Abstract

The utility model relates to a rat trapper, include by round pin axle articulated dual tactics handle that sell the epaxial torsional spring that is equipped with, suppress in the inboard of corresponding handle at the both ends of torsional spring, arbitrary handle is all through a connecting plate and grip block fixed connection, the appearance chamber of two grip block inboards for being used for the centre gripping rat, just the cross -section of grip block is convex. This device has reduced the seizure degree of difficulty of rat through the brand -new structure of design to can prevent that the experimenter from being bitten by the rat.

Description

A kind of rat catcher

Technical field

This utility model relates to animal experiment device field, specifically, relates to a kind of rat catcher.

Background technology

Utilizing rat to carry out in zooperal process at present, the seizure of rat is the thing of comparatively difficulty.Male rat body weight is many between 200-400g, has higher aggressivity.Carry out, in the process of rat seizure, mostly being experimenter and wearing mitten, capture rat.However, experimenter's situation of being bitten by rat is of common occurrence.

Due to rat move, the effect of the multiple factors such as experimenter's phychology is nervous, fear, rat catches often cannot once success, needs repeatedly to capture.And after catching failure for the first time, rat can be appreciated that danger, presents the state that head lifts, and in capture-process subsequently, can launch a offensive to experimenter, causes experimenter's hand to be bitten.

Meanwhile, the rat under panic states, is in stress state, and its hormone in vivo diacrisis, have impact on the accuracy of experimental result to a great extent.

Utility model content

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of rat catcher.This device, by designing brand-new structure, reduces the seizure difficulty of rat, and can prevent experimenter from being bitten by rat.

In order to reach above-mentioned purpose, this utility model adopts following technical scheme:

A kind of rat catcher, comprise by two handles of hinge, bearing pin is provided with torsion spring, and the inner side in corresponding handle is suppressed at the both ends of torsion spring; Arbitrary handle is all fixedly connected with grip block by a plate, be the cavity volume for clamping rat, and the cross section of described grip block is circular arc inside two grip blocks.

Preferably, the inner side of arbitrary grip block is all bonded with cushion pad.

Preferably, described cushion pad is silica gel material.

Preferably, described grip block is stainless steel.

Preferably, described connecting plate is stainless steel.

Preferably, described two grip blocks close the American football shape structure of rear formation both ends open.

Preferably, described grip block is that top is high, the streamlined structure that two ends are low.

The beneficial effects of the utility model are: experimenter by the seizure of this device realization to rat, can catch success rate high, and not easily bitten by rat.

Accompanying drawing explanation

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

Fig. 2 is that the A-A of Fig. 1 is to sectional view (part more than not shown connecting plate);

In figure: 1, handle, 2, connecting plate, 3, grip block, 4, torsion spring, 5, cushion pad.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in detail.

Embodiment 1: a kind of rat catcher, as shown in Figure 1-2, comprise by two handles 1 of hinge, bearing pin is provided with torsion spring 4 to its structure, and the inner side in corresponding handle 1 is suppressed at the both ends of torsion spring 4; Two handles 1 are fixedly connected with corresponding grip block 3 respectively by a plate 2, be the cavity volume for clamping rat, and the cross section of described grip block 3 are circular arc inside two grip blocks 3.

The inner side of arbitrary grip block 3 is all bonded with cushion pad 5, and cushion pad 5 is silica gel material, and the rat when torsion spring 4 active force is larger can be prevented injured.

Described grip block 3 is stainless steel, and described connecting plate 2 is also stainless steel, makes this device comparatively firm.

Form the American football shape structure of both ends open after described two grip blocks 3 are closed, and grip block 3 is that top is high, the streamlined structure that two ends are low.So that the mouth of rat and tail expose, be also convenient to push down rat head, prevent rat from coming back and sting people.The body curvature of American football shape structure and rat is comparatively approximate, rat can be made comparatively natural by what clamp, prevent rat hypertonicity, cause endocrine to differ from usually.

During use, with hands grips said handle 1, then grip block 3 just opens, and is then buckled in by grip block 3 with it rat, and slightly loosen handle 1, then torsion spring 1 will suppress handle 1, and accordingly, grip block 3 will relative medial movement, and rat is just booked.

Upset arm, then rat just presents belly state upwards, is convenient to injection injection and tests with next step.

To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses this utility model.To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can when not departing from spirit or scope of the present utility model, realize in other embodiments, the part be not described in detail, for prior art, do not repeat at this.Therefore, this utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and feature.
