[0031] As shown in Figure 3 , 4 ,

[0032] The transmission assembly 200 includes two rotating shafts 201 rotatably arranged on the base 100. In this embodiment, the rotating shafts 201 are fixed on the base 100 through bearings, and can rotate on the base 100.

Through the design of the sharp part 304, if the chain 102 is clamped on the teeth of the first sprocket 101 and fails to fall in time in the rotating process of the first sprocket 101, the sharp part 304 can resist the chain 102 to make it fall, thereby ensuring the normal work of the lifting mechanism.
