Abstract

The invention discloses a panel fixing device of an anti-theft lock. The device comprises a clutch device and a panel, wherein the clutch device comprises a clutch outer body, a handle return spring and a clutch inner core, a first lock cylinder hole penetrating through a front end face and a rear end face of the clutch inner core is formed in the clutch inner core, and a second lock cylinder holepenetrating through a front end face and a rear end face of the clutch outer body is formed in the clutch outer body, a third lock cylinder hole penetrating through a front end face and a rear end face of the panel is formed in the panel, the handle return spring comprises a pair of hooked ends, and the panel covers the clutch device. The invention further discloses an anti-theft lock. The panelfixing device of the anti-theft lock has the effect of better preventing theft, can better protect the lock body structure, and prevents the situation that a handle mouth and the second lock cylinderhole get loosened due to the fact that a handle drives the handle mouth to perform lateral torque twisting during use.

Description

technical field [0001] The invention relates to the technical field of mechanical door locks, in particular to a panel fixing device of an anti-theft lock and an anti-theft lock comprising the panel fixing device of the anti-theft lock. Background technique [0002] At present, commercially available anti-theft locks all include inner and outer handles, inner and outer panels, lock cylinders, and lock body structures.
