[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, this utility model comprises a drive motor, a rotating shaft, lead screws, a transmission belt, a moving plate, and a painting device. The painting device is clamped on the side wall of the moving plate. When painting a steel pipe, the operator directly fixes the steel pipe to the outside of the rotating shaft, positioning the steel pipe between the spray nozzles of the two painting devices. The operator starts the painting device, and simultaneously, the drive motor is started by an external power source, causing the rotating shaft to rotate. The rotating shaft, through the transmission belt, drives the lead screws on both sides to rotate, which in turn moves the moving plate. This allows the painting device to move and paint the rotating steel pipe. The movement speed is stable, the painting is uniform, the overall tool structure is simple, the operation is convenient, and the cost of use is low.

[0013] Furthermore, through the first and second support components, which are fixed to the outer sides of both ends of the rotating shaft, the support components consist of a spring, a support plate, and an inclined guide plate. When fitting the steel pipe, the end of the steel pipe is moved towards the inclined guide plate until the steel pipe is fitted onto the outer side of the support plate. The support plate is supported by the spring, thus achieving the support and positioning of the steel pipe. After the steel pipe is fully installed, the two support components support the inner wall of the steel pipe at two points respectively, providing stable support. Moreover, the support is from the inside and does not affect the painting of the steel pipe. At the same time, through elastic support, the support range can be automatically adjusted for steel pipes of different sizes, making it highly practical. Attached Figure Description
