[0023] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the limiting mechanism includes a limiting rod 15 fixed to one side of the L-shaped mounting plate 1, a stopper 17 is fixed to the end of the limiting rod 15, a connecting rod 12 is slidably sleeved on the outer surface of the limiting rod 15, two symmetrically distributed plug rods 18 are fixed on one side of the connecting rod 12, the plug rods 18 are plugged into the socket 20, and a spring 16 is sleeved on the outer surface of the limiting rod 15, one end of the spring 16 is fixed to the surface of the connecting rod 12, and the other end of the spring 16 is fixed to the surface of the stopper 17.

[0024] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth explaining in detail that the protection mechanism includes two mounting rods 4 fixed to the surface of the L-shaped mounting plate 1, and an L-shaped groove 21 is provided on the side where the two mounting rods 4 are close to each other, and a slider 22 is slidably connected to the inner wall of the L-shaped groove 21, and a protection mesh plate 7 is provided on the side where the two mounting rods 4 are close to each other, and the two sliders 22 are respectively fixed to the two sides of the protection mesh plate 7, and a push rod 6 is fixed on one side of the two mounting rods 4, and the push rod 6 is abutted against the bottom surface of the protection mesh plate 7, and the protection mesh plate 7 is located at the upper end of the monitoring alarm 2. When the monitoring alarm 2 is not working, the protection mesh plate 7 is vertically located between the two mounting rods 4. When monitoring is performed, the protection mesh plate 7 is pulled up to make the slider 22 slide to the upper end of the L-shaped groove 21, and the protection mesh plate 7 is flipped over, and the protection mesh plate 7 is limited by the push rod 6, so that the protection mesh plate 7 protects the upper end of the monitoring alarm 2 and reduces the collision of falling objects with the monitoring alarm 2.

[0025] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that a grip ring 13 is fixed on the side of the protective mesh 7 away from the mounting rod 4, and the grip ring 13 facilitates the movement of the protective mesh 7; two fixing rods 14 are fixed on one side of the connecting rod 12, and wrist rings 10 are fixed at the ends of the two fixing rods 14.

[0027] This scheme has the following working process: due to the different heights of the staff, the staff need to bend down to different degrees when moving the storage box, which brings inconvenience to the staff. When the monitoring positions are far apart, the work intensity of the staff will be increased. By pulling the pull rod 9, the movable rod 19 is driven to move up in the movable groove, so as to adjust the height of the pull rod 9 to adapt to the staff of different heights. Then, under the elastic force of the spring 16, the connecting rod 12 is pushed to move, so as to drive the insertion rod 18 to be inserted into the insertion hole 20 of the movable rod 19, so as to adjust the movable rod 19. 19 is used to limit the position, maintain the stability of the pull rod 9, and then the monitoring alarm 2 is pushed to move by the roller 3. The shoulder strap 5 can also be used to facilitate the staff to carry it on their backs, thereby providing more moving methods and improving the portability of the monitoring alarm 2. When performing monitoring work, the protective mesh plate 7 is pulled up to make the slider 22 slide to the upper end of the L-shaped slide groove 21, and the protective mesh plate 7 is flipped over. The protective mesh plate 7 is limited by the support rod 6, so that the protective mesh plate 7 protects the upper end of the monitoring alarm 2 and reduces the impact of falling objects on the monitoring alarm 2.

[0028] According to the above working process, it can be known that: through the setting of the pull rod 9, the movable rod 19, the movable groove and the limiting mechanism, the function of adjusting the height of the pull rod 9 is realized, so as to adapt to staff members of different heights, and the movable rod 19 is limited to maintain the stability of the pull rod 9, and then the monitoring alarm 2 is pushed to move by the roller 3, wherein the shoulder strap 5 can also be used to facilitate the staff to carry the device on their backs, thereby providing more moving methods and improving the portability of the monitoring alarm 2. When performing monitoring work, the protective mesh plate 7 is pulled up to make the slider 22 slide to the upper end of the L-shaped slide groove 21, and the protective mesh plate 7 is flipped over. The protective mesh plate 7 is limited by the push rod 6, so that the protective mesh plate 7 protects the upper end of the monitoring alarm 2 and reduces the collision of falling objects with the monitoring alarm 2. The circular through hole 8 and the bracelet 10 facilitate the hanging of the L-shaped mounting plate 1, providing diversity for the placement of the device and adapting to more usage scenarios.
