A transmission member return spring 800 is provided between the transmission member 8 and the housing 2. When the coded lock assembly 6 is in a locked state, at least one of the digital wheels 611 of the three digital wheel sets 61 is not the correct unlocking number, the notch 6121 of the corresponding inner sleeve 612 is staggered with the corresponding clamping block 82 of the transmission piece 8, the first limiting hooks 42 and the second limiting hooks 81 are mutually limited one by one, and the transmission piece reset spring 800 is in an elastic deformation state; when the coded lock assembly 6 is in the unlocking state, three clamping blocks 82 on the transmission piece 8 are clamped into the corresponding notches 6121 of the inner sleeve 612. In the process that the number wheel 611 rotates to an incorrect unlocking number, the number wheel 611 rotates to drive the inner sleeve 612 to rotate, and the inner sleeve 612 rotates to push the transmission piece 8 to move through the clamping block 82; at the moment when the number wheel 611 just rotates to the correct unlocking number, the elastic force generated by the elastic deformation of the transmission member return spring 800 drives the transmission member 8 to move, so that the clamping blocks 82 are clamped into the gaps 6121, the first limiting hooks 42 and the second limiting hooks 81 are staggered one by one, and the limit between the transmission member 8 and the limiting member 4 is released.

the coded lock assembly comprises a coded wheel set, the coded wheel set is connected with a transmission piece in a linkage way, and a transmission piece reset spring is arranged between the transmission piece and the shell;
when the coded lock assembly is in a locking state, the transmission piece reset spring is in an elastic deformation state; when the coded lock assembly is switched from a locking state to an unlocking state, the elastic force generated by elastic deformation of the reset spring of the transmission piece drives the transmission piece to move, and the transmission piece moves to the position that the second limit hook is staggered with the first limit hook;
the key lock assembly comprises a lock core and a lock core baffle, and the lock core baffle is simultaneously connected with the lock core and the transmission piece in a linkage way;
when the unlocking is carried out through the key, the key drives the lock core to rotate, the lock core drives the lock core baffle to rotate, and the lock core baffle pushes the transmission piece to move so as to realize unlocking.
2. A latch according to claim 1, wherein: the password wheel set comprises a digital wheel set, the digital wheel set comprises a digital wheel and an inner sleeve, a notch is formed in the inner sleeve, and a clamping block is arranged at a position, corresponding to the notch of the inner sleeve, of the transmission piece;
when the coded lock assembly is in a locking state, the clamping block of the transmission piece is staggered with the notch of the inner sleeve; when the coded lock component is in an unlocking state, the elastic force generated by the elastic deformation of the reset spring of the transmission piece drives the transmission piece to move to the notch of the clamping block clamped into the inner sleeve.
3. A latch according to claim 2, wherein: the coded lock assembly further comprises a number changing piece, the number changing piece is provided with a pushing block protruding out of the shell, the number changing piece is positioned below the transmission piece, the digital wheel set further comprises an inner sleeve spring, and the inner sleeve spring is arranged between the inner sleeve and the digital wheel;
when the number changing piece is not used, the number changing piece props against the lower end surface of the transmission piece, and the inner sleeve spring elastically deforms; when the number changing piece is used, the number changing piece moves to be separated from the transmission piece, and the elastic force generated by the elastic deformation of the inner sleeve spring drives the inner sleeve and the transmission piece to move, so that the inner sleeve and the digital wheel are separated.
4. A latch according to claim 3, wherein: the number changing piece is provided with a positioning block, the shell is provided with a first positioning hole and a second positioning hole, and the depth of the second positioning hole is larger than that of the first positioning hole;
when the number changing piece is not used, the positioning block of the number changing piece is positioned in the first positioning hole; when the number changing piece is used, the number changing piece moves to the position where the positioning block is located in the second positioning hole.
5. A latch according to claim 3, wherein: the number changing piece is provided with a bump, the bump is provided with a yielding hole, and the transmission piece is provided with a limiting block;
when the coded lock assembly is in a locking state, a limiting block of the transmission part is staggered with a yielding hole of a lug on the number changing part, and the limiting block limits the movement of the number changing part; when the coded lock component is in an unlocking state, the limiting block is aligned with the yielding hole, and the number changing piece is movable.
6. A latch according to claim 2, wherein: the shell is provided with a transparent lens, the transparent lens corresponds to the digital wheel, and the numbers corresponding to the digital wheel can be seen through the transparent lens.
7. A latch according to claim 1, wherein: the lock core baffle is provided with a shifting block, the transmission piece is provided with a stop block, and when the lock core baffle rotates, the shifting block pushes the transmission piece to move through the stop block.
