[0011] Further, the bottom of the tapered block is uniformly provided with a plurality of limiting grooves around the axis, and the tapered block is movably connected with the plurality of limiting pins through the plurality of limiting grooves.

[0012] Further, the top of the tool bit is fixedly connected with the bottom of the tapered block through the tool bit fixing sleeve.

[0013] Compared with the prior art, the tool bit fixing sleeve of the utility model has the advantages that:

[0014] The utility model discloses a tool bit fixing sleeve, which clamps the tapered block on the top of the tool bit, and then the tool bit fixing sleeve and the handle top are tightened, thereby the tapered block is tightly pressed, the tool bit is prevented from shaking, the tool bit fixing sleeve is fixed with the handle through the bolt, the tool bit fixing sleeve is prevented from loosening, different tool bits can be quickly replaced, the tool bit is firmly fixed, and the use effect is guaranteed.
