Description

A kind of unpacking cutter

Technical field

The utility model is related to a kind of unpacking cutters.

Background technology

At present, ordinary packing is being unpacked mostly using common cutter, use at low cost is also convenient for.It is but common Cutter in actual use, since packaging bag or band are generally tougher, is not easy to cut off.Common razor blade for carving tool compared with Thin, blade can distort and by lateral forces, therefore easily snap off during cutting.If its fragment enters in reactor, to production Quality and follow-up equipment adversely affect, in some instances it may even be possible to lead to equipment damage.In order to overcome existing cutter is easily broken to show Shape, the utility model provide a kind of new unpacking cutter.To be suitble to solve packet function in production.

Utility model content

The utility model provides a kind of unpacking cutter for being avoided that blade and fractureing.

To achieve these goals, the technical solution that the utility model is taken is：

The unpacking cutter including handle of a knife and blade, further includes the anti-stent that fractures, anti-stent one end installation that fractures On the handle of a knife, the other end is equipped with cutter groove, and the cutter groove clamps the bared end of the blade, the blade dew of the bared end Go out.

The elastic edge bearing for being clipped in the blade both sides is equipped on the inside of the cutter groove.

The anti-stent that fractures exposes the interlude of the blade for C fonts.

The cross section of anti-fracture stent and the blade connected end is isosceles trapezoid, and close to blade side, thickness is less than Opposite side.

The anti-stent that fractures is equipped with mounting groove with handle of a knife connected end, and clamping protrusion is equipped on the inside of the mounting groove, described Handle of a knife is inserted into the mounting groove and is equipped with and the matched clamping groove of the clamping protrusion.

The blade is slidably matched with the handle of a knife, and equipped with location structure；The handle of a knife side is equipped with blade in the same direction Sliding slot and bracket chute, the blade sliding slot are slidably matched with the location structure, the bracket chute and the anti-branch that fractures Slide bumping on frame matches, and the slide bumping is located at the anti-stent that fractures and installs in the mounting groove of the handle of a knife.

The location structure is connected with the anti-stent clamping that fractures.

Using above-mentioned technical proposal, shank portion secures the rear portion of blade, and if blade forepart expose part by Strength to side surface direction easily snaps off.The external part of blade forepart is secured by the anti-stent that fractures, can effectively prevent in this way Blade distortion during cutting and by lateral force, the defects of avoiding blade frangibility well.Blade exposed portion has been had The interlude exposed entirely, therefore can be cut with interlude, to avoid obstruction caused by the anti-stent that fractures.

It is anti-to fracture stent and the cross section of the blade connected end provide preferable support for blade external part, prevent side Blade is damaged to power, can also reduce and be interfered caused by when this is in cutting.The anti-stent that fractures is installed using detachable, such as Fruit blade is blunt, can remove the anti-stent more allowing blade replacement that fractures.The blade of cutter can be slided along the sliding slot of handle of a knife, can be adjusted in this way The length that blade exposes.Cutter structure can also be used in the utility model, and increases the anti-stent that fractures.In order to length can be changed Blade match, therefore the anti-stent that fractures is also using slidable mounting structure, and anti-can will be fractureed by clamping structure Stent is fixed together with the location structure on blade, slides together, more convenient to use.

Specific embodiment

Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present invention further detailed Explanation, with help those skilled in the art to the present utility model design, technical solution have it is more complete, accurate and deeply Understanding.

As shown in Figs. 1-2, the utility model provides a kind of unpacking cutter, includes two embodiments.First embodiment：Knife Handle 1 is removably to be fixedly connected with blade 2, and the exposed division that blade 2 is exposed on the external is fixed.The anti-stent 4 that fractures of C fonts One end is removably mounted on handle of a knife 1, and bared end of the other end then with blade 2 is connected.

Anti- 4 one end of stent that fractures have with the matched mounting groove in 1 side of handle of a knife, 1 grafting of handle of a knife is on this mounting groove.Peace At least one clamping protrusion 5 is equipped on the inside of tankage, if Fig. 1 is strip.1 side of handle of a knife is then equipped with corresponding clamping groove.

2 back side of blade can be inserted into cutter groove, the blade 3 of bared end exposes outside by anti-4 other end of stent that fractures with cutter groove Face.Cutter groove is supported blade 2 from side, distorts and fractures when in use to prevent it.In order to facilitate the insertion of blade 2 simultaneously, Both sides are equipped with elastic edge bearing inside cutter groove, and blade 2 is inserted into from the gap between elastic edge bearing, easy for installation and can obtain well Support.The cross section of anti-fracture stent 4 and 2 connected end of blade is isosceles trapezoid, is less than close to 3 side thickness of blade another Side.The obstruction for being in the anti-generation of stent 4 that fractures in cutting process can be reduced in this way.

The anti-stent 4 that fractures is C font, and intermediate portion does not block the part of the exposing of blade 2, therefore blade 2 fractures anti- Stent 4 and 2 connecting pin of blade are completely exposed to the interlude between the handle of a knife 1.It can be cut in this way with the blade 2 of interlude It cuts, without being hindered by the anti-stent 4 that fractures.

If the connection structure of blade 2 and handle of a knife 1 uses the sliding connection structure used in common cutter, this this practicality is new The structure of type is also required to improve, such as second embodiment.Compared to first embodiment, 1 side of handle of a knife is equipped with 8 He of blade sliding slot in the same direction Bracket chute 6.Blade 2 is equipped with location structure 7, for fixing blade 2 in suitable position.Blade sliding slot 8 and location structure 7 It is slidably matched.Clamping protrusion 5 in first embodiment mounting groove then replaces with the slide bumping being slidably matched with bracket chute 6. Blade 2 can be slided with adjusting position in this way, and the anti-stent 4 that fractures can also slide to coordinate the position of blade 2.During of course for adjusting More convenient, location structure 7 is connected with the anti-stent 4 that fractures by matched movable clamping structure clamping, and that loads onto anti-fractures Stent 4 just can together be slided with location structure 7.Pay attention to if this embodiment is by the whole income handle of a knifes 1 of blade 2, need to allow anti-folding Disconnected stent 4 is detached from location structure 7, and otherwise blade 2 cannot all take in handle of a knife 1.

The external part that the anti-stent 4 that fractures secures 2 forepart of blade can be transferred through using above-mentioned unpacking cutter, so as to effectively Prevent during cutting that blade 2 distorts and by lateral force, the defects of avoiding 2 frangibility of blade.The utility model has using peace Entirely, the advantages of 2 long lifespan of blade, and 2 fragment of blade is not likely to produce, equipment or product is avoided to be affected.

The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that the utility model methodology and technical solution carry out Into or it is not improved by the utility model design and technical solution directly apply to other occasions, the utility model protect Within the scope of shield.
