The circumferential angle of the interval is between 80 and 150 degrees. The first abutting portion 124 and the second abutting portion 126 are both protruded from the outer peripheral surface of the rotating core 122, so that when the rotating core 122 rotates, the first abutting portion 124 and the second abutting portion 126 can be used to abut against the triggering portions 130 on the first switch assembly 140 and the second switch assembly 150, so that the switches are triggered.

In the present embodiment, the blocking portion 128 is fixedly connected to a side wall surface of the cavity of the mounting base 110, and after the triggering structure 120 is in the first position, it can abut against the second abutting portion 126 to prevent the second abutting portion 126 from rotating clockwise, so as to prevent the first abutting portion 124 from rotating to a position between the first switch assembly 140 and the second switch assembly 150. It should be appreciated that the blocking portion 128 may also be disposed at other locations to achieve a limit, such as the downstream side of the first abutment 124 in the counterclockwise direction when the trigger structure 120 is in the second position.
