The memorial alloy sleeve (1005) is accommodated at the step of the shell (1004) step groove, and original state is bottom
The semi-enclosed tube-in-tube structure in portion, offers that promote end for the pin (1001) logical on the bottom surface contacted with step groove step
It crosses and its bottom end is limited in the aperture of the memorial alloy sleeve (1005) below, and the memorial alloy sleeve (1005)
Bottom opening expands after powered up so that the pin (1001) bottom end passes through；
The spring (1002) is placed in the shell (1004) step groove bottom, and one end is contacted with step groove bottom surface,
By the pin (1001) and described when the bottom surface end in contact of the other end and the pin (1001), the spring (1002) are initial
Memorial alloy sleeve (1005) is limited to compressive state jointly；
In the secure state, the memorial alloy promotional implement (10) is in original state to interrupter, and the bushing (1007) will
The steel ball (1203) is limited in the annular groove on the bolt (1201), i.e., the bolt (1201) of the described lock pin (12) this
When be inserted into the lock pin notch (105) rotor (1) be locked in safe condition；Interrupter is converted to from safe condition
When arm-to-arm, control system is powered to the memorial alloy promotional implement (10), and memorial alloy sleeve (1005) bottom is opened
The borehole enlargement in hole passes through the bottom end of the pin (1001), and the compressive state of the spring (1002) releases, and relies on
It restores elastic force and releases the pin (1001), so that the bushing (1007) is far from the steel ball (1203), the steel ball
(1203) it is detached from from annular groove, so that the bolt (1201) of the lock pin (12) is detached from the lock pin notch (105),
Release the locking to the rotor (1).
