantage of this arrangement is that it makes the structure of the telescopic support leg 2a more compact.

[0619] For example, the first support member 100 has at least one second reinforcing rib 262 and at least one third reinforcing rib 263, each second reinforcing rib 262 being connected to at least one third reinforcing rib 263. When the first support member 100 slides relative to the second support member 200, the first clearance opening 2010 serves as an opening to avoid the second reinforcing rib 262 and the third reinforcing rib 263. The angle between the extending direction of the second reinforcing rib and the extending direction of the first clearance opening 2010 is 75°-105°, and the angle between the extending direction of the third reinforcing rib and the extending direction of the first clearance opening 2010 is 0-15°. The advantage of providing the second reinforcing rib 262 and the third reinforcing rib 263 is that it further improves the structural strength of the first support member 100.

[0620] For example, the extension direction of the second reinforcing rib 262 is perpendicular to the extension direction of the first clearance opening 2010, and the extension direction of the third reinforcing rib 263 is parallel to the extension direction of the first clearance opening 2010.

[0621] In some implementations of this technical solution, the first support member 100 is slidably sleeved on the second support member 200, and the first support member 100 can be positioned on the second support member 200 so that the telescopic support leg 2a can support the support rod 1; the second support member 200 is provided with a first clearance opening 2010, and the first support member 100 has at least one second reinforcing rib 262. When the first support member 100 slides relative to the second support member 200, the first clearance opening 2010 serves as an opening to avoid the first reinforcing rib 262.

[0622] For example, the angle between the extending direction of the second reinforcing rib 262 and the extending direction of the first clearance opening 2010 is 75°-105°. For instance, the extending direction of the second reinforcing rib 262 is perpendicular to the direction of the first clearance opening 2010.

[0623] For example, the first support member 100 has at least one third reinforcing rib 263, and when the first support member 100 slides relative to the second support member 200, the first clearance opening 2010 serves as an opening to avoid the third reinforcing rib 263.

[0624] For example, the angle between the extending direction of the third reinforcing rib 263 and the extending direction of the first clearance opening 2010 is 0-15°. For instance, the extending direction of the third reinforcing rib 263 is parallel to the extending direction of the first clearance opening 2010.

[0625] For example, each second reinforcing rib 262 is connected to at least one third reinforcing rib 263.

[0626] For example, the first support member 100 has at least one first guide wall 271 and at least one second guide wall 272. The first guide wall 271 is close to or adjacent to the first side wall 2010a of the first clearance opening 2010, and the second guide wall 272 is close to or adjacent to the second side wall 2010b of the second clearance opening. The first side wall 2010a and the second side wall 2010b are respectively located on opposite sides of the first clearance opening 2010. When the first support member 100 slides relative to the second support member 200, the first clearance opening 2010 serves as an opening to avoid the first guide wall 271 and the second guide wall 272.

[0627] For example, a first sidewall 2010b is provided on a first sealing plate 251a, and a second sidewall 2010b is provided on a second sealing plate 252a.

[0628] For example, the first guide wall 271 is located at the end of the second reinforcing rib 262, and the second guide wall 272 is located at the end of the second reinforcing rib 262.

[0629] For example, at least three legs are telescopic legs 2a, and the multi-leg bracket also includes a first mounting part 5 and at least three first connecting rods 7; the first mounting part 5 is slidable relative to the support rod 1; the at least three first connecting rods 7 correspond to at least three telescopic legs 2a respectively, the first end of the first connecting rod 7 is rotatably connected to the first support member 100 of the corresponding telescopic leg 2a, and the second end of the first connecting rod 7 is rotatably connected to the support rod 1. When the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to clearance the corresponding first connecting rod 7; during the sliding of the first mounting part 5 along the support rod 1, the telescopic legs 2a are retracted or opened relative to the support rod 1; the three telescopic legs 2a can be retracted to form a first columnar structure, and after the three telescopic legs 2a are retracted to form the first columnar structure, the first connecting rod 7 is retracted into the second receiving space 2017 of the telescopic leg 2a through the second clearance opening.

[0630] In some implementations of this technical solution embodiment, this technical solution embodiment also proposes a multi-leg bracket, which includes a support rod 1 and at least three legs. The at least three legs are used to support the support rod 1, and the support rod 1 is used to support the electrical main body. The feature is that at least one of the at least three legs is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The first support member 100 is slidably sleeved on the second support member 200. The first support member 100 can be positioned on the second support member 200 so that the telescopic leg 2a can support the support rod 1. The second support member 200 is provided with a first clearance. The opening 2010, the first support member 100 has at least one first guide wall 271 and at least one second guide wall 272, the first guide wall 271 is close to or adjacent to the first side wall 2010a of the first clearance opening 2010, the second guide wall 272 is close to or adjacent to the second side wall 2010b of the second clearance opening, the first side wall 2010a and the second side wall 2010b are respectively located on opposite sides of the first clearance opening 2010; when the first support member 100 slides relative to the second support member 200, the first clearance opening 2010 serves as an opening to avoid the first guide wall 271 and the second guide wall 272.

[0631] For example, at least three legs are telescopic legs 2a, and the multi-leg bracket also includes a first mounting part 5 and at least three first connecting rods 7; the first mounting part 5 is slidable relative to the support rod 1; the at least three first connecting rods 7 correspond to at least three telescopic legs 2a respectively, the first end of the first connecting rod 7 is rotatably connected to the first support member 100 of the corresponding telescopic leg 2a, and the second end of the first connecting rod 7 is rotatably connected to the support rod 1. When the first support member 100 slides relative to the second support member 200 of the telescopic leg 2a, the first clearance opening 2010 serves as an opening to clearance the corresponding first connecting rod 7; during the sliding of the first mounting part 5 along the support rod 1, the telescopic legs 2a are retracted or opened relative to the support rod 1; the three telescopic legs 2a can be retracted to form a first columnar structure, and after the three telescopic legs 2a are retracted to form the first columnar structure, the first connecting rod 7 is accommodated in the second accommodating space 2017 of the telescopic leg 2a through the first clearance opening 2010.

[0632] This technical solution embodiment also proposes a multi-legged support, see reference. Figure 27-48The multi-leg bracket includes a support rod 1 and at least three legs 2. The at least three legs 2 support the support rod 1, and the support rod 1 supports the electrical main body 3. At least one of the at least three legs 2 is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The first support member 100 is sleeved on the second support member 200 and is slidable relative to the second support member 200. The first support member 100 includes a first body 130 and a first positioning member 170 disposed on the first body 130. The first positioning member 170 is provided with a first damping protrusion 110, which makes damping contact with the second support member 200 so that the first support member 100 can be positioned on the second support member 200 when the telescopic leg 2a is in the supported state; the second support member 200 is provided with a first sliding groove 201, the shape of the first positioning member 170 is adapted to the first sliding groove 201, the first positioning member 170 is slidably installed in the first sliding groove 201, and the first positioning member 170 is located between the first body 130 and the second support member 200.

[0633] Understandably, the first positioning element 170 and the first main body 130 constitute the first supporting main body.

[0634] For example, refer to Figure 48 This technical solution embodiment proposes a shooting bracket, including a shooting terminal 3 and a multi-leg bracket. The support rod 1 of the multi-leg bracket is used to support the shooting terminal 3, which can be a mobile phone, tablet, etc.

[0635] For example, the first positioning element 170 is integrally disposed on the first body 130, or the first positioning element 170 is detachably disposed on the first body 130.

[0636] For example, the first positioning element 170 is fixedly disposed on the first body 130.

[0637] For example, the first positioning member 170 serves as a first sliding part 140 that slides in conjunction with the first sliding groove 201, so as to enable the first support member 100 to be slidably mounted on the second support member 200.

[0638] Understandably, the first support member 100 can be positioned on the second support member 200 via the first damping protrusion 110.

[0639] For example, the first positioning member 170 serves as a first sliding part 140 that slides in conjunction with the first sliding groove 201, and the first sliding part 140 is circumferentially fixed to the first sliding groove 201.

[0640] In some implementations of this technical solution embodiment, refer to Figure 36The first positioning member 170 has a first base surface 108, and a first damping protrusion 110 is located on the first base surface 108 and protrudes relative to the first base surface 108. The first base surface 108 is adapted to the inner wall of the first sliding groove 201. The advantage of setting the first base surface 108 is that it is convenient to set the first damping protrusion 110.

[0641] For example, the first base surface 108 is part or all of the outer wall of the first positioning element 170.

[0642] For example, the first base surface 108 is opposite to the first stretching surface 201a. For instance, the cross-section of the first stretching surface 201a is arc-shaped, and the cross-section of the first base surface 108 is also arc-shaped.

[0643] In some implementations of this technical solution embodiment, refer to Figure 36 The first damping protrusion 110 extends in a strip shape.

[0644] For example, the first damping protrusion 110 is generally in the shape of an arc-shaped strip.

[0645] In some implementations of this technical solution embodiment, refer to Figure 36 A second line connects any point at the first end of the first damping protrusion 110 to any point at the second end of the first damping protrusion 110. The first support member 100 extends along the first straight line, and the angle between the second line and the first straight line is 75°-90° (e.g., 75°, 80°, 85°, 90°, etc.). The advantage of this arrangement is that it makes the damping effect of the first damping protrusion 110 better.

[0646] In some implementations of this technical solution embodiment, refer to Figure 36 The length of the second connecting line is 80%-100% of the maximum width of the first sliding groove 201. The first sliding groove 201 has two first sides 201c extending along the sliding direction of the first support member 100. The distance between the two first sides 201c is the maximum width of the first sliding groove 201. The two ends of the first damping protrusion 110 are respectively close to the two first sides 201c. The advantage of this arrangement is that, on the one hand, the first support member 100 is more stable when sliding relative to the second support member 200, and on the other hand, the first support member 100 has a more stable positioning effect relative to the second support member 200.

[0647] For example, the length of the second connecting line is 80%, 85%, 90%, 95%, or 100% of the maximum width of the first sliding groove 201.

[0648] In some implementations of this technical solution embodiment, refer to Figure 36The number of first damping protrusions 110 is two, and the two first damping protrusions 110 are arranged at intervals along the sliding direction of the first support member 100. The advantage of this arrangement is that the first support member 100 has at least two contact points with the second support member 200 along the sliding direction of the first support member 100, making the first support member 100 more stable relative to the second support member 200, and making the first support member 100 less prone to shaking when positioned relative to the second support member 200, or less prone to shaking when the first support member 100 slides relative to the second support member 200.

[0649] In some implementations of this technical solution embodiment, refer to Figure 36 The edge of the first damping protrusion 110 gradually transitions to the first base surface 108. The advantage of this design is that it facilitates the insertion of the first positioning member 170 into the first sliding groove 201.

[0650] It is understandable that the gradual transition between the edge of the first damping protrusion 110 and the first base surface 108 means that the thickness of the edge of the first damping protrusion 110 gradually changes relative to the first base surface 108.

[0651] For example, the edge of the first damping protrusion 110 smoothly transitions to the first base surface 108.

[0652] For example, the edge of the first damping protrusion 110 transitions to the first base surface 108 at an angle.

[0653] In some implementations of this technical solution embodiment, refer to Figure 36 When the first positioning member 170 is located between the first main body 130 and the second support member 200, the first base surface 108 is in contact with the inner wall of the first sliding groove 201. The first positioning member 170 has a second base surface 109, which is in contact with the outer wall of the first main body 130. The first positioning member 170 is provided with a first cavity 1012, which is located on the second base surface 109 and is recessed relative to the second base surface 109. The first cavity 1012 corresponds to the first damping protrusion 110. The advantages of this design are twofold: firstly, it makes it easy for the first positioning member 170 to be installed into the first sliding groove 201; secondly, the first cavity 1012 and the first damping protrusion 110 form a dome-shaped protrusion, and due to the elastic deformation of the dome-shaped protrusion, the first support member 100 and the second support member 200 have a certain damping force; and thirdly, when the first support member 100 and the second support member 200 are subjected to uneven forces (for example, when subjected to forces perpendicular to the sliding direction), the first cavity 1012 serves as the deformation space for the first damping protrusion 110, thus preventing the damping force between the first support member 100 and the second support member 200 from being too large.

[0654] In some implementations of this technical solution embodiment, refer to Figure 36The first positioning element 170 is detachably disposed on the first body 130. The first positioning element 170 is in the shape of a thin sheet and has a first opening 1010. The first positioning element 170 can be inserted into the first body 130 through the first opening 1010. The advantage of this arrangement is that it makes the first positioning element 170 easy to install.

[0655] For example, when installing the first positioning member 170, the first positioning member 170 can be pried open through the first opening 1010 so that the first positioning member 170 can be fitted onto the first body 130. When disassembling the first positioning member 170, the first positioning member 170 can be pried open through the first opening 1010 so that the first positioning member 170 can be removed from the first body 130.

[0656] For example, the first positioning member 170 is a cylindrical shape adapted to the first sliding groove 201, and the first opening 1010 extends from one end of the first positioning member 170 to the other end.

[0657] For example, the first opening 1010 extends in the same direction as the first sliding groove 201.

[0658] In some implementations of this technical solution embodiment, refer to Figure 36 The first positioning member 170 is detachably disposed on the first body 130. When the first support member 100 slides relative to the second support member 200, the first positioning member 170 is fixed relative to the first body 130. The first body 130 is provided with two retaining walls 1011, and the first positioning member 170 is retained between the two retaining walls 1011 so that the first positioning member 170 is fixed relative to the first body 130 when the first support member 100 slides relative to the second support member 200. The advantage of this arrangement is that when the first support member 100 slides relative to the second support member 200, the first positioning member 170 is not easily disengaged from the first body 130.

[0659] For example, two retaining walls 1011 are located on two retaining protrusions 180 respectively, and the two retaining protrusions 180 are respectively protruding from the first body 130, and the two retaining protrusions 180 are spaced apart.

[0660] For example, the first limiting wall 102 is close to the second end of the first support member 100, the second limiting wall 202 is close to the first end of the second support member 200, the third limiting wall 104 is close to the first end of the first support member 100, and the fourth limiting wall 206 is close to the first end of the second support member 200.

[0661] For example, the first limiting wall 102 is located on one of the retaining protrusions 180, and the first limiting wall 102 is opposite to the retaining wall 1011 of the retaining protrusion 180.

[0662] In some implementations of this technical solution embodiment, refer to Figure 36 The first support member 100 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first end of the first support member 100 extends from the second support member 200, and the first damping protrusion 110 is close to or located at the second end of the first support member 100. The advantage of this arrangement is that it allows the telescopic leg 2a to have a longer support length.

[0663] In some implementations of this technical solution embodiment, refer to Figure 39 , 40 The first support member 100 has a first positioning protrusion 131, and the second support member 200 has a second positioning protrusion 221. During the sliding process of the first support member 100 relative to the second support member 200, the first positioning protrusion 131 can abut against or slide past the second positioning protrusion 221. When the first positioning protrusion 131 abuts against the second positioning protrusion 221, the first support member 100 can be positioned relative to the second support member 200 when the telescopic support leg 2a is in the supported state.

[0664] In some implementations of this technical solution, referring to 35, 38, 41, etc., the second support member 200 is provided with a second damping protrusion 230. The second damping protrusion 230 makes damping contact with the first support member 100 so that when the telescopic leg 2a is in the supporting state, the first support member 100 can be positioned on the second support member 200.

[0665] Understandably, the first support member 100 is positioned on the second support member 200 by the second damping protrusion 230.

[0666] In some implementations of this technical solution embodiment, refer to Figure 35 , 38 41, etc., the second support member 200 includes a second main body 210 and a second positioning member 220 disposed on the second main body 210, a second damping protrusion 230 disposed on the second positioning member 220, and a first main body 130 slidably sleeved on the second positioning member 220, with the second damping protrusion 230 in damping contact with the first main body 130. The advantage of this arrangement is that the first support member 100 is slidably installed on the second positioning member 220 and also slidably installed on the first sliding groove 201, improving the stability of the first support member 100 during sliding.

[0667] In other examples, the second damping protrusion 230 and the second positioning protrusion 221 are disposed on the second body 210. For example, the second positioning protrusion 221 is integrally disposed on the second body 210, and the second damping protrusion 230 is integrally disposed on the second body 210.

[0668] In some implementations of this technical solution embodiment, refer to Figures 35-39The second positioning member 220 is disposed between the first body 130 and the second body 210. The second positioning member 220 has a third base surface 2011, and the second damping protrusion 230 is located on the third base surface 2011 and protrudes relative to the third base surface 2011. The third base surface 2011 is adapted to the outer wall of the first body 130. The advantage of this arrangement is that it facilitates the installation of the second damping protrusion 230.

[0669] For example, the third base surface 2011 is part or all of the inner wall of the second positioning element 220.

[0670] For example, the third base surface 2011 is the third tension surface 203a (or, the third base surface 2011 is a part of the third tension surface 203a), and the cross-section of the third base surface 2011 is arc-shaped.

[0671] In some implementations of this technical solution embodiment, refer to Figures 35-39 The third base surface 2011 is attached to the outer wall of the first body 130. The second positioning member 220 has a fourth base surface 2012, which is attached to the inner wall of the second body 210. The third base surface 2011 and the fourth base surface 2012 are opposite to each other. The second positioning member 220 is provided with a second cavity 2013, which is located on the fourth base surface 2012 and recessed relative to the fourth base surface 2012. The second cavity 2013 corresponds to the second damping protrusion 230. On the one hand, it makes it easy for the second positioning member 220 to be installed into the first sliding groove 201. On the other hand, the second cavity 2013 and the second damping protrusion form a dome-shaped protrusion. Due to the elastic deformation of the dome-shaped protrusion, the first support member 100 and the second support member 200 have a certain damping force. Furthermore, when the first support member 100 and the second support member 200 are subjected to uneven forces (for example, when subjected to forces perpendicular to the sliding direction), the second cavity 2013 serves as the deformation space for the second damping protrusion 230, thus preventing the damping force between the first support member 100 and the second support member 200 from being too large.

[0672] It is understandable that the fourth base surface 2012 is in contact with the inner wall of the first sliding groove 201, for example, the fourth base surface 2012 is in contact with the first stretching surface 201a of the first sliding groove 201.

[0673] In some implementations of this technical solution embodiment, refer to Figures 35-39 The second damping protrusion 230 extends in a strip shape, and a third line connects any point at the first end of the second damping protrusion 230 to any point at the second end of the second damping protrusion 230. The first support member 100 extends along the first straight line, and the angle between the third line and the first straight line is 75°-90° (e.g., 75°, 80°, 85°, 90°, etc.). The advantage of this design is that it makes the damping effect of the first damping protrusion 110 better.

[0674] In some implementations of this technical solution embodiment, refer to Figures 35-39 There are two second damping protrusions 230, which are spaced apart along a sliding direction perpendicular to the first support member 100. The second positioning member 220 has a second sliding groove 203 adapted to the first body 130. The first body 130 is slidably mounted on the second sliding groove 203. The second sliding groove 203 has two first side edges 203c along the sliding direction of the first body 130. The distance between the two first side edges 203c is the maximum width of the second sliding groove 203. The two second damping protrusions 230 are located at or near the first side edges 203c. This makes the first support member 100 more stable when sliding relative to the second support member 200, and also makes the first support member 100 have a more stable positioning effect relative to the second support member 200.

[0675] In some implementations of this technical solution embodiment, refer to Figures 35-39 The edge of the first damping protrusion 110 gradually transitions to the third base surface 2011. The advantage of this design is that it facilitates the insertion of the first support member 100 into the first positioning member 170.

[0676] It is understandable that the gradual transition between the edge of the second damping protrusion 230 and the third base surface 2011 means that the thickness of the edge of the second damping protrusion 230 gradually changes relative to the third base surface 2011.

[0677] For example, the edge of the second damping protrusion 230 smoothly transitions to the third base surface 2011.

[0678] For example, the edge of the second damping protrusion 230 transitions to the third base surface 2011 at an angle.

[0679] In some implementations of this technical solution embodiment, refer to Figures 35-39 The second positioning element 220 is in the form of a thin sheet and is detachably disposed on the second main body 210.

[0680] In some implementations of this technical solution embodiment, refer to Figures 35-39 The second support member 200 has a first end and a second end. When the telescopic leg 2a is at its longest length, the first support member 100 extends from the first end of the second support member 200, and the second damping protrusion 230 is close to or located at the first end of the second support member 200.

[0681] In some implementations of this technical solution embodiment, refer to Figures 35-39The first support member 100 has a first damping protrusion 110, which makes damping contact with the second support member 200 so that the first support member 100 can be positioned on the second support member 200 when the telescopic leg 2a is in the supported state. The first support member 100 has a first base surface 108, and the first damping protrusion 110 is located on the first base surface 108 and protrudes relative to the first base surface 108. The first base surface 108 is adapted to the inner wall of the second support member 200. The advantage of providing the first base surface 108 is that it facilitates the installation of the first damping protrusion 110.

[0682] For example, the first base surface 108 is located at the first positioning element 170 of the first support 100, or the first base surface 108 is located at the first body 130 of the first support 100.

[0683] In some implementations of this technical solution embodiment, refer to Figures 35-39 The second support member 200 is provided with a first sliding groove 201, the first support member 100 is slidably sleeved in the first sliding groove 201, the first damping protrusion 110 makes damping contact with the inner wall of the first sliding groove 201, and the first base surface 108 is adapted to the inner wall of the first sliding groove 201.

[0684] In some implementations of this technical solution embodiment, refer to Figures 35-39 The first support member 100 has a second base surface 109, and a first thin wall is formed between the first base surface 108 and the second base surface 109. The first support member 100 is provided with a first cavity 1012, which is located on the second base surface 109 and recessed relative to the second base surface 109. The first cavity 1012 corresponds to the first damping protrusion 110. The advantage of this arrangement is that the first cavity 1012 and the first damping protrusion 110 form a dome-shaped protrusion. Due to the elastic deformation of the dome-shaped protrusion, the first support member 100 and the second support member 200 have a certain damping force. Furthermore, when the first support member 100 and the second support member 200 are subjected to uneven forces (for example, when subjected to forces perpendicular to the sliding direction), the first cavity 1012 serves as the deformation space for the first damping protrusion 110, thus preventing the damping force between the first support member 100 and the second support member 200 from being too large.

[0685] For example, the first thin wall is part of the first positioning member 170, or a thin-walled structure disposed in the first body 130 in any manner.

[0686] For example, both the first base plane 108 and the second base plane 109 are located on the first body 130.

[0687] For example, both the first base plane 108 and the second base plane 109 are located on the first positioning element 170.

[0688] In some implementations of this technical solution embodiment, refer to Figures 35-39 The first support member 100 is slidable relative to the second support member 200. The second support member 200 has a second damping protrusion 230. The second damping protrusion 230 makes damping contact with the first support member 100 so that when the telescopic leg 2a is in the supported state, the first support member 100 can be positioned on the second support member 200.

[0689] It is understandable that the first support member 100 can be positioned on the second support member 200 by means of the second damping protrusion 230.

[0690] For example, the first support member 100 is slidably sleeved on the second positioning member 220.

[0691] For example, the second positioning member 220 is disposed between the first support member 100 and the second main body 210, and the third base surface 2011 is adapted to the outer wall of the first support member 100.

[0692] For example, the third base surface 2011 is attached to the outer wall of the first support 100.

[0693] For example, the first support member 100 is slidably mounted on the second sliding groove 203, the second sliding groove 203 has two first side edges 203c along the sliding direction of the first support member 100, the distance between the two first side edges 203c is the maximum width of the second sliding groove 203, and two second damping protrusions 230 are located at or near the first side edges 203c respectively.

[0694] For example, the second positioning element 220 is in the form of a thin sheet, and the second positioning element 220 is detachably disposed on the second body 210;

[0695] For example, the second body 210 is provided with a first sliding groove 201, and the first support member 100 is slidably installed in the first sliding groove 201.

[0696] In some implementations of this technical solution embodiment, refer to Figures 35-39The second main body 210 is provided with a first sliding groove 201; the first sliding groove 201 is provided with a second limiting part 2019, and the second positioning member 220 is provided with a first limiting part 223. The second positioning member 220 is slidably inserted into the first sliding groove 201. After the second positioning member 220 is inserted into the first sliding groove 201, the first limiting part 223 and the second limiting part 2019 cooperate to restrict the second positioning member 220 within the first sliding groove 201; the second positioning member 220 is provided between the first support member 100 and the second main body 210. The second limiting part 2019 is a groove, and the first limiting part 223 is a protrusion. The first limiting part 223 is provided with a first sliding surface 209. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides past the second main body 210. Alternatively, the first limiting part 223 is a groove, the second limiting part 2019 is a protrusion, and the second limiting part 2219 is provided with a second sliding surface. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides past the second positioning member 220.

[0697] For example, the second positioning member 220 has a second cantilever 224 and a second deformation opening 2018. The second cantilever 224 is formed by extending from the edge of the second deformation opening 2018. A first limiting part 223 is provided on the second cantilever 224. During the process of the second positioning member 220 being inserted into the first sliding groove 201, the second deformation opening 2018 serves as the deformation space of the first cantilever 120.

[0698] For example, the first body 130 of the first support member 100 is provided with a first rotating cavity 107, a first rotating shaft 160 is provided in the first rotating cavity 107, and the first end of the first connecting rod 7 has a first rotating connector 7a, which is rotatably engaged with the first rotating shaft 160.

[0699] For example, the first rotation axis 160 is located at or near the center of the first body.

[0700] For example, in the initial state, the first end of the first link 7 can be located inside the first sliding groove 201. When the telescopic leg is extended to its maximum length, the first end of the first link 7 is located outside the first sliding groove 201. The advantage of this arrangement is that it allows the telescopic leg to extend further. When the first end of the first link 7 slides from inside the first sliding groove to outside the first sliding groove, the first clearance opening 1010 of the second body 210 and the second opening 204 of the second positioning member 220 serve as openings to clear the first link 7.

[0701] In some implementations of this technical solution embodiment, refer to Figure 35-41The second support member 200 has a second damping protrusion 230, which makes damping contact with the first support member 100 so that the first support member 100 can be positioned on the second support member 200 when the telescopic leg 2a is in the supported state; the second support member 200 has a third base surface 2011, the second damping protrusion 230 is located on the third base surface 2011 and protrudes relative to the third base surface 2011, and the third base surface 2011 is adapted to the outer wall of the first support member 100.

[0702] For example, the third base surface 2011 is attached to the outer wall of the first support member 100, the second support member 200 has a fourth base surface 2012, the fourth base surface 2012 and the third base surface 2011 are separated by a second thin wall, the second support member 200 is provided with a second cavity 2013, the second cavity 2013 is located on the fourth base surface 2012 and is recessed relative to the fourth base surface 2012, and the second cavity 2013 corresponds to the second damping protrusion 230.

[0703] For example, the second thin wall is part of the second positioning member 220, or the second thin wall is a thin wall structure disposed in the second body 210 in any manner.

[0704] For example, the second support member 200 is provided with a second sliding groove 203, and the first support member 100 is slidably installed in the second sliding groove 203. The second sliding groove 203 has two first side edges 203c along the sliding direction of the first support member 100. The distance between the two first side edges 203c is the maximum width of the second sliding groove 203. Two second damping protrusions 230 are respectively located at or near the first side edges 203c. The second support member 200 has a first end and a second end. When the length of the telescopic leg 2a is the longest, the first support member 100 extends from the first end of the second support member 200, and the second damping protrusions 230 are close to or located at the first end of the second support member 200.

[0705] In other implementations of this technical solution, the first support member 100 may be positioned on the second support member 200 so that the telescopic leg 2a can support the support rod 1, not limited to any of the following situations, or combinations thereof:

[0706] 1. The first support member 100 does not have a protruding structure. The outer side wall of the first support member 100 is in direct damped contact with the first sliding groove 201. Specifically, the outer side wall of the first positioning member is in direct damped contact with the first sliding groove 201 (for example, the first sliding part 140 is tightly fitted with the first sliding groove 201), so that the first support member 100 can be positioned on the second support member 200.

[0707] 2. The first support member 100 has a protruding structure, for example, the first damping protrusion 110 makes damping contact with the first sliding groove 201 so that the first support member 100 can be positioned on the second support member 200.

[0708] 3. The first support member 100 does not have a protruding structure. The first support member 100 is in damped contact with the second sliding groove 203. Specifically, the first body 130 is in direct damped contact with the second sliding groove 203 (e.g., the first body 130 and the second sliding groove 203 are tightly fitted), so that the first support member 100 can be positioned on the second support member 200.

[0709] 4. The second support member 100 has a protruding structure, for example, the second damping protrusion makes damping contact with the first support member 100 so that the first support member 100 can be positioned on the second support member 200.

[0710] 5. Both the first support member 100 and the second support member 200 have protruding structures. The first positioning protrusion 131 abuts against the second positioning protrusion 221 so that the first support member 100 can be positioned on the second support member 200.

[0711] Reference Figure 48-66 This technical solution embodiment also proposes a multi-leg bracket, which includes a support rod 1 and at least three legs 2. The at least three legs 2 are used to support the support rod 1, and the support rod 1 is used to support the electrical main body 3. At least one of the at least three legs 2 is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The second support member 200 is provided with a first sliding groove 201. The first support member 100 is sleeved in the first sliding groove 201. The first support member 100 is slidable relative to the first sliding groove 201. The first support member 100 and the first sliding groove 201 are in damped contact so that when the telescopic leg 2a is in the supporting state, the first support member 100 can be positioned on the second support member 200.

[0712] For example, refer to Figure 66 This technical solution embodiment proposes a shooting bracket, including a shooting terminal 3 and a multi-leg bracket. The support rod 1 of the multi-leg bracket is used to support the shooting terminal 3, which can be a mobile phone, tablet, etc.

[0713] In the multi-leg bracket implementing this technical solution embodiment, at least three of the legs 2 are telescopic legs 2a. When the multi-leg bracket is not in use, the first support member 100 can slide relative to the second support member 200, thereby shortening the length of the telescopic legs 2a and reducing the volume occupied by the multi-leg bracket. Furthermore, when using the multi-leg bracket, the length of the telescopic legs 2a is adjustable, allowing the multi-leg bracket to better adapt to uneven or inclined support surfaces.

[0714] For example, the damped contact between the first support 100 and the first sliding groove 201 can be achieved in any of the following ways:

[0715] 1. The outer wall of the first positioning member 170 is in damped contact with the first sliding groove 201;

[0716] 2. The outer wall of the first body 130 is in damped contact with the first sliding groove 201.

[0717] In some implementations of this technical solution, the first support member 100 includes a first main body 130 and a first positioning member 170 disposed on the first main body 130. The first positioning member 170 is slidably installed in the first sliding groove 201, and the first main body 130 is fitted inside the first sliding groove 201. The first positioning member 170 makes damping contact with the first sliding groove 201 so that when the telescopic leg 2a is in the supported state, the first support member 100 can be positioned on the second support member 200.

[0718] For example, the first positioning member 170 serves as a first sliding part 140 that slides in conjunction with the first sliding groove 201, so as to enable the first support member 100 to be slidably mounted on the second support member 200.

[0719] In some implementations of this technical solution, the second support member 200 is provided with a second sliding groove 203, the first support member 100 is sleeved in the second sliding groove 203, the first support member 100 is slidable relative to the first sliding groove 201, and the first support member 100 and the second sliding groove 203 make damping contact so that when the telescopic leg 2a is in the supporting state, the first support member 100 can be positioned on the second support member 200.

[0720] For example, the damped contact between the first support 100 and the second sliding groove 203 can be achieved in any of the following ways:

[0721] 1. The first outer wall of the first body 130 is in damped contact with the second sliding groove 203, for example, when the first outer wall of the first body 130 is only in damped contact with the second sliding groove 203;

[0722] 2. The first extrusion protrusion 191 protrudes from the first outer wall of the first body 130, and the first extrusion protrusion 191 makes damping contact with the second sliding groove 203.

[0723] In some implementations of this technical solution, the at least three legs are all telescopic legs; the multi-leg bracket further includes a first mounting part and at least three first connecting rods; the first mounting part is slidable relative to the support rod; the at least three first connecting rods correspond to the at least three telescopic legs respectively; the second support member is provided with a first sliding groove, the first support member is fitted into the first sliding groove, and the second support member is provided with a first clearance opening communicating with the first sliding groove; the first end of the first connecting rod is rotatably connected to the first support member of the corresponding telescopic leg through the first clearance opening, and the second end of the first connecting rod is rotatably connected to the support rod; when the first support member slides relative to the second support member of the telescopic leg, the first clearance opening serves as an opening to avoid the corresponding first connecting rod; during the sliding of the first mounting part along the support rod, the telescopic legs are retracted or opened relative to the support rod.

[0724] The three telescopic legs can be retracted to form the first columnar structure.

[0725] In some implementations of this technical solution, the second support member 200 includes a second main body 210 and a second positioning member 220 disposed on the second main body 210; the second positioning member 220 is provided with a second sliding groove 203; the first support member 100 is sleeved in the second sliding groove 203, the first support member 100 is slidable relative to the first sliding groove 201, and the first support member 100 is in damped contact with the second sliding groove 203 so that when the telescopic leg 2a is in the supporting state, the first support member 100 can be positioned on the second support member 200.

[0726] In some implementations of this technical solution, the second support member 200 is provided with a second sliding groove 203, the first support member 100 is sleeved in the second sliding groove 203, the first support member 100 is slidable relative to the second sliding groove 203, the first support member 100 is provided with a first extrusion protrusion 191, the first extrusion protrusion 191 is in extrusion contact with the inner wall of the second sliding groove 203 so that when the telescopic support leg 2a is in the support state, the first support member 100 can be positioned on the second support member 200.

[0727] In some implementations of this technical solution, the second support member 200 includes a second main body 210 and a second positioning member 220 disposed on the second main body 210, and a second sliding groove 203 is disposed on the second positioning member 220; during the sliding process of the first support member 100 relative to the second support member 200, the second positioning member 220 can slide past the first extrusion protrusion 191.

[0728] In some implementations of this technical solution, the edge of the first extrusion protrusion 191 gradually transitions to the outer wall of the first support member 100.

[0729] For example, the edge of the first extrusion protrusion 191 has a smooth transition or a beveled transition with the outer wall of the first support 100.

[0730] For example, the outer wall of the first extrusion protrusion 191 is a smooth curved surface or a sloping surface.

[0731] In some implementations of this technical solution, the second positioning member 220 has a third base surface 2011, which is adapted to the outer wall of the first support member 100. When the first extrusion protrusion 191 and the third base surface 2011 are in extrusion contact, the first support member 100 can be positioned on the second support member 200 when the telescopic leg 2a is in a supported state. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide past the first extrusion protrusion 191.

[0732] In some implementations of this technical solution, the second positioning member 220 has a third base surface 2011, which is adapted to the outer wall of the first support member 100. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide over the first extrusion protrusion 191. The second positioning member 220 is provided with a positioning cavity 2015 that is recessed relative to the third base surface 2011. During the sliding process of the first support member 100 relative to the second support member 200, the first extrusion protrusion 191 can slide into or out of the positioning cavity 2015. When the first extrusion protrusion 191 is located in the positioning cavity 2015, the first support member 100 can be positioned on the second support member 200.

[0733] In some implementations of this technical solution, the second positioning member 220 has a fourth base surface 2012, which is opposite to the third base surface 2011. A second thin wall is formed between the third base surface 2011 and the fourth base surface 2012. The third cavity 2014 is located on the fourth base surface 2012 and is recessed relative to the fourth base surface 2012. The second positioning member 220 is provided with two third cavities 2014, which are respectively close to the two ends of the second positioning member 220. The positioning cavity 2015 is located between the two third cavities 2014. During the process of the second positioning member 220 sliding over the first extrusion protrusion 191, the third cavity 2014 serves as the deformation space of the second positioning member 220.

[0734] For example, the second thin wall is part of the second positioning member 220, or the second thin wall is a thin wall structure disposed in the second body 210 in any manner.

[0735] In some implementations of this technical solution, the second positioning member 220 has a fourth base surface 2012, which is opposite to the third base surface 2011. The third base surface 2011 and the fourth base surface 2012 are separated by a second thin wall. The second positioning member 220 is provided with two third cavities 2014, which are located close to both ends of the second positioning member 220. During the process of the second positioning member 220 sliding over the first extrusion protrusion 191, the third cavity 2014 serves as the deformation space of the second positioning member 220.

[0736] In some implementations of this technical solution, the second support member 200 is provided with a second sliding groove 203, the first support member 100 is sleeved in the second sliding groove 203, the first support member 100 is slidable relative to the second sliding groove 203, the second sliding groove 203 has a third base surface 2011, the third base surface 2011 is adapted to the outer wall of the first support member 100, the first support member 100 is provided with a first pressing protrusion 191, the first pressing protrusion 191 and the third base surface 2011 press against each other so that when the telescopic support leg 2a is in the supporting state, the first support member 100 can be positioned on the second support member 200; during the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide past the first pressing protrusion 191.

[0737] For example, the second support member 200 has a fourth base surface 2012, which is opposite to the third base surface 2011. The third base surface 2011 and the fourth base surface 2012 form a second thin wall. The second support member 200 has two third cavities 2014, which are located on the fourth base surface 2012 and recessed relative to it. The two third cavities 2014 are respectively close to or located at both ends of the second thin wall. During the process of the second positioning member 220 sliding over the first extrusion protrusion 191, the third cavity 2014 serves as the deformation space of the second thin wall.

[0738] In some implementations of this technical solution, the second support member 200 is provided with a second sliding groove 203, and the first support member 100 is sleeved in the second sliding groove 203. The first support member 100 is slidable relative to the second sliding groove 203. The second sliding groove 203 has a third base surface 2011, which is adapted to the outer wall of the first support member 100. The first support member 100 is provided with a first extrusion protrusion 191. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide past the first extrusion protrusion 191. The second support member 200 is provided with a positioning cavity 2015 that is recessed relative to the third base surface 2011. During the sliding process of the first support member 100 relative to the second support member 200, the first extrusion protrusion 191 can slide into or out of the positioning cavity 2015. When the first extrusion protrusion 191 is located in the positioning cavity 2015, the first support member 100 can be positioned relative to the second support member 200.

[0739] For example, the second support member 200 has a fourth base surface 2012, which is opposite to the third base surface 2011. The third base surface 2011 and the fourth base surface 2012 form a second thin wall. The second support member 200 has two third cavities 2014, which are located on the fourth base surface 2012 and recessed relative to it. The two third cavities 2014 are respectively close to or located at both ends of the second thin wall. During the process of the second positioning member 220 sliding over the first extrusion protrusion 191, the third cavities 2014 serve as the deformation space of the second thin wall. The positioning cavity 2015 is located between the two third cavities 2014.

[0740] This technical solution embodiment also proposes a multi-leg bracket, which includes a support rod 1 and at least three legs 2. The at least three legs 2 are used to support the support rod 1, and the support rod 1 is used to support the electrical main body 3. At least one of the at least three legs 2 is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The first support member 100 can be positioned on the second support member 200 so that the telescopic leg 2a can support the support rod 1. The second support member 200 is provided with a second sliding groove 203. The first support member 100 is sleeved in the second sliding groove 203 and can slide relative to the second sliding groove 203. The first support member 100 is provided with a second pressing protrusion 192. The second pressing protrusion 192 presses against the inner wall of the second sliding groove 203 so that when the telescopic leg 2a is in the retracted state, the first support member 100 slides out of the second support member 200.

[0741] For example, the first support member 100 can be positioned on the second support member 200 in any of the ways described in this embodiment of the technical solution.

[0742] For example, the second support member 200 includes a second body 210 and a second positioning member 220 disposed on the second body 210, and a second sliding groove 203 disposed on the second positioning member 220; during the sliding process of the first support member 100 relative to the second support member 200, the second positioning member 220 can slide past the second extrusion protrusion 192.

[0743] For example, the edge of the second extrusion protrusion 192 gradually transitions to the outer wall of the first support 100.

[0744] For example, the second positioning member 220 has a third base surface 2011, which is adapted to the outer wall of the first support member 100. When the second extrusion protrusion 192 and the third base surface 2011 are in extrusion contact, the first support member 100 can be positioned on the second support member 200 when the telescopic leg 2a is in a supported state. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide past the second extrusion protrusion 192.

[0745] For example, the second positioning member 220 has a third base surface 2011, which is adapted to the outer wall of the first support member 100. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide over the second extrusion protrusion 192. The second positioning member 220 is provided with a positioning cavity 2015 that is recessed relative to the third base surface 2011. During the sliding process of the first support member 100 relative to the second support member 200, the second extrusion protrusion 192 can slide into or out of the positioning cavity 2015. When the second extrusion protrusion 192 is located in the positioning cavity 2015, the first support member 100 can be positioned on the second support member 200.

[0746] For example, the second positioning member 220 has a fourth base surface 2012, which is opposite to the third base surface 2011. A second thin wall is formed between the third base surface 2011 and the fourth base surface 2012. The second positioning member 220 is provided with two third cavities 2014, which are respectively close to or located at both ends of the second positioning member 220. The positioning cavity 2015 is located between the two third cavities 2014. During the process of the second positioning member 220 sliding over the second extrusion protrusion 192, the third cavity 2014 serves as the deformation space of the second positioning member 220.

[0747] For example, the second positioning member 220 has a fourth base surface 2012, which is opposite to the third base surface 2011. The third base surface 2011 and the fourth base surface 2012 are separated by a second thin wall. The second positioning member 220 is provided with two third cavities 2014, which are respectively close to the two ends of the second positioning member 220. During the process of the second positioning member 220 sliding over the second extrusion protrusion 192, the third cavity 2014 serves as the deformation space of the second positioning member 220.

[0748] This technical solution embodiment also proposes a multi-legged bracket, which includes a support rod 1 and at least three legs 2. The at least three legs 2 are used to support the support rod 1, and the support rod 1 is used to support the electrical main body 3. At least one of the at least three legs 2 is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The first support member 100 can be positioned on the second support member 200 so that the telescopic leg 2a can support the support rod 1. The second support member 200 is provided with a second sliding groove 203, and the first support member 100 is sleeved in the second sliding groove 203. The first support member 100 is slidable relative to the second sliding groove 203. The first support member 100 is provided with a second pressing protrusion 192. The second pressing protrusion 192 presses against the inner wall of the second sliding groove 203, so that when the telescopic support leg 2a is in the retracted state, the first support member 100 slides out of the second support member 200. The second support member 200 has a third base surface 2011, which is adapted to the outer wall of the first support member 100. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide past the second pressing protrusion 192.

[0749] For example, the second support member 200 has a fourth base surface 2012, which is opposite to the third base surface 2011. The third base surface 2011 and the fourth base surface 2012 form a second thin wall. The second support member 200 has two third cavities 2014, which are located on the fourth base surface 2012 and recessed relative to it. The two third cavities 2014 are respectively close to or located at both ends of the second thin wall. During the process of the second positioning member 220 sliding over the second extrusion protrusion 192, the third cavity 2014 serves as the deformation space of the second thin wall.

[0750] For example, the second thin wall is part of the second positioning element 220.

[0751] This technical solution embodiment proposes a multi-leg bracket, which includes a support rod 1 and at least three legs 2. The at least three legs 2 support the support rod 1, and the support rod 1 supports the electrical main body 3. At least one of the at least three legs 2 is a telescopic leg 2a. The telescopic leg 2a includes a first support member 100 and a second support member 200. The first support member 100 is positionable on the second support member 200 so that the telescopic leg 2a can support the support rod 1. The second support member 200 has a second sliding groove 203, and the first support member 100 is sleeved in the second sliding groove 203. The first support member 100 is slidable relative to the second sliding groove 203. The second sliding groove 203 has a third base surface 20. 11. The third base surface 2011 is adapted to the outer wall of the first support member 100. The first support member 100 is provided with a second pressing protrusion 192. During the sliding process of the first support member 100 relative to the second support member 200, the third base surface 2011 can slide over the second pressing protrusion 192. The second support member 200 is provided with a positioning cavity 2015 that is recessed relative to the third base surface 2011. During the sliding process of the first support member 100 relative to the second support member 200, the second pressing protrusion 192 can slide into or out of the positioning cavity 2015. When the second pressing protrusion 192 is located in the positioning cavity 2015, the first support member 100 slides out of the second support member 200 when the telescopic support leg 2a is in the retracted state.

[0752] For example, the second support member 200 has a fourth base surface 2012, which is opposite to the third base surface 2011. A second thin wall is formed between the third base surface 2011 and the fourth base surface 2012. The second support member 200 has two third cavities 2014, which are located on the fourth base surface 2012 and recessed relative to it. The two third cavities 2014 are respectively close to or located at both ends of the second thin wall. During the process of the second positioning member 220 sliding over the second extrusion protrusion 192, the third cavities 2014 serve as the deformation space of the second thin wall. The positioning cavity 2015 is located between the two third cavities 2014.

[0753] This technical solution embodiment also proposes a multi-leg bracket, the multi-leg bracket 1 including a support rod 1 and at least three legs 2, the at least three legs 2 for supporting the support rod 1, the support rod for supporting the electrical main body 3, at least one of the at least three legs 3 is a telescopic leg 2a, the telescopic leg 2a includes two first support members 100 and a second support member 200, the two first support members 100 are slidably sleeved on the second support member 200, the two first support members 100 can slide out relative to the two ends of the second support member 200 to change the length of the telescopic leg 2a; the first support members 100 can be positioned on the second support member 200 so that the telescopic leg 2a can support the support rod 1.

[0754] Specifically, the multi-leg bracket also includes a first mounting portion 5 and at least one first connecting rod 7. One end of the first connecting rod 7 is rotatably connected to one of the first support members 100, and the other end is rotatably connected to the support rod 1. The telescopic leg 2a is rotatably connected to the first mounting portion 5. When the first mounting portion 5 slides relative to the support rod 1, the angle of the telescopic leg 2a relative to the support rod 1 changes, allowing the telescopic leg 2a to be retracted into the support rod 1 or to open relative to the support rod 1.

[0755] This technical solution provides a multi-legged bracket, characterized in that the bracket includes a support rod and at least three legs, the at least three legs supporting the support rod, and the support rod supporting the electrical component. The bracket is characterized in that at least one of the at least three legs is a telescopic leg, comprising two first support members and a second support member. The two first support members are slidably fitted onto the second support member, and can slidably extend relative to both ends of the second support member to change the length of the telescopic leg. The first support members can be positioned on the second support member so that the telescopic leg can support the support rod. This design allows for a larger range of motion for the telescopic leg.

[0756] In the implementation of this technical solution embodiment, the telescopic support legs can be implemented in the following ways:

[0757] 1. The telescopic outrigger includes a first support member and a second support member, with the first support member sleeved on the second support member;

[0758] 2. The telescopic support leg includes two first support members and a second support member, and the two first support members are slidably sleeved on the second support member.

[0759] Reference Figures 67-68 This technical solution embodiment also proposes a method for implementing a telescopic support leg. The telescopic support leg includes a first support member 100 and a second support member 200. The first support member 100 is slidably sleeved on the second support member 200 to change the length of the telescopic support leg.

[0760] For example, the second support member 200 has a first sliding groove 201, and the first support member 100 is slidably sleeved in the first sliding groove 201.

[0761] When the first support member 100 is only subjected to tension or pressure along its sliding direction, the first support member 100 and the second support member 200 are loosely fitted, for example, the first sliding groove 201 of the first support member 100 and the second support member 200 are clearance fitted.

[0762] When the telescopic outrigger 2a supports the support rod 1, the first support member 100 is subjected to pressure along its sliding direction. The first support member 100 is also subjected to pressure perpendicular to its sliding direction (normal constraint force). The pressure perpendicular to the sliding direction causes friction between the first support member and the second support member (tangential constraint force).

[0763] The second support member 200 has a second contact surface 2016 that contacts the first support member 100. When the telescopic leg 2a is in the supported state, the constraint force of the second contact surface 2016 on the first support member 100 includes a normal constraint force perpendicular to the second contact surface 2016 and a tangential constraint force parallel to the second support surface 2016. The first support member 100 is subjected to a normal bearing force perpendicular to the second contact surface 2016 and a tangential bearing force parallel to the second contact surface 2016. When the tangential constraint force is equal to the tangential bearing force, the first support member 100 is positioned on the second support member 200.

[0764] For example, the second contact surface 2016 is the two opposite sides of the first sliding groove 201.

[0765] Reference Figures 98 to 106 (or Figures 107 to 119 This technical solution embodiment also proposes a telescopic support leg 2a, which includes a first support member and a second support member. The second support member is provided with a first sliding groove, and the first support member is sleeved in the first sliding groove. The first support member is slidable relative to the first sliding groove to change the length of the telescopic support leg. The first support member makes damping contact with the first sliding groove so that the first support member can be positioned on the second support member when the telescopic support leg is in a supported state. The first support member includes a first support body and a first damping protrusion protruding from the first support body. The first damping protrusion makes damping contact with the first sliding groove so that the first support member and the first sliding groove form a damping contact.

[0766] It is understood that the telescopic legs of this technical solution embodiment can be applied to the multi-leg bracket of this technical solution embodiment.

[0767] For example, the first sliding groove is a columnar groove, and the first support member is circumferentially fixed relative to the first sliding groove.

[0768] For example, the first sliding groove has two first sides extending along the sliding direction of the first support member, the distance between the two first sides being the maximum width of the first sliding groove, and the number of the first damping protrusions is two. The two first damping protrusions slide dampingly on the inner wall of the first sliding groove to form two first damping tracks, and the two first damping contact tracks are close to or located on the two first sides.

[0769] Other examples, see [reference] Figure 101 The number of first damping protrusions is 1, and 1 first damping protrusion is close to 1 of the first sides.

[0770] Other examples, see [reference] Figure 114 The number of first damping protrusions is 1, and the first damping protrusion is located near the middle position between the two first sides.

[0771] In some implementations of this technical solution embodiment, refer to Figure 101 The first support body includes a first body and a first sliding part protruding from the first body. The first sliding part is adapted to the first sliding groove. The first body and the first sliding groove have a first gap. The first sliding part is slidably installed in the first sliding groove so that the first support member can slide relative to the first sliding groove. The first damping protrusion protrudes from the first sliding part and makes damping contact with the inner wall of the first sliding groove. The first body is sleeved in the first sliding groove.

[0772] In some implementations of this technical solution, the first damping protrusion is detachably disposed on the first support body, the first support body is provided with a mounting groove adapted to the first damping protrusion, and the first damping protrusion is located in the mounting groove.

[0773] In some implementations of this technical solution embodiment, refer to Figure 101 The first damping protrusion is detachably disposed on the first sliding portion. The first sliding portion has a mounting groove 1013, which is adapted to the first damping protrusion. The first damping protrusion is detachably disposed on the mounting groove 1013. This placement of the first damping protrusion on the mounting groove 1013 prevents it from detaching from the first sliding portion during the sliding process of the first support member relative to the second support member. Separating the first damping protrusion from the first sliding portion facilitates the selection of a suitable damping material, allowing the telescopic support leg to achieve a good positioning effect within a reasonable cost. For example, the first damping protrusion may be made of silicone.

[0774] In some implementations of this technical solution embodiment, refer to Figure 101 or Figure 104The first damping protrusion has a damping contact surface 1014 and a deformation cavity 1015. The deformation cavity 1015 is connected to the damping contact surface 1014, and the damping contact surface 1014 surrounds the deformation cavity 1015. The advantages of providing the deformation cavity 1015 are that, on the one hand, during the process of the first support member being installed into the second support member, the first damping protrusion can easily deform using the deformation cavity 1015 to facilitate the installation of the first support member into the second support member; on the other hand, during the process of the first support member sliding relative to the second support member, the first damping protrusion can easily deform using the deformation cavity 1015 to avoid excessive damping force between the first support member and the second support member.

[0775] For example, the damping contact surface is annular, and the deformation cavity 1015 is cylindrical.

[0776] In other examples, the first damping protrusion does not have a deformation cavity 1015.

[0777] In other examples, the deformation cavity 1015 is located below the damping contact surface 1014 (i.e., the deformation cavity 1015 does not penetrate the damping contact surface 1014).

[0778] For example, refer to Figure 101 or Figure 104 The first damping protrusion is plate-shaped, for example, the first damping protrusion is circular.

[0779] For example, refer to Figure 101 or Figure 104 Before the first support is inserted into the second support, the damping contact surface 1014 can be planar. After the first support is inserted into the second support, the damping contact surface 1014 contacts the inner wall of the first sliding groove 101 (e.g., the first stretching surface 201a). The damping contact surface 1014 can adapt to the shape of the inner wall of the first sliding groove 101. For example, if the cross-section of the first stretching surface 201a is arc-shaped, the damping contact surface 1014 will deform into an arc surface after contacting the first stretching surface 201a.

[0780] In other examples, before the first support is inserted into the second support, the damping contact surface 1014 is a surface adapted to the inner wall of the first sliding groove 101. After the first support is inserted into the second support, the damping contact surface 1014 contacts the inner wall of the first sliding groove 101 (e.g., the first stretching surface 201a). For example, the cross-section of the first stretching surface 201a is arc-shaped, and the damping contact surface 1014 itself is an arc surface adapted to the first stretching surface 201a.

[0781] For example, refer to Figure 101The first sliding groove has two first sides extending along the sliding direction of the first support member. The distance between the two first sides is the maximum width of the first sliding groove. The number of the first damping protrusions is one. The one first damping protrusion slides dampingly on the inner wall of the first sliding groove to form a first damping trajectory. The one first damping contact trajectory is close to or located on one of the first sides.

[0782] In another example, the first sliding groove has two first sides extending along the sliding direction of the first support member, the distance between the two first sides being the maximum width of the first sliding groove, and the number of the first damping protrusions is two. The two first damping protrusions slide dampingly on the inner wall of the first sliding groove to form two first damping tracks, and the two first damping contact tracks are close to or located on the two first sides.

[0783] Other examples, see [reference] Figure 114 For example, the first sliding groove has two first sides extending along the sliding direction of the first support member, the distance between the two first sides is the maximum width of the first sliding groove, the number of the first damping protrusions is one, the one first damping protrusion slides dampingly on the inner wall of the first sliding groove to form a first damping trajectory, and the one first damping contact trajectory is close to or located at the middle position between the two first sides.

[0784] For example, the first support member of the telescopic leg can be housed in the corresponding second support member, and when the first support member is housed in the second support member, the first support member can be positioned on the second support member.

[0785] In other implementations of this technical solution embodiment, refer to Figure 101The first damping protrusion has a damping contact surface that directly dampens the second support member. There are two first damping protrusions. The line connecting any two points of the damping contact surfaces of the two first damping protrusions forms a first connecting line. The angle between the first connecting line and the first straight line is greater than or equal to 75° and less than or equal to 90°. The second support member is provided with a first sliding groove, and the first support member is slidably installed in the first sliding groove. The length of the first connecting line is 70%-100% of the maximum width of the first sliding groove. The first sliding groove is a columnar groove, and the first support member is circumferentially fixed relative to the first sliding groove. The first sliding groove has two first sides extending along the sliding direction of the first support member. The distance between the two first sides is the maximum width of the first sliding groove. The two first sides are symmetrical about a first symmetry plane. There are two first damping protrusions. The two first damping protrusions slide dampingly on the inner wall of the first sliding groove to form two first damping tracks. The two first damping contact tracks are close to or located on the two first sides. The angle between the first connecting line and the first straight line is 90°. The first support member of the telescopic leg can be housed in the corresponding second support member. When the first support member is housed in the second support member, the first support member can be positioned on the second support member.

[0786] In some implementations of this technical solution, the number of the first damping protrusions is two, the two first damping protrusions are symmetrical about the first symmetry plane, the first sliding groove is a columnar groove, and the axis of the first sliding groove is located in the first symmetry plane.

[0787] In some implementations of this technical solution, the number of the first damping protrusions is two, and the line connecting any two points of the damping contact surface of the two first damping protrusions forms a first connecting line. The second support member is provided with a first sliding groove, and the first support member is slidably installed in the first sliding groove. The length of the first connecting line is 70%-100% of the maximum width of the first sliding groove.

[0788] Reference Figures 107 to 119This technical solution embodiment also proposes a telescopic support leg, which includes a first support member and a second support member. The first support member is sleeved on the second support member, and the first support member is slidable relative to the second support member to change the length of the telescopic support leg. The first support member includes a first body and a first positioning member disposed on the first body. The first positioning member has a first damping protrusion, which makes damping contact with the second support member so that the first support member can be positioned on the second support member when the telescopic support leg is in a supported state. The second support member has a first sliding groove, and the shape of the first positioning member is adapted to the first sliding groove. The first positioning member is slidably installed in the first sliding groove, the first body is sleeved in the first sliding groove, and the first positioning member is located between the first body and the second support member.

[0789] It is understood that the telescopic legs of this technical solution embodiment can be applied to the multi-leg bracket of this technical solution embodiment.

[0790] In some implementations of this technical solution embodiment, refer to Figure 114 The first damping protrusion is detachably disposed on the first positioning member. The first damping protrusion has a first mounting sub-groove 1013a, which is adapted to the first damping protrusion. The first damping protrusion is located in the first mounting sub-groove 1013a. The detachable placement of the first damping protrusion in the first mounting sub-groove 1013a prevents it from detaching from the first positioning member during the sliding process of the first support member relative to the second support member. Separating the first damping protrusion from the first positioning member facilitates the selection of a suitable damping material, enabling the telescopic outrigger to achieve a good positioning effect within a reasonable cost.

[0791] For example, the first mounting sub-slot 1013a is a blind slot, and the first damping protrusion is located between the first positioning member and the second support member.

[0792] For example, refer to Figure 114 The first mounting sub-groove 1013a passes through the first positioning member, and the first damping protrusion is located between the first main body and the second support member.

[0793] In some implementations of this technical solution embodiment, refer to Figure 114 The first main body is provided with a second mounting sub-groove 1013b, the first mounting sub-groove 1013a passes through the first positioning member, the second mounting sub-groove 1013b is positioned corresponding to the first mounting sub-groove 1013a, the first damping protrusion is located in the second mounting sub-groove 1013b, and the first damping protrusion is separable from the second mounting sub-groove 1013b. The advantage of providing the second mounting sub-groove 1013b is that it makes the first damping protrusion less likely to detach from the first positioning member.

[0794] Understandably, referring to Figure 114 The first positioning element and the first main body constitute the first support body. The first positioning element serves as the first sliding part 140 that slides in cooperation with the first sliding groove 201. The first sliding part 140 is circumferentially fixed to the first sliding groove 201. The first mounting sub-groove 1013a serves as the mounting groove 1013, or the first mounting sub-groove 1013a and the second mounting sub-groove 1013b together constitute the mounting groove 1013.

[0795] For example, refer to Figure 114 The first positioning member has a first base surface, which is adapted to the inner wall of the first sliding groove, and the first mounting sub-groove 1013a is connected to the first base surface.

[0796] For example, refer to Figure 114 The first positioning element is detachably disposed on the first body. The first positioning element is in the form of a thin sheet. The first positioning element has a first opening. The first positioning element can be inserted into the first body through the first opening.

[0797] For example, the first positioning member is detachably disposed on the first body. When the first support member slides relative to the second support member, the first positioning member is fixed relative to the first body. The first body is provided with two retaining walls, and the first positioning member is retained between the two retaining walls so that when the first support member slides relative to the second support member, the first positioning member is fixed relative to the first body.

[0798] For example, the first support member has a first end and a second end, and when the telescopic leg is at its longest length, the first end of the first support member extends from the second support member, and the first damping protrusion is close to or located at the second end of the first support member.

[0799] For example, the first support member has a first positioning protrusion, and the second support member has a second positioning protrusion. During the sliding process of the first support member relative to the second support member, the first positioning protrusion can abut against or slide past the second positioning protrusion. When the first positioning protrusion abuts against the second positioning protrusion, the first support member can be positioned relative to the second support member when the telescopic leg is in the supported state.

[0800] For example, the second positioning member has a second sliding groove adapted to the first body, the first body is slidably mounted on the second sliding groove, the second sliding groove has two first side edges along the sliding direction of the first body, the distance between the two first side edges is the maximum width of the second sliding groove; the second positioning member is in the form of a thin sheet, and the second positioning member is detachably disposed on the second body.

[0801] Reference Figures 107 to 119 This technical solution embodiment also proposes a multi-leg bracket, wherein at least three legs of the multi-leg bracket are telescopic legs; the multi-leg bracket further includes a first mounting part and at least three first connecting rods; the first mounting part is slidable relative to the support rod; the at least three first connecting rods respectively correspond to the at least three telescopic legs; the second support member is provided with a first clearance opening communicating with the first sliding groove; the first end of the first connecting rod is rotatably connected to the first support member of the corresponding telescopic leg through the first clearance opening, and the second end of the first connecting rod is rotatably connected to the support rod; when the first support member slides relative to the second support member of the telescopic leg, the first clearance opening... The opening serves as an opening to avoid the corresponding first connecting rod; during the sliding of the first mounting part along the support rod, the telescopic leg is retracted or opened relative to the support rod; the telescopic leg has a second receiving space, the first support member of the telescopic leg can be received in the second support member, after the first support member of the telescopic leg is received in the second support member, the telescopic leg can be received in the support rod, during the process of the telescopic leg being received in the support rod, the first connecting rod is received in the second receiving space through the first avoidance opening, and after at least three telescopic legs are received in the support rod, the at least three telescopic legs form a first columnar structure.

[0802] For example, the first support member of the telescopic leg can be housed in the second support member, and when the first support member of the telescopic leg is housed in the second support member, the first support member can be positioned on the second support member.

[0803] For example, refer to Figure 109 and Figure 111 The first connecting rod 7 has a first rotating connector 7a at its first end and a second rotating connector 7b at its second end. The first main body 130 of the first support member 100 is provided with a first rotating cavity 107. The first rotating connector 7a is rotatably engaged with the first rotating cavity 107. The support rod 1 has a second rotating cavity 1001. The second rotating connector 7b is rotatably engaged with the second rotating cavity 1001.

[0804] The above is only used to illustrate the technical solution of this invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this invention, as long as they do not depart from the spirit and scope of this technical solution, should be covered within the scope of the claims of this technical solution.
