more specifically, because the first gear 33 is meshed with the second gear 331, and the coil spring is installed on the rotating rod of the second gear 331, the second gear 331 is driven to rotate in the process of rotating the first gear 33, the coil spring is gradually tightened when the second gear 331 rotates, so after the hook 41 is inserted into the circular groove of the precast floor slab, the coil spring wants to drive the second gear 331 to restore, the second gear 331 wants to drive the first gear 33 to restore, and the first gear 33 wants to drive the hanging rod 35 to restore, so that the force of the hook 41 clamped in the circular groove of the precast floor slab can be increased, and the precast floor slab can be better lifted.
Embodiment four:
Two lantern rings 42 are connected to the cross rod 4 in a sliding manner; the hook 41 rotates on the collar 42;
in this embodiment, a fourth spring 43 is fixedly connected to opposite sides of the two collars 42 on each cross bar 4;
Specifically, in the process of inserting the hooks 41 into the circular grooves of the precast floor slabs, at this time, the two lantern rings 42 are manually controlled to move to the opposite sides, the fourth springs 43 are elongated in the process of moving the two lantern rings 42, when the hooks 41 are opposite to the circular grooves on the precast floor slabs, the hooks 41 are inserted into the circular grooves, and the fourth springs 43 are in the elongated state, so that the hooks 41 want to drive the lantern rings 42 and the hooks 41 to restore to the original state, and because the hooks 41 are already inserted into the circular grooves of the precast floor slabs, the two hooks 41 can be clamped in the circular grooves of the precast floor slabs, so that the effect of clamping the hooks 41 in the circular grooves of the precast floor slabs can be further improved, and the precast floor slabs can be well hoisted.
