Abstract

The invention relates to a fixing device which can effectively fix a white rat, is suitable for operations such as gavage and injection, and can also prevent people from being bitten by the white rat. The fixing device comprises a clamp and a spring, the clamp rotates around a central shaft and can be naturally opened by the spring, arc-shaped teeth for fixing the white rat are arranged on two sides of the lower surface of the clamp, the fronts of the teeth are short while the backs of the teeth are long, and a handheld arm is arranged on the upper surface of the clamp. The fixing device has the advantages of simple structure, convenience in operation, safety, reliability and high practicability, and is suitable for the animal experiment process.

Description

A kind of hand-held fixer for rattus norvegicus

Technical field

The present invention be more particularly directed to a kind of hand-held fixer for rattus norvegicus.

Background technology

At present in experimentation, with hands, capture and fixing rat, usually there is the thing of being bitten by rat to occur, or there is a kind of feared state of mind, be unfavorable for zooperally normally carrying out, in three grades of animals, level Four animal (germfree animal) feeding and management process, require staff directly not contact animal with hands in addition.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of can solve bitten and can be better fixing animal, be convenient to zooperal hand-held fixer for rattus norvegicus.

The technical scheme that realizes above-mentioned purpose is: a kind of hand-held fixer for rattus norvegicus, by the clip that can rotate around central shaft be arranged on the spring that can make clip naturally open on clip and form, it is characterized in that, below clip, both sides are the fixing tooth of rat, have certain interval between tooth and tooth, and the tooth on both sides can intersect when fixing animal, the front flank on both sides is shorter, after longer, each tooth is all camber, clip be above the arm of handgrip part.

Further, can pass through the position of nut regulating tooth on clip.

Further, on tooth, cover has and has elastic rubber or plastic sheath.

Further, by flute profile button fixing arm.

The invention has the advantages that, simple in structure, easy to operate, safe and reliable, practical.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The specific embodiment

In order to further illustrate the present invention, below in conjunction with accompanying drawing, further describe:

As shown in Figure 1, the present invention can make the spring 2 that clip opens naturally be comprised of the clip that can rotate around central shaft 1 with being arranged on clip, below clip, both sides are the fixing tooth 4 of rat, every toothrow can arrange 8-9 tooth, between tooth and tooth, there is certain interval, and the tooth on both sides can intersect when fixing animal, consider that the thin rear body of rat predecessor is thick, the tooth on both sides is also shorter above, after longer, each tooth 4 is all camber, can pass through nut 6 positions of regulating tooth 4 on clip, for preventing that animal is damaged, on the tooth 4 of contact animal, cover has and has elastic rubber or plastic sheath 5.Above clip, be the arm of handgrip part, by flute profile button 3 fixing arms.

During use, experimenter pinches rat tail tractive backward gently with a hands thumb and forefinger, another hands is taken holder, holder opens clip naturally by central shaft and spring, be placed on rat back and firmly grasp animal, rat forelimb is in the first neutral gear, even if rat forelimb is stuck in above between the first tooth and the second tooth, hands tightens up holder, by flute profile button, fixed, in the time of fixedly, note appropriateness and pass through the position of nut regulating tooth on clip, with animal, can not move forward and backward or left-right rotation is as the criterion, finally adjust the extremity of animal, it is more suitable for and experimental implementation, as anesthesia, gavage, injection, blood sampling etc.

The present invention can adopt stainless steel tube material or other light-duty hard material, can carry out high temperature, high pressure, medicine sterilization.

Claims

1. a hand-held fixer for rattus norvegicus, by the clip that can rotate around central shaft be arranged on the spring that can make clip naturally open on clip and form, it is characterized in that, below clip, both sides are the fixing tooth of rat, have certain interval between tooth and tooth, and the tooth on both sides can intersect when fixing animal, the front flank on both sides is shorter, after longer, each tooth is all camber, clip be above the arm of handgrip part.

2. a kind of hand-held fixer for rattus norvegicus as claimed in claim 1, is characterized in that, can pass through the position of nut regulating tooth on clip.

3. a kind of hand-held fixer for rattus norvegicus as claimed in claim 1, is characterized in that, on tooth, cover has and has elastic rubber or plastic sheath.
