The invention belongs to the technical field of spaceflight, and discloses a pressing and releasing device and satellite equipment. The pressing and releasing device comprises a fusing module, a supporting module and a rope ring, the fusing module comprises a first connecting piece and a fusing piece, and the first connecting piece comprises two first rope winding parts and two rope penetrating holes; the supporting module comprises a support and two second connecting pieces connected with the support, and the two second connecting pieces correspond to the two rope penetrating holes in a one-to-one mode. The rope ring abuts against the fusing piece, in the direction close to the support, one end of the rope ring penetrates through one rope penetrating hole in the direction close to the support, is connected with the corresponding second connecting piece in a winding mode and is fixedly connected with one first rope winding part in a hanging mode, and the other end of the rope ring penetrates through the other rope penetrating hole in the direction close to the support. And the corresponding second connecting piece is wound and fixed with the other first rope winding part in a hanging manner. The device solves the problems that the compression function is easy to lose efficacy under complex working conditions due to insufficient compression force of the rope ring, and the load compression and unfolding reliability of spacecrafts such as satellite equipment is influenced.
