Specific implementation manners

[0021] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings. Only the preferred embodiments in the description are taken as examples. All other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0022] As Figures 1 - 4 shown, the following technical solutions are adopted in this specific implementation manner: It includes a lock base 1, a lock housing 2, a locking 3, a password wheel 4, a button 5, and a lock tongue 6; the lock housing 2 covers the lock base 1; the lock tongue 6 movably penetrates through the lock base 1, and the lock tongue 6 is slidably arranged with the inner end of the button 5. The pressing piece 5-1 in the button 5 is movably arranged outside the lock housing 2. An included angle is formed between the back plate 5-2 in the button 5 and the inclined slope 5-3. The lock post 3-2 in the locking 3 is movably clamped in this included angle; the locking 3 is slidably arranged on the lock base 1, and the locking 3 is movably clamped with the button 5; the password wheel 4 is rotatably installed on the shaft in the lock housing 2, and the teeth of the password wheel 4 are exposed outside the lock housing 2; the locking 3 is movably clamped with the password wheel 4.
