Embodiment Construction

[0016] Hereinafter, an embodiment of the present invention will be explained with reference to the drawings.

[0017] The cutting knife of this embodiment, such as figure 1 Middle main view, figure 2 Middle side view, image 3 As shown in the middle and rear view, the blade 1 is housed in the clamp handle 2, and a tail plug 3 is attached to the clamp handle 2 to form a structure.

[0018] The chuck handle 2 has a chuck handle body 21 formed by bending a metal material into a flat C shape. A sliding groove 22 is opened on the side surface of the chuck handle body 21 in the longitudinal direction, and the front end side of the sliding groove 22 serves as a blade extension. The outlet 23 has the base end side as the blade insertion port 24. On one of the opposing edge portions located on both sides of the sliding groove 22, a stopper uneven portion 25 is formed at a predetermined pitch. Furthermore, in the aforementioned sliding groove 22, the slider 4 is inserted from the blade in...

Abstract

To provide a cutter knife which prevents broken blade pieces from being scattered to unexpected places and from losing sight of these pieces and eliminates the botheration of assuring a suitable place for disposal, etc. The cutter knife is provided with a holder 2 for housing blade bodies 1 and a blade body breaker X disposed in part of the holder 2 for breaking part of the blade bodies 1, in which the blade breaker X is provided with a cavity S for taking in the separated blade piece 1b in breaking and for keeping the blade piece to house therein.

Description

Technical field [0001] The present invention relates to a cutting knife widely used as office supplies, stationery, and the like. Background technique [0002] The cutting knife, as well known, has a blade that connects a plurality of blades, and becomes an unnecessary part that breaks if the sharpness of the blade deteriorates, and new blades can be sent out one after another for use. Moreover, in order to break the blade, a slit is usually provided on the tail plug of the main body to function as a blade breaking device. The tail plug is removed and the slit is placed on the blade, and the tail plug is forced at its position to break it. Unwanted blade. [0003] However, the broken blades are easily scattered to unexpected places and lost. Even if they are not scattered but there is no suitable place around them to be discarded, it is often difficult to dispose of them. [0004] Therefore, it is desirable to prepare an environment where you can concentrate on the work without p...
