The structure with patent number CN217121993U includes a tool rod, one end of the tool rod is fixed on the output shaft of the rotating mechanism, and the tool head is fixed at the other end of the tool rod, so that only the tool rod is retained between the driving mechanism and the tool head. Compared with the traditional technology, the power transmission deviation caused by the large number of parts is greatly reduced, thereby improving the processing accuracy and reducing the equipment cost. However, there are still areas that can be optimized in this device.
