Abstract

A chamfering knife holder includes a mounting cover, a protrusion, a mounting assembly, a first containing space, a second containing space, and a resilient element. The protrusion circularly protrudes from an internal peripheral surface of the mounting cover and is enclosed to form a through hole. The mounting assembly is detachably and movably mounted in an interior of the mounting cover. The first containing space and the second containing space are both enclosed by the mounting cover, the protrusion, and the mounting assembly and communicate with each other via the through hole. The resilient element is selectively disposed in the first containing space or the second containing space for canceling out a pushing force or a pulling force acting on a chamfering knife and prevent the chamfering knife from being damaged.
