Abstract
The utility model discloses a kind of from the cutter that fractures, it include: knife handle, blade, positioning device and knife tail-hood, the blade and the positioning device are set in knife handle, the blade is broken multisection type blade, the blade tail portion is connect with the positioning device, the positioning device and knife handle cooperation position, thus by blade positioning in a position, the knife tail-hood is embedded in knife handle tail portion, blade broken part is provided on the knife tail-hood, it is fractureed by blade broken part with blunt blade uppermost in use, removing knife tail-hood.The utility model overcomes the defect of existing cutter snap blade inconvenience, is quickly fractureed with blunt blade, to greatly improve service efficiency and safety.
Description
Technical field
The utility model belongs to hand cutting tool technical field, and in particular to a kind of from the cutter that fractures.
Background technique
The service life of cutter currently on the market depends primarily on the service life of blade, past in cutting operation
Cutting operation is carried out toward point of a knife is only used, so a situation often occur is exactly the exquisite cutter of production only because knife
Point would have to scrap with blunt, causes very big waste.It is broken more that current solution is that the blade of cutter is made into
Segmentation blade, point of a knife just fracture point of a knife after being worn out, and the point of a knife of back segment continues to use, and greatly prolong the service life of cutter, but
In existing scheme, fractureing for blade needs special fracturer, and buys the client of cutter often without special fracturer,
Or even if having what fracturer was also required to take time and effort to go temporarily to find, more troublesome, efficiency is not high enough, or without using special
Fracturer and by by hand fracture, cause safety problem.
Utility model content
The purpose of this utility model: providing a kind of cutter that fractures certainly, overcomes existing cutter snap blade inconvenience
Defect, realization is quickly fractureed with blunt blade, to greatly improve the purpose of service efficiency and safety.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of from the cutter that fractures, comprising: knife
Handle, blade, positioning device and knife tail-hood, the blade and the positioning device are set in knife handle, and the blade is broken
Multisection type blade, the blade tail portion connect with the positioning device, and the positioning device and knife handle cooperation position, thus will
For blade positioning in a position, the knife tail-hood is embedded in knife handle tail portion, is provided with blade broken part on the knife tail-hood, uses
When, it removes knife tail-hood and is fractureed by blade broken part with blunt blade uppermost.
In one embodiment, the positioning device includes sliding support and Location resilient piece, the sliding slot on the knife handle
Teeth portion is provided on side, the Location resilient piece is installed in sliding support, exposes the head of protrusion, when positioning, the head
It is stuck in a tooth socket of the teeth portion.
In one embodiment, the Location resilient piece is W-shaped, and the head is the lug boss among W, and the head is
It is arc-shaped.
In one embodiment, the blade broken part is a gap, and the thickness in the gap is slightly larger than blade thickness
Degree.
The utility model has the advantages that: by the setting blade fracturer in knife handle rear removable, significantly facilitate art designing
User, blade after being worn out can quick snap blade, greatly improve working efficiency, and extend cutter service life, lead to
W-shaped positioning device positioning blade is crossed, so that positioning is simpler reliable, in the usage scenario of light-duty art designing, more meets use
The use habit of person.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below in conjunction with attached drawing and reality
Applying example, the utility model is described in further detail, and the accompanying drawings in the following description is only section Example of the invention, for this
For the those of ordinary skill of field, without creative efforts, it is attached to can also be obtained according to these attached drawings other

Fig. 1 is the main view and its partial sectional view of the cutter of the utility model；
Fig. 2 is the positioning device structure schematic diagram of the cutter of the utility model；
Fig. 3 is the knife tail cover structure schematic diagram of the cutter of the utility model；
Fig. 4 is the structural schematic diagram of the Location resilient piece of the cutter of the utility model.
Specific embodiment
It is practical below in conjunction with this in order to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Technical solution in new embodiment carries out clear, complete description, it is clear that described embodiment is the portion of the utility model
Point embodiment, rather than whole embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not paying creation
Property labour under the premise of every other embodiment obtained, belong to the protection scope of the utility model.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
As shown in Figure 1 is a kind of from the cutter that fractures, comprising: knife handle 1, blade 2, positioning device 3 and knife tail-hood 4, it is described
Blade 2 and the positioning device 3 are set in knife handle 1, and sliding slot is provided on the knife handle 1, and the positioning device is set to cunning
In slot, can be slided up and down along sliding slot, the blade 2 be broken multisection type blade, 2 tail portion of blade with it is described fixed
Position device 3 connects, as shown in Figure 1, can be through cylinder pin connection.The positioning device 3 is positioned with the cooperation of knife handle 1, thus
Blade 2 is positioned at a position.The knife tail-hood 4 is nested in 1 tail portion of knife handle, is provided with blade on the knife tail-hood 4 and fractures
Portion 41 is fractureed by blade broken part 41 with blunt blade uppermost in use, removing knife tail-hood 4.As shown in figure 3, the knife
The structure of piece broken part 41 is preferably a gap, and the thickness in the gap is slightly larger than 2 thickness of blade.In use, seam will be used
Gap clamps blade, gently fractures with blunt blade.By the setting blade fracturer in knife handle rear removable, beauty is significantly facilitated
Work user, blade after being worn out can quick snap blade, greatly improve working efficiency, and extend cutter service life.
Specifically, as illustrated in fig. 1 and 2, the positioning device 3 includes sliding support 31 and Location resilient piece 32, the knife handle 1
On sliding slot side on be provided with teeth portion 11, the Location resilient piece 32 is installed in sliding support 31, expose protrusion head
321, when positioning, the head 321 is stuck in a tooth socket of the teeth portion 11.As shown in figure 4, the Location resilient piece 32 is preferably
To be W-shaped, the head 321 is the lug boss among W, and the head 321 is arc-shaped.Pass through W-shaped positioning device knife edge
Piece in the usage scenario of light-duty art designing, more meets the use habit of user so that positioning is simpler reliable.
