[0022] Furthermore, in this embodiment, a sliding swivel base 8 is also provided on the base 1, and the sliding swivel base 8 is connected to the base 1 through a sliding telescopic oil cylinder 9. By designing and adding a forward and backward sliding function on the basis of the original lifting support structure, the problem of the small distance between the front end of the support and the gun head can be effectively solved, which improves the work efficiency and ensures the safe working space of the workers. The sliding swivel base 8 is connected to the telescopic mechanism 2 through a folding oil cylinder 10. The telescopic mechanism 2 includes a primary telescopic arm 21, a secondary telescopic arm 22 and a tertiary telescopic arm 23.
