According to fig. 3 and 4, the execution motor 9 is started by the electronic module 8 after authorization for the identification system 23. The motor 9 is operated to rotate the toggle block 11 downwards with the clutch 5 by the transmission shaft 10. The toggle block 11 overcomes the clutch reset torsion spring 22 on the clutch 5 to rotate the clutch 5, so that a gap is generated between the clamping seat 6 and the main lock tongue 3, and the main lock tongue 3 can rotate downwards when the gap is large enough. The main bolt 3 starts to rotate under the action of an external mechanism, and when the main bolt 3 rotates to a certain degree, the main door body is opened.
