[0039] Specifically, when the servo motor 7 is started, the steel cable 9 will be retracted and extended under the guidance of the left turntable 8, thereby controlling the lifting and lowering of the connecting plate 10 to ensure the precise movement of the mechanical claw device 12 in the vertical direction. No matter what the shape of the roof is, it can ensure that it can accurately reach the target position. The two electric telescopic rods 11 provide the mechanical claw device 12 with height adjustment capability. The telescopic action can change the vertical position of the mechanical claw device 12 so that it can adapt to roof structures of different shapes. The start-up of the cylinder 14 brings the function of angle adjustment to the device. The push-pull action of the cylinder will drive the hollow plate 6 to change the angle through the turntable 5. This design enables the suspended ceiling device to flexibly cope with sloping or curved roofs. The design of the hollow plate 6 not only saves materials, but also ensures the lightness and ease of operation of the equipment.

[0041] Specifically, the left side of the slider 15 is slidably connected to the slide groove 16, so that the stability of the lifting and lowering of the lifting plate 4 and the hollow plate 6 is improved, the support plate 20 and the support column 21 make the device more stable during operation, and the protective cover 19 can protect the connection of the steel cable 9.

[0042] Reference Figure 1, Figure 3 and Figure 4 The negative pressure mechanism 2 includes an extraction fan 201, the bottom wall of the extraction fan 201 is fixedly connected to the top wall of the vertical shell 1, the extraction end of the extraction fan 201 is connected to an extraction pipe 202, the bottom end of the extraction pipe 202 is connected to an annular pipe 203, the top wall of the annular pipe 203 is equidistantly connected to a plurality of connecting pipes 204, the bottom end of the connecting pipe 204 is connected to the mechanical claw device 12, a plurality of through-slot shells 205 are fixedly installed inside the mechanical claw device 12, and a filter plate 206 is fixedly connected to one side of the through-slot shell 205;

[0043] Specifically, after the extraction fan 201 is started, a strong airflow will be generated through the extraction pipe 202. Under the guidance of the annular pipe 203 and the connecting pipe 204, the airflow is guided to the through-slot shell 205. The through-slot shell 205 can effectively guide and concentrate the airflow. When the airflow passes through, a significant negative pressure phenomenon will be generated in the shell. Since the through-slot shell 205 is installed inside the mechanical claw device 12, the negative pressure in the shell will directly act on the contact surface, forming an inward pulling force. Under the action of this force, even if slight external force interference is encountered during the lifting process, the mechanical claw device can maintain a stable connection with the roof structure, thereby preventing safety hazards caused by unstable connection.

[0044] Reference Figure 1 , Figure 2 and Figure 4 A rubber ring 207 is fixedly installed at the bottom end of the outer wall of the extraction tube 202, and the outer wall of the rubber ring 207 is fixedly connected to the top wall of the annular tube 203; a control switch 17 is fixedly connected to the top of the front side of the vertical shell 1, and the control switch 17 is electrically connected to the hydraulic rod 3, the servo motor 7, the cylinder 14 and the extraction fan 201 respectively; a protective cover 18 is provided at the left end of the front side of the vertical shell 1, and the right side of the protective cover 18 is rotatably connected to the left side of the control switch 17 through a hinge;

[0045] Specifically, the rubber ring 207 can increase the service life of the connection of the extraction pipe 202 and reduce wear. The control switch 17 electrically connected to the hydraulic rod 3, the servo motor 7, the cylinder 14 and the extraction fan 201 respectively can open and close the device. The protective cover 18 can protect the control switch 17 and prevent accidental touch.

[0046] Working principle: When starting to use, by starting the servo motor 7, the steel cable 9 completes the lifting and lowering of the connecting plate 10 under the rotation of the left rotating wheel 8, and then by starting the two electric telescopic rods 11, the mechanical claw device 12 can grab and fix the roofs of different shapes and structures, thereby improving the connection effect when the ceiling is suspended. By starting the cylinder 14, the hollow plate 6 is adjusted in angle under the action of the rotating leaf 5, which improves the flexibility of the ceiling and avoids the situation where the special-shaped roof structure cannot be stably positioned well. And by starting the extraction fan 201, under the connection between the annular pipe 203 and the connecting pipe 204, the airflow extracted by the extraction pipe 202 causes the through-groove shell 205 to generate negative pressure, so that after the contact surface between the mechanical claw device 12 and the roof structure is fixed, a negative pressure effect can be formed, which improves the fixing effect during the ceiling hoisting work, reduces the situation of unstable connection, and improves work efficiency.
