Problems solved by technology

[0002] The utility knife is a relatively common tool. The shape of the utility knife varies according to the design of the manufacturer, but most of the blades used in the utility knife are consistent. The blade is a thin piece, which is often easy to break. After this period, it needs to be reinstalled. When using a new blade, the existing utility knife needs to find the peripheral blade when the blade is broken, which is very troublesome

Abstract

The invention discloses an improved pen knife. The improved pen knife comprises a knife handle, a knife rest and a hanging ring, wherein the knife rest is arranged at the front end of the knife handle; the hanging ring is arranged at the rear end of the knife handle; the top and the bottom of the knife handle are provided with a convex circular curved surface respectively; the central part of each curved surface is provided with a concave anti-skid part; a notch is formed in the lateral side of the knife handle; a blade rest is arranged in the notch; a rotating shaft is matched between the blade rest and the notch; a force application notch is formed at the bottom of the notch, is positioned at one end of the notch far away from the rotating shaft and is an arc-shaped notch. Due to the blade rest, when a blade is broken, the knife rest is rotated out through the force application notch, a new blade arranged in the blade rest can be taken out and arranged, and thereby the time for looking for blades is saved for people. Meanwhile, the improved pen knife is simple in structure and is suitable for popularization.

Description

technical field [0001] The invention relates to an improved utility knife. Background technique [0002] The utility knife is a relatively common tool.
