Problems solved by technology

Most of the existing utility knives have a pull-out structure. When the blade is used up, the blade needs to be retracted and stored. However, when the existing utility knife uses the blade to cut objects, the blade is easy to move and the stability is not high. When retreating, the thumb needs to be pushed and pulled with greater strength, and the operation is more laborious

Abstract

The invention discloses an art knife. The art knife comprises a knife handle, a sliding component and a blade, wherein the knife handle comprises a holding part with an accommodating space inside andan opening at one end, a transverse through sliding path is arranged on the holding part, an outward notch is formed in a place, corresponding to opening end of the holding part, of the sliding path,and positioning grooves are arranged on one side of the sliding path; the sliding component comprises a sliding sheet which is arranged in the accommodating space and capable of sliding along a longitudinal direction, and a positioning piece of which one end is rotatably connected to the sliding sheet and the other end can be matched with the positioning groove through rotation; one end of the blade is detachably fixed on the sliding sheet, and the other end of the blade can extend out of the opening end of the holding part. The problem of labor waste and inconvenience when the blade is pushedout or retracted can be solved, the stable work of the blade can be guaranteed so that the blade cannot move, the smoothness of the manual push-pull can be guaranteed, and the operation is easy.
