[0032] Specifically, in the use of pneumatic lifting set for vehicle rescue, the air source device 5 provides the necessary power for the crane 1, after starting the crane 1, the lifting rod 11 starts to work immediately, when it is necessary to fix or adjust the working position, by rotating the fixed circular plate 16, the bidirectional threaded rod 15 rotates, because the bidirectional threaded rod 15 is connected with the clamping block 22 at both ends through threads, during the rotation process, the clamping block 22 moves along the axial direction of the bidirectional threaded rod 15, thereby adjusting the distance between the two clamping blocks 22, at the same time, the sliding block 23 can slide in the clamping groove 21 according to the actual demand, to adapt to different rescue scenes, to ensure the stable clamping and support of the rescue target, so as to complete the lifting operation of vehicle rescue.

[0038] When it is necessary to expand the contact area of the air source device 5 with the ground, the rotating disc 204 is rotated to drive the fixedly connected connecting rod 202 to rotate, since the rear side of the connecting rod 202 is fixedly connected with the front side of the expansion plate 201, the rotation of the connecting rod 202 drives the expansion plate 201 to rotate around the rotating connection point at the bottom of the air source device 5, realizing outward expansion, the adjacent rotating shaft 203 plays a role in assisting rotation in the expansion process of the expansion plate 201, ensuring stable rotation of the expansion plate 201, after the two expansion plates 201 are expanded, the contact area of the air source device 5 with the ground is increased, and the stability is improved, when the expansion mechanism 2 is adjusted in place, the clamping rod 206 can play a fixing role, and the first protective sleeve 207 on the outer side can protect the clamping rod 206 from being damaged by external factors.
