The output shaft of the drive motor 111 is provided with a drive gear 112 that meshes with an adjacent transmission gear 110.

[0025] The part to be processed is inserted and placed on the first clamping sleeve 106 of the mounting shaft 103. Then, the vertical plates 104 on both sides are driven to move towards the mounting plate 102 until the two ends of the part are pressed and clamped by the first clamping sleeve 106 and the second clamping sleeve 107 respectively. Then, the drive motor 111 on the left side can be driven, and the mounting shaft 103, the first clamping sleeve 106, the part, the connecting shaft 105 and the second clamping sleeve 107 on the left side are driven to rotate through the drive gear 112 and the transmission gear 110.
