Description

Hand cut-off knife

The utility model relates to a kind of manual tool cutter, particularly a kind ofly is used to cut out the Hand cut-off knife that cuts soft, thin material.

A kind of Hand cut-off knife commonly used is by handle of a knife, blade, pushing block, and locking mechanism is formed.During use, it is outer to suitable length to utilize pushing block that sharp thin blade is released handle of a knife, and locking makes back, blade location cut out material and cuts, with after blade can be regained in the handle of a knife again, safe in utilization, conveniently.And be carved with many shallow slots parallel to each other along the blade total length is equidistant on blade plane, its effect be the land when blade point of a knife place can utilize this shallow slot that stubbed this section blade is fractureed when not sharp need not, therefore blade thickness is thinner, when sanction is cut multi-layered paper or thicker material, blade is flexible, sometimes even fracture, and crooked blade makes institute's material that cuts of cutting out irregular, and the sanction line is not straight.

The purpose of this utility model provides that a kind of blade is not flexible to fracture, and cuts out and cuts the neat Hand cut-off knife of material.

This cutter is mainly by handle of a knife, blade, and pushing block, locking mechanism is formed.1 to 2 land is arranged on its blade, 1 to 2 gathering sill is arranged on the handle of a knife of handle of a knife and blade place Plane intersects, be placed in cutter holder on the blade and place the gathering sill of handle of a knife, shifting block is arranged on the cutter holder, shifting block is arranged in the groove that communicates with gathering sill and stretches out outside the handle of a knife, promote shifting block, cutter holder will move on blade along gathering sill.If cutter holder is to be placed on the land of blade, then be equipped with in this cutter holder with cutter holder fixedly connected protect the sword sheet.When reality is used, can stretch out the length of handle of a knife and the material that cuts of cutting out determines that cutter holder is positioned at the length on the blade according to blade, thereby increase the intensity and the rigidity of blade.When blade adopts twolip, after the side edge band rust, but utilize cutter holder still safe ready ground use opposite side land cut out and cut material.

The utility model has the advantages that: blade is not flexible, fracture, and use safety and reliability, and keep the original advantage of this cut-off knife, and it is neat, accurately to cut the sanction line of multi-layered paper.The life-span of cutter also obtains prolonging.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a side view of the present utility model;

Fig. 3 is a cutaway view of the present utility model.

By Fig. 1; Fig. 2; Fig. 3 as can be known; according to the land on the blade 2 is single-blade; or twolip; then on the handle of a knife 4 at handle of a knife 4 and Plane intersects place, blade 2 place, make one to two gathering sill 9; promptly when blade 2 is single-blade; then on the handle of a knife 4 of the knife back place of blade 2 side, make a gathering sill 9; when blade 2 is parallel twolip; then on handle of a knife 4, make two gathering sills 9; cutter holder 3 correspondingly is placed in the groove 9 and is placed on the blade 2; for then have in the cutter holder 3 on the land 1 of blade 2 protection land 1 injury-free protect sword sheet 10, protect sword sheet 10 usefulness soft metals or nonmetallic materials and make.Each cutter holder 3 all has a shifting block 7, and shifting block 7 is arranged in the groove 8 that communicates with gathering sill 9, and stretches out in outside the handle of a knife 4.During use, cut the size and the thickness of material, promote pushing block 5 according to sanction, when blade 2 is stretched out suitable length from handle of a knife 4,, promote shifting block 7 again with blade 2 location, also along blade 2 and gathering sill 9 in move to Len req with shifting block 7 all-in-one-piece cutter holders 3 this moment, and can cut out and cut this moment.For blade 2 is the cut-off knife of twolip, when a side edge band rust, and turning handle of a knife 4, and regulate corresponding cutter holder 3 and be in position on the blade 2, then can utilize the sharp land of opposite side to cut out and cut material.Because cutter holder 3 strengthens the intensity and the rigidity effect of blades 2, even when therefore utilizing this cut-off knife to cut out to cut multi-layered paper or thicker material, blade 2 also is difficult for flexural deformation or fractures, and makes that to cut out the material that cuts neat, accurately.
