The second electrically controlled telescopic rod can be extended and retracted to change the position of the collar, so that the contact limiting roller can follow the collar for adjustment. At this time, the contact limiting roller can contact the gas cylinder to limit the top of the gas cylinder, so that the gas cylinder can be better protected during processing. The top position limiting can be adjusted according to the needs of use, and the connection position of the contact limiting roller and the gas cylinder can be changed, thereby realizing a flexible limiting function. In addition, this structure adopts the upper limit, which is the first limiting structure for top limiting.

[0017] Second, the present invention facilitates position adjustment of the first docking support component and the second docking support component through the setting of the supporting component, the third stepping motor controls the rotation of the screw rod to change the position of the first docking support component and the second docking support component, and the threads on the screw rod are symmetrically and reversely set, which can make the first docking support component and the second docking support component move in opposite directions, thereby performing docking processing of the gas tank, and the electric-controlled telescopic seat changes the position of the fifth electric-controlled telescopic rod, and the fifth electric-controlled telescopic rod changes the position of the limiting wheel, which can make the limiting wheel contact with the inner wall of the gas tank to limit the inner wall of the gas tank. At the same time, the extension and contraction of the third electric-controlled telescopic rod changes the position of the rotating hinge block, so that the upper end rod body of the rotating hinge block slides on the track slot frame, thereby supporting the movable frame, so that the movable frame can adjust the angle on the support end frame through the first hinge rod. At this time, the second stepping motor supports both sides of the gas tank, thereby performing multi-angle gas tank limiting work, which is convenient for the welding and docking of the gas tank. The cam is connected with the guide rail by the shaft, and the upper end of the cam is connected with the track groove frame by the shaft, and the cam can slide on the track groove frame, so that the swing of the cam can support the movable frame to move around the first hinge rod, and the movable frame can rotate and adjust with the support end frame at this time, thereby driving the support platform, the second stepper motor and the rotating wheel to adjust the position. At this time, the rotating wheel can squeeze and limit the gas tank, and the support platform, the second stepper motor and the rotating wheel are provided with two, which can be docked for special-shaped gas tanks. At this time, the first adjustment support mechanism and the second adjustment support mechanism move symmetrically in opposite directions, thereby gathering the two sides to the center position, and limiting the special-shaped gas tank in the center.
