After the adjustment is completed, the pull rod 102 is fixed by the fixing knob 103, and the pull rod 102 is controlled to pull the frame 1 to transport materials at the disaster site for rescue operations.

[0025] Further, shock absorbers 104 are fixedly installed at the front and rear ends on both the left and right sides of the vehicle frame 1. At one end of each of the two groups of shock absorbers 104 away from the vehicle frame 1, a protective plate 105 is fixedly installed. When transporting materials, the left and right sides of the vehicle frame 1 are protected by the protective plate 105, and the impact force is buffered by the shock absorbers 104 to prevent the vehicle frame 1 from being damaged by impact.

[0026] Then, at the four corners at the bottom of each of the two groups of adjusting frames 3, rollers 301 are rotatably connected. On the opposite sides of the two groups of adjusting frames 3, they are both threadedly connected to the bidirectional screw 4. The front and rear ends of the two groups of adjusting frames 3 are both slidably connected to the slide bar 5. By rotating the bidirectional screw 4, with the assistance of the rolling of the rollers 301 and the connection of the slide bar 5, the distance between the two groups of adjusting frames 3 can be adjusted according to the size of the transported materials, so that the distance between the fixing plates 6 can be adjusted. Furthermore, the materials are clamped and limited by the fixing plates 6 to prevent the materials from shaking during transportation. At the same time, the outside of the materials can be protected to avoid damage during transportation, further improving the rescue efficiency.

According to the different heights of the materials, the extension plate 7 can be extended from the inside of the fixing plate 6 through the operating rod 701. After the extension plate 7 is extended, the fixing sleeve 703 is tightened for fixation. The extension plate 7 is used to limit and protect the outside of the materials, further improving the applicability of the rescue cart.

[0029] Finally, the pallet 8 is composed of two groups of connecting plates 801. One end of each group of connecting plates 801 away from each other is fixedly connected to the vehicle frame 1 by screws. The ends of the two groups of connecting plates 801 close to each other are inserted. Sliding grooves 802 adapted to the fixing plate 6 are provided inside the two groups of connecting plates 801. When transporting materials, after the joints of the two groups of connecting plates 801 are inserted, they are fixedly installed on the top of the vehicle frame 1 by screws. The pallet 8 composed of the two groups of connecting plates 801 holds the materials, and at the same time, the back of the materials is limited by the baffle 9, so as to ensure the positioning effect of the materials and avoid the problem of the materials shaking.

[0030] In this embodiment, the implementation scenario is specifically as follows: When transporting materials at the disaster site, first pull the pull rod 403 to release the fixation of the fixed gear block 404 on the fixed gear 402, and drive the bidirectional screw rod 4 to rotate by the crank 401. With the auxiliary rolling of the rollers 301 and the connection of the sliding rod 5, the distance between the two groups of adjusting frames 3 can be adjusted according to the size of the transported materials, so as to adjust the distance between the fixing plates 6. Furthermore, the materials are clamped and limited by the fixing plates 6. The pallet 8 holds the materials and the baffle 9 limits the back of the materials to avoid the problem of the materials shaking during transportation. At the same time, the outside of the materials can be protected to avoid damage during transportation.
