[0020] like Figure 1~Figure 5As shown, a placement barrel for injection includes a barrel body 1, both ends of the barrel body 1 are open, one end of the barrel body 1 is provided with an end cap 10, a movable rod 16 is passed through the end cap 10, and a restraining disk 17 is provided at the inner end of the movable rod 16, and the restraining disk 17 is located inside the barrel body 1. A shrink tube 11 is coaxially provided on the end cap 10, and a tapered hole 12 is formed at the inner end of the shrink tube 11, and the inner end of the tapered hole 12 is a small end. A restraining tube 13 is screwed on the shrink tube 11, and the restraining tube 13 is sleeved on the movable rod 16. A tapered surface is formed at the inner end of the restraining tube 13, and the tapered surface acts on the inner wall of the tapered hole 12. A rotating ring 14 is provided at the outer end of the restraining tube 13, and a plurality of shrinkage seams 15 are provided on the restraining tube 13.

[0021] The other end of the cylinder 1 is provided with an end ring 3, on which two pairs of guide screws 30 are symmetrically provided, and a movable plate 31 is movably provided on each pair of guide screws 30, and a semicircular plate 33 is provided at the inner end of the movable plate 31. A spreading rod 34 is provided on the movable plate 31, and a moving plate 38 is sleeved on the spreading rod 34, and an inclined hole 40 is opened on the moving plate 38, and the long end direction of the inclined hole 40 and the length direction of the moving plate 38 are at an angle, and the spreading rod 34 passes through the inclined hole 40, and a pair of through rods 36 are provided at one end of the moving plate 38, and an outward pull end plate 37 is provided at the outer end of the through rod 36, and an end guide plate 35 is sleeved on the through rod 36, and the end guide plate 35 is installed on the end ring 3, and a spring 39 is provided on the inner side of the end guide plate 35, and the spring 39 is sleeved on the through rod 36.

[0022] A semicircular notch is provided on the cylinder 1, and a circle of enclosing plates 18 is provided at the periphery of the semicircular notch. An arc plate 2 is provided at the semicircular notch, and a circle of inserting rings is provided at the periphery of the arc plate 2. The inserting rings are located on the inner side of the enclosing plates 18. A plurality of clamping plates 20 are provided on the inserting rings, and the clamping plates 20 are L-shaped structures, and the lower ends of the clamping plates 20 are clamped on the horizontal section of the enclosing plates 18.

[0023] When operating the present embodiment, the arc plate 2 is first removed, and the white mouse is placed in the cylinder 1.

[0024] Then, the tail of the mouse is passed through the semicircular plates 33. When passing through, the outward-pulling end plate 37 is first pulled outward to move the movable plate 38 outward. At the same time, the movement of the movable plate 38 will cause the inclined hole 40 to act on the opening rod 34, thereby causing the movable plate 31 to move outward and the semicircular plates 33 to open. The tail is then passed through it. When the root of the tail is located at the semicircular plates 33, the pulling force on the outward-pulling end plate 37 is canceled, and then the tail is constrained by the semicircular plates 33.

[0025] Then, the operator buckles and fixes the arc plate 2 at the semicircular notch.

[0026] Finally, the position of the restraint disk 17 is adjusted by the movable rod 16 to restrain the activity range of the mouse through the restraint disk 17, and then the restraint tube 13 is rotated so that the conical hole 12 acts on the inner end of the restraint tube 13, and the movable rod 16 is fixed through the restraint tube 13. After the fixation is completed, the tail injection operation is performed.
