Abstract

The invention provides a multi-functional knife which can not only be used as a straight knife, but also become a structure of a sickle as required. The multi-functional knife comprises a knife body, a first knife handle and a second knife handle, wherein the knife body is movably connected with the first knife handle through a first pin shaft and movably connected with the second knife handle through a second pin shaft; the first knife handle and the second knife handle are both in groove shapes; the first pin shaft and the second pin shaft are not positioned on a same horizontal line; when the first knife handle and the second knife handle respectively rotate around the first pin shaft and the second pin shaft and are closed in folding way, the knife is contained in a groove formed by the two knife handles; and the first knife handle and the second knife handle can be connected into an integer through a joggling structure.

Description

Utility knife

Technical field

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

Background technology

Cutter on the market divides two kinds: a kind of straight knife, straight knife is used for daily life, a kind of in addition be L shaped shape reaping hook can as the agricultural, wilderness lore, the 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 object of the invention provides a kind of utility knife, can not only use as straight knife, and can become the structure of reaping hook as required.

To achieve these goals, the present invention adopts following technical scheme:

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

Further, mortise structure is that first handle of a knife inboard projection or groove are 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 first bearing pin and the second bearing pin axial connecting line and the horizontal line.

Beneficial effect of the present invention:

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