Abstract
A cold knife holder capable of pushing and pulling operations, includes a main body forming a chamber and a slot, a handle, a detent member, a first spring and a first steel ball. One side of the main body forms a perforation which communicates with the chamber. The handle includes a sleeve, a connecting rod and a grip rod. Both ends of the connecting rod are respectively connected to the sleeve and the grip rod, and the sleeve is pivotally sleeved on the main body, so that the handle is rotated relative to the main body, and the first or second caulking is connected to the perforation, and the detent member is arranged in the chamber. The first steel ball is pivotally embedded in the perforation, so that the detent member drives the first steel ball to be embedded in the first or second caulking, thereby positioning the handle.
