Flaring mechanism and flaring device

The invention provides a flaring mechanism and a flaring device.The flaring mechanism comprises a clamping assembly and a moving assembly, the clamping assembly comprises a clamping component and a clamping driving part, the clamping component comprises a first clamping piece and a second clamping piece, and the clamping driving part can drive the first clamping piece and the second clamping piece to get close to each other or get away from each other; the clamping component is switched between an opening state in which the distance between the first clamping piece and the second clamping piece is larger than a preset value and a clamping state in which the first clamping piece and the second clamping piece jointly clamp the flat wire, and the preset value is larger than the thickness of the flat wire; the moving assembly comprises a moving driving piece, and the moving driving piece can drive the clamping assembly to move in the flaring direction when the clamping component is in the clamping state.
