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 o

Embodiment 1
[0030] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a variable square fixer of the present invention. The fixer is provided with a base 1, a moving baffle 2, a fixed barrel body 3, and a moving barrel body 4; On the side of the bar, the two form a circular arc cavity in the middle, and the upper openings of the two are not closed; the side walls of the fixed cylinder body 3 and the mobile cylinder body 4 are respectively provided with two through grooves 5, four The position of the through groove 5 corresponds to the position of the limbs of the rat; screw holes and screws 11 are also provided on the base 1 .
[0031] Please refer to figure 2 , figure 2 It is a structural schematic diagram of a movable baffle in a variable square fixer of the present invention. The mobile baffle is provided with a fixed board 21 and a stepped support plate 22; the fixed board 21 is circular, and a mouse tail groove 24 is provided below; the upper end of th...

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...
