The drive assembly consists of a transmission unit meshing with the gear body 2 and a drive unit connected to the transmission unit and capable of axially moving back and forth and enabling the gear body 2 to achieve forward and reverse rotation. The assembly frame 1 is composed of an upper plate frame and a lower plate frame connected to the upper plate frame. A plurality of protrusions 3 are provided on the end surface of the upper plate frame that protrude axially outward and are convenient for connecting to the lower plate frame. The plurality of protrusions 3 are located at At the four corners of the upper plate frame, the raised portion 3 forms an assembly cavity for the gear body 2 to be installed between the upper plate frame and the lower plate frame. The above-mentioned gear body 2 can be partially extended out of the assembly frame 1 through the gap between adjacent raised portions 3, or other connecting components can be extended into the assembly frame 1. The transmission unit is a transmission tooth 4 connected to the gear body 2. The transmission tooth 4 is connected to the gear body 2 through a connecting shaft. Both ends of the connecting shaft are connected to the upper plate frame and the lower plate frame respectively through bearings. The driving unit consists of a driving cylinder and a slider rod 5.
