The lifting screw rod 12 is driven to rotate by rotating the crank 15, so that the lifting screw rod 12 drives the support plate 3 slidably connected to the upper end of the base column 2 to be lifted and lowered, thereby enabling the support plate 3 to support steel pipes of different radii, and the rollers 13 arranged on the upper side of the support plate 3 can reduce the friction between the steel pipe and the support plate 3 when the steel pipe rotates.

[0024] like Figure 3 and Figure 4 As shown, the clamping assembly includes a slide groove 8 corresponding to the fixed plate 7 opened on the clamping disk 19, the fixed plate 7 is slidably connected in the slide groove 8, and a clamping screw 14 is rotatably connected in the slide groove 8, and the clamping screw 14 is threadedly connected to the fixed plate 7 at the same time, and the clamping screw 14 is provided with a driving assembly to drive, and the driving assembly includes a bevel gear 16 fixedly connected to the outer end of the clamping screw 14, and the bevel gear 16 is also meshed with a conical toothed disk 17, and the center of the mounting plate 11 on one side close to the clamping disk 19 is fixedly connected to a clamping motor 18, and the conical toothed disk 17 is coaxially fixed with the output end of the clamping motor 18.
