Abstract
The utility model relates to a medical field of cutting discloses a medical cutting with concave surface cutting edge, about by two cutting edge (1), about with two cutting edge (1) respectively two left and right sides of structure as an organic whole cut handle (2) and constitute that two cutting edge (1) articulate through round pin axle (3) about, round pin axle (3) is located between the head and afterbody of controlling two cutting edge (1), and fixes on the piece cutting edge of a left side, the internal surface middle part of controlling two cutting edge (1) is arc concave surface (11), and the internal surface edge is plane (12). Compared with the prior art, the utility model discloses friction about can reducing between two cutting edges can not influence the shearing effect simultaneously, promotes cutting edge life, when the user uses more nimbly and freely.
Description
Technical field
The utility model relates to hospital scissors field, particularly a kind of hospital scissors with concave surface cutting edge.
Background technology
Needs owing to shearing in prior art, two, left and right cutting edge 1 cutting edge when closed of hospital scissors generally can paste and tighter, frictional force between two cutting edges is comparatively large, and when hospital scissors is just brought into use because frictional force is comparatively large, user's use is cut handle 2 and opened and easy and flexible inadequate during closed cutting edge 1; After hospital scissors service time is of a specified duration, can the laminating between two panels cutting edge 1 be made gradually to fluff due to the long-term friction between two cutting edges again, finally can not meet shearing requirement, the hospital scissors life-span be shorter.
Utility model content
utility model object:for problems of the prior art, the utility model provides a kind of hospital scissors with concave surface cutting edge, can reduce the friction between the two panels cutting edge of left and right, simultaneously can not affect shear effect, promotes cutting edge service life, when user uses more nimbly and freely.
technical scheme:the utility model provides a kind of hospital scissors with concave surface cutting edge, cut handle by left and right two panels cutting edge, two, left and right being respectively integrative-structure with left and right two panels cutting edge to form, left and right two panels cutting edge passes through hinge, described bearing pin is between the head and afterbody of left and right two panels cutting edge, and be fixed on left cutting edge, be arc-shaped concave in the middle part of the inner surface of described left and right two panels cutting edge, inner surface edge is plane.
Further, the junction of cutting handle at the cutting edge of described left and right two panels cutting edge and two, left and right also offers the fixing finger mark groove of shape respectively.Offer finger mark groove to remove the unnecessary scissors material in junction, the friction of cutting when handle closes or opens two cutting edges between junction can be reduced by the one hand, enable user be more prone to closed or open cutting edge, promote the service life of cutting edge; On the other hand finger mark groove offer the performance not affecting hospital scissors completely, and with need in prior art compared with manual polishing, because the shape of finger mark groove is fixed, to be completed by machining, efficiency is higher, and be made into often the profile of hospital scissors can be kept completely the same.
Preferably, described finger mark groove is by the shaping or numerical control machine-shaping of open die extrusion.Open die extrusion technology and Computerized Numerical Control processing technology are all existing mature technologies, and the finger mark groove shapes formed out is fixed, good looking appearance, and can adopt mechanization production, production efficiency is higher.
beneficial effect:the inner surface of hospital scissors left and right two panels cutting edge is generally planar structure, but the cutting edge of planar structure makes the frictional force operationally between left and right two panels cutting edge larger, need to use larger power, the arc-shaped concave will being designed to concave in the middle part of the inner surface of left and right two panels cutting edge in the utility model, the marginal portion of inner surface is designed to plane, namely such design can reduce the frictional force between two cutting edges of left and right, does not affect the power of cutting out again, can also save scissors material to a certain extent.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
embodiment 1:
Present embodiments provide for a kind of hospital scissors with cutting edge line, as shown in Figure 2, left and right two panels cutting edge 1 and two, the left and right of this hospital scissors are cut handle 2 and are structure as a whole and (only depict left cutting edge of hospital scissors in figure and cut handle, right cutting edge is with to cut handle identical with left, therefore right omission), the two is by the hinged composition hospital scissors of bearing pin 3, bearing pin 3 is between the two head and afterbody, and be fixedly connected with left cutting edge, when being cut handle 2 by left and right two panels and opening with closed left and right two panels cutting edge 1, ensure that bearing pin 3 rotates together with left cutting edge, must not stripped thread, bearing pin 3 also can change screw into and use, in addition, arc-shaped concave 11 is all designed to by the middle part of the inner surface of left and right cutting edge 1 in present embodiment, inner surface edge is designed to plane 12, compared with plane cutting edge (as Fig. 1) of the prior art, the present embodiment frictional force that can reduce between left and right cutting edge 1 can not affect again simultaneously cuts out effect.
embodiment 2:
Present embodiment is the further improvement of embodiment 1, main improvements are, the junction of cutting 2 at the cutting edge of left and right two panels cutting edge 1 and two, left and right in present embodiment also offers finger mark groove 4 respectively, this finger mark groove 4 can by the shaping or numerical control machine-shaping of open die extrusion, as shown in Fig. 2,4 and 5, this guide groove 4 most between bottom surface and the inner surface of cutting edge 1, there is certain height difference H.Use that open die extrusion is shaping is convenient to mechanization, production efficiency compared with manual polishing is higher with needing in prior art, and finished appearance is consistent.
Above-mentioned embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
