Claims

[Scope of utility model registration request]

In a device for holding and releasing a movable part from a fixed part of a drive mechanism for mounting an artificial satellite, a plurality of devices are provided at predetermined intervals on a surface of the fixed part facing the movable part,
a first support formed by a pair of leaf springs having locking pins or pin holes at the pair of open ends;
a second support provided in the movable part so as to be located between the pair of leaf springs, and having a pair of pin holes or lock pins that engage with the pair of lock pins or pin holes; It is provided at a position corresponding to the first support so as to be movable in the direction of the corresponding first support and in the opposite direction, and the open end portions of the pair of leaf springs are sandwiched from the outside. a pushing tool having a V-shaped claw; a spring that urges the pushing tool in a direction opposite to the direction of the first support; a pulley rotatably provided on each of the pushing tools; a cable stretched between the cables and maintaining the engaged state between the pair of lock pins and the pair of pin holes by the pusher; and a buckle that adjusts the tension of the cable between the pulleys;
A holding/release mechanism comprising a spring for absorbing thermal displacement provided in the middle of the cable and a means for cutting the cable, wherein the cable is provided with a ball for a stopper, and the fixed part is provided with a stopper for the cable. A holding/release mechanism characterized by:
