摘要:
A cartridge-type chuck for use in a dental handpiece wherein a substantially cylindrical cartridge case incorporates within itself at least a friction-type chuck body and a stopper provided with a square hole of a smaller diameter than the inner diameter of said chuck body, said cartridge case being formed at its front part into truncated cone by tapering the outer circumferential surface and is provided at its thickened rear part with a threaded interface on the circumference, is disclosed. This cartridge-type chuck is able to be loaded and unloaded for the purpose of replacing it with ease in relation to the rotor disposed in the inside of a dental hand-piece, into which the dental cutting tool can be inserted by a single step, and whose holding power is strong enough to be free from occurrence of the center whirling of the spindle of said cutting tool.
