Abstract

The invention discloses a clutch lock core structure. The clutch lock core structure comprises a base frame and a universal driving shaft, wherein the universal driving shaft comprises a driving section, an idle section, a rotation-stopping section and a rotatable section; a toggle block is fixedly connected to the universal driving shaft; a limiting piece is arranged on the base frame; a limitinghole for connecting a key with the driving section is formed in the limiting piece; a clutch is arranged under the limiting piece; an embedded pit is formed in the limiting piece, the clutch is connected with the embedded pit in a rotation-stopping mode; and a clutch hole is formed in the clutch, and the clutch hole is connected with the rotation-stopping section in a rotation-stopping mode. According to the special structural arrangement of the clutch lock core structure, the shape of the lower end of a key needs to be matched with the shape of the limiting hole, and meanwhile, the clutch needs to be moved downwards, so that the clutch, the embedded pit and the rotation-stopping section can be separated from the rotation-stopping connection at the same time to realize unlocking. In the way, the difficulty of unlocking is greatly increased, and a simple sleeve cannot be used for opening a lock. A handcuff further has the same technical effect. The clutch lock core structure is used for the lock.

Description

technical field [0001] The invention relates to a clutch lock core structure and handcuffs with the lock core structure. Background technique [0002] Many universal key locks, such as handcuffs, prison doors, vending machine doors, and product display windows, all use locks with universal keys, and one key can open all the locks. This avoids key management and improves efficiency. [0003] But the existing universal key lock is easy to be opened with simple tool, causes its security not high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a clutch lock cylinder structure which is difficult to open with common tools and handcuffs with the lock cylinder structure. [0005] The solution that the present invention solves its technical problem is: [0006] A clutch lock cylinder structure, including a base frame, a vertically arranged linkage shaft, the linkage shaft includes a driving section connected in sequen...
