It will be appreciated that the sensing mechanism 6 senses the position of the door leaf 2 relative to the case 1 (e.g. based on the sensed data of the angle sensor 61 or the distance sensor 62), when the angle between the door leaf 2 and the case 1 is between 25 ° and 30 ° (i.e. the first preset condition, the preferred angle range is 26 ° and 29 °, and the preferred angle range is 27 ° and 28 °), the sensing mechanism 6 continues to sense the position of the turnover beam 4 relative to the case 1 (e.g. based on the sensed data of the contact sensor 63), and when the turnover beam 4 is confirmed to be in the abducted state (e.g. the contact sensor 63 does not receive the signal of the rack block 54 approaching the stop 56), the actuating mechanism 5 resumes the operation, and moves the rack block 54 approaching the stop 56, and the telescopic rod 55 or other power element stops the operation, and the turnover beam 4 moves to the inside-out state.
