When the sealing box 1 tilts to one side, the detection ball 95 at the bottom of the vertical rod 94 slides inside the arc groove, so that the detection ball 95 abuts the switch on the same side. After triggering the first switch 98 or the second switch 910, it means that emergency measures are needed, and it is necessary to start the motor 82 to drive the cross rod 83 to rotate, so that the cross rod lock 84 corresponds to the position of the cross groove 85, and then start the third electric push rod 81 to pull the cross rod lock 84 out of the C-shaped plate 2 to release the limit of the controller, and simultaneously provide a signal to the positioning component 710 to release the limit of the combing mechanism 7. After the synchronous release, as in Example 1, the gravity controller and the line are synchronously self-adjusted and rotated, and a signal is provided to the inflatable protection component 67 for secondary protection.
