The utility model discloses a theory of operation of lock:

when the lock needs to be unlocked, as shown in fig. 4, the pushing slider 411 in the pushing block 41 slides in the forward direction, when the pushing rotating block 412 in the pushing block 41 touches the touching portion 31 of the lock cylinder 3, because the lock cylinder 3 cannot move, at this time, the pushing rotating block 412 rotates to avoid the obstruction of the touching portion 31, after the pushing rotating block 412 crosses the touching portion 31, it returns to the original position under the action of the first return spring 413, and then, the pushing slider 411 slides in the reverse direction, when the touching portion 31 of the lock cylinder 3 is touched again, the pushing rotating block 412 touches the limiting portion 4111, the limiting portion 4111 limits the pushing rotating block 412 from rotating to the limiting portion 4111 side, at this time, the pushing rotating block 412 cannot avoid the touching portion 31, at this time, the first inclined guiding surface 4121 contacts and slides relative to the second inclined guiding surface 311, so that the limiting groove 32 is disengaged from the limiting step 51, and the pushing slider 411 moves in the reverse direction, the pushing rotating block 412 drives the lock cylinder 3 to unlock the lock body 2, so as to realize unlocking, see fig. 5. When the lock needs to be locked again after unlocking, the rotating block 411 is pushed to move to be separated from the touch part 311, at the moment, the lock cylinder 3 returns to the position where the lock body 2 can be locked under the action of the return elastic piece 42, and at the moment, the second return spring 52 pushes the limiting groove 32 to be sleeved into the limiting step 51, so that locking can be achieved. Of course, the structure of the middle pushing block of the present invention can also be other structures, for example: promote the piece and adopt elastic material to make, when promoting piece forward movement, elastic deformation avoids touching portion, when promoting piece reverse movement touching to touching portion, the deformation elasticity that return elastic component can be overcome to the deformation elasticity that promotes the piece to the realization can be with the lock core toward will be removed by lock body unblock direction. The utility model discloses a lock is when using, only can be through the inside promotion piece of lock seat with the lock core unblock, when applying force from the fore shaft position, owing to there is limiting mechanism's effect, can't promote, avoids other people to utilize the instrument to promote the lock core from the fore shaft and will be by the lock body unblock, has strengthened the security of lock.

Further, referring to fig. 2 and 6, the sliding of the pushing slider 411 is realized through a screw mechanism 6, the screw mechanism 6 includes a motor 61 and a screw 62, the screw 62 is in threaded connection with the pushing slider 411, and the lock base 1 is provided with a rotation limiting portion 12 for limiting the rotation of the pushing slider 411. Due to the action of the rotation limiting part 12, when the screw rod 62 rotates, the screw rod cannot drive the pushing slide block 411 to rotate, and at the moment, under the action of the thread structure, the pushing slide block 411 slides along the length direction of the screw rod 62.
