Both ends of the support plate 222 are connected to the support column 221, and the support plate 222 is also connected to the fixed component 23.

[0034] In some embodiments, the fixing component 23 is used to fix the hydraulic cylinder for surface treatment, and includes: a movable plate 231, a fixed plate 232 connected to the movable plate 231, a fixed seat 233 disposed on the fixed plate 232, a pressure plate 234 adapted to the fixed seat 233, and a second hydraulic cylinder 235 connected to the pressure plate 234.
