Description

A kind of cutter

Technical field

The utility model relates to a kind of cutter.

Background technology

There is a kind of cutter mainly to comprise housing in the market in the cutter of Xiao Shouing, be provided with knife rest in the housing and go out the edge of a knife, what knife rest was provided with shape and blade coupling puts the cutter groove, put in the cutter groove blade is set, blade is provided with the screens groove, the screens projection also is equipped with on the knife rest, the screens projection is equipped with control button, blade is arranged on that the screens projection on the knife rest is stuck in the screens groove of blade when putting in the cutter groove, the screens projection can fluctuate, and snaps in and breaks away from screens groove on the blade by screens projection unsteady.But the screens projection of this cutter and control button thereof must could be provided with on cutter possesses the basis of bigger thickness, so above-mentioned screens projection and control button thereof just are difficult to reach requirement when producing the portable cutter of thinner thickness.

Summary of the invention

The purpose of this utility model provides a kind of cutter, and the control button that promotes this cutter along the knife rest flat transverse can be controlled the screens projection and snap in and break away from screens groove on the blade.

For this reason, the cutter that the utility model provides mainly comprises housing, be provided with knife rest in the housing and go out the edge of a knife, knife rest is provided with puts the cutter groove, put in the cutter groove blade is set, offer the screens groove on the blade, the screens projection also is equipped with on the knife rest, the screens projection is equipped with control button, knife rest is provided with locking lever, screens projection and control button are separately positioned on the two ends of locking lever, are rotationally connected by pin between locking lever and the knife rest, and the tie point of locking lever and knife rest is between control button and screens projection; Locking lever is equipped with back-moving spring, and an end of back-moving spring withstands on pin on the locking lever to the position between the locking lever rear end face, and the other end withstands on the knife rest.

Because the knife rest of the utility model cutter is provided with locking lever, there is pin to be connected between locking lever and the knife rest, and the two ends of locking lever are respectively arranged with control button and screens projection, therefore promote or the control button that unclamps this cutter just can be controlled the disengaging of screens projection or snap in screens groove on the blade along the knife rest flat transverse, the control mode that the screens projection moves relative to the knife rest flat transverse is compared control mode that the screens projection fluctuates the requirement of cutter thickness is reduced greatly.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, the utility model cutter mainly comprises housing 1, be provided with knife rest 2 in the housing 1 and go out the edge of a knife 3, knife rest 2 is provided with puts cutter groove 4, put blade 5 is set in the cutter groove 4, offer screens groove 6 on the blade 5, screens projection 7 also is equipped with on the knife rest 2, screens projection 7 is equipped with control button 8, control button 8 can be the triangle metal piece that has the inclined-plane, the inclined-plane of control button 8 is provided with tread plate, knife rest 2 is provided with locking lever 9, screens projection 7 and control button 8 are separately positioned on the two ends of locking lever 9, be rotationally connected by pin 10 between locking lever 9 and the knife rest 2, pin 10 passes the through hole 14 that is arranged on the locking lever 9 and is connected with knife rest 2, so locking lever 9 can rotate around pin 10 relative to knife rest 2, and the tie point of locking lever 9 and knife rest 2 is between control button 8 and screens projection 7; Locking lever 9 is equipped with back-moving spring, and an end of back-moving spring withstands on pin 10 on the locking lever 9 to the position between locking lever 9 rear end faces, and the other end withstands on the knife rest 2.The screens groove 6 that the screens projection 7 of locking lever 9 front ends is broken away from the blades 5 in the present embodiment as the user, locking lever 9 is subjected to the thrust of back-moving spring that screens projection 7 is snapped in the screens groove 6 again when unclamping control button 8, so the user can realize that blade 5 is from going out the dismounting of the edge of a knife 3 by promoting control button 8.

As Fig. 3, Fig. 4, Fig. 6, shown in Figure 7, offer lock slots 11 between housing 1 of cutter the first half and the knife rest 2, the form fit of the shape of lock slots 11 and locking lever 9, locking lever 9 places lock slots 11.The inwall of lock slots 11 only is subjected to spring thrust to do the time spent at locking lever 9 in the present embodiment, and the front end that stops locking lever 9 enters to be put in the cutter groove 4, and locking lever 9 can be fixed in residing position.

As Fig. 2, Fig. 4, shown in Figure 7, can be under the situation that need not promote control button 8 directly to pack into the cutter in order to make blade 5 from going out the edge of a knife 3, screens projection 7 is rounded down towards a side that goes out the edge of a knife 3, perhaps is provided with the inclined-plane.
