AI Technical Summary

Technical Problem

Existing clamping and release mechanisms on spacecraft have the problem of potential crushing of the contact surface during steel ball locking, resulting in unstable locking and inconvenient unlocking.

Method used

The locking and releasing device adopts a linkage type, including a base, a sliding sleeve, a puller, a split nut assembly, a linkage, and a tension spring. The rotation of the sliding sleeve drives the linkage to deflect, thereby achieving locking and unlocking, avoiding the problem of crushing of the contact surface due to the steel ball locking.

Benefits of technology

It achieves stable and reliable locking, can withstand large locking forces, and is easy to unlock. It has a compact structure and is suitable for unlocking and separating equipment in spacecraft.
