[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth mentioning that the bottom of the multiple electric telescopic rods 4 are fixedly connected with shock-absorbing pads. There may be vibrations and vibrations in the laboratory from equipment operation, personnel activities or external environment. The shock-absorbing pads can effectively absorb and reduce the impact of these vibrations on the device, thereby improving the accuracy and stability of monitoring; at the same time, the shock-absorbing pads are made of rubber material, which helps to reduce the impact of noise and vibration on the surrounding environment and improve the overall environmental quality of the laboratory.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the ball nut seat 8 and the two guide sleeves 9 are at the same horizontal height, and the ball nut seat 8 and the two guide sleeves 9 cooperate with each other so that the support plate 10 always maintains a stable state during the lifting process.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the output end of the servo motor 11 passes through the top of the convex frame 5 and is fixedly connected to the threaded rod 6, ensuring that the servo motor 11 can drive the threaded rod 6 to rotate stably, thereby providing driving force for the support plate 10 to drive the monitoring mechanism 12 to rise and fall.

[0026] According to the above working process, it can be known that: by setting the servo motor 11 to drive the threaded rod 6 to rotate, with the cooperation of the ball nut seat 8 and the guide sleeve 9, the support plate 10 drives the monitoring mechanism 12 to rise and fall, so that the monitoring mechanism 12 can monitor the environment at different heights in the laboratory, making the monitoring work more comprehensive, ensuring that the laboratory working environment meets the standards, and reducing safety hazards; at the same time, the pulley 2 and the electric telescopic rod 4 cooperate, so that the device can be flexibly moved and stably positioned, which greatly reduces the labor intensity of the staff.

[0027] Further as Figure 4 As shown, it is worth specifically explaining that the monitoring mechanism 12 includes two fixed plates 1201 fixedly connected to the top of the support plate 10, two positioning rods 1202 are slidably connected inside the two fixed plates 1201, and the outer walls of multiple positioning rods 1202 are sleeved with springs 1203, and the outer sides of every two corresponding positioning rods 1202 are fixedly connected with a pull plate 1204, and a monitoring instrument body 1205 is detachably connected between the two fixed plates 1201, and mounting blocks 1206 are fixedly connected on both sides of the monitoring instrument body 1205.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the outer wall of the positioning rod 1202 fits tightly with the inner wall of the positioning groove 1207. The tight fit can ensure the precise positioning of the monitoring instrument body 1205 during the installation process, reduce the interference caused by position movement or vibration of the equipment during operation, and thus improve the accuracy and reliability of the monitoring data.

[0030] This solution has the following working process: in actual use, the staff pushes the pulley 2 to move the device to the specified position, then turns on the electric telescopic rod 4 to lift the device into position, and then turns on the servo motor 11 to drive the threaded rod 6 to rotate, so that the ball nut seat 8 and the guide sleeve 9 cooperate to drive the support plate 10 to rise and fall, thereby driving the monitoring instrument body 1205 to rise and fall, so that it can monitor different height environments in the laboratory.

[0031] In summary: by setting the servo motor 11 to drive the threaded rod 6 to rotate, with the cooperation of the ball nut seat 8 and the guide sleeve 9, the support plate 10 drives the monitoring mechanism 12 to rise and fall, so that the monitoring mechanism 12 can monitor the environment at different heights in the laboratory, making the monitoring work more comprehensive, ensuring that the laboratory working environment meets the standards, and reducing safety hazards; at the same time, the pulley 2 and the electric telescopic rod 4 cooperate, so that the device can be flexibly moved and stably positioned, greatly reducing the labor intensity of the staff; by setting the monitoring mechanism 12, the detachable connection of the monitoring instrument body 1205 on the top of the support plate 10 is realized, which is convenient for the installation and disassembly of the monitoring instrument body 1205, saving maintenance time and repair costs.
