[0034] The present embodiment provides a locking mechanism for clamping a tool, which includes a shaft component 101, a driving component 103, a clamping component 106, and a locking component 100. When clamping, it is only necessary to place the thin walls on both sides of the workpiece in the clamping groove, and then place the locking mechanism in the clamping groove. The locking component 100 is installed on the shaft component 101 and is located between the driving component 103 and the clamping component 106. The two ends of the locking component 100 are in contact with the driving component 103 and the clamping component 106 respectively.
