[0026] The outer surface of the articulated column 102 is movably connected to the articulated cylinder 103, the bottom of the articulated sleeve 101 is fixedly connected to the special-shaped support plate 104, the interior of the articulated cylinder 103 is connected to the ball bearing 105, and the inner ring of the ball bearing 105 is fixedly connected to the connecting column 106, so that the articulated sleeve 101 is connected to the articulated cylinder 103 through the articulated column 102, and the rotation of the articulated cylinder 103 is further limited by the articulated column 102, and the connecting column 106 is further supported and limited by the ball bearing 105 inside the articulated sleeve 101, so that the connecting column 106 rotates inside the articulated sleeve 101.

[0027] The lubrication unit includes a lubricating oil tank 301, a connecting pipe 302, an oil pump 303, a transport pipe 304, an oil delivery ring 305, and an oil delivery nozzle 306. The lubricating oil tank 301 is installed below the hinge sleeve 101, the connecting pipe 302 is installed on the lubricating oil tank 301 and is fixedly connected to the side of the lubricating oil tank 301, the oil delivery pump 303 is fixedly connected to one end of the connecting pipe 302 away from the lubricating oil tank 301, the transport pipe 304 is connected to the other end of the oil pump 303, and the oil delivery ring 305 is connected to the transport pipe 304 away from the oil pump 303. At one end, an oil delivery nozzle 306 is fixedly connected above the outer surface of the oil delivery ring 305, so that by starting the oil delivery pump 303, the oil delivery pump 303 transports the lubricating oil inside the lubricating oil tank 301 to the inside of the delivery pipe 304 through the connecting pipe 302, and further transports it to the oil delivery ring 305 through the delivery pipe 304, and further transports it to the oil delivery nozzle 306 through the oil delivery ring 305, and sprays it on the outer surface of the ball bearing 105 through the oil delivery nozzle 306, so as to achieve a better lubrication effect, thereby making turning, rotation, etc. smoother.

[0028] The support unit includes a fixed plate 201, a rotating column 202, a movable plate 1 203, a hydraulic rod 204, a movable plate 205, and a connecting sleeve 206. The fixed plate 201 is fixedly connected to the top of the special-shaped support plate 104, the rotating column 202 is movably connected to the inside of the fixed plate 201, the movable plate 1 203 is fixedly connected to the outer surface of the rotating column 202, the hydraulic rod 204 is fixedly connected to the top of the movable plate 1 203, the connecting sleeve 206 is fixedly connected to the outer surface of the hinge cylinder 103, and the movable plate 205 is movably connected to the side of the connecting sleeve 206.
