[0027] The anti-slip limit assembly 4 includes a screw hole column 401, a threaded half rod 1 402 is installed on one side of the screw hole column 401, and a threaded half rod 2 405 is installed on the other side, a limiting magnetic column 403 is installed on the inner side of the threaded half rod 1 402, and a limiting round nail 1 404 is installed on the outer side thereof, a magnetic limiting sleeve 406 is installed on the inner side of the threaded half rod 2 405, and a limiting round nail 2 407 is installed on the other side, the threaded half rod 1 402 is rotated into the screw hole column 401, and the threaded half rod 2 405 on the other side is rotated and screwed into the other half cavity of the screw hole column 401, when both sides are tightened, the internal limiting magnetic column 403 and the magnetic limiting sleeve 406 are adapted and limited to achieve the enhanced effect of anti-slip connection.

[0028] By replacing the original connecting piece with the current anti-drop limit assembly 4 on the device, when using the device, the double connection relationship set inside can effectively prevent the connection from falling off and loosening.

[0029] The hydraulic assembly 1 includes an oil filling port 101, which is opened on the rear side of the hydraulic pump 102. An oil outlet 103 is opened on the top of the hydraulic pump 102, and a push rod 104 is installed on the front side. A connecting block 105 is installed at the end of the push rod 104. The hydraulic pump 102 is connected to the brake assembly 3 through the connecting block 105 and the anti-drop limit assembly 4 to prevent it from falling off.

[0030] The hydraulic pump 102 drives the push rod 104 on the front side of the brake to further drive the contraction of the contraction rod 301. By controlling the contraction of the contraction rod 301, the shear assembly 5 installed at the end of the linked bending rod 302 associated therewith is controlled.

[0031] The connecting assembly 2 includes a connecting sleeve 201 , a sleeve opening 202 is provided inside the rear side of the connecting sleeve 201 , and a connecting hole 203 is installed at the front end thereof, and the sleeve opening 202 in the connecting sleeve 201 in the connecting assembly 2 is aligned with the pump body position of the hydraulic pump 102 .
