[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] Please see Figure 1-8 This utility model provides a technical solution:

[0032] A biological experimental fixture includes an experimental table 1, on which tweezers 2 are mounted. The tweezers 2 are V-shaped, with tweezer tips 3 at both ends. A plug 4 is fixedly mounted at the top of the tweezers 2. A connecting block 5 is fixedly mounted on the experimental table 1, the size of the plug 4 being adapted to the size of the connecting block 5. A movable frame 6 is slidably mounted on the tweezers 2, the interior of the movable frame 6 being V-shaped, and the size of the movable frame 6 being adapted to the size of the tweezers 2. A sleeve 7 is fixedly mounted on the side of the movable frame 6. A spring 8 is installed inside the rod 7. A connecting rod 9 is slidably mounted on the sleeve rod 7. The two ends of the spring 8 are fixedly installed to the sleeve rod 7 and the connecting rod 9, respectively. A motor 10 is fixedly mounted on the experimental platform 1. A lead screw 11 is fixedly mounted at the end of the output shaft of the motor 10. A slide rail 12 is provided on the experimental platform 1. A slider 13 is slidably mounted on the slide rail 12. The slider 13 is threadedly connected to the lead screw 11. A connection port 14 is provided on the side of the slider 13. The size of the connection port 14 is adapted to the size of the end of the connecting rod 9.

[0033] In biological experiments, when automatically clamping the organism, the experimenter places the organism on the experimental table 1 and starts the motor 10 fixedly installed on the experimental table 1. The output shaft of the motor 10 drives the lead screw 11 to rotate. Since the slider 13, which is slidably set on the slide rail 12, is threadedly connected to the lead screw 11, the rotation of the lead screw 11 drives the slider 13 to move on the slide rail 12. When the slider 13 moves, it drives the sleeve 7 and the movable frame 6 to slide on the tweezers 2 through the connecting rod 9. The movable frame 6 is set with a V-shape inside and is adapted to the size of the tweezers 2. The sliding of the movable frame 6 causes the parts with tweezer tips 3 at both ends of the tweezers 2 to gradually close, thereby automatically clamping the organism.

[0034] If it is necessary to manually grasp the organism, the experimenter pulls the connecting rod 9 to compress the spring 8 and moves it into the sleeve rod 7. The end of the connecting rod 9 is pulled out from the connecting port 14 on the side of the slider 13. Then, the insert 4 is pulled out from the connecting block 5 to disassemble the tweezers 2. After disassembly, the movable frame 6 is pushed on the tweezers 2 by the sleeve rod 7, which causes the tweezers head 3 to gradually close and grasp the organism. After grasping, the stability of the grasping process can be improved due to the limitation of the movable frame 6, and there is no need to apply continuous force.

[0035] This biological experimental clamp has a dual operating mode. It can not only automatically clamp smaller organisms, but also remove the clamp separately to manually clamp the organisms. It is highly applicable, stable during the clamping process, and practical.

[0036] The tweezers 2 have movable openings 15 at both ends, and movable blocks 16 are slidably disposed on the movable openings 15. Damping is provided between the movable blocks 16 and the movable openings 15, and the tweezers head 3 is snapped onto the movable blocks 16.

[0037] When the height of the tweezers 3 needs to be adjusted, the height of the tweezers 3 can be adjusted by pushing the movable block 16 up and down on the movable opening 15. The movable block 16 and the movable opening 15 are provided with damping, so that the movable block 16 and the tweezers 3 can be kept in any position after adjustment. If a different size of tweezers 3 needs to be replaced, since the tweezers 3 is snapped on the movable block 16, the original tweezers 3 can be directly removed from the movable block 16 and the new tweezers 3 can be snapped on and installed. The easy replacement of tweezers 3 of different sizes improves the applicability of the device.

[0038] The tweezers 2 have graduations on the side of the movable opening 15;

[0039] The tweezers 2 have a scale on the side of the movable opening 15. When the experimenter pushes the movable block 16 to slide within the movable opening 15, he can intuitively understand the distance the movable block 16 moves according to the scale, so as to accurately adjust the height of the tweezers 3 and ensure the accuracy of the experimental operation.

[0040] A lever 17 is fixedly installed on the side of the connecting rod 9;

[0041] When it is necessary to pull the connecting rod 9 to retract, the experimenter only needs to pull the lever 17 with his finger to make the connecting rod 9 slide on the sleeve 7, which makes it easy to retract the connecting rod 9.

[0042] The tweezers 2 have a telescopic protrusion 18 on the side of their end;

[0043] During normal use, the telescopic protrusion 18 on the side of the end of the tweezers 2 is in a naturally extended state. When the movable frame 6 slides on the tweezers 2, the telescopic protrusion 18 will restrict the sliding range of the movable frame 6 to prevent the movable frame 6 from falling off the tweezers 2. When it is necessary to remove the movable frame 6, pull the telescopic protrusion 18 to retract it and release the restriction on the movable frame 6, so that the movable frame 6 can be easily removed from the tweezers 2.

[0044] Both the insert block 4 and the connecting block 5 are square, and there is a damping between the insert block 4 and the connecting block 5;

[0045] When installing tweezers 2, the square insert 4 fixedly installed at the top of tweezers 2 is inserted into the square socket fixedly installed on the experimental table 1. Since there is damping between the insert 4 and the socket, the insert 4 will be subject to a certain resistance after insertion, and it is not easy to shake. This improves the stability of tweezers 2 after installation and fixation, and further ensures that tweezers 2 will not easily shift or shake when holding organisms, thereby improving the stability of holding organisms.

[0046] Working principle:

[0047] In biological experiments, when automatically clamping the organism, the experimenter places the organism on the experimental table 1 and starts the motor 10 fixedly installed on the experimental table 1. The output shaft of the motor 10 drives the lead screw 11 to rotate. Since the slider 13, which is slidably set on the slide rail 12, is threadedly connected to the lead screw 11, the rotation of the lead screw 11 drives the slider 13 to move on the slide rail 12. When the slider 13 moves, it drives the sleeve 7 and the movable frame 6 to slide on the tweezers 2 through the connecting rod 9. The movable frame 6 is set with a V-shape inside and is adapted to the size of the tweezers 2. The sliding of the movable frame 6 causes the parts with tweezer tips 3 at both ends of the tweezers 2 to gradually close, thereby automatically clamping the organism.

[0048] If it is necessary to manually grasp the organism, the experimenter pulls the connecting rod 9 to compress the spring 8 and moves it into the sleeve rod 7. The end of the connecting rod 9 is pulled out from the connecting port 14 on the side of the slider 13. Then, the insert 4 is pulled out from the connecting block 5 to disassemble the tweezers 2. After disassembly, the movable frame 6 is pushed on the tweezers 2 by the sleeve rod 7, which causes the tweezers head 3 to gradually close and grasp the organism. After grasping, the stability of the grasping process can be improved due to the limitation of the movable frame 6, and there is no need to apply continuous force.

[0049] This biological experimental clamp has a dual operating mode. It can not only automatically clamp smaller organisms, but also remove the clamp separately to manually clamp the organisms. It is highly applicable, stable during the clamping process, and practical.

[0050] in,

[0051] When the height of the tweezers 3 needs to be adjusted, the height of the tweezers 3 can be adjusted by pushing the movable block 16 up and down on the movable opening 15. The movable block 16 and the movable opening 15 are provided with damping, so that the movable block 16 and the tweezers 3 can be kept in any position after adjustment. If a different size of tweezers 3 needs to be replaced, since the tweezers 3 is snapped on the movable block 16, the original tweezers 3 can be directly removed from the movable block 16 and the new tweezers 3 can be snapped on and installed. The easy replacement of tweezers 3 of different sizes improves the applicability of the device.

[0052] The end of the tweezers 2 has a scale on the side of the movable opening 15. When the experimenter pushes the movable block 16 to slide within the movable opening 15, he can intuitively understand the distance the movable block 16 moves according to the scale, so as to accurately adjust the height of the tweezers 3 and ensure the accuracy of the experimental operation.

[0053] When it is necessary to pull the connecting rod 9 to retract, the experimenter only needs to pull the lever 17 with his finger to make the connecting rod 9 slide on the sleeve 7, which makes it easy to retract the connecting rod 9.

[0054] During normal use, the telescopic protrusion 18 on the side of the end of the tweezers 2 is in a naturally extended state. When the movable frame 6 slides on the tweezers 2, the telescopic protrusion 18 will restrict the sliding range of the movable frame 6 to prevent the movable frame 6 from falling off the tweezers 2. When it is necessary to remove the movable frame 6, pull the telescopic protrusion 18 to retract it and release the restriction on the movable frame 6, so that the movable frame 6 can be easily removed from the tweezers 2.

[0055] When installing tweezers 2, the square insert 4 fixedly installed at the top of tweezers 2 is inserted into the square socket fixedly installed on the experimental table 1. Since there is damping between the insert 4 and the socket, the insert 4 will be subject to a certain resistance after insertion, and it is not easy to shake. This improves the stability of tweezers 2 after installation and fixation, and further ensures that tweezers 2 will not easily shift or shake when holding organisms, thereby improving the stability of holding organisms.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
