[0026] Working principle: When the components of the CAN bus communication module need to be maintained, the connecting block 7 is pulled through the push groove 15, so that the movable connecting block 7 can drive the slider 6 to move horizontally on the limit rod 5, and at the same time, the moving slider 6 will squeeze the spring 11 on the inner wall of the lower protective box 1, so that the spring 11 is in a taut state, and the moving connecting block 7 will drive the fixed block 8 to move. When the fixed block 8 is separated from the fixed groove 9 after movement, the fixation of the movable block 4 and the torsion spring 10 can be released, so that the torsion spring 10 can flip and rebound, thereby making the flip and rebound The torsion spring 10 drives the movable block 4 and the fixed slot 9 to flip. When the flipped fixed slot 9 no longer corresponds to the fixed block 8, the pulled connecting block 7 is released, so that the spring 11 is no longer restricted by the tension and rebounds, so that the rebounding spring 11 can drive the slider 6, the connecting block 7 and the fixed block 8 to move. At this time, the fixation between the lower protective box 1 and the upper protective box 2 has been released, and the lower protective box 1 and the upper protective box 2 can be separated. Then, after pulling the upper protective box 2, the upper protective box 2 can be removed from the lower protective box 1, so as to facilitate the CAN bus in the lower protective box 1. The communication module components are maintained. When the maintenance of the components of the CAN bus communication module is completed, the upper protection box 2 is re-placed on the lower protection box 1, and then the connecting block 7 is pulled through the push groove 15, so that the moving connecting block 7 drives the slider 6 and the fixed block 8 to move while keeping the spring 11 in a taut state. When the moved fixed block 8 does not affect the flipping of the movable block 4, the movable block 4 is flipped in the reverse direction, so that the flipped movable block 4 can drive the fixed groove 9 to flip, and at the same time, the flipped movable block 4 will drive the torsion spring 10 on the connecting rod 3 to flip and stretch, so that the torsion spring 10 In the flipped and stretched state, when the flipped fixing groove 9 corresponds to the fixing block 8, the pulled connecting block 7 is released, so that the spring 11 is no longer restricted by the tension and rebounds, so that the rebounding spring 11 drives the slider 6, the connecting block 7 and the fixing block 8 to move. When the moving fixing block 8 is inserted into the fixing groove 9, the torsion spring 10 is restricted, so that the torsion spring 10 will no longer flip and rebound, and the movable block 4 can no longer flip, thereby completing the fixation between the lower protection box 1 and the upper protection box 2, and completing the protection of the CAN bus communication module components in the lower protection box 1.
