Problems solved by technology

However, the convenient opening methods of these locks have left hidden dangers and left opportunities for illegal personnel to unlock, so slowly many illegal unlocking methods have been produced, such as: drilling, cutting, cutting, propping, jacking, etc. There is even a master key, and a master key can be used to open a variety of locks with different structures.
The invention with the patent application number "200510033822.0" discloses a coin-operated indirect opening lockset, which is composed of a lock body, a U-shaped ring, a lock sleeve, a key holder, a transmission mechanism, a drive mechanism and a locking device, and can overcome existing The direct unlocking structure of the key has the disadvantage that it is easy to be opened illegally. However, when the lock is opened in this invention, the key and the handle cannot be separated, and the matching key needs to be put into the key holder. The disadvantage of copying, its application is limited to padlocks
