lantern ring; the main cylinder seat is arranged at the
tail part ofthe main rotating shaft; the reset spring is arranged on the main cylinder seat; the connecting fork is arranged on the main cylinder seat and extrudes the reset spring; the annular screw-in snap ring is arranged on the main cylinder seat and extrudes the connecting fork; the
handle is connected with the main rotating shaft; and the three detachable stretching assemblies are arranged between theconnecting fork and the main support, and each stretching
assembly comprises a long-strip-shaped first connecting piece, a rod-shaped second connecting piece, a door-shaped clamping support and a clamping sliding block. According to the double-wall corrugated
pipe cutter, due to the fact that the three stretching assemblies are adopted, effectively
cutting the inner wall of a pipe by blades can becarried out, notches are neat and attractive, the operation is easy, and the
