[0021] To further optimize the above technical solution, the support structure includes a reinforced support sleeve 4, which is arranged on one side of the bearing 3 and is used to relieve the impact force during the use of the chain block.

[0022] Specifically, the housing 1 is the outer shell of the chain block, which is convenient for protecting the internal structure of the chain block and increasing its service life. The bracelet wheel cover 2 is thickened to ensure that there is enough space for installing the bearing 3. Moreover, a groove for installing the bearing 3 is machined on the bracelet wheel cover 2.
