On one side of the grip 5, there is a limiting component 6 for limiting it. On one side of the support frame two 3, there is a support rod two 8. The support frame one 2 is rotatably connected to the support rod two 8. On the surface of the support rod two 8, there is a rotating sleeve 11 connected to the grip 5. On one side of the rotating sleeve 11, there is a toothed ring 12. On the other side of the grip 5, there is a locking component 7 for locking the toothed ring 12. By applying pressure to the locking component 7 to separate it from the toothed ring 12, the rotating sleeve 11 can be rotated, which can drive the support frame two 3 to rotate, thereby sealing the top of the net bag body 1. The support frame two 3 fits against the inner wall of the support frame one 2, and it is not easy to generate gaps, which can prevent the escape of the tree shrew;

[0026] In this embodiment, preferably, the limiting component 6 includes a convex shell 601 and a bearing 604. One side of the convex shell 601 is fixedly connected to one side of the grip 5.

[0029] In this embodiment, preferably, a pillar 17 is fixedly provided on the other side of the second support frame 3. The pillar 17 is rotatably connected to the other side of the first support frame 2. The other side of the second support frame 3 can be connected to the other side of the first support frame 2 through the pillar 17, and the second support frame 3 can perform a circular motion along the pillar 17.

[0030] When in use, by holding the handle 5 and the rotating sleeve 11 with both hands respectively, the first support frame 2 and the second support frame 3 can support the top end of the net body 1, preventing the top end of the net body 1 from collapsing, and thus enabling the capture of the tree shrew. After the tree shrew is captured, by pressing the lever 703 of the locking component 7 with fingers, the spring 704 is compressed, separating the toothed block 706 from the toothed ring 12. Then, the rotating sleeve 11 is rotated. The sliding groove 15 and the sliding block 16 enable the second support rod 8 to rotate synchronously with the rotating sleeve 11, driving the second support frame 3 to rotate. The second support frame 3 can fit against the inner wall of the first support frame 2, without easily generating gaps, blocking the top end of the net body 1 and preventing the tree shrew from escaping. Finally, the lever 703 is released, and the spring 704 can push the toothed block 706 back to its original position, engaging it with the toothed ring 12. Under the supporting force of the spring 704, the toothed ring 12 can be locked, preventing the rotating sleeve 11 and the second support frame 3 from rotating;

[0031] When it is necessary to release the tree shrew for experiments, the staff operates in the reverse direction to open the second support frame 3, and the tree shrew can be taken out from the net body 1. When it is necessary to adjust the length of the handle 5, the handle 5 is slid on the first support rod 4. The handle 5 can drive the rotating sleeve 11 to slide through the connecting sleeve 9, simultaneously adjusting the handle 5 and the rotating sleeve 11. After the adjustment is completed, by rotating the screw rod 603 through the knob 607 of the limiting component 6, the clamping block 605 is driven to move horizontally. The bearing 604 can prevent the torque of the screw rod 603 from being transmitted to the clamping block 605. The clamping block 605 can clamp the first support rod 4 through the curved surface groove 606. The rubber pad can increase the fitting degree and friction between the clamping block 605 and the first support rod 4, thereby limiting the handle 5. After use, the handle 5 and the rotating sleeve 11 are retracted, and then the second support frame 3 is rotated to the inner wall of the first support frame 2 for folding, which does not occupy space and is convenient for storage.
