[0030] An adjusting rod 6 is fixedly mounted on the inner wall of the lower end of the screw cap 2 , a square rod 7 is sleeved on the outer wall of the adjusting rod 6 , and a positioning frame 8 is fixedly connected to the end of the square rod 7 .

[0031] A servo motor 9 is fixedly provided on the end face of the positioning frame 8, and a transmission rod 10 is fixedly connected to the end of the output shaft of the servo motor 9. The outer walls of both ends of the transmission rod 10 are respectively sleeved with sleeves 11, and the upper surface of the sleeve 11 is fixedly connected to a positioning rod 12. A clamping arm 13 is fixedly provided on the outer wall of the side of the end of the positioning rod 12, and a soft pad 14 is bonded to the outer wall of the clamping arm 13.

[0032] The gripping rod 1 and the screw cap 2 in this example form a rotating structure, the gripping rod 1 and the square rod 7 are slidably connected, and the square rod 7 and the adjusting rod 6 are threadedly connected, so that the user can rotate the screw cap 2 so that the screw cap 2 drives the adjusting rod 6, and as the adjusting rod 6 rotates, the square rod 7 slides along the adjusting rod 6 and the gripping rod 1, thereby adjusting the length of the device, making it easier for the device to be inserted into containers of different sizes for use.

[0033] The limiting mechanism 5 in this example includes a knob 501 and a tooth plate 502. The knob 501 is movably mounted on the inner wall of the positioning arm 4. The end of the knob 501 is movably connected to the tooth plate 502, which facilitates limiting the screw cap 2 through the limiting mechanism 5 to prevent the screw cap 2 from loosening and affecting the normal use of the device.

[0034] The knob 501 and the positioning arm 4 in this example are threadedly arranged, the knob 501 and the tooth plate 502 are rotationally connected, the tooth plate 502 and the tooth protrusion 3 are meshed, and the tooth plate 502 and the positioning arm 4 are slidingly arranged, so that the user can rotate the knob 501 to move the knob 501 relative to the positioning arm 4, thereby driving the tooth plate 502 to move relative to the positioning arm 4, and then the tooth plate 502 moves to mesh with the tooth protrusion 3, completing the limiting of the tooth protrusion 3 and the screw cap 2.

[0035] The positioning frame 8 and the transmission rod 10 in this example are rotatably arranged, and the positioning frame 8 and the positioning rod 12 form a sliding structure, which facilitates the servo motor 9 to drive the transmission rod 10 to rotate relative to the positioning frame 8 and facilitates the positioning rod 12 to slide relative to the positioning frame 8.

[0036] The transmission rod 10 and the sleeve 11 in this example are threadedly connected, and the direction of the thread arranged on the outer wall of the transmission rod 10 is symmetrically distributed about the longitudinal center axis of the positioning frame 8, so that when the transmission rod 10 rotates, the sleeve 11 moves toward each other along the transmission rod 10 at the same time, thereby driving the positioning rod 12 to move, so that the clamping arms 13 move toward each other at the same time to clamp the experimental mouse.

[0037] Working principle: According to Figure 1-6 As shown, the user adjusts the length of the device according to the size of the container. At this time, the user holds the gripping rod 1 with one hand and rotates the screw cap 2 with the other hand. Then the screw cap 2 drives the adjusting rod 6 to rotate. Then the square rod 7 moves along the adjusting rod 6 and the gripping rod 1, thereby adjusting the length of the device, which makes it easier for the user to insert the device into containers of different sizes for use, thereby improving the practicality of the device. When the length of the device is adjusted, the user rotates the knob 501, and then the knob 501 moves relative to the positioning arm 4. Next, the knob 501 drives the tooth plate 502 to move relative to the positioning arm 4, and as the knob 501 continues to rotate, the tooth plate 502 finally engages with the tooth protrusion 3, thereby completing the screw cap 2 and The tooth protrusion 3 is limited, and then the user holds the gripping rod 1 to extend the clamping arm 13 into the container and close to the experimental mouse. When the clamping arm 13 moves to both sides of the experimental mouse, the user starts the servo motor 9, and then the servo motor 9 drives the transmission rod 10 to rotate relative to the positioning frame 8, and then the sleeve 11 moves toward each other along the transmission rod 10 at the same time, and then the sleeve 11 drives the positioning rod 12 to slide relative to the positioning frame 8, and then the positioning rod 12 drives the clamping arm 13 and the soft pad 14 to move, and as the transmission rod 10 continues to rotate, the clamping arm 13 finally drives the soft pad 14 to fit the experimental mouse, thereby completing the clamping of the experimental mouse, and then the user moves the device to drive the experimental mouse away from the container, thereby completing the clamping of the experimental mouse.
