Changeable square fixing device

Abstract

The invention relates to a changeable square fixing device. The fixing device is provided with a base, a movable baffle, a fixed cylindrical body and a movable cylindrical body. The fixed cylindrical body and the movable cylindrical body are located on the base, and an arc-shaped cavity is formed between the fixed cylindrical body and the movable cylindrical body. The movable cylindrical body is provided with a radial sliding rail, and the sliding rail is matched with a radial sliding block on the base and can accordingly move on the base in the radial direction. One end of the fixed cylindrical body is provided with a tapered limiting plate. The movable baffle is provided with a fixing inserting plate and a stepped supporting plate. A U-shaped groove and a movable guide rail are arranged at the upper end and the lower end of the stepped supporting plate respectively. The movable baffle can axially move on the base through match of the movable guide rail and an axial sliding block of the base. The fixing inserting plate is provided with a rat tail groove and is embedded in the arc-shaped cavity between the fixed cylindrical body and the movable cylindrical body. The changeable square fixing device has the advantages that different sizes of rats can be fixed by adjusting the fixed space, the fixed rat body can be exposed outside, experiment research is facilitated, and the fixing device is simple in structure and reliable in fixing.

Description

technical field [0001] The invention relates to the field of animal experiment equipment, in particular to a variable square fixer. Background technique [0002] Experimental small animals, such as rats, play an important role in TCM experiments. During the experiment, it is usually necessary to fix the body of the experimental small animal. For example, during the massage experiment, the accuracy of the massage simulation experimental equipment to stimulate the acupuncture points of the experimental small animal has a great impact on the analysis of the experimental results, so the fixation of the experimental small animal is very important. . At the same time, due to the needs of different experiments, it is necessary to conduct experiments on experimental small animals of different sizes and ages, and the experimental small animal fixer with a constant size cannot meet the experimental small animal experiments with body size as a variable. [0003] In the prior art, the...

Problems solved by technology

At the same time, due to the needs of different experiments, it is necessary to conduct experiments on experimental small animals of different sizes and ages. The experimental small animal fixer with an invariable size cannot meet the experimental small animal experiments with body size as a variable.

[0003] In the prior art, the fixer for rats usually fixes the rats in a closed space, and the fixed space cannot be changed. Rats of different sizes cannot be fixed in the same device, so the research on rats has great potential. Large limitations, such as rat massage experiments can not use this fixator

[0004] In summary, there is an urgent need for a fixator that can be applied to rat massage experiments, has a simple structure, is fixed firmly, has a variable fixation space, and can expose the body of the rat, but there is no report about this fixator yet.
