[0026] like Figure 4As shown, when the first vehicle body 1 is separated from the second vehicle body 2, the first vehicle body 1 and the second vehicle body 2 can be connected by a connecting plate 7, a plurality of first through holes 15 are provided on the upper portion of the first bearing plate 11, a plurality of second through holes 26 are provided on the upper portion of the second bearing plate 21, one end of the connecting plate 7 is connected to the first through holes 15 by bolts, and the other end of the connecting plate 7 is connected to the second through holes 26 by bolts. By replacing the length of the connecting plate 7, the distance between the first vehicle body 1 and the second vehicle body 2 can be adjusted, thereby achieving the length adjustment of the frame to meet the transportation of some longer equipment or instruments. By adjusting the distance between the first vehicle body 1 and the second vehicle body 2, not only can the transportation of equipment and instruments of various specifications and sizes be met, realizing the multi-purpose function of one vehicle, but also the space occupied by the utility model can be effectively reduced, making it convenient to store and carry.
[0027] Two first universal wheels 13 are provided at the lower part of the first bearing plate 11 away from the second bearing plate 21, and two first rollers 3 are provided at the lower part of the first bearing plate 11 close to the second bearing plate 21. The first rollers 3 are connected to the first bearing plate 11 through a swing arm 4. Specifically, a first connecting shaft 41 is provided at one end of the swing arm 4 and a convex shaft 42 is provided at the other end. The first connecting shaft 41 is rotatably connected to the first bearing plate 11, and the convex shaft 42 is connected to the first rollers 3 through a bearing. It can be seen that the first rollers 3 can roll along the convex shaft 42 and can also rotate in universal directions with the first connecting shaft 41 as the axis. By arranging the first universal wheels 13, the swing arm 4 and the first rollers 3, the four-wheel universal rotation function of the first vehicle body 1 can be realized, so that even if the first vehicle body 1 and the second vehicle body 2 are separated, the first vehicle body 1 can move normally.
[0028] Two second rollers 61 are provided at the lower part of the second carrying plate 21 near the first carrying plate 11, and the two second rollers 61 are connected by a second connecting shaft 6, and the second rollers 61 are connected to the second connecting shaft 6 by a bearing, and two second universal wheels 23 are provided at the lower part of the second carrying plate 21 away from the first carrying plate 11.

[0030] like Figure 5 As shown, when it is necessary to transport equipment or instruments that are long and heavy, the first vehicle body 1 and the second vehicle body 2 can be directly split into two independent vehicle bodies. The first vehicle body 1 and the second vehicle body 2 respectively carry the two ends of the equipment or instruments, and because the first universal wheel 13 and the second universal wheel 23 are provided, the steering function can be realized when carrying the equipment or instruments, thereby facilitating transportation.
[0031] like Figure 2 As shown, further, a convex plate 24 is provided at the lower part of the second bearing plate 21, and the second connecting shaft 6 passes through the convex plate 24. Specifically, when the first vehicle body 1 and the second vehicle body 2 abut against each other, the second roller 61 is located on the inner side of the first roller 3 and the first roller 3 is connected to the second roller 61 through the first handle bolt 5, and limiting grooves 62 are provided at both ends of the second connecting shaft 6, and the first handle bolt 5 can pass through the convex shaft 42 and be inserted into the limiting groove 62, and the first handle bolt 5 is threadedly connected to the convex shaft 42.
[0032] When the first vehicle body 1 and the second vehicle body 2 are in contact with each other, by screwing the first handle bolt 5, the end of the first handle bolt 5 is inserted into the limiting groove 62, which not only realizes the connection between the first vehicle body 1 and the second vehicle body 2, but also limits the first roller 3 to prevent the first roller 3 from rotating along the first connecting shaft 41, thereby improving the reliability of the structure.
[0033] Furthermore, a handle 27 is provided on the upper portion of the second frame 22. The handle 27 can facilitate the movement of the utility model.
