[0025] A placement plate 2 is arranged on the top of the base 3, and a placement groove 13 is provided inside the upper surface of the placement plate 2, and a connecting installation groove 15 is provided at the bottom of the placement groove 13, and a magnetic suction cup 14 is installed inside the installation groove 15, and an installation box 1 is arranged on both sides of the placement groove 13 on the top of the placement plate 2, and a transmission mechanism 5 is arranged inside the installation box 1, and the transmission mechanism 5 includes a hand wheel 501, and the hand wheel 501 is rotatably arranged on the top of the installation box 1, and the bottom of the hand wheel 501 is fixedly connected to a worm 502 through a rotating rod, and the outer wall of the worm 502 is transmission-connected to a worm wheel 507, and the inside of the worm 502 is fixedly connected There is a rotating rod 506, one end of which is fixedly connected to a bidirectional screw 510, and a moving block 509 is threadedly connected to the outer wall of the bidirectional screw 510, and a limit rod 508 is movably provided on the surface of the moving block 509, and the two moving blocks 509 are fixedly connected to the second hinge blocks 505 on the sides close to each other, and the two second hinge blocks 505 are hinged to the connecting rod 504 on the sides close to each other, and the two connecting rods 504 are hinged to the first hinge blocks 503 on the sides close to each other, and the first hinge blocks 503 are fixedly connected to the outer wall close to the clamping plate 4, and the clamping plate 4 is provided on the sides close to each other of the two installation boxes 1; Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, when the hydraulic cylinder needs to be clamped and fixed, the hydraulic cylinder is placed in the placement groove 13. At this time, the bottom of the hydraulic cylinder can be adsorbed and pre-fixed by the magnetic suction cup 14, and then the two hand wheels 501 are rotated respectively. The rotation of the hand wheel 501 drives the worm 502 to rotate through the rotating rod. The rotation of the worm 502 drives the rotating rod 506 to rotate through the worm gear 507. The rotation of the rotating rod 506 drives the bidirectional screw 510 to rotate. The rotation of the bidirectional screw 510 drives the two second hinge blocks 505 to move in a direction away from each other. The movement of the two second hinge blocks 505 is achieved through the cooperation between the first hinge block 503 and the connecting rod 504. The two clamping plates 4 are driven to move in a direction approaching each other until they come into contact with the outer walls of both sides of the hydraulic cylinder and are effectively clamped and fixed. Through the cooperation between the worm 502 and the worm wheel 507, a self-locking effect can be achieved, thereby effectively ensuring the stability of the hydraulic cylinder after clamping, and thus ensuring the processing effect of the hydraulic cylinder in the later stage. This solves the problem that the second threaded rod 907 is prone to rotation during actual use due to the lack of a mechanism to limit the second threaded rod 907, thereby making it difficult for the two clamping plates 4 to effectively clamp the hydraulic cylinder, which will affect the later processing of the hydraulic cylinder and result in poor use effect.

[0026] The four corners of the bottom of the base 3 are equipped with moving wheels 7, and both sides of the base 3 are fixedly connected with fixed plates 11. The surface of the fixed plate 11 is provided with a threaded limit screw 8, and the bottom of the limit screw 8 is fixedly connected with a limit pad 12; Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when in use, the sliding property of the moving wheel 7 can be used to facilitate position adjustment of the device, and when the device is moved to a suitable position, the limiting screw 8 can be rotated, and the limiting screw 8 rotates to drive the limiting pad 12 to move downward until it contacts the placement surface. The limiting pad 12 can increase the friction with the placement surface, thereby effectively preventing the moving wheel 7 from moving and improving safety.

[0027] Working principle: In the present application, first, when the hydraulic cylinder needs to be clamped and fixed, the hydraulic cylinder is placed in the placement groove 13. At this time, the bottom of the hydraulic cylinder can be adsorbed and pre-fixed by the magnetic suction cup 14, and then the two hand wheels 501 are rotated respectively. The rotation of the hand wheel 501 drives the worm 502 to rotate through the rotating rod. The rotation of the worm 502 drives the rotating rod 506 to rotate through the worm gear 507. The rotation of the rotating rod 506 drives the bidirectional screw 510 to rotate. The rotation of the bidirectional screw 510 drives the two second hinge blocks 505 to rotate along each other. The two second hinge blocks 505 move in the direction away from each other, and the two second hinge blocks 505 move through the cooperation of the first hinge block 503 and the connecting rod 504, driving the two clamping plates 4 to move in the direction of approaching each other until they contact the outer walls of both sides of the hydraulic cylinder and effectively clamp and fix them. The mutual cooperation of the worm 502 and the worm wheel 507 can achieve a self-locking effect, thereby effectively ensuring the stability of the hydraulic cylinder after clamping, and then ensuring the processing effect of the hydraulic cylinder in the later stage. Secondly, it can drive the close contact through the output end of the forward and reverse motor 10 A threaded rod 907 close to the forward and reverse motor 10 rotates, and the threaded rod 907 rotates and drives another threaded rod 907 away from the forward and reverse motor 10 to rotate through the transmission rod 905. The two threaded rods 907 rotate and drive the two threaded blocks 903 to move. The movement of the two threaded blocks 903 drives the two fourth hinge blocks 906 to move. The two fourth hinge blocks 906 move through the cooperation of the third hinge block 904 and the transmission rod 905, and drive the placement plate 2 to move. The movement of the placement plate 2 finally drives the hydraulic cylinder to move. By facilitating the reasonable adjustment of the height position of the hydraulic cylinder, it is convenient to better meet the processing requirements of different scenes, thereby improving the convenience of the device. Finally, the sliding property of the moving wheel 7 can be used to facilitate the position adjustment of the device, and when the device moves to a suitable position, the limiting screw 8 can be rotated, and the limiting screw 8 drives the limiting pad 12 to move downward until it contacts the placement surface. The friction with the placement surface can be increased by the limiting pad 12, thereby effectively preventing the moving wheel 7 from moving and improving safety.
