[0048] The following is further introduced in conjunction with the specific working method, as described below: Specifically, when the civil aviation maintenance support device is working / in use: the first electric rod 203 is started, and the first electric rod 203 pushes the moving tooth plate 202 to move upward, and when the moving tooth plate 202 moves to a suitable position, the operation of the first electric rod 203 is stopped;

[0049] Start the hydraulic cylinder, one end of the hydraulic cylinder pushes the scissor telescopic assembly to move upward, pushes the lifting plate 4 to move upward, the rotating gear 206 on one side of the lifting plate 4 engages with the moving tooth plate 202 to rotate, the rotating gear 206 drives the first cone wheels 208 on both sides to rotate, the first cone wheel 208 engages with the second cone wheel 209 to rotate, the second cone wheel 209 drives the rotating rod 210 to rotate on one side of the lifting plate 4, the rotating rod 210 drives the second electric rod 211 and the clamping member 220 to rotate, the second electric rod 211 drives the moving member 306 to move inside the second tooth plate 305 through the connecting member 310, the first moving rod 308 and the second moving rod 309;

[0050] When the second electric rod 211 on one side is squeezed by external force during rotation, the rotating rod 210 continues to rotate, and the clamping member 220 connected to one side of the second electric rod 211 is disengaged from one side of the second electric rod 211 by the squeezing force transmitted by the second electric rod 211, so that the second electric rod 211 squeezed by external force no longer rotates with the rotating rod 210, the lifting plate 4 continues to move upward, and the second electric rod 211 on the other side continues to rotate. The infrared sensor 205 can detect the position of the guardrail 11. When the receiver on one side of the guardrail 11 rises to be parallel to the infrared sensor 205, the infrared sensor 205 stops the hydraulic cylinder through the control device 15, so that the position of the lifting plate 4 no longer moves upward, ensuring that the staff will not hit the aircraft when the lifting plate 4 rises, avoiding unnecessary injuries;

[0051] When the clamping member 220 is disengaged from the second electric rod 211, the clamping member 220 is forced to move inside the rotating ring 219, pushing the contact plate 218 to squeeze the compression spring 217 and the squeezing switch 216, and the squeezing switch 216 converts the squeezing force into an electrical signal and transmits it to the controller 5. The controller 5 locates the current position and controls the second telescopic rod 307 on the other side to start. The second telescopic rod 307 fixes the second toothed plate 305, and the second electric rod 211 on the other side continues to rotate with the rotating rod 210.
