The invention relates to the technical field of aerospace equipment, in particular to a hot melting type pressing and releasing device which comprises a bottom plate and a PE binding wire, and the bottom plate is provided with a releasing device and a pressing device for fixing a part to be unfolded; the pressing device comprises a supporting seat arranged on the bottom plate, a fixing shaft is arranged in the supporting seat in a penetrating mode, a connecting block and a threaded column are sequentially arranged above the supporting seat, a fishbone is arranged in the threaded column, an upper nut is arranged above the fishbone, and a lower nut is arranged below the fishbone. The releasing device comprises a single-shaft base, a moving shaft is arranged in the single-shaft base in a penetrating mode, a blocking piece is arranged at one end of the moving shaft, a spring is arranged between the blocking piece and the single-shaft base, a fixing mechanism is arranged at the other end of the moving shaft, and a resistance wire is arranged in the fixing mechanism. The PE binding wire wraps the resistance wire, the fishbone and the fixing shaft. Compared with an initiating explosive device unlocking device, the initiating explosive device unlocking device is simple in structure, high in assemblability, low in cost, high in reliability and capable of achieving low-impact, low-pollution and reusable unlocking.
