Abstract

The utility model provides an injection uncork is cut, it includes two articulated handle of a knifes, the front end of handle of a knife is pressing part, and every pressing part passes through the radial spring coupling semicircular sword of a plurality of, and the inboard of sword is the cutting edge, and two cutting edges set up relatively, and when pressing part compressed tightly, two cutting edges constituted a whole circle. The utility model discloses compare with the uncork mode, its beneficial effect lies in: all design two cutting edges into semi -circular, only point contact between the cutting edge of having avoided prior art and the glass bottle, cause pressure too senior general's bottleneck break, garrulous glass entering liquid medicine, so, the utility model discloses it is safer. Two semicircular cutting edges all do work simultaneously, have also saved the time and the efficiency of operation.

Description

A kind of injection uncork is cut

Technical field

The utility model relates to medical field, is specifically related to a kind of for surgery injection bottle opening device.

Background technology

When medical worker usually uses and injects liquid medicine, the thin sand sheet of the usual use one piece band edge of a knife, the neck location of liquid medicine glass bottle draw several under, then with the upper end that hand directly contacts line, bottleneck is broken into two with one's hands, or some medical workers knock until bottleneck break by hard object at bottleneck position when medication, all there is certain familiar lacunas through reality textual criticism in above method.For this reason, name is called that injection uncork is cut, and application number is 201520254584.5 disclose a kind of uncork and cut, and through using, finds that bottleneck still can break by it, reason be the blade of side for being straight line, blade and glass bottle point cantact, too large to the pressure of bottle.

Utility model content

For the technical deficiency of above-mentioned existence, the purpose of this utility model be to provide one not easily bottleneck is broken injection uncork cut.

The technical solution adopted in the utility model is specially:

A kind of injection uncork is cut, and it comprises two hinged handle of a knifes, and the front end of handle of a knife is press keeping section, each press keeping section connects semi-round cutter by several radial springs, and the inner side of cutter is blade, and two blades are oppositely arranged, when press keeping section compresses, two blades form a full circle.

Described blade comprises several sawtooth, and the tip of the sawtooth on each blade is in same space circle.

Each sawtooth is to nearer sloped-end.

The grip part of described handle of a knife bends to the inside.

The utility model is compared with uncork mode, and its beneficial effect is: two blades are all designed to semicircle, avoids between the blade of prior art and glass bottle and only has a point cantact, cause pressure too senior general's bottleneck break, cullet enter liquid, so the utility model is safer.Two semi-round blades do work all simultaneously, also save time and the efficiency of operation.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the enlarged diagram of blade.

Detailed description of the invention

As shown in Figure 1, Figure 2, the utility model comprises two hinged handle of a knifes 1, hinge-point is the mark 11 in Fig. 1, the front end of handle of a knife 1 is press keeping section 2, each press keeping section 2 connects semi-round cutter 3 by several radial springs 4, and the inner side of cutter 3 is blade 31, and two blades 31 are oppositely arranged, when press keeping section 2 compresses, two blades 31 form a full circle.

Blade 31 comprises several sawtooth 32, and the tip of the sawtooth 32 on each blade is in same space circle, and all sawtooth 32 are all to nearer sloped-end.Blade 31 is designed to zig-zag, is the strength in order to reduce to draw lower vestige when uncork.If sawtooth all cw tilts, certainly also more convenient, the direct clickwise of the right hand.But, China probably by about 5% " left handed ", they are by very inconvenient use.So be designed to by sawtooth tilt to both sides, which hand don't work, all easy to use.And, when rotating back and forth, there is the blade of side in work.

The grip part of handle of a knife can bend to the inside, is convenient to the gripping of hand.

Its principle of work is:

During use, grasp the grip part of handle, the bottleneck of medicine bottle is placed on fastening between two blades after, rotate back and forth handle, vestige that can be darker under the neck of glass bottle is drawn, exit glass bottle, handle is returned to initial position.Then easily medicine bottle can be broken disconnected opening with hand.

During use, carry out back rotation scissors, vestige that can be darker under the neck of glass bottle is drawn, then can easily medicine bottle be opened with hand, easy to operate, save time, avoid glass fragment when knocking and enter problem in liquid, the injury of opponent when the direct hand of operating personal is broken can be reduced simultaneously.
