S3, when the backward moving distance of the outer sleeve (36) reaches a second threshold value, the trigger block (39) is attached to the fixed block (51), the trigger block (39) pushes the fixed block (51) along with the continuous backward moving of the outer sleeve (36), the fixed block (51) drives the extension plate (53) to compress the second spring (54) and simultaneously stretches out from the inside of the shell (11), at the moment, the front surface of the fixed block (51) is attached to the back surface of the cabinet door in a sliding way, and the limiting sleeve (14) and the fixed block (51) are mutually matched to finish clamping and fixing of the cabinet door;

S4, when the backward moving distance of the outer sleeve (36) reaches a third threshold value, the trigger block (39) is in contact with the extension plate (53), meanwhile, the rear end of the trigger rod (38) is in front contact with the back plate (62), the back plate (62) compresses the third spring (61) along with the continuous backward moving of the outer sleeve (36), and meanwhile, the limit block (66) is driven to slide backwards through the side plate (64) and the connecting rod (65);

S5, when the backward moving distance of the outer sleeve (36) reaches a fourth threshold value, the two annular magnets (63) are mutually adsorbed, meanwhile, the limiting block (66) enters the inner side of the limiting groove (52) to complete limiting of the fixed block (51), at the moment, the first spring (35) is compressed to an extreme value, the outer sleeve (36) moves to the rear end of the outer reciprocating thread of the reciprocating screw (33), the installation and locking operation are synchronously completed, and the driving motor (32) is powered off;

s6, when the FPC is unlocked, an unlocking instruction is sent to the FPC flexible board (21), the driving motor (32) is electrified again to drive the reciprocating screw (33) to rotate, the reciprocating screw (33) drives the outer sleeve (36) to move forwards for resetting, and in the advancing process of the outer sleeve (36), the back board (62) does not synchronously move due to the mutual adsorption of the two annular magnets (63), and the limiting block (66) continuously keeps the limiting state of the fixed block (51);

S7, when the advancing distance of the outer sleeve (36) reaches a fifth threshold value, the compressed first spring (35) is completely restored, the L-shaped rack (41) drives the gear (42) to reversely rotate along with the continuing advancing of the outer sleeve (36), the lock tongue plate (43) gradually rotates anticlockwise to start resetting, when the advancing distance of the outer sleeve (36) reaches a sixth threshold value, the outer sleeve (36) reaches the forefront end of the reciprocating thread outside the reciprocating screw (33), namely the initial position, the unlocking operation is completed, and the driving motor (32) is powered off.
