couple

8, and 8 tops of couple are provided with the space ring, and the split pin is inserted at 7 tops of pivot, 8 last reset torsion springs 9 that have cup jointed of couple, 9 one end of reset torsion springs are fixed in the draw-in groove 802 of 8 joint portion 801 lateral walls of couple, and the 9 other end of reset torsion springs is fixed on the space ring of cam 3 below. The clamping part 801 of the hook 8 is matched with the limiting groove 302 on the side wall of the cam 3. The long shaft 10 horizontally penetrates through holes in two sides of the installation bottom plate, a spacer ring is sleeved between the left end of the long shaft 10 and the through holes, the spacer ring is sleeved at the right end of the spacer ring, a gasket ring is sleeved at the right end of the spacer ring, a second gear 11 is sleeved at the right end of the gasket ring, a split retainer ring is sleeved at the right end of the gasket ring, a spacer block 12 is sleeved at the right end of the split retainer ring, the spacer ring is sleeved at the right end of the spacer block, a retainer ring is sleeved at the right end of the spacer ring, and the right end of the long shaft extends.
