The bolt passes through the deformation block 24 and connects to the tool holder body 21. The operator can tighten or loosen the bolt to press or release the deformation block 24. When the tool locking component 4 is tightened, the deformation block 24 presses against the tool mounting bracket 3, making the tool mounting bracket 3 and the tool holder body 2 securely fitted. When it is necessary to adjust or remove the height of the tool, the tool locking component 4 is loosened, causing the deformation block 24 to release the tool mounting bracket 3. At this time, the height of the tool mounting bracket 3 can be adjusted or the tool mounting bracket 3 can be removed. In this way, the operator only needs a screwdriver to quickly complete the adjustment or removal of the tool mounting bracket 3. The structure is simple and easy to use.
