Abstract

The utility model relates to a pair of self-opening top cutting vice which comprises a left vice body, a right vice body and a vice shaft. The left vice body and the right vice body can be connected by the vice shaft and can move around the vice shaft. Each vice body is composed of vice handles, a vice shaft hole, a concave arc-shaped gap and a vice head. The concave arc-shaped gap is positioned at the top part of the vice head and is extended to the end edge position of the vice head. Each vice handle is provided with a mounting hole for a spring. One end of each spring is clamped in the mounting hole, and the other end of each spring is extended between two vice handles along the vice handle. The self-opening top cutting vice has the advantages of simple structure, convenient operation and wide application, can be used in some specific fields because the vice head position is provided with vice holes, and has the performances of self opening, etc., because springs are additionally arranged on the vice handles.

Description

The self-opening end cutter nippers

The utility model relates to instrument class field in the manufacturing enterprises such as medical treatment, factories and miness, belongs to a kind of end cutter nippers, especially is a kind of self-opening end cutter nippers.

At present, more in the various fields with the instrument pincers, pincers, cutting nipper etc. as daily, its structure is all unified mutually with its merit or performance, by its function of its structures shape.Continuous development along with technology, instrument in each production technical field is more and more perfect, and the pincers of many different structures have been released: be 90219692 medicine bottle Kaifeng pincers as the disclosed application number of Patent Office, this pincers comprise the upper and lower caliper that links with the pincers axle, the jaw of lower clamp is made up of two kinds of circular arcs of different-diameter, the jaw of upper clamp has an elongated slot, and cutting knife is housed in the groove; The multi-functional holding forceps of application number 93233491 and for example, its primary structure are to have finger ring on the pincers handle.No matter the structure of these pincers how, all substantial connection is arranged with its purposes.These pincers all exist it to use limitation, and its structure particularity, make its processing and fabricating difficult, and main in use armrest power is opened or merged its pincers handle, and its use is very inconvenient.Existing pincers generally have sheared edge and or the screw thread at binding clip place, but be suitable for band cap head shaft; And these pincers are required great effort in use because its hand vice (or pincers handle) are shorter.

The purpose of this utility model is to provide a kind of easy to use and have an end cutter nippers of top otch at above-mentioned situation; Its another purpose provides and a kind ofly adds spring at pincers handle place, has from the self-opening end cutter nippers of opening performance.

The purpose of this utility model realizes in the following manner: self-opening end cutter nippers of the present utility model includes left and right caliper, the pincers axle; Left and right caliper links to each other with the pincers axle and can be movable around the pincers axle.Caliper is made up of pincers handle, pincers axis hole, arcs of recesses breach and binding clip; The arcs of recesses breach is in the binding clip top and is extended down to the place, end limit of binding clip; The installing hole that has spring on the above-mentioned pincers handle, spring one end is stuck in the installing hole, and the other end extends between the two pincers handles along the pincers handle.

Self-opening end cutter nippers of the present utility model has simple in structure, easy to use and characteristics such as purposes is wider; Because the binding clip place has the pincers hole, can be used in some special dimensions; And the handle place is equipped with spring at pincers, has performance such as self to open; Extending in addition, it clamps handle, uses laborsaving.

Below in conjunction with accompanying drawing structure of the present utility model and technology contents thereof are further described:

Fig. 1 is a main TV structure schematic diagram of the present utility model (cut-away section);

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the top view of Fig. 1;

Fig. 4 is the A-A cutaway view of Fig. 1.

Referring to Fig. 1, Fig. 2, Fig. 3, end cutter nippers of the present utility model includes left and right caliper 1, pincers axle 2; Left and right caliper links to each other with the pincers axle and can be movable around the pincers axle.Caliper is made up of pincers handle 11, pincers axis hole 12, arcs of recesses breach 13 and binding clip 14; The arcs of recesses breach is in the binding clip top and is extended down to the place, end limit of binding clip, and the through hole of forming when the two halves arcs of recesses breach at this binding clip place, left and right sides closes up is the pincers hole; The installing hole 15 that has spring 3 on the above-mentioned pincers handle 11, spring 3 one ends are stuck in the installing hole 15, and the other end extends between the two pincers handles along the pincers handle.

Referring to Fig. 1, above-mentioned binding clip end face is the waist drum shape, and the surface of the horizontal line L of bottom is an arc surface from end face to breach.

Above-mentioned pincers handle place is with sheath 4, and the major part of spring 3 is encased by sheath.

Above-mentioned arcs of recesses breach is half cucurbit shape; Or the bottom is toroidal, and the top is triangular shape (referring to Fig. 1); Also can adopt other analogous shape as requested.

Referring to Fig. 4, on caliper 1, have pincers axis hole 12, being used for by pincers axle 2 two calipers 1 being connected together forms whole pliers, and its syndeton is consistent with the syndeton that has general pliers now, does not take off bright in detail at this.

The bottom of above-mentioned said pincers handle is circular-arc or arc shaped, its top has one section straightway (referring to Fig. 1), for laborsaving when the utility model uses, from global shape, the pincers handle is extended, the length of pincers handle is determined according to actual operating position, generally can select more than 2/3rds of whole pliers for use, the length that promptly clamps handle is more than 2/3rds of whole pliers length.Each spring stretches in its straightway and its end is touched mutually and produces elastic force, makes the pincers handle be in open configuration.

On above-mentioned pincers handle medial surface, have an evagination bar, sheath 4 is enclosed within on the pincers handle (referring to Fig. 1) securely.

Referring to Fig. 1, above-mentioned said spring is for having certain flexible spring leaf, the other end of a spring leaf therein has opening and is used to make the other end of another spring leaf to snap in its opening and since the effect of spring force under under normal circumstances, binding clip is in open configuration; Also can adopt the end of the other end of two springs to touch mutually to satisfy above-mentioned performance.
