Abstract

The utility model belongs to the hardware knife field, which aims to provide a novel knife which has the novel structure of a knife handle, and stable structure and manufacturing material conservation. The utility model comprises a knife blade and a knife handle, wherein one end of the knife blade is riveted on the knife handle through a rivet, the knife handle is composed of a handle seat and a pushing rod, one end of the pushing rod is movably connected with one end of the handle seat, the other end of the pushing rod is movably connected with the end part of the knife blade, a spring is connected between the handle seat and the pushing rod, one end of the spring is fixed on the handle seat, and the other end is fixed on the pushing rod. The utility model has the advantages that the pushing rod belongs to one part of the knife handle, and not only can be taken as a grip, but also can be taken as a locking mechanism, thus having the dual function, and saving the manufacturing material of the knife handle part.

Description

A kind of novel pocket knife

Technical field

The utility model belongs to five metals cutter field, relates in particular to a kind of novel pocket knife.

Background technology

At present, the pocket knife of Xiao Shouing all is to pass through the movable riveted of rivet on handle of a knife by blade on the market, the shell fragment roof pressure blade that utilization is installed in the handle of a knife back prevents that blade rotation is excessive, service time, the elasticity of long back shell fragment was degenerated, can not well play spacing effect, cause the conjugation between cutter hub and the handle of a knife to reduce, the phenomenon of rocking appears easily, also have utilize the safety plate roof pressure blade be arranged at the handle of a knife end prevent blade rotation pocket knife, but inconvenient operation and need more material.

Summary of the invention

The purpose of this utility model is in order to solve the above problems, and a kind of handle of a knife position novel structure is provided, structure is firm and saves a kind of novel pocket knife of manufactured materials.

The utility model is achieved through the following technical solutions.

The utility model is a kind of novel pocket knife, comprise blade and handle of a knife, blade one end by closing-up on handle of a knife, described handle of a knife is made up of handle seat and push rod, one end of described push rod and an end of handle seat flexibly connect, and the other end of push rod and blade end flexibly connect, and are connected with spring between described handle seat and the push rod, one end of spring is fixed on the handle seat, and the other end is fixed on the push rod.

Above-mentioned push rod is made up of first push rod and second push rod, one end of first push rod rivets together by rivet and blade end activity, the other end of first push rod rivets together by an end activity of the rivet and second push rod, and the other end of second push rod rivets together by an end activity of rivet and handle seat;

Above-mentioned first push rod is made up of the identical brace of two plate shapes size, is fixed together by pin between two braces;

Above-mentioned second push rod is made up of the identical brace of two plate shapes size, is fixed together by pin between two braces;

Above-mentioned spring is a bar-spring, and an end of spring is fixed on the pin on the handle seat, and the mid portion of spring is fixed on another pin of handle seat, and the other end of spring is fixed on the pin on second push rod.

Advantage of the present utility model is that push rod is the part of handle of a knife, be handle be again locking mechanism just, have double action, and saved the manufactured materials of shank portion, the novel structure practicality.

The specific embodiment

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

As shown in Figure 1, handle of a knife is made up of handle seat 1 and push rod, push rod is made up of first push rod 21 and second push rod 22, one end of first push rod 21 rivets together by rivet and blade end activity, the other end of first push rod 21 rivets together by an end activity of the rivet and second push rod 22, and the other end of second push rod 22 rivets together by an end activity of rivet and handle seat 1.First push rod 21 is made up of the identical brace of two plate shapes size, be fixed together by pin between two braces, second push rod 22 also is made up of the identical brace of two plate shapes size in the same manner, is fixed together by pin between two braces.

Be connected with bar-spring 3 between handle seat 1 and the push rod, an end of spring 3 is fixed on the pin 11 on the handle seat 1, and the mid portion of spring 3 is fixed on another pin 12 of handle seat 1, and the other end of spring 3 is fixed on the pin 23 on second push rod 22.

Operation principle of the present utility model is as follows, and as Fig. 2, Fig. 3 and shown in Figure 4, second push rod 22 is riveting on the handle seat 1 by the rivet activity, and second push rod 22 can be that the rotating shaft certain amplitude rotatablely moves with the rivet.Carry out the transition to from folded position the full open position process at blade, blade drives first push rod 21 and moves right, and first push rod, 21 promotions, second push rod 22 is done and rotated counterclockwise; When blade position and handle seat 1 are vertical, 21 beginnings of first push rod are to left movement, driving second push rod 22 does and clockwise rotates, when blade is opened fully, the angle that first push rod 21 and second push rod 22 form is greater than 180 °, if this moment, blade carried out the transition to folded position from full open position, can only drive first push rod 21 moves right, promptly first push rod 21 can promote second push rod 22 and continues to do and clockwise rotate, but under the obstruction of handle seat 1, second push rod 22 can't have been done and clockwise rotate, thereby blade can not reach the locking blade and prevent the purpose that blade turns back from open mode excessively to folded position.

The unique way that blade will be turned back is exactly manually to push down second push rod 22 it to be done rotate counterclockwise, angle between first push rod 21 and second push rod 22 is less than 180 °, first push rod 21 could promote second push rod 22 and do and rotate counterclockwise, and blade just can be amounted to.The effect of spring 3 is to press second push rod 22, makes it maintain the trend that clockwise rotates of doing, and helps blades open, helps first push rod 21 and second push rod 22 can form angle greater than 180 ° simultaneously.
