The sliding rod 37 is pushed to move in the lead screw 36 and push the first magnetic block 38 to smoothly slide into the semicircular hole 39. After the first magnetic block 38 slides into the circular groove 310 in the semicircular hole 39, the sliding rod 37 is rotated, the sliding rod 37 is rotated to drive the marker block 312 and the first magnetic block 38 to move in a ring shape, so that the marker block 312 moves in a ring shape to abut against the surface of the upper end of the arc-shaped block 313, so that the first magnetic block 38 moves in a ring shape to the inner wall of the circular groove 310 and is adsorbed in front of the second magnetic block 311.
