[0002] Biological experiments refer to scientific research conducted in laboratories using animals in order to gain new knowledge about biology, medicine, etc. or to solve specific problems. Animal experiments must be conducted by or under the guidance of trained personnel with research degrees or professional technical capabilities.

[0003] In existing biological experiments, experimenters need to grab animals in cages to carry out the experiment. In order to prevent animals from causing harm to humans, personnel often use grabbing clamps to grab them. For example, the grabbing clamp published in announcement number CN204292067U can be used for experimental animals. When grabbing animals with existing similar grabbing devices, the applicant found that: when grabbing animals, personnel's hands need to continue to exert force to maintain the clamping state, which is very laborious. In addition, if the animal struggles during the grabbing process, the animal can break free if the personnel are not careful. The safety of grabbing needs to be improved. In order to solve the above problems, an animal fixing fork for biological experiments is proposed. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The following will be combined Figure 1-Figure 3 An animal fixing fork for biological experiments according to an embodiment of the utility model is described in detail.

[0020] Example:

[0021] The utility model embodiment provides an animal fixing fork for biological experiments, referring to Figure 1 As shown, it includes an inner rod 1, one end of which is staggered and rotatably connected to two semicircular clamps 2, the outside of the inner rod 1 is slidably connected to a push tube 3, one end of the push tube 3 is rotatably connected to two connecting rods 4, the two connecting rods 4 are rotatably connected to the two semicircular clamps 2 respectively, and a locking mechanism 5 is arranged between the push tube 3 and the inner rod 1. The above structure constitutes a fixed fork for experimental animals. In specific use, a person drives the connecting rod 4 to push and pull the semicircular clamps 2 by pulling the push tube 3 back and forth, so that the two semicircular clamps 2 rotate on the inner rod 1, thereby realizing the opening and merging of the semicircular clamps 2, and then realizing the clamping and opening of the animal's thoracic cavity, thereby realizing the grasping of the experimental animal. The entire grasping device can lock the clamping state of the semicircular clamps 2 through the locking structure 5, so that no manpower is required to maintain the clamping state, and the animal will not loosen when struggling. It is safer to use and more labor-saving and convenient.

[0022] refer to Figure 1 As shown, a plastic cushion 6 is provided on the inner side wall of the semicircular clamp 2, and the plastic cushion 6 of this structure prevents scratches on the animal.

[0023] refer to Figure 1 As shown, one end of the inner rod 1 is fixedly connected to a hand grip 7. This structure uses the hand grip 7 to facilitate personnel to hold the inner rod 1, thereby facilitating the capture of experimental animals.

[0024] refer to Figure 2 and Figure 3As shown, the locking mechanism 5 includes a plurality of locking holes 8 and a push handle 9. The locking holes 8 are provided on the inner rod 1, and the locking holes 8 are arranged on the inner rod 1 at equal intervals. A pressing handle 10 is movably connected to one side of the push handle 9, and a pull rod 11 is rotatably connected to one end of the press handle 10. A pressing block 12 is fixedly connected to one end of the pull rod 11, and a latch 13 is fixedly connected to the pressing block 12. The latch 13 passes through the side wall of the push tube 3, and the latch 13 is adapted to be plugged in the locking hole 8. A spring 14 is inserted into the outer wall of the pull rod 11, and a partition 15 is provided inside the push handle 9. The spring 14 is provided between the partition 15 and the pressing block 12. In this structure, the pull rod 11 passes through the partition 15. The staff holds the push handle 9 and presses the pressure handle 10 at the same time. At this time, the pressure handle 10 will pull the pull rod 11, and the pull rod 11 will drive the pressure block 12 to overcome the pressure of the spring 14, so that the latch 13 is separated from the existing rubbing lock hole 8. Then the staff can push and pull the push tube 3 back and forth to open and close the semicircular clamp 2. When the two semicircular clamps 2 reach the required opening and closing degree, the staff can release the pressure handle 10. At this time, under the elastic force of the spring 14, the latch 13 is automatically inserted into the lock hole 8 at the corresponding position, thereby locking the opening and closing angle of the semicircular clamp 2;

[0025] The above structure adopts the design of multiple locking holes 8 so that the semicircular clamp 2 can be freely adjusted to a suitable clamping position according to the size of the animal, thereby improving the versatility and practicality of the entire fixing fork.

[0026] refer to Figure 3 As shown, a square hole 16 is opened on one side of the push handle 9, and a shaft column 17 is fixedly connected to the inner wall of the square hole 16. A waist-shaped hole 18 is opened on one side of the pressing handle 10, and the shaft column 17 passes through the waist-shaped hole 18. In this structure, the pressing handle 10 is connected to the shaft column 17 of the push handle 9 through the waist-shaped hole 18, thereby realizing the connection between the pressing handle 10 and the push handle 9, and the waist-shaped hole 18 connection method provides a movable space for the up and down displacement of the pressing handle 10 when it rotates, thereby realizing the normal downward pressing of the pressing handle 10.

[0027] It should be noted that the fixed fork disclosed in the above embodiment is used for grabbing biological experimental animals.

[0028] The implementation principle of an animal fixing fork for biological experiments in an embodiment of the present application is as follows: when in use, a person clamps the two opened and closed semicircular clamps 2 in the thoracic part of the animal to be grasped, and then the person holds the push handle 9 and presses the pressing handle 10 at the same time. At this time, the pressing handle 10 will pull the pull rod 11, and the pull rod 11 will drive the pressing block 12 to overcome the pressure of the spring 14, so that the latch 13 is disengaged from the existing rubbing lock hole 8, and then the person pushes the push tube 3 forward, and the push tube 3 drives the connecting rod 4 to push and pull the semicircular clamps 2, so that the two semicircular clamps 2 rotate on the inner rod 1, so that the two semicircular clamps 2 are close to each other, and then the thoracic part of the experimental animal is clamped, and at this time the person can release the pressing handle 10, and at this time, under the elastic force of the spring 14, the latch 13 is automatically inserted into the locking hole 8 at the corresponding position, thereby locking the opening and closing angle of the semicircular clamp 2, and then the person can directly grab the animal through the inner rod 1, and the reverse operation can release the animal.
