And a pipe limiting mechanism is arranged on the rack and between the pipe fixing mechanism and the pipe clamping rotating mechanism.

After the structure is adopted, the pipe fixing mechanism is used for fixing the pipe when the fine feeding mechanism retreats; the pipe limiting mechanism is used for limiting the feeding amount of the pipe when the coarse feeding mechanism performs coarse feeding. The rough feeding mechanism realizes the forward amount (non-control processing feed amount) of the pipe during rough feeding; the pipe clamping and rotating mechanism is used for clamping the pipe and effectively controlling the rotation angle of the pipe; the precise feeding mechanism controls the precise feeding amount of the pipe (and drives the pipe clamping rotating mechanism to move forwards and backwards) through the meshing motion of the gear on the rack.
