This facilitates the adjustment of the position of the tool head 10. When adjusting the position of the tool head 10, the position support of the tool head 10 is achieved through the cooperation of the first connecting rod 14 and the second telescopic rod 16. The second spring 17 provides a restoring force to ensure that the second telescopic rod 16 can maintain the stability of its current position when it is not subjected to external force. The sliding range of the connecting seat 6 is limited by the baffle 11 to prevent it from sliding excessively. To prevent positioning errors or equipment damage, ensure the stable position of the cutter head 10, regularly check whether all connecting parts are tight, especially the shaft connection between the first connecting rod 14 and the second mounting seat 15, check whether the second spring 17 is intact and ensure that it can provide sufficient restoring force, regularly clean the inside of the cutter holder box 1, ensure smooth sliding between the baffle 11 and the connecting seat 6, clean the cutter head 10 and the connecting seat 6 to ensure machining accuracy, lubricate the rotating connection to ensure that the first connecting rod 14 and the second telescopic rod 16 can rotate smoothly, lubricate the screw 9 to ensure that it will not jam during adjustment.
