Electric transmission line repair pipe smoothing and crimping mechanism and use method thereof

The invention discloses a smoothing and crimping mechanism for a repair pipe of a power transmission line and a use method of the smoothing and crimping mechanism. The smoothing and crimping mechanism comprises a workbench, a guide rail, a first linear driving piece, a smoothing device and a crimping device, the smoothing device comprises a clamping assembly, a clamping block and a first rotation driving assembly. The clamping assembly is arranged on the guide rail in a sliding mode, and the movable end of the first linear driving piece is connected with the clamping assembly. The clamping block is rotatably arranged at the movable end of the clamping assembly, a clamping channel allowing the repairing pipe to penetrate through is formed in the clamping block and is parallel to the guide rail, and a horn mouth is formed in a channel opening of the clamping channel. The first rotation driving assembly is in transmission connection with the clamping block. The clamping block is controlled to rotate while drivin
