Description

A kind of general clamps of elasticity shell case

Technical field

The utility model belongs to clamp art, and in particular to a kind of general clamps of elasticity shell case.

Background technology

In the shell case that spot is found, microscopic analysis and comparison must be carried out to the marks on surface of shell case, be confirmed whether it is Public security department puts on record the bullet that gun are got, so that it is determined that the field of investigation of case.It is carried out in the marks on surface of shell case micro- When analysis and comparison, erroneous judgement is generated to ensure that cartridge case no longer generates new trace, shell bore can only be used as support Clamping.When the marks on surface of shell case carries out microscopic analysis and compares, the usual clay of shell case clamping mode fixes, rubber head or plastics Circle, which is fixed, and steel wire is brush fixes three kinds.Three of the above fixed form manifests respective drawback, glue during use It is exactly that shell case is fixed on the table by the viscosity of clay that mud, which is fixed, and the fixed form efficiency and reliability is low, at present very It is few to use；Rubber head or plastic ring are fixed, referring to FIG. 4, rubber head or plastic ring are processed into plurality of specifications by the size of shell bore, Shell case fixation is fixed by the extruding of shell bore and rubber head；The brush fixation of steel wire, referring to FIG. 5, wire brush presses shell case The size of endoporus is processed into plurality of specifications, and shell case is fixed to be fixed by the extruding generation elastic force of shell bore and wire brush. The range of shell bore substantially in 5~13mm of Ф, latter two fixing means when in use first distinguish the specification of shell case to select The rubber head or plastic ring of appropriate size, wire brush are fixed, and there are certain inconveniences for both fixed forms, and then one Determine to affect working efficiency in degree, furthermore, shell case port wall is relatively thin, and as the edge of a knife, installation is accidentally easy to cut rubber head Or plastic ring.

Invention content

The goal of the invention of the utility model is that shell case fixture for the above-mentioned prior art must be obtained according to shell bore Size is equipped with the problem of inconvenient sex chromosome mosaicism that plurality of specifications clamp strap is come, and is reduced using the longevity because design is there are irrationality The problem of life, provides a kind of generally applicable elastic shell case clamps.

To achieve the goals above, the technical solution adopted in the utility model is as follows：

A kind of general clamps of elasticity shell case, including shell case fixed seat, fixed platform and fixing axle, the fixed platform are set It is placed in the fixing axle, the shell case fixed seat is set in the fixed platform, further includes an elastic element；The shell case Fixed seat by being mirrored into symmetrical left half of fixed seat and right half of fixed seat by being formed, in the left half of fixed seat and described Left spring mounting hole and right spring mounting hole, the elasticity member are respectively equipped on the opposite position in right one side of something fixed seat lower end two The both ends of part are respectively arranged in the left spring mounting hole and the right spring mounting hole；The general clamps of the elasticity shell case are also It is enclosed including dovetail mount and adjustment, the dovetail mount and adjustment circle may be contained in the fixed platform, and the shell case is fixed Seat is installed to by the dovetail cooperation of both sides in dovetail mount, and the adjustment circle is set to outside the dovetail mount, is enclosed in the adjustment Inner wall on two symmetrical positions be equipped with rotation boss, and be equipped with and rotation boss matching in the dovetail mount outer wall The groove of conjunction, when adjustment circle is rotated relative to the dovetail mount, under the action of the elastic element, described left one side of something Fixed seat and the right half of fixed seat are opposed, inwardly directed or be displaced outwardly, to change the left half of fixed seat and described right half The relative distance of side fixed seat, to be clamped or unclamp to shell bore.

Preferably, the elastic element is compression spring.

In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：

1. the utility model shell case clamps can be fixed by the left half of fixed seat and right one side of something that adjust shell case fixed seat The relative distance of seat, realizes its versatility, and the shell case fixture for solving the prior art must must be equipped with according to the size of shell bore The inconvenient sex chromosome mosaicism that plurality of specifications clamp strap is come.The shell case fixed seat of the utility model is fixed by left half of fixed seat and right one side of something Seat two half parts composition, it is internal that an elastic element is installed, using the elastic reaction of elastic element adjust left half of fixed seat and The relative distance of right one side of something fixed seat, to be clamped or unclamp to shell bore.Dovetail mount is equipped with outside shell case fixed seat successively With adjustment enclose, adjust circle inner wall be equipped with rotation boss, dovetail mount outer wall be equipped with the matched groove of the rotation boss, The effect of this design is that adjustment circle can push the opposed, inwardly directed movement of two half portion of shell case fixed seat when rotating, to shell case Endoporus is unclamped；Elastic force effect when adjustment circle reversely rotates in elastic element makes two half part of shell case fixed seat out against It is mobile, to be clamped to shell bore, to the shell case suitable for different size.

2. the design of the utility model shell case clamps shell case fixed seat adjustable-tightness also improve in background technology because The problem that installation inconvenience causes shell case clamps impaired.The utility model is suitable for the shell case of different size simultaneously, relative to biography The shell case fixture of system saves manufacturing cost to a certain extent.
