The clutch 1 is assembled inside the rotary ring 2, both of them rotate around the same center shaft. The reset spring 4 is fitted inside the reset block 5 which is in turn fitted inside the reset block 3, all three rotating around the same center shaft. A projection 61 of the locating pin 6 is fitted inside the groove 51 of the reset block 5, and has a limiting role on the reset block 5 when rotating. The gear 31 of the reset block 3 engages with the gear 11 of the clutch 1, thus realizing the transmission function between the reset block 3 and the clutch 1. |
