Abstract

A foldable knife comprises a blade, a first rotary knife handle, a second rotary knife handle and a locking device. The tail end of the blade is provided with a front fixing column and a rear fixing column. The first rotary knife handle and the second rotary knife handle respectively comprise a first knife handle plate and a second knife handle plate. The front end of each first knife handle plate and the front end of each second knife handle plate are located on the two sides of the tail end of the blade respectively, and the first knife handle plate and the second knife handle plate are hinged through a hinge pin. Each first knife handle plate and the corresponding second knife handle plate are fixed in parallel through limiting pins located at the rear end of the first knife handle plate and the rear end of the second knife handle plate. According to the foldable knife, the tail end of the blade is provided with the front fixing column and the rear fixing column, the first rotary knife handle and the second rotary knife handle are symmetrically arranged on the two sides of the front fixing column and the rear fixing column, the first rotary knife handle and the second rotary knife handle are locked through the locking device when folded or unfolded, forces borne by the blade in all directions are balanced, the blade is stable, and therefore the foldable knife is safe in use.

Description

A kind of folding cutter

Technical field

The present invention relates to a kind of cutter, especially relate to and a kind ofly blade can be folded to the folding cutter in handle of a knife.

Background technology

Existing folding cutter major part is all made up of blade and the handle of a knife with certain cavity volume, blade is movably connected on handle of a knife by hinge, blade can be amounted in the cavity volume of handle of a knife with hand-power, also blade outwards can be launched from handle of a knife, on some folding cutter, switching device is installed, amounts to and launch blade by toggle switch device.Existing folding cutter is mostly amount to and launch blade or amount to and launch blade with hand toggle switch device with hand-power, easily hurts hand in the time amounting to and launch blade.In addition, because blade is mainly supported by elastic switch device, the strength that blade can bear in all directions is not identical, and blade is stressed easily to turn back when excessive.

The existing folding cutter Chinese utility model patent that for example patent No. is ZL200620060248.8, this patent discloses a kind of jackknife, it is made up of blade and handle of a knife, blade and the knife back of the link of blade and handle of a knife are respectively equipped with recess, two stators are fastened on respectively in two recesses, and two handle of a knifes are connected on two stators by connector.Although this jackknife has solved blade because of stressed excessive problem of easily turning back,, this jackknife is because of syndeton reason, after Reusability a period of time because the wearing and tearing of connector can cause the loosening of blade and connector.

Summary of the invention

In order to solve in prior art, folding cutter blade is stressed easily to turn back and the unsteady problem of blade, the invention provides another folding cutter.

The technical scheme that technical solution problem of the present invention adopts is: a kind of folding cutter comprises blade, the first rotation handle of a knife, the second rotation handle of a knife and locking device.The tail end of described blade is provided with front fixed leg and rear fixed leg, the blade end of described blade is front end, one end that described blade is connected with handle of a knife is tail end, and described front fixed leg is convenient to clamp described blade while amounting to for described the first rotation handle of a knife and described the second rotation handle of a knife; When rotating handle of a knife expansion for described the first rotation handle of a knife and described second, described rear fixed leg is convenient to clamp described blade.Described the first rotation handle of a knife and described the second rotation handle of a knife all comprise the first handle of a knife plate and the second handle of a knife plate, the shape of described the first handle of a knife plate is identical with the shape of described the second handle of a knife plate, and the front end of described the first handle of a knife plate and described the second handle of a knife plate lays respectively at the side on described blade tail end two sides it is hinged with bearing pin; The front end both sides of described the first handle of a knife plate and described the second handle of a knife plate are provided with recess, and described recess is for front fixed leg and described rear fixed leg described in interlock; The rear end of described the first handle of a knife plate and described the second handle of a knife plate is parallel fixing by the two with limiting pin, and will between described the first handle of a knife plate and described the second handle of a knife plate, limit certain interval, while folding for holding described blade; There is certain distance the installation site of described restriction pin from described the first handle of a knife plate with the end of the second handle of a knife plate, makes to form nick shaped in end between described the first handle of a knife plate and described the second handle of a knife plate, for locking device is installed.Described the first rotation handle of a knife and described the second rotation handle of a knife are arranged on the both sides of described front fixed leg and described rear fixed leg line, and described the first rotation handle of a knife and described the second rotation handle of a knife are separately positioned on the monosymmetric position of mid point of described front fixed leg and described rear fixed leg line with the hinged bearing pin of described blade tail end respectively.Described locking device comprises snap close, described snap close is T font, the bottom of described snap close is movably connected in the tail end breach of described the first rotation handle of a knife or described the second rotation handle of a knife, and the top of described snap close buckles into when amounting to or launching in the breach of tail end that described the second rotation handle of a knife or described first rotates handle of a knife and hooked at described the first rotation handle of a knife and described the second rotation handle of a knife.

The invention has the beneficial effects as follows: a kind of folding cutter of the present invention, because blade tail end is provided with front fixed leg and rear fixed leg, the first rotation handle of a knife and the second rotation handle of a knife are symmetricly set on the both sides, center of front fixed leg and rear fixed leg, the first rotation handle of a knife and the second rotation handle of a knife are locked by locking device in the time amounting to or launch, what blade all directions were born balances in power and firmly, uses safety.
