[0020] The connecting seat 1 is provided with symmetrically distributed cooling grooves 3, and the cutting tool 11 and the chamfering tool 12 are movable in the cooling grooves 3. A cooling pipe 31 is installed in the connecting seat 1. The cooling pipe 31 is wound around the outside of the cutting tool 11 and the chamfering tool 12, and connecting sleeves 32 are installed at both ends of the cooling pipe 31.

[0021] By adopting the above technical solution, the coolant is transmitted through the cooling pipe 31, and the cutting tool 11 and the chamfering tool 12 are cooled in the cooling tank 3, thereby avoiding the problem of deformation of the cutting tool 11 and the chamfering tool 12 due to excessive temperature.

[0022] Screw rods 14 are threadedly inserted on both sides of the connecting seat 1 , and an extrusion block 15 is rotatably provided at one end of the screw rod 14 close to the connecting seat 1 .
