When the staff needs to adjust the height of the device, first The two adjusting blocks 6 are driven to move toward or away from each other in the two sliding grooves 4 by the rotation of the two-way threaded rods 5. The movement of the adjusting blocks 6 drives the movement of the rotating blocks 7. At this time, because the support frame 8 is fixedly mounted inside the rotating block 7 by the mounting bolts 9, the movement of the rotating block 7 drives the support frame 8 to move axially. At this time, the rotating block 7 rotates inside the adjusting block 6, thereby realizing the adjustment of the height of the mounting plate 11. At the same time, when the subsequent staff needs to disassemble the support frame 8, the support frame 8 and the rotating block 7 can be separated by rotating the mounting bolts 9. The above structure improves the flexibility of the device, and it is convenient for the staff to adjust the installation height according to the actual use requirements, thereby increasing the application range of the device. At the same time, disassembling the support frame 8 also facilitates the storage of the device, which is convenient for the subsequent transportation and movement of the device.

The staff starts the first motor 12 to drive the left worm 14 to rotate. At this time, since the square rod 15 and the left worm 14 are fixedly connected, the rotation of the left worm 14 can drive the rotation of the square rod 15, and because the right worm 14 is slidably sleeved on the outside of the square rod 15, the rotation of the square rod 15 can drive the rotation of the right worm 14.

[0032] Working principle:

[0033] When the aircraft auxiliary cargo bridge support bracket is in use, the two bidirectional threaded rods 5 are rotated, and the rotation of the bidirectional threaded rods 5 drives the two adjusting blocks 6 to move toward or oppositely inside the two sliding grooves 4 respectively, and the movement of the adjusting blocks 6 drives the movement of the rotating block 7. At this time, because the support frame 8 is fixedly installed inside the rotating block 7 by the mounting bolts 9, the movement of the rotating block 7 will drive the support frame 8 to move axially. At this time, the rotating block 7 will rotate inside the adjusting block 6, thereby realizing the adjustment of the height of the mounting plate 11. At the same time, when the subsequent staff needs to disassemble the support frame 8, the support frame 8 and the rotating block 7 can be separated by rotating the mounting bolts 9.
