[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 3 The rat fixing device of the utility model comprises a base 1, on which a fixing cylinder for storing and fixing rats is installed, and the fixing cylinder comprises two arc-shaped gusset plates 2 symmetrically arranged and installed on the base 1, and the same ends of the two arc-shaped gusset plates 2 close to the base 1 are rotatably connected to the base 1 through a rotating component 21, and the fixing cylinder can be opened by rotating the two arc-shaped gusset plates 2 with the rotating component 21 as an axis;

[0027] The fixing tube also includes a covering film 3 located between the two arc-shaped gusset plates 2, and the covering film 3 is used to block the gap between the two arc-shaped gusset plates 2 when rotating;

[0028] One end of the arc-shaped gusset plate 2 on which the rotating component 21 is installed is a rotating end, and the other end is a movable end.

[0029] The covering film 3 is designed in a fan shape or a triangle shape, the central angle of the covering film 3 is connected to the rotating ends of the two arc-shaped gusset plates 2, and the two ends of the arc edge of the covering film 3 are respectively installed on the two arc-shaped gusset plates 2 through tightening components 4.

[0030] The tightening component 4 includes a reel 41 , on which an arc edge end point corresponding to the covering film 3 is wound. The reel 41 is rotatably mounted on the outer side of the arc-shaped gusset plate 2 through a bearing seat along the central axis direction of the fixed tube.

[0031] The rotating component 21 may be a rotating shaft or a clockwork rotating shaft;

[0032] A locking mechanism 5 for locking the angle of the arc-shaped gusset plate 2 after rotation is installed on the fixing cylinder.

[0033] Specifically, the locking mechanism 5 is a buckle 53 installed on the arc-shaped buckle plate 2 and a corresponding snap-fit ​​seat 51 installed on another arc-shaped buckle plate 2. A spring 54 is provided on the opening of the buckle 53, and a clamping block 55 is provided at the bottom of the spring 54. A fitting groove 52 for the buckle 53 to fit is provided on the snap-fit ​​seat 51, and a clamping hole for the clamping block 55 to fit is also provided on the snap-fit ​​seat 51.

[0034] In this example:

[0035] The two arc-shaped buckle plates 2 constituting the fixed tube are rotated to open by the rotating part 21 respectively, and the covering film 3 is opened by the pulling of the rotating arc-shaped buckle plates 2. When the device forms a trumpet-shaped opening, the buckle 53 in the locking part enters the fitting groove 52 and enters the card hole on the card seat 51 through the card block 55 to engage, thereby locking the opening state of the device, and then the rat is placed inside the device, that is, the device facilitates the entry of the rat by changing the size of the entrance for accommodating the rat.

[0036] Embodiment 2:

[0044] This embodiment is different from the first and second embodiments in that the diameter of the fixing tube can be changed according to the body shape of the rat, so that it is more suitable for restraining and fixing the rat. When in use, the distance between the movable arc plate 6 and the arc buckle plate 2 can be changed by rotating the adjusting screw, so that the distance between the two movable arc plates 6 is more suitable for the rat.
