The end of the driver (13) is provided with a gear, and the gear is connected to the sawtooth position of one side of the vertical magnetic suction rod (21).

[0037] The sawtooth position on the other side of the magnetic rod (21) is connected to the fixed free-rotating gear (15) in the rust-proof and electric shock-proof metal shell (6) to reduce the vertical movement resistance of the magnetic rod (21).
