A method for using a convenient cutting device for electric power pipelines in electric power construction, characterized in that: The convenient cutting device for electric power pipelines for electric power construction according to any one of claims 1 to 9 comprises the following steps: Step 1: first, according to the diameter of the pipe body (52), the pipe body (52) is placed in the position of the first clamping curved plate (18) at the corresponding position, and the first cylinder (6) is started to drive the first adjustment block (9) to move, so that the first inclined surface (10) of the first adjustment block (9) contacts the second inclined surface (17) of the second adjustment block (16), and the second adjustment block (16) is driven to move in the direction of the first clamping groove (12) and stretch the first spring (15), so that the first clamping curved plate (18) contacts the side wall of the pipe body (52), and the pipe bodies (52) of different diameters are clamped to facilitate cutting operations; Step 2: By rotating the adjusting protrusion (29) on the adjusting knob (28), the position of the second connecting plate (25) is adjusted in the direction of the threaded rod (27), and then the position of the movable plate (24) is adjusted, so that the position of the cutting motor (2) can be adjusted, and then the length of the pipe body (52) cut by the cutting blade (3) can be adjusted; Step 3: The bidirectional motor (34) rotates to drive the first gear to rotate, and then drives the first gear teeth (36) to mesh with the second gear teeth (38) to drive the rotating ring (37), and drives the cutting motor (2) connected thereto to rotate, so as to drive the cutting blade (3) to perform a circular cutting operation. The setting of the second cylinder (42) enables the cutting blade (3) to cut pipe bodies (52) of different diameters. The bidirectional motor (34) rotates to drive the reciprocating screw rod (48) to rotate, and then drives the reciprocating slider (50) to move back and forth. Under the elastic force of the third spring (46), the third clamping curved plate (47) clamps the pipe bodies (52) of different diameters. After the pipe bodies (52) are cut, the unused pipe bodies (52) that can be cut can be transported to facilitate the next step of processing.
