[0002] A chain block includes a hoisting chain and a hand-pulling chain. By pulling the hand-pulling chain, the long shaft is driven to rotate, and then the torque is transmitted to the hoisting chain through the long shaft, so as to lift the heavy object.

[0003] In the prior art, Chinese Patent Publication No. CN213018358U discloses a chain block housing and a chain block. The chain block housing includes a housing body, and the housing body is provided with a plurality of connection structures for fixedly connecting the housing body with the chain block main body, and the connection structures are symmetrically distributed along the axial direction of the long shaft of the chain block. The utility model can solve the problem of single application of traditional hoists, and at the same time can reduce the problem that the chain block with a movable structure is prone to jamming.

[0004] However, when the utility model is actually used, the staff pulls the hand-pulling chain by hand, and the hand-pulling chain rubs against the hand. At the same time, the staff needs to pull the hand-pulling chain with force. Therefore, after a long time of work, it is more labor-consuming, and the hand is easily damaged by the friction of the chain. Therefore, an auxiliary device for a chain block is needed. Summary of the Utility Model
