Similarly, the output shaft of the encoder 237 and the encoder timing pulley 242 may be engaged in this manner. Furthermore, the assembly mode of the D-shaped hole and the matching mode of the fastening bolt can be combined, and the plane presented by the D-shaped hole provides a processing clamping position for the fastening bolt. It should be noted that the D-shaped hole is a common hole for realizing the synchronous rotation of the hole shaft, and in addition, a triangular hole, a square hole, a rectangular hole and the like can all realize the same effect.

In order to protect the transmission mechanism such as gears, a shell 251 can be additionally arranged, and the shell 251 is detachably connected with the motor support 232 and the encoder support 233.
