The installation portion 15 is provided with a semi-circular groove 151 for receiving one end of the transmission shaft 13. In addition, one side of the semi-circular groove 1520 is movably provided with a The latching member 16 of the containing space 161, and the latching member 16 is protruded with a latching portion near the inner side of the base u. 162, and one end of the detent portion 162 adjacent to the transmission shaft 13 is provided with a spring 17 whose two ends abut against the seat body 11 and the detent portion 162, and the other end is provided with a lever pivoted on the seat body 11. The rotating member 18 is provided with a new manual of -6-M244102, and an eccentric shaft hole 181 is continued on the page 11 to be pivoted on the base 11 by using a latch 182. The magnet 30 is disposed in the accommodating space 161 of the detent member 16, and the magnet 30 is connected with a detent line 31 extending from the outside. Therefore, the magnet 30 can be pulled by the detent line 31. A slip is generated along the axis 5 of the transmission shaft 13, and a spring 32 is sleeved between the magnet 30 and the latch 16-the inner wall of the latch 31 to provide a latching force. The metal wheel 40 is a metal material with magnetic permeability. The metal wheel 40 has a disk portion 41. The disk portion 41 is located near the inner surface of the base body 11 and extends laterally with a ring slightly larger than the mounting portion 15. The ring 42 and a ring portion 43 provided on the periphery of the ring 42 make the cross-section of the metal wheel 40 approximately U-shaped. A through hole 44 is provided in the center of the disk portion 41 to set the metal wheel 40 on one end of the transmission shaft 13, and an end face of the transmission shaft 13 and an outer side of the through hole 44 are respectively provided with a slot 441.
