Furthermore, a rotating clamp block 3 is mounted on the rotating shaft 2b, and then a plurality of protruding fixing teeth 4 are arranged on the side surface of the clamp block 3, so that when the object is clamped, the side surface of the clamp block 3 is close to the object to be conveyed, and the fixing teeth 4 on the side surface of the clamp block are pressed on the object to be conveyed, and the object can be lifted.
Therefore, the utility model also has a force application mechanism which leads the clamping block to clamp the object to be carried. Specifically, the legs 2a of two different herringbone rods 2 are connected through a pre-tightening spring 6, so that the conveyed object can be clamped by the elasticity of the spring. Then, a lifting rope 5 is connected with the support legs 2a of two different herringbone rods 2 in a sliding mode, meanwhile, the lifting rope 5 is connected with the support legs 2a of the herringbone rods 2 in a sliding mode, when the lifting rope 5 is stressed, a clamping force which is close to each other is exerted on the two connected support legs 2a, the larger the stress of the lifting rope 5 is, the larger the clamping force is, the stress of the lifting rope 5 comes from the self weight of the object to be conveyed, the friction force between the fixed teeth 4 on the clamping block 3 and the object to be conveyed is transmitted to the lifting rope 5, the object to be conveyed is clamped by the self weight of the object to be conveyed, and then the object is lifted.
