The mounting structure 10 comprises a mounting plate 11 and a suction accessory 12 connected with the mounting plate 11. The lifting piece 20 is movably threaded on the mounting plate 11. The first driving piece 30 is rotatably arranged on the mounting plate 11 and drivingly cooperates with the lifting piece 20, and the relative position between the first driving piece 30 and the mounting structure 10 in the axial direction of the lifting piece 20 remains unchanged. The pulling assembly 40 comprises a first pulling piece 41, a second pulling piece 42, and a second driving piece 43, the first pulling piece 41 and the second pulling piece 42 are swingably connected with the lifting piece 20, and the second driving piece 43 is movably arranged along the axial direction of the lifting piece 20 and drivingly cooperates with the first pulling piece 41 and the second pulling piece 42. Among them, the second driving piece 43 drives the first pulling piece 41 and the second pulling piece 42 to switch between the outer swing pulling position and the recycling avoidance position, when the first pulling piece 41 and the second pulling piece 42 are both in the outer swing pulling position, the distance between the contact position of the first pulling piece 41 with the bushing 1 and the contact position of the second pulling piece 42 with the bushing 1 is greater than the inner diameter of the bushing 1.
