Abstract

The utility model provides a multifunctional knife which can not only used as a straight knife, but also serve as a structure of a sickle. The technical scheme provided by the utility model is that the multifunctional knife comprises a knife body, a first knife handle and a second knife handle. The knife body is moveably connected with the first knife handle through a first pin roll, and the knife body is moveably connected with the second knife handle through a second pin roll. The first and second knife handles are groove-shaped. The first and second pin rolls are not in a same horizontal line. When the first and second knife handles rotate around the first and second pin rolls respectively to fold and close, the knife body is accommodated in the grooves of the two knife handles. The first and second knife handles are connected integrally through a joggle joint structure.

Description

Utility knife

Technical field

The utility model relates to a kind of utility knife, according to different situations, becomes at any time the structure of straight knife or reaping hook.

Background technology

Cutter on the market divides two kinds: a kind of straight knife, straight knife are used for daily life, and another is that the reaping hook of L shaped shape can be as agricultural, wilderness lore, defence etc.Two kinds of cutter effects are extensive, and each have their own advantage because profile is different, is difficult to the advantages with both.

Summary of the invention

The utility model purpose provides a kind of utility knife, can not only use as straight knife, and can become as required the structure of reaping hook.

To achieve these goals, the utility model is by the following technical solutions:

A kind of utility knife comprises cutter hub, the first handle of a knife and the second handle of a knife; Cutter hub is flexibly connected through the first bearing pin and the first handle of a knife, and cutter hub is through the second bearing pin and the flexible connection of the second handle of a knife, and the first handle of a knife and the second handle of a knife all are groove type; The first bearing pin and the second bearing pin be not at the same level line; When the first handle of a knife and the second handle of a knife respectively when the first bearing pin and the second bearing pin rotation doubling are closed, cutter hub is contained in the groove of two handle of a knifes; The first handle of a knife and the second handle of a knife can connect as one by mortise structure.

Further, mortise structure is projection or the groove that the first handle of a knife inboard is set, and the second handle of a knife inboard is provided with at least one groove that cooperates above-mentioned projection or groove fit or projection.

Further, become 30 ° of-60 ° of angles between the first bearing pin and the second bearing pin axial connecting line and the horizontal line.

The beneficial effects of the utility model:

Not only effectively in conjunction with reaping hook and straight knife, and be convenient for carrying after folding, use more extensive; Overall structure is simple, and is reasonable in design.
