When inputting a password, a user rotates the rotary sleeve 103 in the direction of meshing the pawl 122 with the ratchet 121, the rotary table 112 is driven to rotate by the pawl 122 and the ratchet 121, after the password to be input is turned to the input position, the rotary sleeve 103 is pressed down, and the bump 118 on the bottom surface of the rotary table 112 presses down the password input button 120 at the corresponding position to complete one-bit password input. In the downward moving process of the rotary table 112, the threaded sleeve 110 rotates relative to the screw rod 109, at this time, the relative rotation direction between the rotary table 112 and the threaded sleeve 110 is the direction in which the unidirectional bearing 111 allows rotation, so that the rotary table 112 cannot rotate when moving downward, after character code input is completed, a user releases the rotary sleeve 103, the rotary sleeve 103 rises and resets under the action of the first spring 13, meanwhile, the rotary table 112 rises and resets under the action of the second spring 15, during the rising process of the rotary table 112, the threaded sleeve 110 reversely rotates, at this time, the relative rotation direction between the rotary table 112 and the threaded sleeve 110 is the locking direction of the unidirectional bearing 111, so that the rotary table 112 rotates together with the threaded sleeve 110, and after the threaded sleeve 110 reaches the top limit position, the relative rotation direction between the rotary table 112 and the threaded sleeve 110 becomes the direction in which the unidirectional bearing 111 allows rotation again, so that the rotary table 112 still continues to rotate for a period of time under the action of inertia, and in the rotating process of the rotary table 112, the pawl 122 cannot mesh with the ratchet 121. When the next code is to be input, the user rotates the rotary sleeve 103 again in the direction in which the pawl 122 is engaged with the ratchet 121, so as to drive the rotary table 112 to rotate, and the next code is transferred to the input position for input. The rotation speed and time of the dial 112 after each character code input are related to the speed of the user releasing the rotary sleeve 103, so the stop angle of the dial 112 after rotation is uncertain, and an lawbreaker cannot infer the content of the character code by recording the rotation angle of the rotary sleeve 103 when the character code is input next time. The invention can realize that the position of the code is disturbed after each code is input, has stronger anti-interference and peeping-proof performance compared with the prior code input device, and can greatly enhance the safety of the coded lock.
