Changeable combined mechanical key

Abstract

The invention relates to a changeable combined mechanical key and belongs to the technical field of encrypted lock key structures. The changeable combined mechanical key is characterized by comprising a holder, a spoon-shaped assembly and a protective bush, wherein the holder is connected to the end of a key handle detachably. The changeable combined mechanical key can avoid theft and copy, has unique advantages in important fields such as safes, important military places, banks, household smart anti-theft locks and other fields needing security, cannot go wrong like electronic keys caused by electronic circuit device software and the like, and is irreplaceable. Furthermore, by means of the changeable combined mechanical key, the processing technique of the traditional mechanical keys is changed, energy is saved, consumption is reduced, and application prospect is wide.

Description

Technical field The invention relates to a variable combination mechanical key, and belongs to the technical field of encryption lock key structures. Background technique At present, with the improvement of people's living standards, higher and higher requirements are put forward for home safety, and the anti-theft door locks that are adapted to it are also constantly moving towards the goal of higher anti-theft; in many other important fields, locks are required The anti-theft performance puts forward higher requirements. In recent years, many lock manufacturers have developed products with high anti-technological opening capabilities, such as mechanical anti-theft locks and electronic smart anti-theft locks, but all mechanical anti-theft locks are opened by mechanical keys, and almost all electronic smart anti-theft locks A set of emergency opening mechanical keys must be reserved, which brings a new problem. If this mechanical key is stolen or copied, theft will still oc...
