Specifically, two adjustment panels 201 are provided at the second end of the first side panel 20 in the extension direction, and each adjustment panel 201 is formed with a plurality of screw holes; correspondingly, the first extension panel 21 is formed into a bent structure, and is also formed with an oblong through hole. When the first extension panel 21 is assembled with the first side panel 20, the first extension panel 21 is located between the two adjustment panels 201. After adjusting the relative positions of the two, corresponding studs can be provided in the screw holes and the through holes.

[0042] Similar to the first side panel assembly, the second side panel assembly further includes a second extension panel 31 detachably connected to a second end of the second side panel 30 in an extension direction. The second extension panel 31 can also be telescopic relative to the second side panel 30 .

[0043] In addition, the main board is also provided with a suspension ball head 14 for connecting to the tractor pull rod, and the ends of the first extension plate 21 and the second extension plate 31 that are away from each other are also provided with width indicator lights 16 to serve as a warning.
