Steel pipe cutting machine capable of cutting multiple steel pipes simultaneously

The invention discloses a steel pipe cutting machine capable of cutting multiple steel pipes simultaneously. The steel pipe cutting machine comprises a base. A support leg is fixedly connected to oneside of the base. A support plate is fixedly connected to one side of the support leg. A driving device is fixedly connected to the top of the support plate and is matched with a toothed bar. The toothed bar is fixedly connected to the top of an L-shaped support plate. One end of the L-shaped support plate is slidably connected with the inside of a first sliding groove through a first sliding device. Through matched use of a first electric telescopic rod, a movable plate, a fixed limiting plate, a fourth sliding groove, a second electric telescopic rod, a movable limiting plate and a through hole, the cutting machine can achieve the condition that the multiple steel pipes are cut simultaneously, the problem that during cutting of an existing cutting machine, only one steel pipe is cut alone is solved, the problem of too low cutting speed during cutting of a plurality of steel pipes is avoided, in this way, cutting time is saved, and the work progress is quickened.
