Abstract

A multi-edge knife belongs to a manual tool, which overcomes the defect of the single function in the prior art, the multi-edge knife tool of the utility model is provided with a knife handle, wherein one end of the knife handle is connected with at least one knife carrier through a pintle, namely the knife carrier is capable of gathering to the knife handle and a replaceable blade is installed on the knife carrier. The knife tool is characterized in that the other end of the knife handle is connected with a tool piece through a pintle, namely the knife carrier is capable of gathering to the knife handle, thereby the functions of the knife tool are developed, when in use, proper tool pieces can be selected to be used according to the requirements, and the other tool pieces can be gathered in the knife handle through the pintle, then more than two using requirements can be realized with one knife.

Description

The bull cutter

Technical field

The utility model belongs to hand-operated tools, a kind of specifically bull cutter.

Background technology

Existing hand knife, its common version are that the end at handle of a knife is provided with a blade, and function singleness is difficult to satisfy one cutter realized multiple user demand.

The utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that overcomes the function singleness of prior art existence, and a kind of bull cutter is provided.For this reason, the utility model adopts following technical proposals:

The bull cutter has a handle of a knife, and an end of handle of a knife has at least one knife rest that can draw in to handle of a knife through pivotally connected, and removable blade is installed on the knife rest, and the other end that it is characterized in that described handle of a knife has a tool piece that can draw in to handle of a knife through pivotally connected.This scheme is provided with plural tool piece by the two ends at handle of a knife, has therefore widened the function of cutter, can realize two or more user demands to cutter with one during use.

As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:

Being coaxially connected with described knife rest can be to the tool piece of handle of a knife gathering.

Described tool piece is blade, saw, cut, file, screwdriver or its any combination.

Described handle of a knife is provided with the keeper that cooperates with described pivot part.Be used for avoiding operate miss to hurt sb.'s feelings the blade location.

Described keeper is a latch plate, and described pivot part is provided with the location division that cooperates with the latch plate end face.This relatively simple for structure, can effectively avoid the cutter volume to become big.

The beneficial effects of the utility model are: being provided with by the two ends at handle of a knife can be to the tool piece of handle of a knife gathering, therefore widened the function of cutter, can select proper implements spare as required for use during use, obsoletely then can realize two or more user demands to cutter with one thus by pivoting gathering in handle of a knife.

The specific embodiment

The technical solution of the utility model is described further with embodiment below in conjunction with accompanying drawing.

Embodiment one

Shown in Fig. 1,2,3,4, this bull cutter directly connects a blade 22 in the lower end of handle of a knife 1 by pivot 42, the afterbody of this blade 22 is connected with pivot 42 as pivot part 32 and can rotates around pivot 42, thus can folding storage handle of a knife 1 in (referring to Fig. 5) or in the handle of a knife 1 expansion for use; Upper end at handle of a knife 1 connects a knife rest 5 by pivot 41, these knife rest 5 afterbodys are connected with pivot 41 as pivot part 31 and can rotate around pivot 41, blade 21 is installed on the knife rest 5, thereby can be with knife rest 5 and blade 21 folding storage together in handle of a knife 1 (referring to Fig. 5) or launch for use in handle of a knife 1.

Further, shown in Fig. 2,4, for blade and knife rest location, in handle of a knife 1, be provided with a latch plate as keeper 6, at the afterbody of lower end blade 22 location division 72 (locating surface) being set cooperates with the lower surface of latch plate, at the afterbody of knife rest 5 location division 71 (locating surface) being set cooperates with the upper surface of latch plate, thereby when launching blade, conflict on the location division of lower end blade in the lower surface of latch plate, conflicting on the locating surface of knife rest in the upper surface of latch plate, avoids operate miss to hurt sb.'s feelings.

Embodiment two

Shown in Fig. 6,7, the difference of this bull cutter and embodiment one is that its handle of a knife 1 is provided with three

blades

21,22,23, it is to have increased a blade 23 on the structure of embodiment one again, the knife rest 1 of this blade 23 and embodiment one is set up in parallel by its pivot part 33 and is connected on the same pivot 41, all the other structures repeat no more with embodiment one.

Need to prove, according to inventive concept of the present utility model, blade among above-mentioned two embodiment can with saw, cut, file, screwdriver or its any combination replacement, and, also can on the pivot of the same end of handle of a knife, connect two or more knife rest, and the blade that can change is installed on each knife rest, can also on the pivot of the handle of a knife other end, connect knife rest, and the blade that can change is installed on knife rest, repeat no more and so on.
