Technical Field

The invention belongs to the technical field of animal science experiments, and particularly relates to a device for stimulating the nerve of the thigh of a rat.

Background

In the laboratory, different kinds of mouse can often be used, carry out scientific experiment, the rat is wherein common one, can use the rat to carry out the amazing experiment of leg femoral nerve in the laboratory, but in current experimentation, need fixed rat back usually, experiment again, but present general direct putting on the laboratory bench, stability that can not be fine, and when amazing leg femoral nerve, also convenient full convenient shrink reaction of observing amazing in-process of also making things convenient for the experimenter to its fine observation.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a device for stimulating the leg and femoral nerves of rats, which can well fix the rats with different body types; meanwhile, the device can be adjusted according to the body length difference of different rats.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a device for rat thigh nerve is amazing, is including supporting the base, it is provided with the supporting shoe No. one to support the base top, supporting shoe top end-to-end connection has a bearing No. one, and a bearing surface has cup jointed a carousel No. one, it is provided with the carousel No. two to support the base top, No. two carousel tops are provided with branch, the inside carousel that rotates through No. one of branch is connected, branch one side end is through fixed block of screw fixedly connected with No. one, inside there is No. four fixed blocks through a plurality of spring elastic connection of fixed block, the terminal welding has No. two fixed blocks and No. three fixed blocks in branch below respectively.

According to the preferred technical scheme of the device for stimulating the nerve of the thigh of the rat, the four supporting blocks are arranged above the supporting base, the upper surfaces of the four supporting blocks are welded with the lower surface of the first supporting block, the inside of the four supporting blocks is fixedly connected with the second rotating shaft through the support, the outer surface of the second rotating shaft is sleeved with the second rotating disc, the inside of the supporting base is penetrated with the bolt, and the upper surface of the bolt is welded with the lower surface of the second rotating disc through the plurality of the second supporting blocks.

As the preferable technical scheme of the device for stimulating the nerve of the thigh of the rat, a groove is formed in the first fixing block.

As a preferred technical scheme of the device for stimulating the nerve of the thigh of the rat, suckers are arranged at four corner positions below the supporting base.

As the preferable technical scheme of the device for stimulating the nerve of the thigh of the rat, a third supporting block is welded on one side of the outer surface of the bolt, and an integrally-formed handle is welded on the lower surface of the third supporting block.

As the preferable technical scheme of the device for stimulating the nerve of the thigh part of the rat, the outer surface of the No. four fixing block is provided with transverse striations.
