[0065] Further, in this embodiment, a rolling pulley 2023 is provided between the main hanging basket 206 and the stretching hanging basket 202.

[0070] Furthermore, in this embodiment, crawlers 4 are provided on both sides of the vehicle body 1. The crawlers 4 can effectively increase the contact area between the vehicle body 1 and the ground, which is conducive to ensuring that the vehicle body 1 can remain in a stable state during operation.

[0072] Furthermore, in this embodiment, each support leg 5 includes a horizontal support arm and a vertical support arm connected vertically; the horizontal support arm and the vertical support arm are both retractable adjustment rods. By retracting the horizontal support arm in the horizontal direction and the vertical support arm in the vertical direction, the actual support position of the entire support leg 5 can be adjusted, so that the support leg 5 can better contact and abut against different ground surfaces, making it convenient to fix the vehicle body 1 on different ground surfaces, effectively increasing the operation scenarios of the device.
