In the present embodiment, a gasket 602 is sleeved on the bolt connecting piece 603, and the two ends of the bolt spring 605 are respectively abutted between the gasket 602 and the bolt 6.

[0089] The head of the bolt 6 is in the shape of a circular truncated cone, and the positioning hole 302 is a circular hole, that is, the head of the bolt 6 has a tapered surface, so that the cross-sectional diameter of each part of the head of the bolt 6 is different in the axial direction, and when the head of the bolt 6 is inserted into the circular positioning hole 302, the head of the bolt 6 can be clamped in the positioning hole 302 after being clamped in a part of the positioning hole 302, and further clamped to achieve locking under the compression of the bolt spring 605, so that the structure of the head of the bolt 6 can make the cooperation between the bolt 6 and the positioning hole 302 more compact, and the fixing effect is better and more stable.

[0090] The movable supporting arm 2 is provided with a locking button 4, and pushing the locking button 4 away from the sliding groove 301 can compress the bolt spring 605 and drive the head of the bolt 6 to exit the positioning hole 302, and when the locking button 4 is reset, the head of the bolt 6 can be inserted into one of the positioning holes 302 under the action of the bolt spring 605 to achieve locking positioning.

[0091] Specifically, as shown in FIGS. 3, 4 and 5, the movable supporting arm 2 is provided with a strip-shaped hole 501 arranged horizontally with the sliding cavity, one end of the locking button 4 is connected with a locking connecting rod 401, the locking connecting rod 401 passes through the strip-shaped hole 501 and can slide horizontally in the strip-shaped hole 501, and the locking connecting rod 401 is connected with the bolt connecting piece 603, and in the embodiment, a screw hole 604 is formed in the bolt connecting piece 603, the locking connecting rod 401 is in the structure of a screw rod, and the locking connecting rod 401 is threadedly connected with the screw hole 604 in the bolt connecting piece 603 after passing through the strip-shaped hole 501, so as to realize the connection and cooperation between the locking button 4 and the bolt connecting piece 603, and thus pushing the locking button 4 away from the positioning hole 302 can drive the bolt connecting piece 603 to drive the head of the bolt 6 to exit the positioning hole 302.

[0094] The specific implementation process is as follows:

[0095] In actual use, the mounting block 3 can be mounted on a specific device according to actual needs, for example, the mounting block 3 is mounted on a handle for use, so that the handle and the camera are mounted and connected. When the up-down position of the handle needs to be adjusted, the locking button 4 is actuated in a direction away from the sliding groove 301, so that the locking connecting rod 401 drives the latch connecting piece 603 to slide away from the sliding groove 301, the latch spring 605 is compressed, the latch connecting piece 603 drives the latch 6 to slide away from the sliding groove 301 and exit the positioning hole 302, at this time, the movable supporting arm 2 and the mounting block 3 are disconnected with each other, and the vertical position between the two can be adjusted by sliding the mounting block 3 or the movable supporting arm 2 up and down, so as to adjust the up-down position of the handle.

[0096] When the position is adjusted to a suitable position and the latch 6 is aligned with the positioning hole 302, the locking button 4 is released, at this time, the latch spring 605 generates a reset movement, the locking button 4 moves to the direction close to the sliding groove 301 under the action of the latch spring 605, the head of the latch 6 gradually inserts into the corresponding positioning hole 302, and the head of the latch 6 has a taper surface, which can tightly lock the latch 6 in the positioning hole 302 under the pressure of the latch spring 605, so as to limit and fix the movable supporting arm 2 and the handle support.

[0097] In this embodiment, the connection, limiting and up-down sliding adjustment between the movable supporting arm 2 and the mounting block 3 can be achieved by actuating the locking button 4 without the aid of other tools, which is simple and convenient to operate.

[0098] Referring to FIGS. 11, 12 and 13, in this embodiment, the guide channel is a sliding groove 301 arranged on the mounting block 3, and a plurality of locking notches 120 are arranged on the side wall of the sliding groove 301 and are sequentially and spacedly distributed along the length direction of the mounting block 3.

[0099] The sliding table 130 is slidably arranged in the sliding groove 301, and the sliding table 130 has a mounting cavity 131, one side of the sliding table 130 opposite to the bottom of the sliding groove 301 is configured with a first opening 133 communicating with the mounting cavity 131, and one end of the movable supporting arm 2 is movably connected to the side of the sliding table 130 configured with the first opening 133; the side of the sliding table 130 facing the locking notches 120 is configured with a strip-shaped opening 134, the strip-shaped opening 134 communicates with the mounting cavity and is arranged to extend along the depth direction of the sliding groove 301.

[0100] The locking assembly 140 includes a locking piece 141 and a lever 142. The locking piece 141 is slidingly arranged in the mounting cavity 131 and extends out through the strip-shaped opening 134. One end of the lever 142 extends into the mounting cavity 131 through the first opening 133 and is connected with the locking piece 141. The lever 142 can drive the locking piece 141 to move in the strip-shaped opening 134. The part of the locking piece 141 extending out of the strip-shaped opening 134 can enter the locking gap 120 to lock the sliding table 130 relative to the mounting block 3. The part of the locking piece 141 extending out of the strip-shaped opening 134 can be out of the locking gap 120 to release the locking of the sliding table 130 relative to the mounting block 3.

[0101] Unlike the foregoing embodiments, the locking gap 120 is arranged on the side wall of the sliding groove 301 instead of the bottom, so that the transmission direction of the locking force is more reasonable and the lateral load generated by the movable support arm 2 during use can be effectively borne.

[0102] Specifically, the guide channel is a sliding groove 301 arranged on the mounting block 3. The sliding groove 301 can have a T-shaped groove, a dovetail groove or a rectangular groove, and can be processed by milling, extrusion or die casting. The side wall of the sliding groove 301 is provided with a plurality of locking gaps 120 which are sequentially and spacedly distributed along the length direction of the mounting block 3. The locking gap 120 can be formed by one-piece molding during casting or extrusion, or can be formed by post-machining such as milling, stamping or laser cutting. The shape of the locking gap 120 can be rectangular, trapezoidal, arc-shaped or wedge-shaped, and the size thereof needs to match the extending part of the locking piece 141. The spacing distance can be 5mm, 8mm, 10mm or 12mm, etc.

[0103] The sliding table 130, as the bearing base of the movable component, is slidingly arranged in the sliding groove 301. The material of the sliding table 130 can be aluminum alloy, stainless steel or high-strength plastic, etc. The sliding table 130 can be gap-fitted or transition-fitted with the sliding groove 301, and a wear-resistant sleeve or bearing can be added to reduce friction if necessary. The sliding table 130 has a mounting cavity 131 which provides a mounting space for the locking assembly 140. The shape and size of the cavity need to be designed according to the structure of the locking piece 141. The side of the sliding table 130 opposite to the bottom of the sliding groove 301 is provided with a first opening 133 which communicates with the mounting cavity 131. One end of the movable support arm 2 is movably connected with the side of the sliding table 130 provided with the first opening 133. The connection mode can be screw connection, buckle connection or welding, etc.

[0104] The sliding base 130 is configured with a strip-shaped opening 134 on the side facing the locking gap 120, which is in communication with the mounting cavity 131 and extends along the depth direction of the sliding groove 301. The opening provides a channel for the extension and retraction of the locking piece 141, and the width and length thereof need to ensure that the locking piece 141 can smoothly enter and exit the locking gap 120.

[0105] The locking assembly 140 includes a locking piece 141 and a lever 142. In this embodiment, the locking piece 141 is mainly used to lock the sliding base 130 relative to the sliding groove 301, and can be in the shape of a wedge, a cylinder or a special-shaped block, and can be made of tool steel, stainless steel or hard alloy or other high-strength materials. The lever 142 is used for user operation to realize locking or unlocking. The lever 142 can be designed in the shape of a straight rod, an L shape or a T shape, and the surface thereof can be provided with anti-slip textures or coated with soft materials to improve the operation comfort. The locking piece 141 is slidingly arranged in the mounting cavity 131, and only part of the lever 142 can extend into the mounting cavity 131 to be connected with the locking piece 141. The connection mode can be screw connection, pin shaft connection or integral molding.

[0106] Further, the locking piece 141 has at least part thereof extending out of the mounting cavity 131 through the strip-shaped opening 134 and can extend into the locking gap 120 to realize reliable locking of the sliding base 130 relative to the mounting block 3.

[0107] In actual operation, when the photographer needs to adjust the handle position to adapt to different shooting angles or holding requirements, first hold the lever 142 with the hand and pull the lever 142 away from the sliding groove 301. At this time, the lever 142 drives the locking piece 141 to move synchronously through the connecting mechanism, so that the locking piece 141 completely comes out of the current locking gap 120, and the locking state of the sliding base 130 relative to the mounting block 3 is released. After the locking state is released, the user can push the sliding base 130 or directly push the movable support arm 2 with the other hand, so that the sliding base 130 moves stably along the sliding groove 301, and the movement of the sliding base 130 drives the movable support arm 2 to realize position adjustment. For example, when low-angle shooting is performed, the support arm can be moved downward by 20-30 mm; when a higher operating position is needed, the support arm can be moved upward by a corresponding distance. During the movement, the user can select a suitable locking gap 120 position according to actual needs. When the sliding base 130 moves to the target position, the user pushes the lever 142 to move toward the sliding groove 301, drives the locking piece 141 to re-enter the corresponding new locking gap 120, and completes the relocking of the position. The whole adjustment process is intuitive, and the user can directly observe the cooperation state of the locking piece 141 and the locking gap 120 to ensure the reliability of the locking.

[0108] The beneficial effects of the technical scheme of the present application are as follows: by arranging a plurality of locking gaps 120 distributed along the length direction on the side wall of the sliding groove 301, and cooperating with the strip-shaped opening 134 and the locking assembly 140 on the sliding table 130, the step-by-step precise positioning adjustment of the movable support arm 2 is realized. The locking mode of the locking piece 141 extending through the strip-shaped opening 134 and entering the locking gap 120 makes the transmission of the locking force more direct and effective, can bear greater lateral load, and improves the reliability and stability of the connection. The operation mode of the lever 142 is intuitive and simple, and the user only needs to perform simple pulling and pushing actions to complete the whole process of unlocking, adjustment and relocking, without using any special tools, greatly improving the operation efficiency. The sliding cooperation of the sliding table 130 in the sliding groove 301 ensures the stability and accuracy of the movement of the movable support arm 2, avoiding the jamming or deflection problems that may occur in the traditional threaded adjustment mode. The lateral arrangement of the locking gap 120 enables the locking piece 141 to effectively resist various external forces generated during the use of the movable support arm 2, especially the vibration and impact load generated during handheld shooting, ensuring the stability of the position of the photographic equipment. The overall structure is compact and reasonable, and the components are precisely matched, which not only meets the use demand of rapid adjustment, but also ensures the reliability and durability during long-term use, and is especially suitable for professional photography and video shooting and other application scenarios with high requirements for equipment stability.

[0109] Referring to FIGS. 14-17, in the present embodiment, the locking assembly 140 further includes a locking bushing 143 arranged in the mounting cavity 131, the locking piece 141 and the lever 142 extending into the mounting cavity 131 are sleeved, and the locking bushing 143 is threadedly connected with one end of the lever 142 extending into the mounting cavity 131 and abuts against the locking piece 141.

[0110] In the present embodiment, the locking assembly 140 further includes a locking bushing 143 arranged in the mounting cavity 131, which serves as an intermediate force transmission element connecting the lever 142 and the locking piece 141, and plays a key role in structural support and force transmission. Specifically, the locking piece 141 and the lever 142 extending into the mounting cavity 131 are connected in a sleeved manner. This sleeved structure can be that the locking piece 141 is sleeved outside the lever 142, or the lever 142 is sleeved inside the locking piece 141. The sleeved fit can be gap fit or transition fit, to ensure that the two can move synchronously without relative sliding.

[0111] The locking bush 143 is threadedly connected with the end of the push rod 142 extending into the mounting cavity 131. The thread connection can be in the form of internal thread cooperating with external thread, and the thread specification can be selected from M3, M4, M5 standard thread or special pitch trapezoidal thread, etc. The thread connection not only ensures the reliability of the connection, but also facilitates disassembly and maintenance when needed. At the same time, the locking bush 143 and the locking piece 141 form an abutting relationship, and when the push rod 142 rotates, the locking bush 143 is driven to move through the thread connection, and the locking bush 143 pushes the locking piece 141 to realize the extension and retraction movement.

[0112] The locking bush 143 is threadedly connected with the end of the push rod 142 extending into the mounting cavity 131. The thread connection can be in the form of internal thread cooperating with external thread, and the thread specification can be selected from M3, M4, M5 standard thread or special pitch trapezoidal thread, etc. The thread connection not only ensures the reliability of the connection, but also facilitates disassembly and maintenance when needed. At the same time, the locking bush 143 and the locking piece 141 form an abutting relationship, and when the push rod 142 rotates, the locking bush 143 is driven to move through the thread connection, and the locking bush 143 pushes the locking piece 141 to realize the extension and retraction movement.

[0113] Continuing to refer to FIG. 17, in the present embodiment, a first limiting protrusion 132 is configured in the mounting cavity 131, and the first limiting protrusion 132 is located in the middle of the mounting cavity. The locking assembly 140 further includes a third elastic member 145 sleeved with the locking bush 143. An end of the third elastic member 145 abuts against the first limiting protrusion 132, and the other end abuts against a second limiting protrusion 144 configured at the end of the locking bush 143 away from the first opening 133.

[0114] In the present embodiment, in order to realize the automatic reset function of the locking assembly 140, a first limiting protrusion 132 is configured in the mounting cavity 131, and the first limiting protrusion 132 is located in the middle of the mounting cavity 131 as a support basis for the elastic member. The first limiting protrusion 132 can be directly formed when the mounting cavity 131 is machined in an integral molding manner, or can be separately machined and assembled. The shape can be a ring-shaped boss, a square-shaped block or other suitable geometric shape.

[0115] The locking assembly 140 further includes a third elastic member 145 sleeved with the locking bush 143. The third elastic member 145 can be a compression spring, a disc spring or an elastic rubber ring, etc. The elastic coefficient and pre-compression amount thereof need to be designed according to the weight of the locking piece 141 and the required reset force. The end of the locking bush 143 away from the first opening 133 is configured with a second limiting protrusion 144. The second limiting protrusion 144 and the locking bush 143 can be integrally machined, or can be fixed by thread connection, press fitting or other mechanical connection methods. The shape can also be ring-shaped, square-shaped or other suitable structure.

[0116] The mounting mode of the third elastic member 145 is that one end is in abutment with the first limiting protrusion 132, and the other end is in abutment with the second limiting protrusion 144. Through the arrangement of the first limiting protrusion 132 and the second limiting protrusion 144, a compression support basis is provided for the third elastic member 145, so that the third elastic member 145 can stably work in the mounting cavity 131. When the user operates the pull rod 142 to move the locking bushing 143, the third elastic member 145 is compressed to store elastic potential energy; after the user releases the operation, the elastic restoring force of the third elastic member 145 pushes the locking bushing 143 and the locking member 141 to automatically reset to the initial locking position, realizing the automatic reset function. In this way, it is ensured that the locking assembly 140 can reliably return to the locked state after each operation, avoiding the problem of locking failure caused by improper or forgotten operation of the user, and improving the safety and reliability of use.

[0117] Referring to FIGS. 14 and 18, in the embodiment, the mounting cavity 131 includes a first cavity 138a and a second cavity 138b, one end of the first cavity 138a is in communication with the first opening 133, one end of the second cavity 138b is in communication with the other end of the first cavity 138a, the inner diameter of the first cavity 138a is smaller than the inner diameter of the second cavity 138b, and the locking member 141 is located in the first cavity 138a; the locking assembly 140 further includes a third elastic member 145 sleeved with the locking bushing 143, the end of the locking bushing 143 away from the first opening 133 is configured with a second limiting protrusion 144, the third elastic member 145 is located in the second cavity 138b, one end of the third elastic member 145 is in abutment with the other end of the first cavity 138a, and the other end of the third elastic member 145 is in abutment with the second limiting protrusion 144.

[0118] In the embodiment, the mounting cavity 131 is formed in two stages, specifically, into a first cavity 138a and a second cavity 138b with different diameters, and the stepped cavity design can better adapt to the installation requirements of different functional components.

[0119] Specifically, one end of the first cavity 138a is in communication with the first opening 133 to provide installation and sliding space for the locking member 141, and one end of the second cavity 138b is in communication with the other end of the first cavity 138a to form a whole cavity structure in communication. The inner diameter of the first cavity 138a is smaller than the inner diameter of the second cavity 138b, and the diameter difference design makes the connection between the first cavity 138a and the second cavity 138b naturally form a step structure, which can serve as a support surface for the elastic member.

[0120] The locking member 141 is located in the first cavity 138a, and due to the smaller diameter of the first cavity 138a, accurate guidance and positioning can be provided for the locking member 141, so that the locking member 141 will not produce radial deviation or swing during axial movement.

[0121] The locking assembly 140 further comprises a third elastic member 145 sleeved with the locking sleeve 143, and the locking sleeve 143 is configured with a second limiting protrusion 144 away from one end of the first opening 133. The third elastic member 145 is located in the second cavity 138b, and makes full use of the large inner diameter space of the second cavity 138b to provide sufficient radial space and a suitable installation environment for the elastic member.

[0122] The third elastic member 145 is installed in a manner that one end abuts against the other end of the first cavity 138a (i.e. the stepped surface at the connection of the two cavities), and the other end abuts against the second limiting protrusion 144. Through this two-section cavity structure, the precise guidance of the locking member 141 is realized, and a suitable working space is provided for the third elastic member 145, so that the structure of the entire locking assembly 140 is more compact and reasonable, the functional division is more clear, and the machining process and assembly process are simplified.

[0123] Referring to FIG. 14, in the present embodiment, the one side of the mounting block 3 provided with the sliding groove 301 is further configured with a sunken table 150, which is in communication with the side wall of the sliding groove 301 provided with the locking gap 120. To ensure that the locking member 141 can completely escape from the locking gap 120 to achieve reliable unlocking, the one side of the mounting block 3 provided with the sliding groove 301 is further configured with a sunken table 150, which is in communication with the side wall of the sliding groove 301 provided with the locking gap 120, forming a retreat space.

[0124] Specifically, the sunken table 150 can be formed by milling, stamping or casting, and its shape can be a rectangular groove, a circular pit or a special-shaped groove matching the shape of the locking member 141. The depth of the sunken table 150 needs to be greater than the thickness of the locking member 141, for example, the depth of the sunken table 150 should be 1-3mm greater than the thickness of the locking member 141 to ensure sufficient allowance. For example, when the thickness of the locking member 141 is 5mm, the depth of the sunken table 150 should be set to 6-8mm; when the thickness of the locking member 141 is 8mm, the depth of the sunken table 150 should be set to 9-11mm, etc.

[0125] In this way, the locking member 141 completely escapes from the locking gap 120 in the unlocked state, eliminating the possible half-locked state, ensuring that the sliding table 130 can freely slide in the sliding groove 301 to achieve complete unlocking.

[0126] Referring to FIG. 14, in the present embodiment, the locking member 141 is arranged in a ring shape, and the outer peripheral wall of the locking member 141 is provided with a flange 141a matching the locking gap 120, and the flange 141a has a taper.

[0127] In the embodiment, the locking member 141 is provided in a ring structure, which has better structural strength and uniform stress distribution, and is convenient for cooperation and installation with other circular or cylindrical components. The ring-shaped locking member 141 can be manufactured by turning, stamping, precision casting or other processes, and the material can be selected from stainless steel, aluminum alloy or high-strength engineering plastic, etc.

[0128] The outer peripheral wall of the locking member 141 is provided with a flange 141a matched with the locking gap 120, which serves as an actual locking part and has a size and shape matched with the locking gap 120 on the side wall of the sliding groove 301. The flange 141a can be a continuous annular flange 141a, or a plurality of flange 141a segments distributed on the circumference, which is determined according to the requirement of locking force and the requirement of processing technology.

[0129] In particular, the flange 141a has a taper design, for example, the taper angle is set to 3°-15°, and the commonly used taper angles are 5°, 8° or 10°, etc. The taper setting makes the flange 141a have self-centering and guiding effect when entering the locking gap 120, which can automatically adjust the position to achieve the best cooperation state. At the same time, the taper structure produces a wedging effect when locking, which enhances the reliability and stability of the locking. When unlocking, the taper structure is also conducive to the flange 141a smoothly coming out of the locking gap 120, reducing the operation resistance.

[0130] Referring to FIG. 17, in the embodiment, a plurality of positioning holes 302 are sequentially and spaced apart in the length direction of the sliding groove 301; at least one wave bead mounting hole 222 is provided on the side of the sliding table 130 facing the plurality of positioning holes 302, the wave bead mounting hole 222 is provided with a positioning wave bead 7 and a wave bead spring 701, both ends of the wave bead spring 701 are connected with the positioning wave bead 7 and the wave bead mounting hole 222 respectively, and the wave bead spring 701 pushes the positioning wave bead 7 to be clamped into the positioning hole 302.

[0131] In the embodiment, on the basis of the foregoing side edge locking gap 120 locking mechanism, an auxiliary positioning mechanism is further provided, forming a double positioning system, which realizes more accurate and reliable position adjustment and locking.

[0132] Specifically, a plurality of positioning holes 302 are sequentially and spaced apart in the length direction of the sliding groove 301, which are provided on the bottom of the sliding groove 301 and form a cooperation relationship with the locking gap 120 on the side wall. The positioning hole 302 can be processed by drilling, milling or stamping, etc., for example, the hole diameter is 2-4mm, the depth is 2-5mm, and the spacing between the holes can be consistent with the spacing of the locking gap 120, to ensure that the two sets of positioning systems can work synchronously. The shape of the positioning hole 302 can be circular, oval or conical, etc., to adapt to different types of positioning wave beads 7.

[0133] The side of the sliding table 130 facing the plurality of positioning holes 302 is provided with at least one wave bead mounting hole 222, the number of which can be set according to the length of the sliding table 130 and the bearing requirement, such as 1, 2 or 3, etc. The wave bead mounting hole 222 can be processed by drilling or boring, and its diameter needs to match the diameter of the positioning wave bead 7, such as the matching tolerance of H7 / g6 or H6 / g5.

[0134] The wave bead mounting hole 222 is provided with a positioning wave bead 7 and a wave bead spring 701. The positioning wave bead 7 can be made of high-hardness materials such as steel ball, ceramic ball or cemented carbide ball, and its diameter can be 3-6mm, with high surface finish requirement to reduce wear. The wave bead spring 701 can be a compression spring or a disc spring, and its elastic coefficient needs to ensure sufficient elastic force to reliably enable the positioning wave bead 7 to be clamped into the positioning hole 302, and also to ensure that it can be smoothly released when the sliding table 130 moves. The two ends of the wave bead spring 701 are respectively connected with the positioning wave bead 7 and the wave bead mounting hole 222, and the connection mode can be direct abutment or indirect connection through a gasket. In this way, the wave bead spring 701 pushes the positioning wave bead 7 to be clamped into the positioning hole 302, forming accurate point-to-point positioning.

[0135] In actual use, the positioning wave bead 7 and the side locking gap 120 form a cooperative double positioning mechanism, improving the accuracy of position adjustment and the operation experience. When the user starts to adjust the position, the first operation of the push rod 142 makes the locking piece 141 released from the side locking gap 120, releasing the main locking state. At this time, the sliding table 130 starts to move in the sliding groove 301, and the positioning wave bead 7 always maintains contact with the bottom of the sliding groove 301 under the pushing of the wave bead spring 701. When the sliding table 130 moves close to the position of a certain positioning hole 302, the positioning wave bead 7 will automatically be clamped into the positioning hole 302, producing a clear "click" sound and tactile feedback, providing clear position indication for the user.

[0136] In this way, the positioning wave bead 7 provides pre-positioning function, and when the sliding table 130 moves to the position of any positioning hole 302, the clamping action of the wave bead automatically stops the sliding table 130 at the accurate position, and the user does not need to search for the accurate locking point. At this time, the corresponding locking gap 120 is also aligned with the locking piece 141, and the user only needs to release the push rod, and the third elastic piece 145 will push the push rod 142, so that the locking piece 141 can accurately enter the locking gap 120 to complete the main locking. Even in poor light or limited operation space, the user can accurately find the positioning point through the tactile and auditory feedback of the wave bead clamping.

[0137] The beneficial effects of the technical scheme of the present application are as follows: by arranging a plurality of positioning holes 302 in the sliding groove 301 and cooperating with the positioning wave bead 7 and wave bead spring 701 mechanism on the sliding table 130, combined with the main locking system of the side locking gap 120, a double positioning and locking mechanism is formed. The positioning wave bead 7 system provides accurate pre-positioning and position feedback function, so that the user can accurately perceive each positioning point during adjustment, avoiding blind adjustment and position deviation problems; the side locking gap 120 system provides strong main locking function, ensuring the stability and reliability of the position after adjustment. The two systems cooperate with each other to ensure the accuracy of adjustment and the reliability of locking. The automatic reset property of the wave bead spring 701 and the manual operation of the locking piece 141 are combined to realize the operation mode of "automatic pre-positioning and manual confirmation locking", which simplifies the operation steps of the user and improves the adjustment efficiency.

[0138] As shown in FIGS. 3 and 4, at least one wave bead mounting hole 222 is arranged at the end of the movable supporting arm 2, and in this embodiment, four wave bead mounting holes 222 are arranged, which are sequentially arranged along the vertical direction of the movable supporting arm 2 and vertically opposite to the sliding cavity.

When the wave bead spring 701 is installed in the movable supporting arm, it is in a compressed state, and the wave bead spring pushes the positioning wave bead to be clamped into the positioning hole. In the natural state, the positioning wave bead 7 can be clamped into the positioning hole 302 (i.e. when the wave bead spring 701 is not compressed, part of the positioning wave bead 7 is located outside the wave bead mounting hole 222, which facilitates clamping into the positioning hole 302).

[0140] In this embodiment, during the up and down adjustment of the mounting block 3 and the movable supporting arm 2, when the positioning wave bead 7 contacts the groove wall of the sliding groove 301, the wave bead spring 701 will be compressed and completely located in the wave bead mounting hole 222. When the positioning wave bead 7 moves to be opposite to the positioning hole 302, the positioning wave bead 7 will be clamped into the positioning hole 302 under the action of the wave bead spring 701. A plurality of positioning wave beads 7 can play a positioning role, which can ensure that the bolt 6 is aligned with and accurately inserted into the positioning hole 302. In addition, during the adjustment of the up and down positions of the mounting block 3 and the movable supporting arm 2, the cooperation of the positioning wave bead 7 and the positioning hole 302 can have a certain operation feeling during the adjustment process, and the user experience is better.
