The cylinder body of the lifting cylinder 61 is fixed on the base block 4. The piston rod of the lifting cylinder 61 is fixed with a magnetic rod 62 for magnetically attracting the steel ball. The magnetic rod 62 is placed in a straight hole of the base block 4, and the diameter of the straight hole is smaller than the diameter of the steel ball.

[0024] A pressure rod 10 for pressing the steel ball is installed on the base block 4.

[0025] The pressure rod 10 is slidably connected to the base block 4, and a spring is connected between the base block 4 and the pressure rod 10. The spring can provide a buffer for the pressure rod 10 to avoid hard contact with the steel ball.
