摘要： A motorbike lock includes a cylindrical body, two limit discs, two springs, a retainer, a core, a press button, a sleeve, a cap and a shackle. When the pressure button is pushed inward, the retainer is moved to force the core push the limit discs to compress the spring, with the stopper of one shackle end stopped in the cylindrical body. Then the pin in the retainer inserts in an insert hole of the cylindrical body to secure the retainer immovable, finishing locking of the lock. When the key is inserted through the press button and in the core and rotated, the pin is pressed inward to separate from the insert hole of the cylindrical body, with the retainer no longer kept immovable by the pin, letting the spring recover its elasticity to push the retainer back, with the stopper of the shackle end becoming free and the lock unlocked.

摘要： A lock core preventable to be pried unlocked includes a disguised lock core provided in front of a real lock core and bored with a key slot. When a burglar attempts to unlock the lock, he will insert a universal key into the key slot of the disguised lock core, trying to release the lock rod in the common lock core. Since the keyhole of the common lock core is not aligned to the key slot of the disguised lock core, the universal key can only be inserted in the key slot of the disguised lock core, impossible to reach in the keyhole of the real lock core. Thus, despise being turned around, the universal key can only make the disguised lock core rotate idly, with the real lock core still locked, having an excellent effect of anti-burglary.

摘要翻译： 可防止被锁定的锁芯包括设在真实锁芯前面的伪装锁芯，并且用钥匙槽钻孔。 当防盗器试图解锁锁时，他会将通用钥匙插入伪装的锁芯的钥匙槽中，试图将锁芯放在公共锁芯中。 由于普通锁芯的锁孔与伪装锁芯的键槽不对齐，所以通用键只能插入伪装的锁芯的键槽中，无法到达锁芯的锁孔。 因此，鄙视转身，通用钥匙只能使伪装的锁芯空转，真正的锁芯仍然锁定，具有很好的防盗效果。
