Description

Quick-opening and-closing outdoor knife

Technical Field

The utility model belongs to the cutter field especially relates to an outdoor sword that opens and shuts fast.

Background

The outdoor cutters are various in types, the structure of the outdoor cutters is roughly divided into two types, one type is a folding type opening and closing cutter, the other type is a sheath type opening and closing cutter, opening and closing of the two types of cutters are operated by two hands, and the two types of cutters cannot be operated by one hand, so that the use under special conditions is influenced. In addition, the existing cutter has slow opening and closing speed.

SUMMERY OF THE UTILITY MODEL

For solving the problem among the background art, the utility model provides a quick open-close outdoor knife, the utility model discloses possess the one hand characteristics of opening and shutting, opening and shutting fast.

The utility model provides a technical scheme is: the utility model provides an outdoor sword that opens and shuts fast, includes blade, handle, connection piece one and connection piece two, and the one end of connection piece one and connection piece two articulates respectively on the handle, and the other end of connection piece one and connection piece two articulates respectively on the blade to under the fixed circumstances of handle, connection piece one, connection piece two and the linkage of blade three make the blade stretch out or withdraw relative handle.

The technical scheme is that the thickness of the front end of a handle for hinging a first connecting sheet and a second connecting sheet is smaller than that of the rear end of the handle, a step is arranged between the thin part and the thick part of the handle, the second connecting sheet abuts against the step of the handle in the retracting state of a knife, the outline of the second connecting sheet at the abutting position is matched with the outline of the step, the second connecting sheet abuts against the first connecting sheet in the opening state of the knife, and the second connecting sheet at the abutting position is matched with the outline of the first connecting sheet.

The further technical scheme is that the blade is an arc-shaped plate, one end of the arc-shaped plate is pointed, and a cutting edge is machined on the inner side of the arc-shaped plate at the pointed end.

The further technical scheme is that the contour of one side of the connecting sheet far away from the connecting sheet II is provided with an arc-shaped groove for improving the comfort degree of fingers when the fingers are held tightly.

The further technical scheme is that a circular ring for connection is arranged at the rear end of the handle.

The utility model has the advantages that:

1. the utility model discloses, compact structure can open and shut fast by one hand.

2. The utility model discloses under the well sword state of withdrawing, the thin part of handle can hold partial tapping even piece to further reduce the volume of the sword under the state of withdrawing.

3. The blade in the utility model is provided with a tip shape which is easy to be inserted into the cut object.

4. The utility model discloses the comfort level is higher during the use, easily promotes the dynamics of having an effect.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail.

With reference to the attached drawings 1-6, the utility model discloses a blade 1, handle 3, connection piece one 4 and connection piece two 2, the one end of connection piece one 4 and connection piece two 2 articulates respectively on handle 3, and the other end of connection piece one 4 and connection piece two 2 articulates respectively on blade 1 to under the rigid condition of handle 3, connection piece one 4, connection piece two 2 and the linkage of 1 three of blade make blade 1 stretch out or withdraw relative handle 3. During the use, promote blade 1 through the thumb, can open or withdraw the sword, so, but this application one hand opens and shuts fast.

The thickness of the front end of the handle 3 for hinging the connecting piece I4 and the connecting piece II 2 is smaller than that of the rear end of the handle 3, a step 301 is arranged between the thin part and the thick part of the handle 3, the connecting piece II 2 abuts against the step 301 of the handle 3 in the retracting state of the knife, the outline of the connecting piece II 2 at the abutting position is matched with the outline of the step 301, and the connecting rod II 2 is partially accommodated in the handle, so that the volume of the knife in the retracting state is further reduced.

When the knife is in an open state, the connecting sheet II 2 abuts against the connecting sheet I4, and the abutting part of the connecting sheet II 2 is matched with the profile of the connecting sheet I1.

The blade 1 is an arc-shaped plate, so that the material is saved, one end of the arc-shaped plate is a sharp 102, the sharp 102 is easily inserted into an object to be cut, and a cutting edge 101 is machined on the inner side of the arc-shaped plate at one end of the sharp 102, as shown in fig. 2, when the knife is retracted, the cutting edge 101 is hidden, so that people are prevented from being injured.

Keep away from the profile of one 4 one side of connection piece two 2 and be provided with the arc recess 401 that promotes finger comfort level when holding tightly, during the use, the finger hold in arc recess 401 in, so the utility model discloses the comfort level is higher during the use, easily promotes the dynamics of having an effect.

The rear end of the handle 4 is provided with a ring 302 for connection, so that the outdoor carrying is convenient.
