Clamping device for metal pipeline cutting

The utility model provides a clamping device for metal pipeline cutting. The clamping device for metal pipeline cutting comprises a mounting plate lower supporting assembly fixedly connected to the top of the mounting plate, and a clamping plate lower supporting assembly fixedly connected to the top of the mounting plate. The side plate is fixedly connected to one side of the top of the mounting plate; the two sliding rails are fixedly connected to the front side and the rear side of the top of one side of the side plate correspondingly. According to the clamping device for metal pipeline cutting, metal pipeline pieces with different lengths can be clamped after the lower supporting assembly and the pressing assembly are matched, so that the application range of the device is effectively widened, the pipeline can be effectively and stably clamped, the pipeline is prevented from moving in the cutting process, and the working efficiency of the device is improved. And in addition, dust and sweeps generated durin
