Description

Lock set

Technical Field

The invention relates to the technical field of locks, in particular to a lock.

Background

The lockset is a sealing tool, and comprises a lock, a key and accessories thereof, and is generally interpreted as a sealing device which can be opened by the key, the lockset is widely applied to daily life, and the lockset can be opened by commands such as light, electricity, magnetism, sound, fingerprint and the like besides being opened by the key. Locks are also commonly used in some outdoor devices to keep safe or theft-proof, such as in monitoring wells, and because of the harsh outdoor environment, only keys are often used as a means of unlocking the lock. As in chinese patent document CN201031853Y, a wheel anti-theft lock is disclosed, which comprises a screw element and a key, wherein the screw element has a coupling hole at the top, the key comprises a force receiving portion that can be pulled and a coupling portion that mates with the coupling hole, wherein the screw element and the key are made of stainless steel material, the coupling hole of the screw element is an inner-pattern hole with a corner, and the coupling portion of the key is an outer-pattern portion with a corner. When the lock is used, the coupling part of the key is arranged in the coupling hole, and then the key is turned to drive the screw element to rotate so as to unlock. In this structure, when using the spanner that can cooperate with the spiro union component, need not the key and can open the locking component, the security is relatively poor.
