The invention discloses a spool lifting clamp with a self-locking function. The spool lifting clamp comprises a connecting plate, clamping jaws and a pressing plate. The clamping jaws are rotationally connected to the two ends of the connecting plate, and a guide hole is formed in the middle of the connecting plate. A guide shaft is arranged in the middle of the pressing plate, the guide shaft penetrates through the guide hole and can move along the guide hole, a pressure spring sleeves the guide shaft, and the two clamping jaws are movably connected with the two ends of the pressing plate separately. When the pressure spring is compressed, the distance between the connecting plate and the pressing plate is shortened to enable the two clamping jaws to be loosened, and when the pressure spring restores, the distance between the connecting plate and the pressing plate is increased to enable the two clamping jaws to be clamped. According to the lifting clamp, lifting is convenient, self-locking can be achieved after lifting, safety is high, and manpower is saved.
