The anti-pulling member 80 of this embodiment is an anti-pulling steel ball, but may be a member with other shapes.

The unlocking process of the lock cylinder of the embodiment is as follows:

unlocking the lock cylinder:

1. when the computer key 90 is inserted, the specific tooth shape on the computer key 90 pushes the locking piece 50 to overcome the elastic force of the locking reset piece 60 and move towards the inside of the lock cylinder 20, the unlocking groove 51 provides a space for the movement of the stopping part 32, and therefore the stopping of the butt joint block 36 is released;

2. the computer key 90 identifies the lock cylinder and supplies power to the locking assembly 30 through the wireless power supply part 40, reads the ID code in the lock cylinder, has correct code value, supplies power to the driving motor 35, and the driving motor 35 drives the transfer block 36 to rotate;

3. the switching block 36 rotates to enter the unlocking groove 51, and simultaneously, the switching block 36 drives the limiting block 34 to rotate, so that the avoiding hole 341 on the limiting block 34 is coaxially aligned with the locking pin 33, and the locking pin 33 moves to enter the lock core 20 to provide a moving space;

4. when the computer key 90 is turned, the locking pin 33 is pressed by the side wall of the locking groove 11 of the lock case 10 and completely enters the cylinder core 20 against the elastic force of the locking reset piece 37, so that the rotation limitation of the cylinder core 20 is released and the lock core unlocking is completed.

5. Meanwhile, during the unlocking operation, the computer key 90 cannot be pulled out since the anti-pulling member 80 cannot fall into the escape groove 12 of the lock case 10.

Locking the lock cylinder:

1. the computer key 90 is rotated to the initial position, the locking pin 33 exits the avoiding hole 341 of the limiting block 34 under the elastic action of the locking reset piece 37 and enters the locking groove 11 of the lock shell 10;

2. at this time, the abdicating groove 12 of the lock shell 10 is aligned with the anti-pulling piece 80, when the computer key 90 is pulled out, the handle body extrudes the anti-pulling piece 80 to enter the abdicating groove 12 of the lock shell 10, thereby removing the pulling-out stopping of the anti-pulling piece 80 to the computer key 90;

3. the locking member 50 moves to the locking position under the action of the locking reset member 60, and the side wall of the unlocking groove 51 of the locking member 50 extrudes the transfer block 36, so that the transfer block 36 drives the limit block 34 to rotate back to the position which is not unlocked, at this moment, the avoidance hole 341 of the limit block 34 is dislocated with the locking pin 33, so that the locking pin 33 cannot exit from the locking groove 11, and the locking of the lock cylinder is completed.

It should be noted that, a plurality in the above embodiments means at least two.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:

1. the problem that electronic contacts of a passive electronic lock cylinder in the prior art are easy to wear and oxidize, so that the lock cylinder cannot be opened or closed is solved;
