Abstract

The utility model discloses a paper knife, which features simple lockup structure, convenient open and comfort. The paper knife comprises a knife blade, a knife bed and a knife handle. The knife bed is riveted on the knife handle and characterized in that a through hole is available at the position where the knife bed and the knife blade form a concave chute. Also, an appropriate dowel pin is available for the through hole.

Description

A kind of paper knife

Technical field

The utility model relates to five metals cutter class and makes the field, more particularly is a kind of paper knife of changeable blade.

Background technology

Paper knife is a cutting tool relatively more commonly used, generally is used for the cutting of paper, cloth, plastic or other material.Now the paper knife of selling on the market generally is made up of blade, tool rest and handle of a knife, and blade is positioned in the tool rest and can changes.The paper knife of the trivial ledger-plate of useful locking cross bar, its weak point are the apparatus structure complexity of locking blade, and tool rest processing is inconvenient.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of locking device structure simply, conveniently to open and comfortable paper knife.

This use is novel to be achieved through the following technical solutions.

The utility model is a kind of paper knife, comprises blade, tool rest and handle of a knife, and tool rest on handle of a knife, is characterized in that tool rest has through hole with the position that the blade recess matches, and is equipped with the pin that matches in the through hole by the movable riveted of rivet.

The above number of openings is at least four, and wherein the position of two through holes cooperates with two recess of blade, and two other through hole is arranged at the top edge near tool rest.

The quantity of above-mentioned pin cooperates with the quantity of through hole, the two ends that are located in two pins of tool rest top edge through hole are separately fixed on two contiguous blocks, the length that is located in two pins of the through hole that cooperates with the blade recess is half of other two pins, and their end is fixed on the contiguous block.

Above-mentioned paper knife can also have following further improvement: be provided with a spring between contiguous block that only is connected with two pins and tool rest.

The beneficial effects of the utility model are: (1) the utility model adopts the pin locking, only need offer through hole on the tool rest and cooperate pin, and technology is simple, easy to process.(2) with two pins lockings blade, can guarantee that blade is lockable fully, and other two pins play the role of positioning, and guarantee the stability of whole locking device, can not occur rocking, out of position.(3) pin is connected on the contiguous block, and the contiguous block area is big, and the user is according to comfortable.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the utility model exploded exploded perspective view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Shown in Figure 2 as Figure 11, the utility model is a kind of paper knife, comprises blade 1, tool rest 2 and handle of a knife 3, and tool rest 2 passes through the movable riveted of rivet on handle of a knife 3, it is characterized in that tool rest 2 has through hole with the position that blade 1 recess matches, and is equipped with the pin that matches in the through hole.

As shown in Figure 2, tool rest 2 is provided with four through holes, and wherein two through holes 51 are arranged at the position of matching with blade 1 recess, is used to install the locking pin 61 of locking blade; All the other two through holes 52 are arranged at the top edge near tool rest 2, are used to install and fix the pin 62 of contiguous block position.

Pin and contiguous block have following annexation.The two ends that are located in two pins 62 of tool rest 2 top edge through holes are separately fixed on two

contiguous blocks

41,42, the length that is located in two pins 61 of the through hole 51 that cooperates with blade 1 recess is half of other two pins 62, their end is fixed on the contiguous block 42, simultaneously is provided with a spring 7 between with the contiguous block 41 of pin 62 and tool rest 2 only being connected with two.

During use, when firmly pressing lower connecting block 41, the recess that pin 61 breaks away from the blade 1, blade 1 can take out; When hand left contiguous block 41, under the elastic acting force of spring, pin 61 homings were blocked blade 1, and this moment, blade 1 can not take out.

Claims
