Fastening lock assembly for wings

In the wing plate locker, rotating the rotor produces the backward linear translation of slipform; erecting and rotating the locking arm makes the pressing part of the locking arm contact to the bearing part of the fixed frame; the bearing balls embedded into the ring groove of the fixed body and the rotor checks the rotor from separating from the fixed body; and the spring makes the locking arm suppressed. The back part of the slipform is constituted by the wall with back opening in the closed hollow part. The outer size of the operating handle is the same as the diameter length of the frontdisc in the fixed body.
