Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to the field of mechanical locks. Background technique [0002] In daily life, door locks are often used. However, the existing locks have disadvantages such as bulky size, troublesome installation, large trauma to the door, easy duplication of keys, large door opening rotation angle, high key mutual opening rate, and short service life. Therefore, a lock with a well-designed mechanism can not only prolong the time of destruction or opening, but also relatively increase the safety of home and personal property. [0003] In view of the above requirements, it is expected to design a more suitable structure for the structure between the key and the lock to effectively meet the above requirements. Contents of the invention [0004] The present invention overcomes the defects of the prior art and provides a thimble type double-opening round lock which is easy to install and difficu...
