Abstract

The utility model relates to an art designing knife which is provided with a blade (1) and a handle (16). The utility model is characterized in that the blade is arranged on a knife frame (9) hinged with the handle. The rear side part of the knife edge of the blade is imbedded in a blade groove (26) on one side of the knife frame. The back side of the blade is connected with a locking strip (4). The utility model has a connecting structure that the middle part of the locking strip (4) is hinged with the knife frame by a locking strip axis (5), a convex locking head (3) arranged at the front part is imbedded in a concave positioning slot (2) on the back side of the blade, the back part is provided with an elastic depressing switch (6) of the locking strip, and elastic locking components (12, 20) are arranged between the hinged knife frame (9) and the handle (16). Both ends of each art designing blade of the utility model both can be used. A non-serviceable part need not to be left in the knife frame, and thus, the using rate of the blade is high. The utility model has the advantages that replacement is convenient and the utility model is hard to rupture.

Description

A kind of cutter

Technical field

The utility model belongs to a kind of cutter, is specifically related to a kind of cutter of changeable blade.

Background technology

Common cutter blade is to be combined by multi-disc unit art designing's blade, with blunt one section, get rid of again with next section, every blade can only can not use near the point of a knife of breaking a disconnected side off with the fingers and thumb, and use end with a side tool point, remainder length is stayed in the knife rest always, the blade utilization rate is not high, and long blade in use also fractures easily, and the blade exchange trouble.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of utilization rate height, and it is convenient to change, the cutter of frangibility not in the use.

The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with blade (1), handle (16), it is characterized in that: described blade is contained on the knife rest hinged with handle (9), the blade rear flank portion of blade embeds in the insert groove (26) of knife rest one side, knife back side is connected with bolt (4), its syndeton is: bolt (4) middle part is hinged by bolt axle (5) and knife rest, the anterior protruding tapered end (3) that is provided with embeds in the recessed locating slot (2) of knife back side, the rear portion is provided with bolt elasticity depress switch (6), be provided with elastic locking part (12,20) between hinged knife rest (9) and the handle (16).

Using method of the present utility model is: unit art designing's blade (1) is contained on the knife rest (9), the blade side of blade embeds in the insert groove (26) of knife rest, the knife back is embedded into bolt tapered end (3) location of its detent, blade is with after blunt, depress bolt (4) rear end by elasticity depress switch (6), the tapered end of bolt front portion (3) breaks away from knife back locating slot (2), can take off blade (1), be installed in again on the knife rest after turning over turnback, promptly can use the blade other end; Knife rest is locked in open mode with handle (16) by elastic locking part (12,20) under user mode, can open elastic locking part (12,20) after using up, and blade holder turns is recovered in the handle (16).

Every art designing's blade two ends of the present utility model all can be used, must be in knife rest residual out of use part, so blade utilization rate height, and have change convenient, the advantage of frangibility not.

The specific embodiment

Embodiment 1

This routine knife rest 9 is connected with handle 16 hinges, trapezoidal art designing's blade 1 bottom blade rear flank portion embeds in the insert groove 26 of knife rest, top knife back side is provided with recessed locating slot 2, hinged with bolt 4 middle parts of insert groove 26 almost parallels by jointed shaft 5 and knife rest, the anterior protruding tapered end that is provided with 3 embeds in the locating slot 2 of the knife back, elasticity depress switch 6 structures that the rear portion is provided with are: bolt rear portion outward direction is stuck on the limited step of knife rest 9, back-moving spring 7 is housed between inward direction and the knife rest, when inward direction is depressed, bolt 4 promptly can rotate along hinge axis 5, lift its front portion, breaks away from the locating slot 2 of the knife back, takes off blade.

Knife rest 9 is connected with handle 16 hinges by hinge axis 10, elastic locking part structure between the two is: elastic locking switch 12 rear portions that are provided with on the handle 16 are fixed on the handle of a knife 16 by spring and spring fixed axis 14, anterior spring leaf 15 elasticity are withstood the knife rest positioning table 11 that knife rest 9 is positioned at hinge axis 10 downsides, the alignment pin 8 that is provided with on the handle 16 is withstood at the knife rest position that is positioned at the hinge axis upside, thereby can circumferential locking knife rest and handle 16 remain on the state of opening and using, when needing to regain knife rest, depress elastic locking switch 12, spring leaf 15 breaks away from the knife rest positioning table 11 of knife rest 9, knife rest 9 can rotate along hinge axis 10, go back in the handle 16, avoid blade to expose and hurt sb.'s feelings, guarantee safety.

Handle 16 rear portions are provided with belt fastener, are used for fixing on belt, are easy to carry.

Embodiment 2

This routine knife rest 9 is connected with handle 16 hinges by hinge axis 10, elastic locking switch 20 structures of the setting between the two are: back of the body bar 18 middle parts are supported on handle 16 backs by bearing pin 19, the tapered end 17 of the anterior projection that is provided with of back of the body bar embeds in the knife rest locked groove 21 that is provided with on the knife rest 9, back-moving spring 23 is housed between rear portion and the handle, back-moving spring is V-shaped, the middle part is enclosed within on the bearing pin 19, and a rear flank end and spring base 24 are fixing, and the open opposite side of elasticity is connected with back of the body bar rear portion.Elasticity is depressed back of the body bar rear portion, and its anterior tapered end 17 breaks away from the locked groove 21 of knife rest, and knife rest 9 is promptly rotatable to be regained in the handle 16; When opening knife rest, first elasticity is depressed back of the body bar rear portion 20, resets again, and tapered end 17 elasticity are embedded in the knife rest locked groove 21, can lock knife rest it can not be rotated.
