its design principle utilizes stretcher strain and spindle taper hole crimp when being and handle of a knife being loaded main shaft, and handle of a knife hypomere is reduced, and along with the increase of pulling force, handle of a knife epimere also becomes to fit with main shaft is capable reliably.

in order to reach above-mentioned goal of the invention, the 3rd technical scheme that the utility model adopts is: the cone angle of the male cone (strobilus masculinus) that handle of a knife contacts with spindle taper hole is less than or equal to the cone angle of spindle taper hole slightly; Handle of a knife center is processed with the taper hole that a cone angle is less than or equal to handle of a knife male cone (strobilus masculinus); Blind rivet connects with the little conical surface end of handle of a knife.

its design principle utilizes stretcher strain and spindle taper hole crimp when being and handle of a knife being loaded main shaft, makes handle of a knife realize bump contact.

for better ensureing that the large conical surface end of handle of a knife can reliably be fitted with spindle taper hole, the male cone (strobilus masculinus) mid portion of handle of a knife grinds little.

the beneficial effects of the utility model are: the contact area of handle of a knife and main shaft is large, rigidity strong, and vibration-damping effect improves; Owing to being the large conical surface and all good the fitting with main shaft of energy of little conical surface end of handle of a knife, its leverage effects is good, and when particularly installing major axis cutter, the swing of point of a knife is little, and rigidity is strong; The minimizing of beating of its handle of a knife in High-speed machining, repeats tool changing precision and improves.
