Switching manipulation to Eight Diagrams cipher well lid describes in conjunction with the accompanying drawings:

Steady pin (15) when Eight Diagrams cipher well lid (2) inserts in the fixedly socket (14) of well head (1), after well lid (2) put into well head (1), move by locking bolt keyhole (7) shooting the lock-bolt with locking bolt key (26), and an end of locking bolt (6) inserted well head mortise (8), again cipher key (23) is passed through keyhole (4) turning cylinder button (3), driving disc spacing pressing (5) and clutch plate (11) are rotated, and this moment, well lid promptly is in Eight Diagrams password closed condition that locks.

On the well lid Diagram of the Supreme Ultimate circle (18) mark with (

) cipher symbol, Xia Quan (19) mark with (

) during cipher symbol, with cipher key (23) by keyhole (4), a shank of the key bar groove (24) and an axle button (3) are coincide after, by the well lid Diagram of the Supreme Ultimate down the circle mark write (

) cipher symbol, clockwise rotate a button (3) driving disc spacing pressing (5) rotated, driving disc spacing pressing protruding (13) drives clutch plate protruding (10) rotates clutch plate (11), when the witness marker (25) of the shank of the key just in time be indicated to Eight Diagrams symbol outside the Tai Ji circle (

) during the position, again with key (23) by circle mark on the well lid Diagram of the Supreme Ultimate write (

) cipher symbol rotates counterclockwise, when the witness marker of the shank of the key forward to just in time indicate Eight Diagrams symbol outside the Tai Ji circle ( ) time, driving disc spacing pressing breach (20) and clutch plate breach full weight are closed, and it is corresponding with the locking bolt mouth, at this moment, again locking bolt key (26) is passed through keyhole (7) shooting the lock-bolt, then an end of locking bolt (6) just can enter master and slave Moving plate full weight and close indentation, there, and the locking bolt other end just withdraws from from well head mortise (8), and well lid promptly is in opening.

On password the circle (18) mark with (

) symbol, following circle (19) mark with (

) symbol, well lid and when being in closed condition, if will drive a well lid, after key (23) coincide by a keyhole (4) and an axle button (3), the button (3) that moves in the direction of the clock rotates driving disc spacing pressing (5), when driving disc spacing pressing protruding (13) contact clutch plate protruding (10), drive clutch plate (11) and rotate, the shank of the key witness marker (25) just in time be indicated to the outer Eight Diagrams symbol of Tai Ji circle (

) during the orientation, then the clutch plate breach is just in time aimed at locking bolt mouth (9), again key (23) is rotated counterclockwise driving disc spacing pressing, when the shank of the key witness marker (25) just in time be indicated to Eight Diagrams symbol outside the Tai Ji circle (

) during the orientation, driving disc spacing pressing breach (20) also forwards locking bolt mouth (9) to, and master and slave Moving plate breach full weight is closed, and uses locking bolt key (26) shooting the lock-bolt (6) to make the one end enter master and slave Moving plate indentation, there again, locking bolt (6) other end can withdraw from from the well head mortise, and this moment, well lid promptly was opened; Upkeep operation finishes, when closing well lid, as long as the steady pin (15) of well lid is inserted well head fixedly in the socket (14), well lid is put into well head, with locking bolt key (26) shooting the lock-bolt (6), locking bolt one end is inserted in the well head mortise (8), and after making master and slave Moving plate rotation with cipher key (23), well lid promptly is in the password closed condition that locks.
