[0011] Preferably, a copper sheet is welded on the side wall of the recess near the side of the base circle center, and the connecting head abuts against the copper sheet, and the copper sheet contacts the outer end of the corresponding heat dissipation groove.

[0012] The technical scheme has the advantages that when the tool head works, a large amount of heat is generated, the heat is transmitted from the connecting head to the copper sheet because the copper sheet contacts the connecting head, the heat on the copper sheet is dissipated by the heat dissipation groove, and the heat dissipation efficiency is improved.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] (1) The tool head is fixed in the recess through bolts, the installation and replacement of the tool head are facilitated, and maintenance is facilitated.

[0015] (2) When the tool head works, the heat generated by the tool head is quickly dissipated through the heat dissipation groove, and the heat dissipation effect is improved. BRIEF DESCRIPTION OF DRAWINGS
