The mechanical positioning and locking device for the aircraft tool can effectively control the locking and unlocking states through the handle; meanwhile, the reset spring 3 of the handle and the stepped hole 102 of the locking sleeve 1 can effectively stabilize the locking state, so that the handle is prevented from loosening or retreating due to vibration or mistaken collision; the proximity sensing switch 110112 can realize effective feedback of the locking state, and has good practicability.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
