The specific embodiment

As shown in Figure 1, 2, 3, a kind of anti-theft lock, have lock core sleeve 2 at slip lock body 1, on lock core sleeve 2, be provided with cylinder lock pearl 3, be provided with lock core 4 in lock core sleeve 2 the inners, on lock core 4, be provided with 5,1～6 group of pellet shot from a slingshot hole 6 of 1～6 group of spring leaf and keyhole 8, spring 9, alignment pin 13, wherein, between spring leaf 5, be provided with spring 10, on spring leaf 5, be provided with spring film trap 11,6 li are provided with pellet shot from a slingshot 12, have breach on pellets shot from a slingshot 12 in the pellet shot from a slingshot hole, are provided with spring being provided with on the lock core 4 on push rod 7, the push rod 7.Spring film trap 11 groove widths that are located on the spring leaf 5 are 0.5～3mm.Be located at the breach 14 that matches with cylinder lock pearl 3 on the lock core sleeve 2 and be the right angle.

When using the supporting key unlocking of the utility model anti-theft lock, be located at spring leaf 5 on the lock core 4 and overcome the spring force of the spring 10 between the spring leaf 5, the breach of spring leaf 5 is just coincide with cylinder lock pearl 3, pellet shot from a slingshot 12 overcomes the spring force on it, breach on push rod 7 and the pellet shot from a slingshot 12 is matched, lock core sleeve 2 drives cylinder lock 3 and 1 work of slip lock body, and lock is opened.When using not enough key operated supporting lock core, when key injects keyhole 8, the breach pellet shot from a slingshot 12 on the spring leaf 5 and push rod 7 can't be fully and cylinder lock pearl 3 match, lock can't be opened.
