[0002] Power pipes are pipes used to protect wires and cables. Common materials include PE (modified polyethylene), PVC (polyvinyl chloride), MPP (modified polypropylene), etc. Power pipes need to be cut according to different usage scenarios during production and use.

[0003] Conventional cutting devices usually need to repeatedly disassemble and assemble the clamped workpieces at both ends of the cutting position when switching the cutting position, resulting in low cutting efficiency; and during the cutting process of the power pipe, the power pipe is hollow inside, causing the cut power pipe to bend inward, affecting the performance of the power pipe.

[0004] Therefore, it is necessary to provide an electric power pipe cutting device to solve the problems raised in the above background technology. Utility Model Content

[0008] As a preferred technical solution of the utility model, the clamping assembly includes: a clamping cylinder, rotatably arranged at the extension end of the support platform; an inner support cylinder, fixed in the clamping cylinder, an inner protrusion circumferentially fixed on the outer wall of the inner support cylinder; and an external clamper, circumferentially fixed on the inner wall of the clamping cylinder.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The motor drives the long screw to rotate, so that the first foot can reach any position inside the power tube. At the same time, the two adjustable telescopic instruments are adjusted to make the rollers close to the inner wall of the power tube, so that the two ends can be quickly fixed and limited while changing the cutting position, and there is no need to repeatedly disassemble and assemble the clamped workpiece, thereby improving the cutting efficiency of the power tube;
