[0015] 1. The present invention is used in conjunction with a telescopic control component, a slide plate, a fixing block and a fixing belt. When in use, the slide plate can be controlled to move by the telescopic control component, so that the four slide plates can drive the fixing blocks and the fixing belts thereon to move. The positions of the fixing blocks and the fixing belts are adjusted according to the size of the mouse to ensure that the fixing belts can fix the limbs of mice of different sizes. Then, the mouse can be placed on the shell, and the limbs of the mouse are passed through the fixing belts. Then, the fixing belts are tightened so that the fixing belts and the slide plate cooperate to fix the limbs of the mouse. Then, the bolts are tightened so that one end of the bolts abuts against the fixing belts to fix the fixing belts. The fixing belts can be used repeatedly to fix the mouse by the fixing belts, thereby avoiding waste when using adhesive tapes for fixing. Moreover, the fixing belts are stably fixed. If the mouse wakes up during the ultrasonic irradiation experiment, it is difficult for the mouse to break free from the fixation of the fixing belts, thereby increasing the safety of the device.

[0016] 2. The present invention, by setting a rotating shaft, a transmission wheel and a first gear etc. for use in conjunction, a sliding nut can adjust the positions of the four slides to drive the fixing blocks and the fixing belts thereon, thereby making the use of the device convenient and simple. By setting a threaded hole and a screw rod etc. for use in conjunction, if the lengths of the mouse's limbs are different, the screw rod can be rotated to move outward from the threaded hole, the moving screw rod drives the slide to move, the moving slide drives the fixing belt to move, the moving fixing belt pulls the mouse's limbs, thereby stretching the mouse's limbs;

[0017] 3. The present invention, by setting the first stopper, the second stopper, the first direction mark and the second direction mark, etc. for use in conjunction, can rotate the swivel for adjustment to ensure that the device fully stretches the limbs of the mouse. As the force of the fixing belt pulling the limbs of the mouse increases, the force of rotating the swivel will gradually increase, which makes the length of the spring sheet pulled longer. After the length of the spring sheet increases to a certain position, the directions of the first direction mark and the second direction mark will gradually overlap. After the directions of the first direction mark and the second direction mark overlap, the rotating swivel should be released in time to avoid excessive force pulling the limbs of the mouse and injuring the mouse.

[0018] 4. In the present invention, after the force of the spring sheet relaxes after long-term use, the rotating block and the second pointing mark can be rotated to change the position of the second pointing mark, thereby changing the position where the first pointing mark and the second pointing mark overlap, so as to ensure that the device can stretch the mouse's limbs as much as possible without hurting the mouse, and avoid the problem that the mouse's limbs are not stretched apart after the first pointing mark and the second pointing mark overlap due to the relaxation of the spring sheet.
