DETAILED DESCRIPTION

[0016] like Figure 1-Figure 3 As shown, an adjustable fixing device for animal experiments includes a fixed platform 1 and a movable platform 2 with flush top surfaces, the bottom of the fixed platform 1 is symmetrically provided with two groups of fixed legs 3, the bottom of the movable platform 2 is symmetrically provided with two groups of mounting legs 4, and the bottom of each mounting leg 4 is respectively provided with a running wheel 5. In this embodiment, the running wheel 5 is specifically configured as a self-locking wheel.

[0017] Two first mounting plates 6 are symmetrically fixedly arranged at one end of the fixed platform 1 close to the movable platform 2, a roller 7 is rotatably mounted between the two first mounting plates 6, one end of the central axis of the roller 7 extends to the outside of the corresponding first mounting plate 6 and is mounted with a first hand wheel 8. A support cloth 9 is wound around the peripheral wall of the roller 7, and the free end of the support cloth 9 is fixedly connected to the end of the movable platform 2.

[0018] Two groups of straps are symmetrically arranged on the upper parts of the fixed platform 1 and the movable platform 2 .

[0019] Two second mounting plates 10 are symmetrically arranged on both sides of the middle of the bottom of the fixed platform 1 and the movable platform 2, and a lead screw 11 is rotatably installed between the two second mounting plates 10. The lead screw 11 is specifically a double-headed lead screw with opposite rotation directions at both ends. One end of the lead screw 11 extends to the outside of the second mounting plate 10 at the corresponding end and is installed with a second hand wheel 12. Two sliders 13 are symmetrically installed on the two halves of the lead screw 11, and the lower half of each slider 13 is respectively provided with a threaded hole adapted to the external thread of the corresponding part of the lead screw 11, and the upper half of each slider 13 is respectively slidably matched with a limiting slide groove 14 provided on the fixed platform 1 or the movable platform 2, and each group of the binding straps is respectively arranged at the upper end of each slider 13.

[0020] In this embodiment, each group of the straps includes a first strap 15 and a second strap 16, one end of which is fixedly connected to the upper end of the slider 13, a buckle 17 is fixedly provided at the free end of the first strap 15, and a plurality of sockets 18 matching the buckle 17 are evenly opened at the free end of the second strap 16.

[0021] When the utility model is actually applied, the fixed platform, the movable platform and the support cloth between the two together constitute the support table surface for animal experiments. The distance between the two sets of straps can be increased by pulling and pushing the movable platform, so as to adapt to the body length characteristics of different animals. It should be noted here that after pushing the movable platform in the direction close to the fixed platform, the support cloth can be tightened by turning the first hand wheel. In addition, by turning the second hand wheel to drive the lead screw to rotate, the two sliders and the corresponding two sets of straps move toward or away from each other, so as to adapt to the arm span characteristics of different animals. The utility model is easy and quick to adjust, can fully fix animals of various sizes, and has good applicability and practicality.
