The sliding table 1 provides a limiting effect for installation of the supporting ring 71, the diameter of the top of the circular table part 11 is small, and the supporting ring 71 can be sleeved on the sliding table 1, so that the supporting ring 71 can be conveniently installed on the groove 73 of the piston 7 in the subsequent process. The top of the piston 7 is provided with a slotted hole 72, and the inserting column 13 is inserted into the piston 7 through the slotted hole 72, which helps to avoid the situation that the sliding table 1 is inclined due to stress when the supporting ring 71 slides on the outer circumferential surface of the sliding table 1, and reduces the possibility that the sliding table 1 and the piston 7 generate relative displacement. Fillet 14 has been seted up to the junction of cylindrical portion 12 and round platform portion 11 outer peripheral face, and cavity 15 has been seted up at slip table 1 top, and 1 inner peripheral face of slip table is opened relatively and is equipped with two spout 16, and spout 16 sets up along 1 inner peripheral face axial of slip table. The fillet 14 at the joint of the circular table part 11 and the cylindrical part 12 facilitates the sliding of the support ring 71 on the sliding table 1, and reduces the possibility that the rib at the bottom of the outer peripheral surface of the circular table part 11 is in contact with the inner peripheral surface of the support ring 71 to damage the support ring 71.

Referring to fig. 1 and 2, a nut 51 is inserted through the top of the connecting rod 61, two sliding bars 53 are fixed to the outer circumferential surface of the nut 51 in an opposite manner, and the sliding bars 53 are axially arranged along the outer circumferential surface of the nut 51. The bottom wall of the cavity 15 is rotatably connected with a lead screw 5, the top end of the lead screw 5 is fixed with a rotating handle 52, and the rotating handle 52 comprises a rotating disc 521 and a rotating rod 522 fixed on the top of the rotating disc 521.

Turning the handle 52 facilitates manual turning of the lead screw 5 for controlling the speed of rotation.

Referring to fig. 1 and 4, the connecting rod 61 includes a horizontal section and a vertical section connected with the horizontal section, a connecting ring 6 is fixed at the bottom of the vertical section of the connecting rod 61, an outer cylinder 31 is fixed on the inner peripheral surface of the connecting ring 6, and a spring 3 is fixed on one side of the outer cylinder 31 far away from the sliding table 1. The spring 3 is close to slip table 1 one end and is fixed with slider 21, and slider 21 is close to slip table 1 one side and is fixed with the propelling movement frame 2, and the propelling movement frame 2 shape is the rectangle frame. The pushing frame 2 drives the supporting ring 71 on the sliding table 1 to move vertically on the outer peripheral surface of the sliding table 1. The spring 3 provides the slider 21 with an elastic force returning toward the sliding table 1 when compressed, thereby providing a buffer effect for the pushing frame 2 moving away from the sliding table 1.

Referring to fig. 1 and 4, the dovetail blocks 4 are fixed to two sides of the slider 21, two dovetail grooves 41 are oppositely arranged on the inner circumferential surface of the outer cylinder 31, the dovetail grooves 41 are axially arranged along the outer cylinder 31, and the outer cylinder 31 is slidably connected with the dovetail blocks 4 through the dovetail grooves 41. The dovetail grooves 41 provide a guide function for the dovetail blocks 4 in the axial direction of the outer cylinder 31, and reduce the possibility of the slide block 21 shifting during vertical movement.
