The guide rail 9 and the slider 10 can drive the transmission plate 8 and the transmission rod 6 to move in translation, thereby driving the clamping member to move in translation. The structure is simple and the function is reliable.

In this embodiment, in order to ensure that the clamped pipes can be centered, and to avoid shaking of the pipes when the clamping rotating disk 2 rotates. The clamping member includes two oppositely arranged first clamping members 11 and two oppositely disposed second clamping members 12, and the first clamping member 11 is located on the side of the second clamping member 12. Below, rollers 5 are arranged at the ends of the two, and the two opposite rollers 5 cooperate to clamp the pipe material, so that the pipe material can be conveniently and reliably clamped and centered.

The power assembly includes an adjustment screw 14 , a bearing seat 13 and a pair of clip linkages 3 , wherein both ends of the adjustment screw 6 are mounted on the clamping rotating disk 2 through the bearing seat 13 , and threadedly engaged with the transmission rod 6 .
