Knife handle structure with shock absorbing function

The utility model relates to a knife handle structure with shock absorbing function. The knife handle structure is arranged between a knife handle and a mechanical spindle, wherein the mechanical spindle is provided with a mounting groove; the knife handle is provided with a clamp column correspondingly placed on the mounting groove so that the knife handle and the mechanical spindle are clamped through the clamp column and the mounting groove. In the utility model, a flexible shock absorbing ring is arranged at the periphery of the clamp column, arranged on the knife handle and surrounds the clamp column so as to fill the clearance between the knife handle and the mechanical spindle when the knife handle and the mechanical spindle are clamped and tightly contact the knife handle and the mechanical spindle. The utility model improves the shock absorbing effect of the knife handle, further completely prevents vibration caused by the rotation of the knife handle, improves the machining precision and efficiency,
