[0002] Galvanized steel pipe refers to a steel pipe with a layer of zinc plated on the surface. Its main function is to improve the corrosion resistance of the steel pipe to extend its service life. The zinc layer can form a protective film on the surface of the steel pipe, which effectively blocks the erosion of the external environment such as air and moisture. Galvanized steel pipe has the advantages of good corrosion resistance, high strength and relatively low price. It can adapt to a variety of environmental conditions, reduce rust and damage, and can be used in occasions with certain pressure and load. It has certain economy. Galvanized steel pipe will be cut into suitable lengths according to actual applications, so a cutting device for galvanized steel pipe processing will be used.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the reciprocating threaded rod is driven to rotate by starting the motor, so that the threaded block drives the L-shaped rod to move, causing the piston to reciprocate. Therefore, the air inlet will suck in the outside air and then spray it out from the air outlet pipe. The two cylinders are started to move the cutting wheel downward for switching.

Alternatively, the electric push rod is started to pull the pressure plate to press the top of the steel pipe, forming a rigid clamp, making the clamping more stable. The two modes can be freely selected. BRIEF DESCRIPTION OF THE DRAWINGS
