[0028] In this embodiment, a groove 1 is provided at one end of the movable plate 8, and a magnetic block 2 12 is fixedly installed in the groove 1. A groove 2 is provided on the fixed plate 2 9, and a magnetic block 11 is fixedly installed in the groove 2. The magnetic block 11 and the magnetic block 2 12 attract each other, and the force between the magnetic block 11 and the magnetic block 2 12 can achieve a certain support effect on one end of the movable plate 8, thereby preventing the movable plate 8 from rotating when the rat's front paw moves onto the movable plate 8, thereby achieving the effect of preventing the rat from being frightened.

After that, the baffle 15 is pulled upward to make the baffle 15 release the obstruction of the through hole 5, and at the same time, the rat is lured by the rat bait in the bait dish 10, so that the rat passes through the exit of the mouse cage and the through hole 5 and enters the rat weighing box body 1, and the rat moves toward the bait dish 10. In this process, when the rat moves to the moving plate 8, the moving plate 8 is rotated on the fixed rod 7 by a certain angle due to the action of the rat's own weight, and the return spring is charged, so that the rat slides from the moving plate 8 to the electronic scale 2 for rats. When the rat leaves the moving plate 8, the moving plate 8 is restored to its original state by the action of the return spring, thereby achieving the effect of weighing the rat.

[0037] After the rat is weighed, the cage is placed on the second placement plate 17, and the entrance of the cage is aligned with the second through hole 13. Then, the second baffle 19 is pulled upward to separate the baffle 19 from blocking the second through hole 13. Then, the rat passes through the second through hole 13 and the entrance of the cage and enters the cage, thereby achieving the effect of recovering the rat.

[0038] The acting force between the magnetic block 11 and the magnetic block 2 12 can provide a certain support effect on one end of the movable plate 8, thereby preventing the movable plate 8 from rotating when the rat's front paw moves onto the movable plate 8, thereby preventing the rat from being frightened.

[0039] The technical progress achieved by the utility model compared with the prior art is that the rat can be weighed through the cooperation of various components, and the result is simple and easy to operate, thereby improving the accuracy of rat weighing and having higher practicality.
