[0191] For example, the power-consuming subject 3 can be a fan, a lamp, a mobile phone, a tablet, etc. For example, the fan and the lamp are fixedly or movably installed on the support rod 1, and the mobile phone and the tablet can be clamped by a clamp 4, and the clamp 4 is fixedly or movably installed on the support rod 1.

[0192] For example, refer to Fig. 27 The embodiment of the utility model proposes a shooting bracket, including a shooting terminal 3 and a multi-legged bracket, wherein a support rod 1 of the multi-legged bracket is used to support the shooting terminal 3, and the shooting terminal 3 can be a mobile phone, a tablet, etc.

[0193] For example, at least one leg 2 is fixedly mounted on the support rod 1, for example, at least one telescopic leg 2a is fixedly mounted on the support rod 1, for example, the first support member or the second support member of the telescopic leg 2a is fixedly mounted on the support rod.

[0194] For example, at least three legs 2 are fixedly mounted on the support rod 1, and at least three legs 2 can be radially opened relative to the support rod 1. For example, all legs 2 are telescopic legs 2a, and at least three telescopic legs 2a are fixedly mounted on the support rod 1, and at least three telescopic legs 2a can be radially opened relative to the support rod 1.

[0195] 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 support member or the second support member of the telescopic leg 2a is directly or indirectly rotatably connected to the support rod.

[0196] For example, at least one support leg 2 can be retracted or unfolded relative to the support rod 1 , for example, at least one telescopic support leg 2 a can be retracted or unfolded relative to the support rod 1 .

[0197] For example, at least three legs 2 can be stored or opened relative to the support rod 1, and after the first support member 100 of the telescopic leg 2a is stored in the second support member 200 of the telescopic leg 2a, the at least three legs 2 can be stored in the support rod 1, for example, at least three legs 2 are movably installed on the support rod 1, when the at least three legs 2 support the support rod 1, the at least three legs 2 are radially opened relative to the support rod 1; when the multi-legged bracket is not in use, the at least three legs 2 can be folded together, or at least three legs 2 can be stored in the support rod 1. For example, after the at least three legs 2 are stored in the support rod 1 and the first support member 100 is stored in the second support member 200, the 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.

[0198] For example, at least three legs 2 are telescopic legs 2a, and after at least three legs 2 are stored in the support rod 1 and the first support member 100 is stored 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 arched or fan-shaped, and when the at least three telescopic legs 2a are folded, the second support members 200 of the at least three telescopic legs 2a are folded to form a cylindrical first columnar structure.

[0199] By way of example, the first columnar structure is a cylinder; the support rod is a telescopic rod, the number of sections of the telescopic rod is 7 or more, the length of the telescopic rod in the extended state exceeds 1.4 meters, the length of the telescopic rod in the stored state is less than or equal to 32 centimeters, and the diameter of the first columnar structure is less than or equal to 42 millimeters.

[0200] For example, at least three legs 2 may be of equal length, or at least two legs 2 among the at least three legs 2 may be of equal length, or at least three legs 2 may be of unequal length.

[0201] 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 the angles of any two legs 2 relative to the support rod 1 are different.

[0202] For example, when the multi-legged stand is in a supporting state, the support rod 1 is perpendicular to the supporting surface, or the support rod 1 is inclined relative to the supporting surface.

[0203] For example, when the multi-legged support is in a supporting state, the support rod 1 is along a plumb line, or the support rod 1 is inclined relative to the plumb line.

[0204] For example, at least one of the at least three legs 2 is a telescopic leg 2 a, and the remaining legs 2 are legs 2 of fixed length.

[0205] For example, at least three legs 2 are telescopic legs 2a. The advantage of such a configuration is that when the multi-legged stand is used, the length of the telescopic legs 2a can be adjusted, so that the supporting area of ​​the multi-legged stand can be changed. 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 supporting area of ​​the multi-legged stand.

[0206] For example, at least three legs 2 are telescopic legs 2a, and after the at least three telescopic legs 2a change their lengths, 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).

[0207] For example, at least three legs 2 are telescopic legs 2a, and after at least three legs 2 change their lengths, the angle between the support rod 1 and the plumb line remains unchanged (for example, the support rod 1 is always along the plumb line, or has an angle with the plumb line).

[0208] For example, the first support member 100 is sleeved on the second support member 200 , and the second support member 200 completely surrounds the first support member 100 , or the second support member 200 partially surrounds the first support member 100 .

[0209] 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 tightly matched, and the first damping protrusion 110 and the second support member 200 have friction, so that the first support member 100 can be positioned on the second support member 200 .

[0210] 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 is in damping contact with the inner wall of the first sliding groove 201 .

[0211] For example, the first sliding groove 201 has a first stretching surface 201 a and a second stretching surface 201 b opposite to each other, and the first stretching surface 201 a and the second stretching surface 201 b restrict the first support member 100 within the first sliding groove 201 .

[0212] For example, the first support member 100 is fully, half, or partially surrounded by the second support member 200 .

[0213] In some implementations of the present invention, reference is made to Fig.15 , or refer to Fig.78 , Fig.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 .

[0214] For example, the cross section of the first sliding groove 201 is "c" shaped, the first support member 100 has a portion with a "c" shaped cross section, and the "c" shaped portion of the first support member 100 cooperates with the first sliding groove 201. For example, the first sliding groove 201 can be a closed "c" shaped groove, or have an open "c" shaped groove. The advantage of such a setting is that the structural strength of the telescopic leg 2a is improved.

[0215] For example, the cross section of the first sliding groove 201 is semicircular, elliptical, polygonal, etc. Correspondingly, the first support member 100 has a portion with a semicircular, elliptical, polygonal cross section (and the portion cooperates with the first sliding groove 201 ).

[0216] For example, for a cylindrical geometric body, the line along the geometric center of its cross section is its axis, the direction along the axis is the axial direction of the cylindrical geometric body, the direction along the geometric center of the cross section and perpendicular to the axis is the radial direction of the cylindrical geometric body, and the direction around its axis is the circumferential direction of the cylindrical geometric body.

[0217] It can be understood 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, which means that when the telescopic leg 2a is in the supporting state, the first support member 100 can be maintained on the second support member 200.

[0218] It can be understood that when the first support member 100 is stored in the second support member 200, the damping contact between the first support member 100 and the second support member 200 can position the first support member 100 in the second support member 200 (ie, the first support member 100 remains in a stored state relative to the second support member 200).

[0219] In other examples, the first sliding groove 201 is a columnar groove with a cross section of any other shape, such as a cylindrical groove, and the first sliding portion 140 is a columnar body with a cross section of any other shape, such as a cylinder.

[0220] In some implementations of the present utility model, referring to Fig. 9 , Fig.15 , or refer to Fig.78 , Fig.81 The first support member 100 includes a first support body and a first damping protrusion 110 protruding from the first support body. The damping contact between the first damping protrusion 110 and the first sliding groove 201 can form a damping contact between the first support member 100 and the first sliding groove 201. The advantage of providing the first damping protrusion 110 is that friction damping can be provided for the first support member 100 and the second support member 200 at any position where the first damping protrusion 110 and the first sliding groove 201 are in damping contact.

[0221] For example, the first damping protrusion 110 is protruded from the first support body, and the first support body is sleeved in the first sliding groove 201. One implementation method of the damping contact between the first support member 100 and the second support member 200 is that only the first damping protrusion 110 is in damping contact with the first sliding groove 201, and the first support body and the first sliding groove 201 are not in contact (there is a gap between the first support body and the first sliding groove 201). For example, the first damping protrusion 110 is strip-shaped, the first damping protrusion 110 is ring-arranged on the first support body, and the first damping protrusion 110 is a plurality of protrusions arranged at intervals, and the plurality of protrusions are arranged at intervals. In this implementation method, the friction 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.

[0222] Another implementation method of the damping contact between the first support member 100 and the second support member 200 is that the first damping protrusion 110 is in damping contact with the second support member 200. Due to the shape of the first damping protrusion 110, when the first damping protrusion 110 is in damping contact with the first sliding groove 201, the first supporting body of the first support member 100 is also in damping contact with the first sliding groove 201. In this implementation method, the friction force 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.

[0223] For example, the first damping protrusion 110 is in damping contact with the first stretching surface 201a so that the first support member 100 can be positioned on the second support member 200, and the first sliding groove 201 has a first stretching surface 201a and a second stretching surface 201b relative to each other. The first stretching surface 201a and the second stretching surface 201b are used to confine the first support member 100 in the first sliding groove 201. In this case, the first support body is in damping contact with the second stretching surface 201b.

[0224] For example, the number of the first damping protrusions 110 is 1, 2, 3, 4, etc.

[0225] It can be understood that the first support member 100 can be positioned on the second support member 200 through the first damping protrusion 110 between the first support member 100 and the second support member 200 .

[0226] For example, the first damping protrusion 110 is close to or located at the second end of the first support member 100 .

[0227] In other examples, the first support member 100 is positioned on the second support member 200 by direct damping contact between the outer side wall of the first sliding portion 140 and the first sliding groove 201 .

[0228] In some implementations of the present utility model, referring to Fig. 9 , 12, 15, etc., the first support body is provided with a first deformation opening 101 and a first cantilever 120 formed by extending the edge of the first deformation opening 101, the first damping protrusion 110 is protrudingly provided on the first cantilever 120, the first cantilever 120 is configured to apply elastic force to the first damping protrusion 110 so that the first damping protrusion 110 is in damping contact with the first sliding groove 201, and the first deformation opening 101 serves as a deformation space of the first cantilever 120. On the one hand, when the first damping contact protrusion is in damping contact with the first sliding groove 201, the first deformation opening 101 serves as a deformation space of the first cantilever 120, thereby avoiding excessive damping force between the first support member 100 and the second support member 200, and on the other hand, when the first support member 100 is installed in the first sliding groove 201, the first deformation opening 101 serves as a deformation space of the first cantilever 120, thereby making it easy for the first support member 100 to be installed into the second support member 200.

[0229] By way of example, the first deformation opening 101 is provided on the first supporting body of the first supporting member 100 .

[0230] For example, the first deformation opening 101 is provided through the first support member 100 .

[0231] For example, the first cantilever 120 is located in the first deformation opening 101 and does not protrude from the outer wall of the first support body. The advantage of such a configuration is that it is more convenient to install. (More preferably, the first cantilever 120 is flush with the outer wall of the first support body).

[0232] In some implementations of the present utility model, referring to Fig. 9 , 15 The first sliding groove 201 has two first side edges 201c extending along the sliding direction of the first support member 100, the distance between the two first side edges 201c is the maximum width of the first sliding groove 201, the number of the first damping protrusions 110 is two, the two first damping protrusions 110 dampingly slide on the inner wall of the first sliding groove 201 to form two first damping contact tracks, and the two first damping contact tracks are close to or located at the two first side edges 201c. The advantage of such a setting is that the damping force received by the first support member 100 can act on itself as a whole, so that the telescopic bracket is more stable when telescoping.

[0233] For example, the first support body is symmetrical about a first symmetry plane, and the first symmetry plane is parallel to the extension direction of the support body 1a. When the first support member 100 is assembled in 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, and the two first damping protrusions 110 are symmetrical about the first symmetry plane.

[0234] For example, the two first damping contact tracks are located on the first stretching surface 201 a of the first sliding groove 201 .

[0235] In some implementations of the utility model, referring to 9, 15, etc., the first supporting body includes a first body 130 and a first sliding portion 140 protruding from the first body 130, the first sliding portion 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 portion 140 is slidably installed in the first sliding groove 201 so that the first support member 100 can slide relative to the first sliding groove 201; the first damping protrusion 110 is protruding from the first sliding portion 140, the first damping protrusion 110 is in damping contact with the inner wall of the first sliding groove 201, and the first body 130 is sleeved in the first sliding groove 201. The advantage of providing the first sliding portion 140 is that the first support member 100 and the first sliding groove 201 are more stable when sliding, and the shaking of the first support member 100 when sliding relative to the first sliding groove 201 is reduced. On the other hand, the first support body slides with the first sliding groove 201 through the first sliding portion 140, thereby reducing the friction resistance between the first support member 100 and the second support member 200, making it easier to stretch or store the telescopic leg 2a.

[0236] For example, the first sliding groove 201 has a first stretching surface 201a and a second stretching surface 201b, and the first stretching surface 201a and the second stretching surface 201b have the same extension direction. The first stretching surface 201a and the second stretching surface 201b restrict the first sliding portion 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 an arc, and the cross-section of the second stretching surface 201b is a plane or a folded surface, etc.

[0237] For example, the first avoidance opening 2010 passes through the second stretching surface 201 b.

[0238] By way of example, the cross section of the first sliding groove 201 is adapted to the cross section of the first sliding portion 140 .

[0239] For example, the length of the first sliding portion 140 along the sliding direction is 30%-100% (eg, 30%, 50%, 70%, 100%, etc.) of the maximum width of the first sliding groove 201 .

[0240] For example, the first sliding groove 201 is a columnar groove, the first sliding groove 201 has a first axis, and the first sliding portion 140 is circumferentially fixed relative to the first sliding groove 201 around the first axis.

[0241] For example, the cross section of the first sliding groove 201 is in a “c” shape, and the cross section of the first sliding portion 140 is in a “c” shape.

[0242] For example, the cross section of the first sliding groove 201 is semicircular, elliptical, polygonal, etc., and correspondingly, the cross section of the first sliding portion 140 is semicircular, elliptical, polygonal, etc.

[0243] In other examples, the first slide groove is a columnar groove with any other cross-sectional shape, such as a cylindrical groove. Accordingly, the first sliding portion 140 is a columnar body with any other cross-sectional shape, such as a cylinder.

[0244] In other examples, the first sliding portion 140 is coaxially rotatable relative to the first sliding groove 201 .

[0245] It can be understood that when the first support member 100 and the second support member 200 are only slidably matched with each other by the first sliding portion 140 and the first sliding groove 201 , the first support member 100 can be slidably installed on the second support member 200 .

[0246] In some implementations of the present utility model, referring to Fig. 9 , 15 The first sliding portion 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, the first protrusion is protruded 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 is in damping contact with the first sliding groove 201, and the first deformation opening 101 serves as a deformation space of the first cantilever 120.

[0247] For example, the first deformation opening 101 is disposed through the first sliding portion 140 .

[0248] For example, the first cantilever 120 is located in the first deformation opening 101 and does not protrude from the outer wall of the first sliding portion 140 . The advantage of such a configuration is that it is more convenient to install. More preferably, the outer wall of the first cantilever 120 is flush with the outer wall of the first sliding portion 140 .

[0249] In some implementations of the present utility model, referring to Fig. 9 , 15 The first sliding groove 201 has two first side edges 201c extending along the sliding direction of the first support member 100, the distance between the two first side edges 201c is the maximum width of the first sliding groove 201, the number of the first damping protrusions 110 is two, the two first damping protrusions 110 dampingly slide on the inner wall of the first sliding groove 201 to form two first damping contact tracks, and the two first damping contact tracks are close to or located at the two first side edges 201c. The advantage of such a setting is that the first support member 100 is more stable when sliding relative to the second support member 200.

[0250] For example, the first sliding portion 140 is symmetrical about a first symmetry plane, and the first symmetry plane is parallel to the extension direction of the support body 1a. When the first support member 100 is assembled in the first sliding groove 201, the first axis is located in the first symmetry plane. The number of the first damping protrusions 110 is 2, and the two first damping protrusions 110 are symmetrical about the first symmetry plane. The axis of the first sliding groove 201 is located in the first symmetry plane.

[0251] For example, the two first damping contact tracks are located on the first stretching surface 201 a of the first sliding groove 201 .

[0252] For example, the connection line of any two points of the damping contact surface of the two first damping protrusions 110 forms a first connection line, the first support member 100 extends along the first straight line, and the angle between the first connection line and the first straight line is greater than or equal to 75° and less than or equal to 90° (for example, 75°, 80°, 85°, 90°, etc.). The advantage of such a setting is that the first support member 100 has a more stable positioning effect relative to the second support member 200.

[0253] 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 such a setting 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.

[0254] For example, the first sliding groove 201 has two first side edges 201c extending along the sliding direction of the first support member 100, the distance between the two first side edges 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 side edges 201c are respectively located in the first sliding sub-groove 201d and the second sliding sub-groove 201e, the first sliding portion 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, 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.

[0255] For example, when the telescopic leg 2 a is at its longest length, the first body 130 extends from the second support member 200 , and when the telescopic leg 2 a is at its shortest length, the first body 130 is accommodated in the second support member 200 .

[0256] In some implementations of the present utility model, referring to Fig.17The first sliding portion 140 is provided with a first limiting wall 102 , and the second supporting member 200 has a second limiting wall 202 . When the length of the telescopic leg 2 a is the longest, the first limiting wall 102 and the second limiting wall 202 abut against each other.

[0257] For example, the first sliding portion 140 is protruded from the first body 130 , and the first limiting wall 102 is located on a side of the first sliding portion 140 .

[0258] In some implementations of the present utility model, refer to 17, or refer to Fig.80 , Fig.81 , Fig.82 The first 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 over the second positioning protrusion 221. When the first positioning protrusion 131 and the second positioning protrusion 221 abut against each other, the first support member 100 can be positioned on the second support member 200 when the telescopic support leg 2a is in the supporting state. The advantage of providing the first positioning protrusion 131 and the second positioning protrusion 221 is that when the first positioning protrusion 131 and the second positioning protrusion 221 abut against each other, additional abutting force is provided for the first support member 100 relative to the second support member 200, further enhancing the stability of the telescopic support leg 2a in the supporting state. In addition, the first positioning protrusion 131 can slide over the second positioning protrusion 221, without affecting the storage of the telescopic support leg 2a, and after the telescopic support leg 2a is stored, it does not affect the extension of the telescopic support leg 2a.

[0259] For example, the first positioning protrusion 131 is protruded from the first body 130 , and the second positioning protrusion 221 is protruded from the second positioning member 220 .

[0260] By way of example, the first positioning protrusion 131 is a side wall of the groove of the first body 130 , and the second positioning protrusion 221 is a side wall of the groove of the first body 130 .

[0261] For example, the number of the first positioning protrusions 131 may be 1, 2, 3, etc., and the number of the second positioning protrusions 221 may be 1, 2, 3, etc.

[0262] For example, when the first positioning protrusion 131 abuts against the second positioning protrusion 221 , an additional abutting force is provided for the first support member 100 relative to the second support member 200 .

[0263] For example, the first positioning protrusion 131 sliding over the second positioning protrusion 221 may mean that when the telescopic leg 2a is in a supporting state, the first positioning protrusion 131 is in a state of abutment against the second positioning protrusion 221, and when the pressure applied to 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 stored in the second support member 200.

[0264] For example, the first positioning protrusion 131 sliding over the second positioning protrusion 221 can also mean that, when the telescopic leg 2a is in a retracted state, the second positioning protrusion 221 and the first positioning protrusion 131 do not abut against each other, and the second positioning protrusion 221 is located between the first end of the first support member 100 and the first positioning protrusion 131. When the pulling force applied to the telescopic leg 2a is large enough, 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 positioning of the first support member 100 on the second support member 200 in the supporting state.

[0265] Obviously, the abutment between the first positioning protrusion 131 and the second positioning protrusion 221 enables the first support member 100 to be positioned on the second support member 200 when the telescopic leg 2a is at a specific length.

[0266] For example, in one implementation, the telescopic leg 2 a achieves positioning of the first support member 100 on the second support member 200 through cooperation between the first positioning protrusion 131 and the second positioning protrusion 221 .

[0267] It is understandable that, when the first positioning protrusion 131 slides over the second positioning protrusion 221 , the first positioning protrusion 131 is deformed and / or the second positioning protrusion 221 is deformed, so that the first positioning protrusion 131 can slide over the second positioning protrusion 221 .

[0268] In some implementations of the present utility model, referring to Fig.17 etc., or refer to Fig.80 , Fig.81 , Fig.82The 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, the second positioning member 220 is 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 can slide relative to the second support member 200, the first support member 100 is sleeved on the second main body 210, and the 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 the first support member 100 is slidably mounted on the first sliding groove 201, thereby improving the stability of the first support member 100 when sliding.

[0269] For example, the first body 130 of the first supporting member 100 is slidably mounted on the second positioning member 220 .

[0270] For example, the second positioning member 220 can be detachably disposed on the second body 210 .

[0271] For example, the second positioning member 220 is in the shape of a thin sheet, and the second positioning member 220 surrounds or partially surrounds the first body 130 .

[0272] For example, the second positioning member 220 is in the shape of a thin sheet, and the second positioning member 220 is attached to the inner wall of the first sliding groove 201 .

[0273] For example, the second positioning member 220 surrounds to form the second sliding groove 203, the first body 130 of the first support member 100 is slidably sleeved in the second sliding groove 203, and the first sliding groove 201 and the second sliding groove 203 are coaxial or extend in the same direction. Obviously, the second sliding groove 203 is a stretching groove (i.e., a columnar groove).

[0274] By way of example, the second sliding groove 203 is a columnar groove, and the first body 130 is circumferentially fixed around the second sliding groove 203 .

[0275] For example, the second positioning member 220 has a third stretching surface 203a and a fourth stretching surface 203b opposite to each other, and the third stretching surface 203a and the fourth stretching surface 203b work together to restrict the first body 130 in the second sliding groove 203. For example, the second positioning protrusion 221 is protruding from the fourth stretching surface 203b.

[0276] For example, the first avoidance opening is communicated with the second sliding groove.

[0277] In other examples, the second positioning protrusion 221 is disposed on the second body 210 , for example, the second positioning protrusion 221 is integrally disposed on the second body 210 .

[0278] For example, the second positioning member 220 is fixedly mounted on the second body 210 , and the second positioning member 220 is detachable relative to the second body 210 .

[0279] For example, the second positioning member 220 can be inserted into the first sliding groove 201 and fixed to the second body 210 .

[0280] For example, the second positioning member 220 is in the shape of a thin sheet with a second opening 204 . When the second positioning member 220 is installed into the first sliding groove 201 , the second positioning member 220 is squeezed and deformed as a whole, so that the second positioning member 220 is easily installed into the first sliding groove 201 .

[0281] For example, the second positioning member 220 is in the shape of a thin sheet having a second opening 204, and the second opening 204 passes through the outer wall of the second positioning member 220 to the fourth stretching surface 203b. When the second positioning member 220 needs to be removed, the second positioning member 220 is compressed to shrink the second opening 204, so that the second positioning member 220 can be removed from the second body 210.

[0282] It can be understood that the sliding fit between the first support member 100 and the second support member 200 can be achieved only by the sliding fit between the first support member 100 and the second positioning member 220 .

[0283] In some implementations of the present utility model, referring to Figure 2 etc. or refer to Fig.81 The first body 130 has a first end and a second end. When the length of the telescopic leg 2a is the longest, 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 such a configuration is that the telescopic leg 2a has a longer support length, and the first positioning protrusion 131 makes the telescopic leg 2a more stable.

[0284] For example, when the telescopic leg 2 a is at its longest, the first positioning protrusion 131 abuts against the second positioning protrusion 221 .

[0285] In other examples, the first support member 100 has a first end and a second end. When the telescopic leg 2a is the longest, 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 second end of the first support member 100 .

[0286] In some implementations of the present utility model, referring to Fig.12 , 18 etc., or refer to Fig.81 , 82The number of the first positioning protrusions 131 is 2, the number of the second positioning protrusions 221 is 2, the second positioning member 220 has a second sliding groove 203 adapted to the first body 130, the first body 130 is slidably mounted in 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, and the two second positioning protrusions 221 are located at or close to the two first side edges 203c. The advantage of such a setting is that the first support member 100 is more stable when positioned relative to the second support member 200.

[0287] For example, the two first side edges 203c are located on two opposite sides of the third stretching surface 203a.

[0288] For example, the first body 130 has a first end and a second end. When the telescopic leg 2 a is the longest, 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 .

[0289] For example, the second support member 200 has a first end and a second end. When the telescopic leg 2 a is the longest, 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 .

[0290] 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 . When the first support member 100 slides relative to the second support member 200 , the first positioning protrusion 131 may slide over the second positioning protrusion 221 .

[0291] 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 .

[0292] In some implementations of the present utility model, referring to Fig.12 , 18 etc., or refer to Fig.81 The first positioning protrusion 131 has two opposite first side walls 131a. From the bottom end to the top end of the first positioning protrusion 131, the distance between the two first side walls 131a is narrowed. The first side wall 131a can abut against the second positioning protrusion 221. When the first positioning protrusion 131 slides over the second positioning protrusion 221, the first side wall 131a is in sliding contact with the second positioning protrusion 221, and the top end of the first positioning protrusion 131 is in sliding contact with the second positioning protrusion 221. The advantage of this arrangement is that when the first positioning protrusion 131 slides over the second positioning protrusion 221, it is not easy to cause wear on the first positioning protrusion 131 and the second positioning protrusion 221.

[0293] For example, the first side wall 131a and the top of the first positioning protrusion 131 are in a gradual transition, for example, the first side wall 131a and the top of the first positioning protrusion 131 are in a smooth curved surface transition, and for another example, the first side wall 131a and the top of the first positioning protrusion 131 are in a bevel transition.

[0294] It can be understood that when the telescopic support leg 2 a is in the supporting state, one of the first side walls 131 a of the first positioning protrusion 131 abuts against the second positioning protrusion 221 .

[0295] In some other implementations of the present invention, refer to Fig.12 , 18 etc., or refer to Fig.82 The second positioning protrusion 221 has two opposite second side walls 205. From the bottom end to the top end of the second positioning protrusion 221, the distance between the two second side walls 205 is narrowed. The first positioning protrusion 131 can be against the second side wall 205. When the first positioning protrusion 131 slides over the second positioning protrusion 221, the first positioning protrusion 131 is in sliding contact with the second side wall 205, and the first positioning protrusion 131 is in sliding contact with the top end of the second positioning protrusion 221. The advantage of this arrangement is that when the first positioning protrusion 131 slides over the second positioning protrusion 221, it is not easy to cause wear on the first positioning protrusion 131 and the second positioning protrusion 221.

[0296] For example, the second side wall 205 and the top of the second positioning protrusion 221 are gradually transitioned, for example, the second side wall 205 and the top of the second positioning protrusion 221 are smoothly curved, and for another example, the second side wall 205 and the top of the second positioning protrusion 221 are inclined.

[0297] It can be understood 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 side walls 205 of the second positioning protrusion 221 .

[0298] In some implementations of the present utility model, referring to Fig.17 Etc., or referring to the figure, the first sliding part 140 is provided with a first limiting wall 102, the second positioning member 220 has 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 are butted against each other, and the first positioning protrusion 131 is close to the first limiting wall 102. The advantage of such a setting is that the telescopic leg 2a can be quickly stretched to the longest length, and when the length is the longest (or close to the longest length), the first positioning protrusion 131 and the second positioning protrusion 221 are butted against each other, so that the telescopic leg 2a is more stable when supported.

[0299] For example, when the telescopic leg 2 a is at its longest, the first positioning protrusion 131 abuts against the second positioning protrusion 221 .

[0300] For example, when the telescopic leg 2 a is at its longest length, there is a gap between the first positioning protrusion 131 and the second positioning protrusion 221 . When the telescopic leg 2 a is at its longest length, the first support member 100 can slide a short distance to abut against the second positioning protrusion 221 .

[0301] The first sliding groove 201 is a columnar groove, 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 , the second sliding groove 203 is a columnar groove, and the first body 130 is circumferentially fixed relative to the second sliding groove 203 .

[0302] In some implementations of the present utility model, referring to Figure 5 The first support member 100 includes a first body 130 and a first sliding portion 140 disposed on the first body 130, the second positioning member 220 is provided with a second sliding groove 203, and the first body 130 is slidably mounted in the second sliding groove 203; the second 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 such a configuration is that two sliding fits are formed between the first support member 100 and the second support member 200, so that the first support member 100 is more stable when sliding relative to the second support member 200.

[0303] 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, and when the telescopic leg 2a is the longest, the first end of the first support member 100 extends from the first end of the second support member 200. The first sliding portion 140 is located at or close to the second end of the first support member 100, and the second positioning member 220 is close to or located at the first end of the second support member 200.

[0304] For example, the second sliding groove 203 is a columnar groove, the first 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 portion 140 is circumferentially fixed relative to the first sliding groove 201 .

[0305] For example, the cross section of the second sliding groove 203 is in a “c” shape, and the cross section of the first body 130 is in a “c” shape.

[0306] For example, the cross section of the second sliding groove 203 is semicircular, elliptical, polygonal, etc., and correspondingly, the cross section of the first body 130 is semicircular, elliptical, polygonal, etc.

[0307] In other examples, the second sliding groove 203 is a columnar groove with any other cross-sectional shape, such as a cylindrical groove, and correspondingly, the first main body 130 is a columnar body with any other cross-sectional shape, such as a cylinder.

[0308] In other examples, the first body 130 is coaxially rotatable relative to the second sliding slot 203 .

[0309] In some implementations of the present utility model, referring to Fig.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 over the third positioning protrusion 132. The second support member 200 has a second positioning protrusion 221. When the telescopic leg 2a is in a retracted state, the third positioning protrusion 132 abuts against the second positioning protrusion 221 to prevent the first support member 100 from sliding out of the second support member 200. The advantage of such a configuration is that when the first support member 100 is stored in the second support member 200, the first support member 100 can be kept in the second support member 200, thereby preventing the first support member 100 from sliding relative to the second support member 200, thereby affecting the storage of the telescopic leg 2a.

[0310] For example, the third positioning protrusion 132 is protruded from the first support member 100 , or the third positioning protrusion 132 is a side wall of a groove of the first support member 100 .

[0311] By way of example, the second positioning protrusion 221 is protruded from the first support member 100 , or the third positioning protrusion 132 is a side wall of a groove of the first support member 100 .

[0312] For example, the number of the third positioning protrusions 132 may be 1, 2, 3, etc., and the number of the second positioning protrusions 221 may be 1, 2, 3, etc.

[0313] For example, when the third positioning protrusion 132 abuts against the second positioning protrusion 221 , an additional retaining force is provided for the first support member 100 to be received in the second support member 200 , thereby preventing the first support member 100 from sliding out of the second support member 200 .

[0314] For example, the third positioning protrusion 132 sliding over the second positioning protrusion 221 may mean that when the telescopic leg 2a is in the retracted state, the third positioning protrusion 132 is abutted against the second positioning protrusion 221, and when the pulling force applied to the telescopic leg 2a is large enough, the third positioning protrusion 132 slides over the second positioning protrusion 221, so that the first support member 100 can be extended from the second support member 200.

[0315] For example, the third positioning protrusion 132 sliding over the second positioning protrusion 221 can also mean that, when the telescopic bracket is in the supporting state, the third positioning protrusion 132 and the second positioning protrusion 221 do not abut against each other, and when the pressure applied to the telescopic leg 2a is large enough, the first support member 100 is retracted relative to the second support member 200, and the third positioning protrusion 132 slides over the second positioning protrusion 221. After the third positioning protrusion 132 slides over the second positioning protrusion 221, the third positioning protrusion 132 can abut against the second positioning protrusion 221, so that the first support member 100 is maintained on the second support member 200 when the telescopic leg 2a is in the retracted state.

[0316] For example, in one implementation, the telescopic leg 2 a achieves the accommodation of the first support member 100 in the second support member 200 through the cooperation between the third positioning protrusion 132 and the second positioning protrusion 221 .

[0317] It is understandable that, when the third positioning protrusion 132 slides over the second positioning protrusion 221 , the third positioning protrusion 132 is deformed and / or the second positioning protrusion 221 is deformed, so that the third positioning protrusion 132 can slide over the second positioning protrusion 221 .

[0318] In some implementations of the present utility model, referring to Fig.18 The second support member 200 includes a second main body 210 and a second positioning member 220. The second positioning member 220 is arranged on the second main body 210. The second positioning member 220 is located between the first support member 100 and the second main body 210. The second positioning protrusion 221 is arranged on the second positioning member 220. The first support member 100 is slidably installed on the second positioning member 220 so that the first support member 100 can slide relative to the second support member 200. The first support member 100 is sleeved on the second main body 210.

[0319] For example, the first support member 100 is slidably mounted on the second positioning member 220 .

[0320] For example, the second positioning member 220 is in the shape of a thin sheet, and the second positioning member 220 surrounds or partially surrounds the first supporting member 100 .

[0321] For example, the second positioning member 220 surrounds to form the second sliding groove 203 , the first supporting member 100 is slidably sleeved in the second sliding groove 203 , and the first sliding groove 201 and the second sliding groove 203 are coaxial or extend in the same direction.

[0322] For example, the second sliding groove 203 is a columnar groove, and the first support member 100 is circumferentially fixed around the second sliding groove 203 .

[0323] For example, the second positioning member 220 has a third stretching surface 203a and a fourth stretching surface 203b opposite to each other, and the third stretching surface 203a and the fourth stretching surface 203b work together to restrict the first support member 100 in the second sliding groove 203. For example, the second positioning protrusion 221 is protruding from the fourth stretching surface 203b.

[0324] For example, the second positioning member 220 is fixedly mounted on the second body 210 , and the second positioning member 220 is detachable relative to the second body 210 .

[0325] 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 .

[0326] For example, the second positioning member 220 is in the shape of a thin sheet with a second opening 204 . When the second positioning member 220 is installed into the first sliding groove 201 , the second positioning member 220 is squeezed and deformed as a whole, so that the second positioning member 220 is easily installed into the first sliding groove 201 .

[0327] For example, the second positioning member 220 is in the shape of a thin sheet having a second opening 204, and the second opening 204 passes through the outer wall of the second positioning member 220 to the fourth stretching surface 203b. When the second positioning member 220 needs to be removed, the second positioning member 220 is compressed to shrink the second opening 204, so that the second positioning member 220 can be removed from the second body 210.

[0328] In other examples, the second positioning protrusion 221 is disposed on the second body 210 .

[0329] In some implementations of the present utility model, referring to Fig. 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 leg 2a is the 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 such a configuration is that the first support member 100 is prevented from being excessively received in the second support member 200.

[0330] For example, the third limiting wall 104 is located at or close to the first end of the first support member 100 . More specifically, the third limiting wall 104 is close to or located at the first end of the first body 130 .

[0331] For example, the outer wall of the first body 130 is slidably mounted on the second positioning member 220 , and the third limiting wall 104 and the outer wall of the first body 130 form a step.

[0332] By way of example, the fourth limiting wall 206 is located at one end of the second positioning member 220 .

[0333] For example, the first body 130 has a first end and a second end. When the length of the telescopic leg 2a is the longest, 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, which covers the first end of the first body 130, and the fourth limiting wall 206 is arranged on the rim 222.

[0334] In some implementations of the present utility model, referring to Fig.11 , 18 The number of the third positioning protrusions 132 is 2, the number of the second positioning protrusions 221 is 2, the second positioning member 220 has a second sliding groove 203 adapted to the first body 130, the first body 130 is slidably mounted in 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, and the two second positioning protrusions 221 are located at or close to the two first side edges 203c. The advantage of such a setting is that the first support member 100 is more stable when it is against the third positioning protrusion 132.

[0335] For example, two second positioning protrusions 221 are provided on the fourth stretching surface 203 b.

[0336] In some implementations of the present utility model, referring to Fig.11 , 18 The first support member 100 has a first end and a second end. When the telescopic leg 2a is at its longest, 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 first end of the first support member 100. The advantage of such a configuration is that when the telescopic leg 2a is stored to a shorter length, the first support member 100 and the third positioning protrusion 132 abut against each other.

[0337] For example, when the length of the telescopic leg 2 a is the shortest, the third positioning protrusion 132 abuts against the second positioning protrusion 221 .

[0338] In some implementations of the present utility model, referring to Fig.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 .

[0339] The first support member 100 can be sleeved on the second support member 200 in any of the following situations, or a combination of the following situations:

[0340] 1. The first support member 100 is sleeved in the first sliding groove 201 of the second support member 200;

[0341] 2. The first support member 100 is sleeved in the second sliding groove 203 of the second support member 200 .

[0342] The first support member 100 can slide relative to the second support member 200 in any of the following situations, or a combination of the following situations:

[0343] 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 between the first sliding portion 140 and the first sliding groove 201 .

[0344] 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 body 130 and the second sliding groove 203 .

[0345] In some implementations of the present utility model, referring to Fig.11 The third positioning protrusion 132 has two opposite third side walls 132a. From the bottom end to the top end of the third positioning protrusion 132, the distance between the two third side walls 132a is narrowed. The third side wall 132a can abut against the second positioning protrusion 221. In the process of the third positioning protrusion 132 sliding over the second positioning protrusion 221, the third side wall 132a is in sliding contact with the second positioning protrusion 221, and the top end of the third positioning protrusion 132 is in sliding contact with the second positioning protrusion 221.

[0346] For example, the third side wall 132a and the top of the third positioning protrusion 132 are in a gradual transition, for example, the third side wall 132a and the top of the third positioning protrusion 132 are in a smooth curved surface transition, and for another example, the third side wall 132a and the top of the third positioning protrusion 132 are in a bevel transition.

[0347] It can be understood that when the third positioning protrusion 132 abuts against the second positioning protrusion 221 , one of the third side walls 132 a of the third positioning protrusion 132 abuts against the second positioning protrusion 221 .

[0348] In some other implementations of the present utility model, refer to Fig.18 The second positioning protrusion 221 has two opposite second side walls 205, and the distance between the two second side walls 205 is narrowed from the bottom end to the top end of the second positioning protrusion 221. The third positioning protrusion 132 can be against the second side wall 205. In the process of the third positioning protrusion 132 sliding over the second positioning protrusion 221, the third positioning protrusion 132 is in sliding contact with the second side wall 205, and the third positioning protrusion 132 is in sliding contact with the top end of the second positioning protrusion 221.

[0349] For example, the second side wall 205 and the top of the second positioning protrusion 221 are gradually transitioned, for example, the second side wall 205 and the top of the second positioning protrusion 221 are smoothly curved, and for another example, the second side wall 205 and the top of the second positioning protrusion 221 are inclined.

[0350] It can be understood 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 side walls 205 of the second positioning protrusion 221 .

[0351] In some other implementations of the present utility model, refer to Figure 1-27 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, which is not limited to any of the following situations, or a combination of the following situations:

[0352] 1. The first support member does not have a protruding structure, and the first support member is directly damped and matched with the first sliding groove 201. For example, the outer wall of the first sliding portion 140 is directly damped and contacted with the first sliding groove 201 (for example, the first sliding portion 140 is tightly matched with the first sliding groove 201), so that the first support member 100 can be positioned on the second support member 200.

[0353] 2. The first support member 100 has a protruding structure. For example, the first support member 100 has a first damping protrusion 110 that is in damping contact with the first sliding groove 201 , so that the first support member 100 can be positioned on the second support member 200 .

[0354] 3. The first support member does not have a protruding structure, and the first support member 100 is in damping contact with the second sliding groove 203. Specifically, the first main body 130 is in direct damping contact with the second sliding groove 203 (for example, the first main body 130 is tightly fitted with the second sliding groove 203, etc.), so that the first support member 100 can be positioned on the second support member 200.

[0355] 4. Both the first support member 100 and the second support member 200 have a protruding structure. 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 .

[0356] In some implementations of the present utility model, referring to Fig.26The second support member 200 includes a second main body 210 and a rim 222. The second main body 210 is provided with a first sliding groove 201. The first support member 100 can slide relative to the first sliding groove 201. The second main body 210 has a first end and a second end. When the telescopic leg 2a is extended, the first support member 100 extends from the first end of the second main body 210, and the rim 222 covers the first end of the second main body 210. The benefit of the second support member 200 being provided with the rim 222 is that the second support member 200 is more beautiful, and the second main body 210 is the main component of the second support member 200. The rim 222 can cover the burrs or sharp edges that may exist at the first end of the second main body 210, so that the first end of the second main body 210 is not easy to hurt the hand.

[0357] For example, the second body 210 is made by casting or stamping, and the edge 222 is a plastic part.

[0358] For example, the edge 222 completely covers the first end of the second body 210 , or the edge 222 partially covers the first end of the second body 210 .

[0359] For example, the outer side wall of the second body 210 has a first edge 207a, the first edge 207a is located at the first end of the second body 210, and the outer wall of the edge 222 has a second edge 207b, and the second edge 207b is aligned with the first edge 207a. The advantage of such a setting is that the second support member 200 is more beautiful and is not easy to scratch the user's hand. For example, the first edge 207a and the second edge 207b are completely attached or have a gap.

[0360] It can be understood that the alignment of edge A and edge B means that edge A is close to or in contact with edge B, and there is no height difference between edge A and edge B.

[0361] For example, the outer wall of the edge 222 is smoothly transitioned. Along the direction of extension of the telescopic leg 2a, the edge 222 gradually narrows.

[0362] In some implementations of the present utility model, referring to Fig.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, the third limiting wall 104 abuts against the fourth limiting wall 206, and the fourth limiting wall 206 is disposed at the edge 222. The edge 222 is used to cover the second end of the second body 210 and to abut against the third limiting wall 104, so that the structure of the telescopic leg 2a is more compact.

[0363] For example, the fourth limiting wall 206 is opposite to the first retaining wall 208 .

[0364] In some implementations of the present utility model, referring to Figure 1-6 , 26, etc., the multi-legged bracket also includes a first mounting portion 5 provided on the support rod 1, the first support member 100 includes a first main body 130 and a first connecting portion 150, the first main body 130 is sleeved in the second support member 200, the first main body 130 has a first end and a second end, when the telescopic leg 2a is the longest, the first end of the first main body 130 extends from the second support member 200, the first connecting portion 150 is provided on the first main body 130 (for example, the first connecting portion 150 is provided on the first end of the first main 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 can be adjusted; the third limiting wall 104 is provided on the first connecting portion 150. The first connecting portion 150 is used for both rotatably connecting with the first mounting portion 5 and abutting against the edge 222, so that the structure of the telescopic leg 2a is more compact.

[0365] For example, the first mounting portion 5 is integrally or fixedly mounted on the support rod 1 , and the first connecting portion 150 is rotatably mounted on the first mounting portion 5 so that the angle between the telescopic foot 2a and the support rod 1 is adjustable.

[0366] For example, the first mounting portion 5 is slidably mounted on the support rod 1, 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 leg 2a, the telescopic leg 2a, the first mounting portion 5, the support rod 1, and the first connecting rod 7 form a slider connecting rod mechanism, and during the sliding process of the first mounting portion 5 relative to the support rod 1, the angle between the telescopic leg 2a and the support rod 1 changes.

[0367] In some implementations of the present utility model, referring to Fig.26 The second positioning member 220 has a rim 222. The advantage of such a configuration is that the second positioning member 220 is used for both being slidably connected with the first supporting member 100 and covering the first end of the second body 210, so that the structure of the telescopic leg 2a is more compact.

[0368] 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 edge 222 is located at the first end of the second positioning member 220 .

[0369] In some implementations of the present invention, the first body has a first end and a second end. When the length of the telescopic leg is the longest, the first end of the first body extends from the second support member, and when the length of the telescopic leg is the shortest, the first end of the first body is received in the second support member.

[0370] For example, the first end of the first body is received in the second positioning member or the second body.

[0371] In some implementations of the present utility model, referring to Figure 5 ,14 The first body 130 is slidably mounted on the second positioning member 220 so that the first support member 100 can slide relative to the second support member 200; when the telescopic support leg 2a is the shortest, the first end of the first body 130 is received in the second positioning member 220. The advantage of such a configuration is that the structure of the telescopic support leg 2a is more compact and more beautiful.

[0372] In some implementations of the present utility model, referring to 11, 12, etc., the second body 210 is provided with a first sliding groove 201, the second positioning member 220 can be inserted into the first sliding groove 201 through the first end of the second body 210, and the edge 222 has a first retaining wall 208, and the first retaining wall 208 abuts against the first end of the second body 210 to limit the movement of the second positioning member 220 along the first direction, and the first direction is the direction in which the second positioning member 220 is inserted into the first sliding groove 201. The advantage of such a setting is that, on the one hand, the second positioning member 220 is easy to install, and on the other hand, the edge 222 also has the function of limiting the second positioning member 220, so that the structure of the telescopic support leg 2a is more compact.

[0373] It can be understood that the edge 222 has a covering wall covering the first end of the second body 210 , and the first retaining wall 208 is a part or the whole of the covering wall.

[0374] For example, the second retaining wall and the outer side wall of the second positioning member 220 form a step.

[0375] It can be understood that when the first support member 100 is retracted into the second support member 200 , the first retaining wall 208 abuts against the first end of the second body 210 to limit the movement of the second positioning member 220 along the first direction.

[0376] For example, the second positioning member 220 is provided with a first limiting portion 223, and 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 portion 223 cooperates with the second limiting portion 2019 to limit the second positioning member 220 in the first sliding groove 201.

[0377] The second limiting portion 2019 is a groove, the first limiting portion 223 is a protrusion, the first limiting portion 223 is provided with a first sliding surface 209, and when the second positioning member 220 is inserted into the first sliding groove 201, the first sliding surface 209 slides over the second body 210, or, the first limiting portion 223 is a groove, the second limiting portion 2019 is a protrusion, the second limiting portion 2019 is provided with a second sliding surface, and when the second positioning member 220 is inserted into the first sliding groove 201, the first sliding surface 209 slides over the second positioning member 220.

[0378] In some implementations of the present invention, the second positioning member 220 can position the first supporting member 100 on the second supporting member 200 .

[0379] 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 .

[0380] For example, the second positioning member 220 is provided with a second positioning protrusion 221 , the first body 130 is provided with a first positioning protrusion 131 , and 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 .

[0381] In some implementations of the present utility model, referring to Figure 5 , 14 The second support member 200 has a second sliding groove 203 adapted to the first body 130, and the first body 130 is slidably mounted in the second sliding groove 203 so that the first support member 100 can slide relative to the second support member 200; the first body 130 has a first end and a second end, and when the length of the telescopic leg 2a is the longest, the first end of the first body 130 extends from the second support member 200, and when the length of the telescopic leg 2a is the shortest, the first end of the first body 130 is received in the second sliding groove 203. The advantage of such a setting is that after the telescopic leg 2a is received, the structure is more compact and more beautiful.

[0382] For example, the second support member 200 includes a second body 210 and a second positioning member 220 disposed on the second body 210 ; the second sliding groove 203 is disposed on the second positioning member 220 ; and the second positioning member 220 can position the first support member 100 on the second support member 200 .

[0383] For example, when the telescopic leg 2 a is at its shortest, the second positioning member 220 abuts against the third limiting wall 104 .

[0384] In some implementations of the present invention, referring to 22 and the like, when the telescopic leg 2a is at its shortest, the second support member 200 abuts against the first connection portion 150. This arrangement has the advantage of making the structure of the telescopic leg 2a more compact.

[0385] In some implementations of the present invention, when the telescopic leg 2a is at its shortest, the outer side wall of the second support member 200 is aligned with the outer side wall of the first connecting portion 150. This arrangement has the advantage of making the structure of the telescopic leg 2a more compact after being stored.

[0386] It can be understood that the alignment of the wall surface of A with the wall surface of B means that the edge of the wall surface of A is close to or fits the edge of the wall surface of B, and no height difference (ie, no step) is formed at the connection or proximity.

[0387] In some implementations of the present invention, when the telescopic leg 2a and the support rod 1 have a first angle, the outer wall of the first connecting portion 150 is aligned with the outer wall of the first mounting portion 5. The advantage of this arrangement is that the structure of the telescopic leg 2a is more compact and beautiful after being stored.

[0388] In some implementations of the present utility model, referring to Fig.19 After the first support member 100 is received in the second support member 200 , at least three legs 2 can be folded together to form a first columnar structure.

[0389] For example, the first columnar structure can be handheld, so that the power-consuming body 3 can be used in a handheld state.

[0390] In some implementations of the present utility model, referring to Fig.19 The first mounting portion 5 is a second columnar structure, and after the first support member 100 is stored 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 of the telescopic support leg 2a is more compact and beautiful after being stored.

[0391] In some implementations of the present invention, the outer wall of the edge 222 is aligned with the outer wall of the second body 210; when the telescopic leg 2a is shortest, the first connecting portion 150 abuts against the edge 222. The advantage of this arrangement is that the structure of the telescopic leg 2a is more compact and beautiful after being stored.

[0392] In some implementations of the present utility model, referring to Figure 1-6, 18-24, etc., the multi-legged 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; the first support member 100 is slidable relative to the first sliding groove 201, and the first support member 100 can be positioned in the first sliding groove 201; the second support member 200 is provided with a first avoidance opening 2010 connected to 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 avoidance 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 avoidance opening 2010 serves as an opening for avoiding the first connecting rod 7; during the sliding process of the first mounting portion 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 connecting rod 7 is rotatably connected to the first support member 100, making the structure of the multi-legged bracket more compact, and the arrangement of the first avoidance opening 2010 ensures that the first connecting rod 7 does not affect the sliding of the first support member 100 relative to the second support member 200.

[0393] For example, the first end of the first connecting rod 7 is a rotation axis, and a corresponding connection position of the first support member is provided with a rotation hole, or the first end of the first connecting rod 7 is a rotation hole, and a corresponding position of the first support member is provided with a rotation axis.

[0394] For example, the second end of the first connecting rod 7 is a rotation axis, and the corresponding connection point of the support rod is a rotation hole, or the second end of the first connecting rod 7 is a rotation hole, and the corresponding connection point of the support rod is a rotation axis.

[0395] 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 cooperating with the first sliding groove 201 , or by the first support member 100 slidingly cooperating with the second sliding groove 203 .

[0396] Exemplarily, during the extension and retraction process of the telescopic leg, the first end of the first connecting rod 7 is always located in the first sliding groove.

[0397] In some implementations of the present utility model, referring to Figure 18-24 , the telescopic support leg 2a can be stored in the support rod 1, and after the telescopic support leg 2a is stored in 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 the structure of the multi-legged bracket is more compact.

[0398] For example, the telescopic leg 2a has a second accommodating space 2017, and after the telescopic leg 2a is received in the support rod 1, the first connecting rod 7 is received in the second accommodating space 2017. More specifically, after the first supporting member 100 of the telescopic leg 2a is received in the corresponding second supporting member 200, and the telescopic leg 2a is received in the support rod 1, the first connecting rod 7 is received in the second accommodating space 2017, and in the process of the telescopic leg 2a receiving the support rod 1, the first connecting rod 7 is received in the second accommodating space 2017 through the first avoidance opening 2010.

[0399] In some implementations of the present utility model, referring to Fig. 22 When the telescopic leg 2 a is at its shortest, the second supporting member 200 abuts against the first connecting portion 150 .

[0400] In some implementations of the present utility model, referring to Fig.23 The first support member 100 has a first projection plane perpendicular to the sliding direction thereof, and the projection of the first sliding portion 140 on the first projection plane includes 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 portion 140. The advantage of such a configuration is that the first connecting rod 7 is connected to the "thicker" first sliding portion 140, so that the telescopic support leg 2a is not easily damaged, and the structure of the multi-legged bracket is more compact.

[0401] In some implementations of the present utility model, referring to Fig.23 The first sliding part 140 is provided with a first rotating cavity 107, a first rotating shaft 160 is provided in the first rotating cavity 107, a first end of the first connecting rod 7 is provided with a first rotating connector 7a, the first rotating connector 7a is rotatably matched with the first rotating shaft 160, the projection of the first sliding part 140 on the first projection plane includes 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 includes 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 includes the projection of the first rotating cavity 107 on the first projection plane. The advantage of such an arrangement is that the structure of the multi-legged bracket is more compact.

[0402] For example, the second end of the first connecting rod 7 has a second rotating connector 7b, the supporting rod 1 has a second rotating cavity 1001, a second rotating shaft 1c is arranged in the second rotating cavity 1001, and the second rotating connector 7b is rotatably matched with the second rotating shaft 1c.

[0404] For example, the telescopic support foot 2 a is connected to the support rod 1 only through the first connecting rod 7 .

[0405] For example, the telescopic support leg 2a is directly connected to the support rod 1, or the telescopic support leg 2a is connected to the support rod 1 through an intermediate piece.

[0407] For example, the first connecting rod 7 , the supporting rod 1 , and the telescopic supporting legs 2 a are directly connected (movably connected or fixedly connected) to each other, so as to form a stable triangular structure to support the electrical main body 3 .

[0408] For example, the first connecting rod 7 is fixed relative to the supporting rod 1 , and the first connecting rod 7 is fixed relative to the first supporting member 100 .

[0409] In some implementations of the present utility model, 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;

[0420] For example, the second opening 204 of the second positioning member 220 passes through the fourth stretching surface 203 b.

[0421] In some implementations of the present utility model, referring to Fig. 9 , 15The first support member 100 has a first damping protrusion 110 , and the first damping protrusion 110 is in 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 supporting foot 2a is in a supporting state.

The advantage of such a setting is that, on the one hand, the second positioning member 220 is easy to install, and on the other hand, when the first support member 100 slides relative to the second support member 200, the second positioning member 220 is prevented from falling off.

[0426] For example, the second limiting portion 2019 is a groove, the first limiting portion 223 is a protrusion, the first limiting portion 223 is provided with a first sliding surface 209, and in the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides over the second body 210, or the first limiting portion 223 is a groove, the second limiting portion 2019 is a protrusion, the second limiting portion 2019 is provided with a second sliding surface, and in the process of the second positioning member 220 being inserted into the first sliding groove 201, the first sliding surface 209 slides over the second positioning member 220. The advantage of such a configuration is that the second positioning member 220 is easy to install.

[0427] For example, the second positioning member 220 is detachably mounted on the inner wall of the first sliding groove 201. The second positioning member 220 is in the form of a thin sheet having a second opening 204 therethrough. The second positioning member 220 can be removed from the first sliding groove 201 by squeezing it. When the second positioning member 220 is squeezed, the second opening 204 is deformed.

[0428] For example, the second positioning member 220 is cylindrical and 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.

[0429] By way of example, the second opening 204 extends along an extending direction of the first sliding slot 201 .

[0430] For example, the position of the second opening 204 corresponds to the first avoidance opening 2010 of the first sliding slot 201 .

[0431] In some implementations of the present utility model, referring to Figure 6 , 24 The multi-legged bracket further comprises a first mounting portion 5 and at least one first connecting rod 7, wherein at least one first connecting rod 7 corresponds to at least one telescopic leg 2a; the first mounting portion 5 is slidably mounted on the support rod 1; the telescopic leg 2a is rotatably connected to the first mounting portion 5; the support rod 1 comprises a support body 1a and a connecting column 1b, wherein 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 process of the first mounting portion 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-legged bracket more compact.

[0432] For example, the multi-legged bracket further includes a first fastener 1c, which is used to fasten the connecting column 1b to the supporting body 1a. The first fastener 1c radially passes through the outer wall of the supporting body and is fastened to the connecting column 1b in the connecting groove 1002.

[0433] For example, the connection column 1 b is clamped and connected with the connection groove 1002 , so that the connection column 1 b is installed on the support body 1 a .

[0434] For example, the connection column 1 b is interference-fitted with the connection groove 1002 , so that the connection column 1 b is installed on the support body 1 a .

[0435] In some implementations of the present invention, reference is made to Figure 6 , 24 The second support member 200 of the telescopic support leg 2a further includes a foot pad 240, which is installed at one end of the second support member. When the multi-legged bracket is supported on a support surface, the foot pad 240 contacts the support surface.

[0436] For example, the foot pad 240 is detachably mounted on the second body of the second support member 200 .

[0437] For example, the foot pad 240 is made of soft materials such as rubber and plastic.

[0438] For example, the foot pad 240 includes a mounting member 241 and an anti-slip cover 242. The mounting member 241 is detachably mounted on the second body of the second support member 200. The mounting member 241 facilitates the installation of the anti-slip cover 242, and the anti-slip cover 242 covers the mounting member 241. For example, the mounting member 241 can be fastened to the second body by a fastener.

[0439] In some other implementations of the present invention, refer to Figure 3 The second support member 200 of the telescopic support leg 2a is rotatably connected to the first mounting portion 5, and the first connecting rod 7 is rotatably connected to the second support member 200. When the first mounting portion 5 slides relative to the support rod 1, the angle between the telescopic support leg 2a and the support rod 1 changes. For example, when the multi-legged bracket is supported on a support surface, the first support member 100 extends from the second support member 200, and the first support member 100 contacts the support surface.

[0440] In some implementations of the present utility model, referring to Figure 26 to Figure 26h , or refer to Figures 83 to 90 The first connecting portion 150 is protruded from the first main body 130 . The advantage of such a configuration is that the structural strength of the rotational connection between the first supporting member 100 and the first mounting portion 5 is enhanced.

[0441] For example, the first connection portion 150 has a third limiting wall 132a. When the telescopic leg 2a is shortest, the second support member 200 abuts against the third limiting wall 132a. The third limiting wall 132a is disposed on the first connection portion 150 to make the telescopic leg 2a more compact.

[0442] For example, the first body 130 is provided with a fifth limiting wall 105, and when the telescopic leg 2a is at its shortest, the second support member 200 abuts against the fifth limiting wall 105. The advantage of such a configuration is that the second support member 200 is prevented from being accommodated in the first support member 100 in a transitional manner.

[0443] For example, the third limiting wall 132a is located on the outer side of the first support member 100, and the fifth limiting wall 105 is located on the inner side of the first support member 100. The advantage of such an arrangement is that the telescopic support leg 2a is more stable when it is kept in the shortest state.

[0444] Exemplarily, 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 such a configuration is that the structure of the telescopic support leg 2a is more stable when it is kept in the shortest state.

[0445] Exemplarily, 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 the two fifth limiting sub-walls 105a are respectively close to the third sliding body 130a and the fourth sliding body 130b. The advantage of such a configuration is that, on the one hand, the structure of the telescopic leg 2a is more stable when maintained in the shortest state, and on the other hand, the structure of the telescopic leg 2a is more compact. Furthermore, the configuration of the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032 makes the telescopic leg 2a more stable in its telescopic operation.

[0446] For example, the two first positioning protrusions 131 are respectively provided on the third sliding body 130a and the fourth sliding body 130b, and the two second positioning protrusions 132 are respectively provided on the third sliding body 130a and the fourth sliding body 130b.

[0447] For example, the third sliding body 130a and the fourth sliding body 130b are respectively located on opposite sides of the first body 130. The advantage of such a configuration is that, on the one hand, the structure of the telescopic leg 2a is more stable when it is kept in the shortest state, and on the other hand, the structure of the telescopic leg 2a is more compact. On the other hand, the third sliding body 130a and the fourth sliding body 130b are respectively located on both sides of the first body 130, so that the telescopic leg 2a is more stable in telescoping.

[0448] By way of example, the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032 are respectively located at two opposite sides of the second sliding groove 203 , the third sliding sub-groove 2031 is a groove with an opening, and the fourth sliding sub-groove 2032 is a groove with an opening.

[0449] For example, the second support member 200 has a first shell 251 and a second shell 252, the third sliding sub-groove 2031 is located in the space surrounded by the first shell 251, and the fourth sliding sub-groove 2032 is located in the space surrounded by the second shell 252. When the length of the telescopic leg is the shortest, the two fifth limiting sub-walls 105a are respectively against the end of the first shell 251 and the end of the second shell 252.

[0450] The advantage of such a configuration is that, on the one hand, the structure of the telescopic leg 2a is more stable when maintained in the shortest state; on the other hand, the first shell 251 accommodates the third sliding sub-groove 2031 and abuts against the fifth limiting sub-wall 105a, and the second shell 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.

[0451] For example, the first enclosure 251 has a first sealing plate 251 a , which is used to partially close the opening of the third sliding sub-groove 2031 , and the first sealing plate 251 a is used to further seal the third sliding body 130 a in the third sliding sub-groove 2031 .

[0452] For example, the second enclosure 252 has a second sealing plate 252 a , and the second sealing plate 252 a is used to partially close the fourth sliding sub-groove 2032 . The second sealing plate 252 a is used to seal the fourth sliding body 130 b in the fourth sliding sub-groove 2032 .

[0453] For example, when the length of the telescopic legs is the shortest, the two fifth limiting sub-walls 105a respectively abut against the ends of the first sealing plate 251a and the second sealing plate 252a.

[0454] For example, the first sealing plate 251 a and the second sealing plate 252 a are respectively located on two opposite sides of the first avoidance opening 2010 .

[0455] For example, when the telescopic leg 2a is at its shortest, the first body 130 is accommodated in the second support member 200, and the fifth limiting wall 105 is accommodated in the second support member 200. The advantage of such an arrangement is that the structure of the telescopic leg 2a is more compact.

[0456] For example, the three telescopic legs 2a can be stored to form a first columnar structure. After the three telescopic legs 2a are stored to form the first columnar structure, the first connecting rod 7 is stored in the second accommodating space 2017 of the telescopic legs 2a through the first avoidance opening 2010. The advantage of this arrangement is that after the telescopic legs 2a are stored in the support rod 1, the structure of the multi-legged bracket is more compact.

[0457] In some implementations of the present utility model, the first support member 100 includes a first main body 130 and a first connecting portion 150 provided on the first main body 130, the first main body 130 is sleeved on the second support member 200, the first main body 130 can slide relative to the second support member 200 to change the length of the telescopic leg 2a, and 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-legged bracket also includes a first mounting portion 5 provided 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 can be adjusted; the first connecting portion 150 is convexly provided on the first main body 130. The advantage of such a configuration is that the structural strength of the rotational connection between the first support member 100 and the first mounting portion 5 is enhanced.

[0458] In some implementations of the utility model, the first support member 100 has a first connection 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 can be adjusted; the first connection portion 150 of the first support member 100 has a third limiting wall 132a, and when the length of the telescopic leg 2a is the shortest, the second support member 200 and the third limiting wall 132a are against each other. The advantage of such a setting is that, on the one hand, it avoids the first support member 100 from being transiently stored in the second support member 200, and on the other hand, the third limiting wall 132a is arranged on the first connection wall to make the structure of the telescopic leg 2a more compact.

[0459] In some implementations of the embodiment of the utility model, the three legs 2 can be received in the support rod 1. After the three legs 2 are received in the support rod 1, the first mounting portion 5 and the three legs 2 form a columnar structure as a whole.

[0460] For example, the first support member 100 is provided with a fifth limiting wall 105 , and when the length of the telescopic leg 2 a is the shortest, the second support member 200 abuts against the fifth limiting wall 105 .

[0461] For example, the fifth limiting wall 105 is located inside the first supporting member 100. The advantages of such a configuration are, on the one hand, avoiding the first supporting member 100 from being transiently received in the second supporting member 200, and on the other hand, making the structure of the telescopic support leg 2a more compact.

[0462] 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 the fifth limiting wall 105 includes two fifth limiting sub-walls 105a, and the two fifth limiting sub-walls 105a are respectively close to the third sliding body 130a and the fourth sliding body 130b. The advantage of such a configuration is that, on the one hand, the structure of the telescopic leg 2a is more stable when maintained in the shortest state; on the other hand, the two fifth limiting sub-walls 105a are respectively close to the third sliding body 130a and the fourth sliding body 130b, which makes the structure of the telescopic leg 2a more compact; on still another hand, the configuration of the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032 makes the telescopic leg 2a more stable in its extension and retraction.

[0463] For example, the first support member 100 is provided with a first reinforcing rib 261, and the 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 first hand, the fifth limiting wall 105 is provided on the first reinforcing rib 261 to make the structure of the telescopic leg 2a more compact.

[0464] For example, when the telescopic leg 2a is at its shortest, the first body 130 is accommodated in the second support member 200, and the first reinforcing rib 261 is accommodated in the second support member 200. The advantage of such an arrangement is that the telescopic leg 2a has a more compact structure in the stored state.

[0465] For example, at least three legs are telescopic legs 2a; the multi-legged bracket also includes at least three first connecting rods 7; the first mounting portion 5 is slidable relative to the support rod 1; the at least three first connecting rods 7 correspond to the 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, and the first support member 100 is slidable relative to the first sliding groove 201; the second support member 200 is provided with a first avoidance opening 2010 connected to 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, and 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 avoidance opening 2010 serves as an opening for avoiding the corresponding first connecting rod 7; during the sliding process of the first mounting portion 5 along the support rod 1, the telescopic leg 2a is opened or stored relative to the support rod 1; after the first support member 100 of each telescopic leg 2a is stored in the corresponding second support member 200, at least three telescopic legs 2a can be stored in the support rod 1 to form a first columnar structure, and during the process of the three telescopic legs 2a being stored to form the first columnar structure, the first connecting rod 7 is stored in the second accommodating space 2017 of the telescopic leg 2a through the first avoidance opening 2010. On the one hand, the first connecting rod 7 is rotatably connected to the first supporting member 100 of the telescopic leg 2a, making the structure of the telescopic leg 2a more compact. On the other hand, the second supporting member 200 is provided with a first avoidance opening 2010 for avoiding the first connecting rod 7, thereby preventing the first connecting rod 7 from hindering the extension and retraction of the telescopic leg 2a. On the other hand, the telescopic leg 2a has a second accommodating space 2017 for accommodating the first connecting rod 7 after being stored, thereby making the structure of the telescopic leg 2a compact after being stored and occupying a small volume.

[0466] In some implementations of the present utility model, the first support member 100 includes a first body 130, the first body 130 has a first end and a second end, when the length of the telescopic leg 2a is the longest, the first end of the first body 130 extends from the second support member 200, and when the length of the telescopic leg 2a is the shortest, the first end of the first body 130 is received in the second support member 200. The advantage of such a configuration is that the structure of the telescopic leg 2a is more compact in the retracted state.

[0467] For example, the first support member 100 also includes a first connecting portion 150 provided on the first body 130, the first connecting portion 150 is provided at the first end of the first body 130, and 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 can be adjusted.

[0468] For example, when the telescopic leg 2a is shortest, the first connection portion 150 abuts against the second support member 200. The advantage of this arrangement is that the first connection portion 150 is used for both rotational connection with the first mounting portion 5 and abutting against the second support member 200, making the structure of the telescopic leg 2a compact.

[0469] In some implementations of the present utility model, the first support member 100 is slidably mounted 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 mounted in the first sliding sub-groove 201d, and the second sliding body 142 is slidably mounted 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 providing the first sliding sub-groove 201d and the second sliding sub-groove 201e is that the first support member 100 is more stable when sliding relative to the second support member 200.

[0470] For example, the first sliding body 141 and the second sliding body 142 are respectively located on two opposite sides of the first support member 100. The advantage of such an arrangement is that the structure of the telescopic support leg 2a is more compact.

[0471] For example, the second support member 200 has a third sliding sub-groove 2031 and a fourth sliding sub-groove 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-groove 2031 and the fourth sliding sub-groove 2032, the third sliding body 130a is slidably mounted in the third sliding sub-groove 2031, and the fourth sliding body 130b is slidably mounted in the fourth sliding sub-groove 2032. The advantage of such a configuration is that the first support member 100 is more stable when sliding relative to the second support member 200.

[0472] For example, the third sliding body 130a and the fourth sliding body 130b are respectively located on two opposite sides of the first support member 100. The advantage of such an arrangement is that the structure of the telescopic support leg 2a is more compact.

[0473] For example, the first sliding sub-groove 201d is coaxial with the third sliding sub-groove 2031, the second sliding sub-groove 201e is coaxial with the fourth sliding sub-groove 2032, the cross-section of the third sliding sub-groove 2031 is smaller than the cross-section of the first sliding sub-groove 201d, the cross-section of the fourth sliding sub-groove 2032 is smaller than the cross-section of the second sliding sub-groove 201e, and the first support member 100 is non-detachably mounted on the second support member 200.

[0474] For example, the multi-legged bracket further 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, and the second support member 200 is provided with a first avoidance opening 2010, and the first avoidance opening 2010 is located between the first sliding sub-groove 201d and the second sliding sub-groove 201e; the first end of the first connecting rod 7 is rotatably connected to the first supporting portion 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, and when the first supporting portion 100 slides relative to the second supporting portion 200 of the telescopic leg 2a, the first avoidance opening 2010 serves as an opening for avoiding the corresponding first connecting rod 7; during the sliding process of the first mounting portion 5 along the support rod 1, the telescopic leg 2a is stored or opened relative to the support rod 1. The first avoidance opening 2010 is provided between the first sliding sub-groove 201d and the second sliding sub-groove 201e, so that the structure of the telescopic leg 2a is more compact.

[0475] For example, the first sliding sub-groove 201d is formed by being surrounded by the first enclosure 251, the second sliding sub-groove 201e is formed by being surrounded by the second enclosure 252, and the first avoidance opening 2010 is located between the first enclosure 251 and the second enclosure 252. The advantage of such a configuration is that the structure of the telescopic support leg 2a is more compact.

[0476] For example, the first support member 100 has a first guide wall 271 and a second guide wall 272, wherein the first guide wall 271 is close to or in close proximity to the first enclosure 251, and the second guide wall 272 is close to or in close proximity to the second enclosure 252; when the first support member 100 slides relative to the second support member 200, the first avoidance opening 2010 serves as an opening for avoiding the first guide wall 271 and the second guide wall 272. The benefit of providing the first guide wall 271 and the second guide wall 272 is that the first support member 100 is more stable when sliding relative to the second support member 200.

[0477] For example, the first guide wall 271 is close to or close to the first sealing plate 251a, and the second guide wall 272 is close to or close to the second sealing plate 252a.

[0478] For example, the first support member 100 has a second reinforcing rib 262, the first guide wall 271 is located at the end of the second reinforcing rib 262, the second guide wall 272 is located at the end of the second reinforcing rib 262, and the first avoidance opening 2010 is used as an opening for avoiding the second reinforcing rib 262. The advantage of such a configuration is that, on the one hand, the second reinforcing rib 262 has the function of reinforcing the first support member 100, and on the other hand, the first guide wall 271 and the second guide wall 272 of the second reinforcing rib 262 can also make the first support member 100 slide more stably relative to the second support member 200.

[0479] Exemplarily, the second support member 200 is provided with a first avoidance opening 2010 , and the first avoidance opening 2010 is located between the third sliding sub-groove 2031 and the fourth sliding sub-groove 2032 . The advantage of such a configuration is that the structure of the telescopic support leg 2 a is more compact.

[0480] Exemplarily, 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 is connected to at least one third reinforcing rib 263, and when the first support member 100 slides relative to the second support member 200, the first avoidance opening 2010 serves as an opening for avoiding the second reinforcing rib 262 and the third reinforcing rib 263; the angle between the extension direction of the second reinforcing rib and the extension direction of the first avoidance opening 2010 is 75°-105°, and the angle between the extension direction of the third reinforcing rib and the extension direction of the first avoidance opening 2010 is 0-15°. The benefit of providing the second reinforcing rib 262 and the third reinforcing rib 263 is that the structural strength of the first support member 100 is further improved.

[0481] Exemplarily, the extension direction of the second reinforcement rib 262 is perpendicular to the extension direction of the first avoidance opening 2010 , and the extension direction of the third reinforcement rib 263 is parallel to the extension direction of the first avoidance opening 2010 .

[0482] In some implementations of the embodiments of the utility model, the first support member 100 is slidably mounted 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 leg 2a can support the support rod 1; the second support member 200 is provided with a first avoidance opening 2010, and the first support member 100 has at least one second reinforcement rib 262. When the first support member 100 slides relative to the second support member 200, the first avoidance opening 2010 serves as an opening for avoiding the first reinforcement rib 261.

[0483] For example, the included angle between the extension direction of the second reinforcing rib 262 and the extension direction of the first avoidance opening 2010 is 75°-105°. For example, the extension direction of the second reinforcing rib 262 is perpendicular to the direction of the first avoidance opening 2010 .

[0484] For example, the first support member 100 has at least one third reinforcement rib 263 , and when the first support member 100 slides relative to the second support member 200 , the first avoidance opening 2010 serves as an opening for avoiding the third reinforcement rib 263 .

[0485] For example, the included angle between the extension direction of the third reinforcing rib 263 and the extension direction of the first avoidance opening 2010 is 0-15°. For example, the extension direction of the third reinforcing rib 263 is parallel to the extension direction of the first avoidance opening 2010 .

[0486] Illustratively, each second reinforcement rib 262 is connected to at least one third reinforcement rib 263 .

[0487] 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 avoidance opening 2010, the second guide wall 272 is close to or adjacent to the second side wall 2010b of the first avoidance opening 2010, and the first side wall 2010a and the second side wall 2010b are respectively located on opposite sides of the first avoidance opening 2010; when the first support member 100 slides relative to the second support member 200, the first avoidance opening 2010 serves as an opening for avoiding the first guide wall 271 and the second guide wall 272.

[0492] For example, at least three legs are telescopic legs 2a, and the multi-legged bracket also includes a first mounting portion 5 and at least three first connecting rods 7; the first mounting portion 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 avoidance opening 2010 serves as an opening for avoiding the corresponding first connecting rod 7; during the sliding process of the first mounting portion 5 along the support rod 1, the telescopic leg 2a is stored or opened relative to the support rod 1; the three telescopic legs 2a can be stored to form a first columnar structure, and after the three telescopic legs 2a are stored 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 avoidance opening 2010.

[0493] The utility model embodiment also proposes a multi-legged bracket, referring to Figure 27-48The multi-legged 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, the support rod 1 is used to support an 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, the first support member 100 is slidable relative to the second support member 200, the first support member 100 includes a first main body 130 and a first positioning member 170 provided on the first main body 130 The first positioning member 170 is provided with a first damping protrusion 110, and the first damping protrusion 110 is in 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 a supporting state; the second support member 200 is provided with a first sliding groove 201, and 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.

[0494] It can be understood that the first positioning member 170 and the first body 130 constitute a first supporting body.

[0495] For example, refer to Fig.48 The embodiment of the utility model proposes a shooting bracket, including a shooting terminal 3 and a multi-legged bracket, wherein a support rod 1 of the multi-legged bracket is used to support the shooting terminal 3, and the shooting terminal 3 can be a mobile phone, a tablet, etc.

[0496] For example, the first positioning member 170 is integrally provided on the first body 130 , or the first positioning member 170 is detachably provided on the first body 130 .

[0497] For example, the first positioning member 170 is fixed to the first body 130 .

[0498] For example, the first positioning member 170 serves as the first sliding portion 140 that is slidably matched with the first sliding groove 201 , so as to achieve the sliding installation of the first supporting member 100 on the second supporting member 200 .

[0499] It can be understood that the first support member 100 can be positioned on the second support member 200 through the first damping protrusion 110 .

[0500] For example, the first positioning member 170 serves as the first sliding portion 140 that is slidably matched with the first sliding groove 201 , and the first sliding portion 140 is circumferentially fixed to the first sliding groove 201 .

[0501] In some implementations of the present utility model, referring to Fig.36The first positioning member 170 has a first base surface 108, the first damping protrusion 110 is located on the first base surface 108 and protrudes relative to the first base surface 108, and 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.

[0502] By way of example, the first base surface 108 is a portion or the entirety of an outer wall of the first positioning member 170 .

[0503] For example, the first base surface 108 is opposite to the first stretching surface 201 a , for example, the cross section of the first stretching surface 201 a is arc-shaped, and the cross section of the first base surface 108 is arc-shaped.

[0504] In some implementations of the present utility model, referring to Fig.36 Etc., the first damping protrusion 110 extends in a strip shape.

[0505] For example, the first damping protrusion 110 is in the shape of an arc strip as a whole.

[0506] In some implementations of the present utility model, referring to Fig.36 Etc., there is a second connecting line from any point of the first end of the first damping protrusion 110 to any point of 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 connecting line and the first straight line is 75°-90° (e.g., 75°, 80°, 85°, 90°, etc.). The advantage of such a setting is that the damping effect of the first damping protrusion 110 is better.

[0507] In some implementations of the present utility model, referring to Fig.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 side edges 201c extending along the sliding direction of the first support member 100. The distance between the two first side edges 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 side edges 201c. The advantage of such a setting 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.

[0508] For example, the length of the second connecting line is 80%, 85%, 90%, 95%, or 100% of the maximum width of the first sliding slot 201 .

[0509] In some implementations of the present utility model, referring to Fig.36The number of the first damping protrusions 110 is 2, and the 2 first damping protrusions 110 are arranged at intervals along the sliding direction of the first support member 100. The advantage of such an arrangement is that the first support member 100 has at least 2 contact points relative to the second support member 200 along the sliding direction of the first support member 100, so that the first support member 100 is more stable relative to the second support member 200, and the first support member 100 is not easy to shake when it is positioned on the second support member 200, or when the first support member 100 slides relative to the second support member 200.

[0510] In some implementations of the present utility model, referring to Fig.36 The edge of the first damping protrusion 110 is gradually transitioned with the first base surface 108. The advantage of such a configuration is that it is convenient for the first positioning member 170 to be installed in the first sliding groove 201.

[0511] It can be understood 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 relative to the first base surface 108 changes gradually.

[0512] For example, the edge of the first damping protrusion 110 smoothly transitions to the first base surface 108 .

[0513] For example, the edge of the first damping protrusion 110 transitions to the first base surface 108 in an inclined plane.

[0514] In some implementations of the present utility model, referring to Fig.36 When the first positioning member 170 is located between the first main body 130 and the second supporting member 200, the first base surface 108 is fitted with the inner wall of the first sliding groove 201, the first positioning member 170 has a second base surface 109, the second base surface 109 is fitted with the outer wall of the first main body 130, the first positioning member 170 is provided with a first concave cavity 1012, the first concave cavity 1012 is located on the second base surface 109 and is recessed relative to the second base surface 109, and the first concave cavity 1012 corresponds to the first damping protrusion 110. The advantage of such a configuration is that, on the one hand, the first positioning member 170 can be easily inserted into the first sliding groove 201; on the other hand, the first concave 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; on another hand, when the first support member 100 and the second support member 200 are subjected to uneven force (for example, when subjected to force perpendicular to the sliding direction), the first concave cavity 1012 serves as a deformation space for the first damping protrusion 110, thereby avoiding excessive damping force between the first support member 100 and the second support member 200.

[0515] In some implementations of the present utility model, referring to Fig.36The first positioning member 170 is detachably provided on the first main body 130, and is in the form of a thin sheet. The first positioning member 170 is provided with a first opening 1010, and the first positioning member 170 can be installed into the first main body 130 through the first opening 1010. The advantage of such a configuration is that the first positioning member 170 is easy to install.

[0516] For example, when installing the first positioning member 170, the first positioning member 170 can be pried apart through the first opening 1010 so that the first positioning member 170 can be sleeved on the first body 130. When removing the first positioning member 170, the first positioning member 170 can be pried apart through the first opening 1010 so that the first positioning member 170 can be removed from the first body 130.

[0517] For example, the first positioning member 170 is in 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.

[0518] By way of example, the first opening 1010 and the first sliding slot 201 extend in the same direction.

[0519] In some implementations of the present utility model, referring to Fig.36 The first positioning member 170 is detachably provided on the first main 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 main body 130. The first main body 130 is provided with two holding walls 1011. The first positioning member 170 is held between the two holding walls 1011 so that 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 main body 130. The advantage of such a setting is that when the first support member 100 slides relative to the second support member 200, the first positioning member 170 is not easy to be separated from the first main body 130.

[0520] For example, the two holding walls 1011 are respectively located on the two holding protrusions 180 , and the two holding protrusions 180 are respectively protruded from the first body 130 , and the two holding protrusions 180 are arranged at intervals.

[0521] 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 .

[0522] For example, the first limiting wall 102 is located on one of the holding protrusions 180 , and the first limiting wall 102 is opposite to the holding wall 1011 of the holding protrusion 180 .

[0523] In some implementations of the present utility model, referring to Fig.36 The first support member 100 has a first end and a second end. When the telescopic leg 2a is the longest, 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 the telescopic leg 2a has a longer support length.

[0524] In some implementations of the present utility model, referring to Fig.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 of the first support member 100 relative to the second support member 200, the first positioning protrusion 131 can abut against or slide over 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 on the second support member 200 when the telescopic leg 2a is in a supporting state.

[0525] In some implementations of the utility model, referring to 35, 38, 41, etc., the second support member 200 is provided with a second damping protrusion 230, and the second damping protrusion 230 is in 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 a supporting state.

[0526] It can be understood that the first support member 100 is positioned on the second support member 200 via the second damping protrusion 230 .

[0527] In some implementations of the present utility model, referring to Fig.35 , 38 , 41, etc., the second support member 200 includes a second body 210 and a second positioning member 220 disposed on the second body 210, the second damping protrusion 230 is disposed on the second positioning member 220, the first body 130 is slidably sleeved on the second positioning member 220, and the second damping protrusion 230 is in damping contact with the first body 130. The advantage of such a setting is that the first support member 100 is slidably mounted on the second positioning member 220 and the first support member 100 is slidably mounted on the first sliding groove 201, thereby improving the stability of the first support member 100 when sliding.

[0528] 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 .

[0529] In some implementations of the present utility model, referring to Figure 35-39The second positioning member 220 is disposed between the first body 130 and the second body 210, and the second positioning member 220 has a third base surface 2011. The second damping protrusion 230 is located on the third base surface 2011 and bulges relative to the third base surface 2011, and the third base surface 2011 is adapted to the outer wall of the first body 130. The advantage of such a configuration is that the second damping protrusion 230 is easily disposed.

[0530] By way of example, the third base surface 2011 is a part or the entirety of the inner wall of the second positioning member 220 .

[0531] For example, the third base surface 2011 is the third stretching surface 203 a (or the third base surface 2011 is a part of the third stretching surface 203 a ), and the cross section of the third base surface 2011 is arc-shaped.

[0532] In some implementations of the present utility model, referring to Figure 35-39 The third base surface 2011 is in contact with the outer wall of the first main body 130, the second positioning member 220 has a fourth base surface 2012, the fourth base surface 2012 is in contact with the inner wall of the second main body 210, the third base surface 2011 is opposite to the fourth base surface 2012, the second positioning member 220 is provided with a second concave cavity 2013, the second concave cavity 2013 is located on the fourth base surface 2012 and is recessed relative to the fourth base surface 2012, and the second concave cavity 2013 corresponds to the second damping protrusion 230. On the one hand, the second positioning member 220 is easily installed in the first sliding groove 201. On the other hand, the second cavity 2013 and the first 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. On the other hand, when the first support member 100 and the second support member 200 are subjected to uneven force (for example, when subjected to force perpendicular to the sliding direction), the second cavity 2013 serves as a deformation space for the second damping protrusion 230, thereby avoiding excessive damping force between the first support member 100 and the second support member 200.

[0533] It can be understood 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 201 a of the first sliding groove 201 .

[0534] In some implementations of the present utility model, referring to Figure 35-39 The second damping protrusion 230 extends in a strip shape, and there is a third connecting line from any point of the first end of the second damping protrusion 230 to any point of the second end of the second damping protrusion 230, and the first support member 100 extends along the first straight line, and the angle between the third connecting line and the first straight line is 75°-90° (for example, 75°, 80°, 85°, 90°, etc.). The advantage of such a setting is that the damping effect of the first damping protrusion 110 is better.

[0535] In some implementations of the present utility model, referring to Figure 35-39 The number of the second damping protrusions 230 is 2, and the two second damping protrusions 230 are arranged at intervals along the 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 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 body 130, the distance between the two first side edges 203c is the maximum width of the second sliding groove 203, and the two second damping protrusions 230 are respectively located at or close to the first side edges 203c. 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.

[0536] In some implementations of the present utility model, referring to Figure 35-39 The edge of the first damping protrusion 110 is gradually transitioned to the third base surface 2011. The advantage of such a configuration is that it is convenient for the first support member 100 to be installed into the first positioning member 170.

[0537] It can be understood 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 relative to the third base surface 2011 changes gradually.

[0538] For example, the edge of the second damping protrusion 230 smoothly transitions to the third base surface 2011 .

[0539] For example, the edge of the second damping protrusion 230 transitions to the third base surface 2011 in an inclined plane.

[0540] In some implementations of the present utility model, referring to Figure 35-39 The second positioning member 220 is in the shape of a thin sheet and is detachably disposed on the second body 210 .

[0541] In some implementations of the present utility model, referring to Figure 35-39 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 protrusion 230 is close to or located at the first end of the second support member 200.

[0542] In some implementations of the present utility model, referring to Figure 35-39The first support member 100 has a first damping protrusion 110, which is in 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 support leg 2a is in a supporting state; the first support member 100 has a first base surface 108, the first damping protrusion 110 is located on the first base surface 108 and bulges relative to the first base surface 108, and 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 is convenient to provide the first damping protrusion 110.

[0543] For example, the first base surface 108 is located on the first positioning member 170 of the first support member 100 , or the first base surface 108 is located on the first body 130 of the first support member 100 .

[0544] In some implementations of the present utility model, referring to Figure 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 is in 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 .

[0545] In some implementations of the present utility model, referring to Figure 35-39 The first support member 100 has a second base surface 109, a first thin wall is formed between the first base surface 108 and the second base surface 109, and the first support member 100 is provided with a first concave cavity 1012, which is located on the second base surface 109 and is recessed relative to the second base surface 109, and the first concave cavity 1012 corresponds to the first damping protrusion 110. The advantage of such a setting is that the first concave 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. On the other hand, when the first support member 100 and the second support member 200 are subjected to uneven force (for example, when subjected to force perpendicular to the sliding direction), the first concave cavity 1012 serves as a deformation space for the first damping protrusion 110, thereby avoiding excessive damping force between the first support member 100 and the second support member 200.

[0546] For example, the first thin wall is a part of the first positioning member 170 , or is a thin-walled structure provided on the first body 130 in any manner.

[0547] By way of example, the first base surface 108 and the second base surface 109 are both located on the first body 130 .

[0548] By way of example, the first base surface 108 and the second base surface 109 are both located on the first positioning member 170 .

[0549] In some implementations of the present utility model, referring to Figure 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 is in 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 support leg 2a is in a supporting state.

[0550] It can be understood that the first support member 100 can be positioned on the second support member 200 through the second damping protrusion 230 .

[0551] For example, the first supporting member 100 is slidably mounted on the second positioning member 220 .

[0552] For example, the second positioning member 220 is disposed between the first supporting member 100 and the second body 210 , and the third base surface 2011 is adapted to the outer wall of the first supporting member 100 .

[0553] For example, the third base surface 2011 is in contact with the outer wall of the first support member 100 .

[0554] For example, the first support member 100 is slidably installed in the second sliding groove 203, and 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 the two second damping protrusions 230 are respectively located at or close to the first side edges 203c.

[0555] For example, the second positioning member 220 is in the shape of a thin sheet, and the second positioning member 220 is detachably provided on the second body 210;

[0556] 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.

[0557] In some implementations of the present utility model, referring to Figure 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 portion 2019, and the second positioning member 220 is provided with a first limiting portion 223.

There is a second thin wall between the third base surface 2011 and the fourth base surface 2012. The second support member 200 has two third concave cavities 2014. The third concave cavities 2014 are located on the fourth base surface 2012 and are recessed relative to the fourth base surface 2012. The two third concave cavities 2014 are respectively close to or located at the two ends of the second thin wall. In the process of the second positioning member 220 sliding over the second extrusion protrusion 192, the third concave cavity 2014 serves as a deformation space for the second thin wall; the positioning cavity 2015 is located between the two third concave cavities 2014.

[0614] Specifically, the multi-legged bracket further 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 supporting members 100, and the other end is rotatably connected to the support rod 1, and 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, so that the telescopic leg 2a can be stored in the support rod 1, or the telescopic leg 2a can be opened relative to the support rod 1.

[0615] A multi-legged stand according to an embodiment of the utility model is characterized in that the multi-legged stand comprises a support rod and at least three legs, wherein the at least three legs are used to support the support rod, and the support rod is used to support an electrical main body, and characterized in that at least one of the at least three legs is a telescopic leg, and the telescopic leg comprises two first support members and a second support member, wherein the two first support members are both slidably mounted on the second support member, and the two first support members can be slidably extended relative to the two ends of the second support member to change the length of the telescopic leg; the first support member can be positioned on the second support member so that the telescopic leg can support the support rod. The advantage of such a setting is that the telescopic range of the telescopic leg is larger.

[0616] In the implementation of the embodiment of the utility model, the telescopic legs can be implemented in the following ways:

[0617] 1. The telescopic support leg comprises a first support member and a second support member, wherein the first support member is sleeved on the second support member;

[0618] 2. The telescopic support leg comprises two first support members and a second support member, and the two first support members are both slidably mounted on the second support member.

[0619] Reference Figures 67-68 The embodiment of the utility model further 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 mounted on the second support member 200 to change the length of the telescopic support leg.

[0620] For example, the second support member 200 has a first sliding groove 201, and the first support member 100 is slidably mounted in the first sliding groove 201.

[0621] 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 matched, for example, the first support member 100 and the first sliding groove 201 of the second support member 200 are clearance matched.

[0622] When the telescopic leg 2a supports the support rod 1, the first support member 100 is subjected to pressure along its sliding direction, and 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 (tangential constraint force) between the first support member and the second support member.

[0623] The second support member 200 has a second contact surface 2016 in contact with the first support member 100. When the telescopic support leg 2a is in a supporting 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 supporting 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.

[0624] By way of example, the second contact surfaces 2016 are two opposite side surfaces of the first sliding groove 201 .

[0625] Reference Figures 98 to 106 (or Figures 107 to 119 ), the embodiment of the utility model also proposes a telescopic support leg 2a, the telescopic support leg 2a includes a first support member and a second support member, the second support member is provided with a first sliding groove, the first support member is sleeved in the first sliding groove, the first support member can slide relative to the first sliding groove to change the length of the telescopic support leg; the first support member is in damping contact with the first sliding groove so that the first support member can be positioned at the second support member when the telescopic support leg is in a supporting 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 is in damping contact with the first sliding groove so that the first support member forms a damping contact with the first sliding groove.

[0626] It can be understood that the telescopic legs of the embodiment of the utility model can be applied to the multi-legged bracket of the embodiment of the utility model.

[0627] By way of example, the first sliding groove is a columnar groove, and the first support member is circumferentially fixed relative to the first sliding groove.

[0628] By way of example, the first sliding groove has two first side edges extending along the sliding direction of the first support member, the distance between the two first side edges is the maximum width of the first sliding groove, the number of the first damping protrusions is two, and the two first damping protrusions dampen sliding on the inner wall of the first sliding groove to form two first damping contact tracks, and the two first damping contact tracks are close to or located at the two first side edges.

[0629] For other examples, see Fig.101 The number of the first damping protrusion is 1, and the first damping protrusion is close to one of the first side edges.

[0630] For other examples, see Fig.114 The number of the first damping protrusion is 1, and the first damping protrusion is located at or close to the middle position between the two first side edges.

[0631] In some implementations of the present utility model, referring to Fig.101 The first supporting body includes a first body and a first sliding portion protruding from the first body, the first sliding portion is adapted to the first sliding groove, the first body and the first sliding groove have a first gap, the first sliding portion is slidably installed in the first sliding groove so that the first supporting member can slide relative to the first sliding groove; the first damping protrusion is protruding from the first sliding portion, the first damping protrusion is in damping contact with the inner wall of the first sliding groove, and the first body is sleeved in the first sliding groove.

[0632] In some implementations of the embodiment of the utility model, the first damping protrusion can be detachably provided on the first supporting body, the first supporting body is provided with a mounting groove adapted to the first damping protrusion, and the first damping protrusion is located in the mounting groove.

[0633] In some implementations of the present utility model, referring to Fig.101 The first damping protrusion is detachably provided on the first sliding part, and the first sliding part is provided with a mounting groove 1013, and the mounting groove 1013 is adapted to the first damping protrusion. The first damping protrusion is detachably provided on the mounting groove 1013. The first damping protrusion is provided on the mounting groove 1013 to prevent the first damping protrusion from falling off relative to the first sliding part during the sliding process of the first support member relative to the second support member. The first damping protrusion is detachably provided on the first sliding part, so that the first damping protrusion can be made of a suitable damping material, so that the telescopic support leg can achieve a better positioning effect within a reasonable cost. For example, the first damping protrusion can be made of silicone.

[0634] In some implementations of the present utility model, referring to Fig.101 or Fig.104The first damping protrusion has a damping contact surface 1014, and a deformation cavity 1015 is formed in the first damping protrusion. The deformation cavity 1015 is connected to the damping contact surface 1014, and the damping contact surface 1014 surrounds the deformation cavity 1015. The advantage of providing the deformation cavity 1015 is 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 be easily deformed by using the deformation cavity 1015 to facilitate the first support member to be installed 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 be easily deformed by using the deformation cavity 1015 to avoid excessive damping force between the first support member and the second support member.

[0635] For example, the damping contact surface is in a circular ring shape, and the deformation cavity 1015 is a cylindrical cavity.

[0636] In other examples, the first damping protrusion is not provided with a deformation cavity 1015.

[0637] In other examples, the deformation cavity 1015 is disposed below the damping contact surface 1014 (ie, the deformation cavity 1015 does not penetrate the damping contact surface 1014 ).

[0638] For example, refer to Fig.101 or Fig.104 The first damping protrusion is in the shape of a sheet, for example, the first damping protrusion is in the shape of a disc.

[0639] For example, refer to Fig.101 or Fig.104 Before the first support member is installed into the second support member, the damping contact surface 1014 can be a plane. After the first support member is installed into the second support member, the damping contact surface 1014 contacts the inner wall of the first sliding groove 101 (for example, the first stretching surface 201a). The damping contact surface 1014 can produce adaptive deformation according to the shape of the inner wall of the first sliding groove 101. For example, the cross-section of the first stretching surface 201a is an arc, and the damping contact surface 1014 is deformed into an arc surface after contacting the first stretching surface 201a.

[0640] In other examples, before the first support member is installed into the second support member, the damping contact surface 1014 is a surface adapted to the inner wall of the first sliding groove 101, and after the first support member is installed into the second support member, 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-shaped surface adapted to the first stretching surface 201a.

[0642] In other examples, the first sliding groove has two first side edges extending along the sliding direction of the first support member, the distance between the two first side edges is the maximum width of the first sliding groove, the number of the first damping protrusions is 2, and the two first damping protrusions dampen sliding on the inner wall of the first sliding groove to form two first damping contact tracks, and the two first damping contact tracks are close to or located at the two first side edges.

The first damping protrusion is detachably provided on the first positioning member, so that the first damping protrusion can be conveniently selected from a suitable damping material, so that the telescopic support leg can achieve a better positioning effect within a reasonable cost.

[0651] For example, the first mounting sub-groove 1013a is a blind groove, and the first damping protrusion is located between the first positioning member and the second supporting member.

[0652] For example, refer to Fig.114 The first mounting sub-groove 1013a passes through the first positioning member, and the first damping protrusion is located between the first body and the second supporting member.

The advantage of setting the second mounting sub-groove 1013b is that it makes the first damping protrusion less likely to separate from the first positioning piece.

[0654] Understandably, referring to Fig.114 The first positioning member and the first main body constitute the first supporting body, the first positioning member serves as the first sliding portion 140 that slides with the first sliding groove 201, and the first sliding portion 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.
