In the aerospace field, different carried objects need to be accommodated in the launcher, moving parts of some carried objects can drive the carried objects to execute a series of preset actions, and some carried objects are dangerous and need to be strictly controlled to be in a preset safety state. If the transmitter transmission fails, the motion piece receives external factor influence, then can't guarantee that the carried thing is in predetermineeing the safe state, and this will cause very big potential safety hazard to personnel and all ring edge borders.

When the elastic element 5 is located between the sleeve 3 and the outer sleeve 42, the step surface 31 is configured to provide a pushing reaction force to the elastic element 5, so that the elastic element 5 transmits a pushing force to the sliding assembly 4.

In an embodiment, referring to fig. 3, the elastic element 5 is located between the sleeve 3 and the outer sleeve 42, two ends of the elastic element 5 respectively abut against the step surface 31 and the flange 421, and because the elastic element 5 has a pushing force pushing the two ends up and down, two ends of the elastic element 5 can constantly abut against the flange 421 and the step surface 31. Therefore, the automatic pushing function can be realized only by placing the elastic element 5 between the sleeve 3 and the outer sleeve 42, so that the installation is more convenient and the connection process is simpler.
