[0024] By opening a mounting groove 4 on the support arm 2 on the claw seat 1, the mounting block 5 outside the claw 3 can be quickly inserted into the mounting groove 4 to form a pre-fixation, and then a sliding sleeve 8 that can move laterally installed inside the support arm 2 can be used to push the push block 12 at the top of the sliding sleeve 8, so that the sliding sleeve 8 drives the two groups of side insertion rods 9 to move laterally along the sliding rod 7, so that the two groups of side insertion rods 9 can be quickly inserted into or leave the side insertion rods 9 at the lower end of the mounting block 5 under the drive of the sliding sleeve 8, so that the two groups of side insertion rods 9 can quickly form or release the movable limiting effect on the mounting block 5, thereby facilitating the rapid installation and disassembly of the claw 3 as a whole, thereby improving the convenience of the device when used.

[0025] In other embodiments, the top outer wall of the push block 12 and the top outer wall of the support arm 2 are located in the same horizontal plane;

[0026] Through this design, the push block 12 can be completely received into the top groove 11 .

[0027] In other embodiments, guide slots 13 are provided on both sides of the support arm 2, and guide sliders 14 are slidably connected in the two sets of guide slots 13. Sheaths 15 are fixed to the outside of the two sets of guide sliders 14, and a push plate 16 is fixed to the top of the sheath 15. The sheath 15 can be moved to the top of the top slot 11. Second springs 18 are installed inside the two sets of guide slots 13, and the two sets of guide sliders 14 are elastically connected to the inner wall of the guide slot 13 through the second springs 18.

[0028] By installing a laterally movable cover 15 on the outside of the support arm 2, the push plate 16 outside the cover 15 can be pushed, so that the cover 15 drives the two sets of guide sliders 14 to move laterally along the guide slide groove 13, and under the elastic force of the two sets of second springs 18, the cover 15 can be moved to the outside of the top groove 11, forming an effective sealing effect on the inside of the top groove 11, avoiding the outside from accidentally touching the push block 12 inside the top groove 11, and preventing foreign objects from entering the top groove 11.

[0029] In other embodiments, the interior of the sliding sleeve 8 is fully fitted with the outer wall of the sliding rod 7, and the sliding sleeve 8 is slidably connected to the sliding rod 7;

[0030] With this design, when the sliding sleeve 8 moves laterally along the sliding rod 7, it can effectively prevent the sliding sleeve 8 from causing the side insertion rod 9 to shake, thereby ensuring that the two groups of side insertion rods 9 can move smoothly.

[0031] In other embodiments, multiple sets of anti-slip grooves are provided on the top groove 11;

[0032] Through this design, the friction between the top groove 11 and the user's hand can be effectively increased, which facilitates the effective lateral pushing of the top groove 11.

[0033] In other embodiments, two ends of the first spring 17 are respectively connected to the outer wall of the sliding sleeve 8 and the inner wall of the movable inner cavity 6, and the sliding sleeve 8 is elastically connected to the inner wall of the movable inner cavity 6 through the first spring 17;

[0034] With this design, when the first spring 17 can exert a continuous elastic force on the sliding sleeve 8 toward the installation slot 4 , the sliding sleeve 8 can drive the two sets of side insertion rods 9 thereon to be quickly inserted into the installation slot 4 .

[0035] In other embodiments, a sealing rubber sleeve is installed on the inner wall of the sheath 15;

[0036] Through this design, the gap between the inner wall of the sheath 15 and the outer wall of the push block 12 can be effectively reduced. When the sheath 15 moves to the outside of the top groove 11, foreign matter can be effectively prevented from entering the top groove 11.

[0037] The electrical components mentioned in this article are all connected to an external main controller and industrial power supply, and the main controller can be a conventional known device for control such as a computer.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
