The surface of the tool body 2 and inside the installation groove 3 is hexagonal. A third positioning groove 8 adapted to the positioning tooth 6 is opened at the top of the tool body 2. The bottom of the positioning tooth 6 is slidably clamped inside the third positioning groove 8. By providing the third positioning groove 8, the bottom of the positioning tooth 6 can pass through the second positioning groove 7 and enter the third positioning groove 8, so as to limit the tool body 2 and prevent it from falling off and moving in the installation groove 3, improving the stability of the installation of the tool body 2.

[0028] Furthermore, a second reinforcement component for reinforcing the first reinforcement component is installed outside the first reinforcement component. The second reinforcement component is slidably clamped outside the mounting seat 1; the second reinforcement component includes a clamping seat 9, which is slidably clamped outside the mounting seat 1. The top of the inner cavity of the clamping seat 9 is in contact with the top of the positioning block 5. Sliders 10 are installed on both the front and rear sides of the mounting seat 1. A chute 11 adapted to the slider 10 is opened on the inner wall of the clamping seat 9. The slider 10 is slidably clamped inside the chute 11. The clamping seat 9 is sleeved outside the mounting seat 1, which can cover and protect the positioning block 5 and the first positioning groove 4. By providing the slider 10 and the chute 11, the clamping seat 9 can be stably installed outside the mounting seat 1.
