[0011] Preferably, a rubber pad is fixedly connected to the inner circumferential wall of the rubber sleeve, and the rubber pad is located between the two ends of the limiting groove.

[0012] Preferably, a positioning sleeve is fixedly connected to the rubber sleeve, and the end of the screw rod is rotatably arranged in the positioning sleeve.

[0013] Preferably, the end of the rubber rope is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the moving plate through a damping spring.

[0014] The above technical scheme has the following beneficial effects:

[0015] The rubber rope can be pulled by the moving plate, so that the rubber rope is in contact with the outer wall of the magnetic separation tube body, and the magnetic separation tube body is bundled, and the contact area between the rubber rope and the magnetic separation tube body is large, so that the magnetic separation tube body is not easy to be crushed or damaged.
