Subsequently, the tool seat 1 can be easily detached from the connecting seat 4, so as to facilitate replacement of the new tool head body 3. In addition, the anti-skid lines 15 arranged on the outer wall of the tool seat 1 can increase the holding stability of the tool seat 1 by the operator, and reduce the risk of slipping during replacement of the tool head body 3. When the tool head body 3 works, the inner wall of the connecting block 2 and the inner wall of the tool head body 3 are connected with the heat dissipation pipe 13, and the cooling water in the heat dissipation pipe 13 can effectively absorb the heat generated by the tool head body 3. The cooling water enters the heat dissipation pipe 13 through the water inlet pipe 11 and is discharged through the water outlet pipe 14 after absorbing heat, so as to realize continuous cooling of the tool head body 3. This cooling mode not only improves the working efficiency of the tool head body 3, but also prolongs the service life of the tool head body 3.
