The driving member 32 is movably disposed in the lock core 20, the driving end 322 and the clutch end 321 are respectively disposed on two opposite sides of the driving member 32, and the driving end 322 of the driving member 32 extends into the unlocking hole, so that when the computer key is inserted into the lock core 20, the computer key drives the driving member 32 to move along the radial direction of the lock core 20 by pressing the driving end 322, and the clutch end 321 is used for being matched with the clutch blade 33, in this embodiment, the clutch end 321 is set to be in a tooth shape. The clutch blade 33 is inserted into the clutch member 31, one side of the clutch blade 33 is provided with a plurality of clutch grooves 331, the other side is provided with an avoiding groove 333, and the clutch grooves 331 are matched with the clutch ends 321 in shape. The clutch blade 33 also has two directions of movement, namely an axial movement along the cylinder core 20 under the drive of the clutch member 31 and a radial movement along the cylinder core 20 relative to the clutch member 31, wherein the axial movement of the clutch blade 33 switches it between a position aligned with and offset from the drive member 32. Specifically, as shown in fig. 1 to 7, when the lock cylinder is normally used and code change is not required, the clutch member 31 is located at the engaging position, the clutch blade 33 is aligned with the driving member 32, the engaging end 321 is matched or assembled with the engaging slot 331, the engaging end 321 extends into one of the engaging slots 331, the driving member 32 is driven by a computer key to move, the driving member 32 drives the clutch blade 33 to move synchronously, at this time, when the clutch blade 33 moves until the engaging slot 333 is aligned with the locking member 40, the locking member 40 has a moving space, the locking member 40 can exit the engaging slot 11 to exit the lock case 10, the locking member 40 no longer locks the lock cylinder 20 and the lock case 10, and the lock cylinder 20 can be rotated and unlocked; as shown in fig. 8 to 10, when the lock core needs to change the code, the lock core is unlocked, the engaging element 31 is pushed to the disengaging position from the engaging position by using a coding tool after unlocking, at this time, the clutch blade 33 and the driving element 32 are axially staggered by a certain distance, the clutch end 321 exits the clutch slot 331, the driving element 32 does not drive the clutch blade 33 to move any more, the driving element 32 can move in an idle stroke relative to the clutch blade 33 under the drive of a corresponding computer key, so that the clutch end 321 is switched among the clutch slots 331 on the premise of not changing the position of the clutch blade 33, the clutch slot 331 in butt joint with the clutch end 321 is changed, the coding state of the coding component is changed, and the code change is realized. The radial movement of the clutch leaf 33 relative to the clutch part 31 is carried out by the drive part 32, which can switch the escape groove 333 on it between a position aligned and offset with respect to the blocking element 40, in order to allow the blocking element 40 to be withdrawn from the blocking groove 11 or to stop the blocking element 40 in the blocking groove 11. It should be noted that the clutch blade 33 changes its alignment with the locking member 40 only when the clutch member 31 is in the engaged position, and the position of the clutch blade 33 does not change because it is not carried by the clutch member 31 when the clutch member 31 is in the disengaged position.

The engaging grooves 331 of the present embodiment form a tooth shape, and the purpose of the engaging grooves 331 is to insert the engaging ends 321 into different engaging grooves 331 so as to adapt to unlocking grooves 152 of different computer keys, thereby realizing code conversion.

Specifically, when the clutch member 31 is located at the engaging position, the spring piece 34 is misaligned with the separating groove 13, and since the spring piece 34 is stopped by the inner wall of the lock case 10, the spring piece 34 is accommodated in the clutch member 31, and the clutch member 31 can freely move axially; when the clutch piece 31 is pushed by using the coding tool, the clutch piece 31 moves from the combining position to the separating position, at the moment, the elastic block 34 is aligned with the separating groove 13, the elastic block 34 extends into the separating groove 13, so that the clutch piece 31 is clamped at the separating position, therefore, when a computer key is replaced, the original computer key and the coding tool are pulled out together after unlocking, the position of the clutch piece 31 cannot be influenced, another computer key is subsequently inserted into the lock liner 20 for replacing, after the replacement is completed, when the lock liner 20 is rotated reversely and reset, the side wall of the separating groove 13 extrudes the elastic block 34, the elastic block 34 is withdrawn from the separating groove 13 and retracted into the clutch piece 31, and the clutch piece 31 can be unlocked from the separating position and can move to the combining position. The elastic block reset piece 35 is a spring, which abuts against the elastic block 34 and provides a reset force for the elastic block 34 to extend into the separation groove 13, so that when the clutch piece 31 moves to the separation position, the elastic block 34 automatically extends into the separation groove 13 to lock the clutch piece 31.

In the present embodiment, the separating groove 13 and the locking groove 11 are spaced apart by a predetermined angle in the circumferential direction of the lock case 10. This is because the engagement between the locking groove 11 and the locking member 40 is performed when the lock cylinder is locked, and the engagement between the separation groove 13 and the tumbler 34 is performed when the lock cylinder is swapped, the lock cylinder is unlocked first when the swap is performed, the cylinder core 20 is rotated 90 degrees, that is, the engagement between the separation groove 13 and the tumbler 34 is performed when the lock cylinder is unlocked, and therefore, the locking groove 11 and the separation groove 13 need to be circumferentially spaced by 90 degrees.

As shown in fig. 2 and 3, the lock cylinder further comprises a clutch reset piece 60, a driving reset piece 70, a locking reset piece 80, the clutch reset piece 60, the driving reset piece 70 and the locking reset piece 80 are all springs, wherein the clutch reset piece 60 is abutted to the clutch piece 31 and provides a reset force for the clutch piece 31 to move to a combination position, so that the clutch piece 31 is driven to reset automatically after the elastic block 34 unlocks the clutch piece 31, the clutch reset piece 60 can be completed in the final process of assembly, the assembly difficulty is reduced, the assembly is simple, and the operation is convenient. The drive return member 70 abuts against the drive member 32 and provides the drive member 32 with a return force that moves the clutch blade 33 to a position offset from the latch member 40, thereby achieving automatic return upon latching.
