Pressing and loading device of spacecraft pressing and releasing mechanism

The invention provides a pressing and loading device of a spacecraft pressing and releasing mechanism, which comprises a bracket, hooks and a rotating shaft, the upper part of the bracket is in limiting connection with the rotating shaft, the lower part of the rotating shaft is connected to a first pull rod through a tension sensor, two ends of the lower part of the first pull rod are symmetrically provided with two second pull rods, and two ends of the lower part of each second pull rod are symmetrically provided with two hooks. A first limiting block and a second limiting block are arranged at the bottom of the support, the first limiting block and the second limiting block limit the four drag hooks, and the four drag hooks provide pulling force for the W-shaped pressing belt. The pressing and loading device of the spacecraft pressing and releasing mechanism is compact in structure and small in operation space, tension is decomposed step by step through the seesaw principle, stress is uniform in the loading
