The invention provides a bending loading swing head device. The bending loading swing head device is used for a flexible pipe cable fatigue test and comprises a swing head fixing support, a main plate, a tower, an end fixing plate and an end connector which are connected in sequence. The end part fixing plate and the end part joint are used for fixing the vertical pipe terminal to be tested; the tower frame is fixed on the main plate, and the length of the tower frame can be adjusted to adapt to stand pipe test pieces with different sizes and different screw pitches; a fixed bearing of the swing head fixing support is supported by an external supporting frame, and the whole bending loading swing head device can rotate around the axis of the fixed bearing. The length of the tower can be flexibly adjusted according to the test piece, limitation of the size and the screw pitch of the stand pipe test piece is avoided, the universality is high, and the problems that due to the fact that an existing swing head is n
