Especially in long-term space missions, it can effectively reduce accidental damage caused by debris collision.

[0014] (3) The present invention sets an anti-loosening device to make the bidirectional motor, threaded rod 1, spacing nut, chuck, placement plate, and fixing nut cooperate. The bidirectional motor is started, and the rotation of the output shaft of the bidirectional motor drives the rotation of the threaded rod 1, and the rotation of the threaded rod 1 drives the movement of the spacing nut, thereby clamping the chuck, so that the chuck is clamped between the placement plate and the spacing nut.

It does not rely on complex and vulnerable components, increases the reliability of the system, reduces the risk of mechanical failure, and has stronger adaptability. In particular, in a vacuum, extreme temperature or radiation environment, the device can work more stably and is not easily affected by the space environment. It provides a smooth and adjustable unlocking process. Compared with the traditional mechanical clamping method, the device can achieve softer and more precise control during the opening process, thereby avoiding sudden vibration or irregular unlocking, reducing interference with other systems, and improving operational safety.

A circular hole 74 is opened on the top of the chuck 71 to pass through the threaded rod 53. Through the arrangement of the above structure, precise control is achieved. Control and positioning can reduce the risk of release failure or loosening due to inaccurate mechanical card connection, and can provide more stable and precise locking and unlocking actions. It does not rely on complex and vulnerable parts, increases the reliability of the system, reduces the risk of mechanical failure, and has stronger adaptability. Especially in vacuum, extreme temperature or radiation environment, the device can work more stably and is not easily affected by the space environment. It provides a smooth and adjustable unlocking process. Compared with the traditional mechanical card connection method, the device can achieve softer and more precise control during the opening process, thereby avoiding sudden vibration or irregular unlocking, reducing interference with other systems, and improving operational safety.

[0034] When in use, the bidirectional motor 52 is started, and the rotation of the output shaft of the bidirectional motor 52 drives the rotation of the threaded rod 53, and the rotation of the threaded rod 53 drives the movement of the spacing nut 72, thereby clamping the chuck 71, so that the chuck 71 is clamped between the placement plate 51 and the spacing nut 72, and the rotation of the threaded rod 53 drives the movement of the fixing nut 73, thereby replacing the clamping relationship of the chuck 71, achieving precise control and positioning, and reducing the risk of release failure or loosening due to inaccurate mechanical clamping. It can provide more stable and precise locking and unlocking actions, does not rely on complex and vulnerable components, increases the reliability of the system, reduces the risk of mechanical failure, and has stronger adaptability. Especially in a vacuum, extreme temperature or radiation environment, the device can work more stably, is not easily affected by the space environment, and provides a smooth and adjustable unlocking process.
