Abstract
A figure wheel locking device includes a housing, a key locking mechanism, a pushing assembly, a plurality of figure-detecting members, and a figure locking mechanism. The key locking mechanism is sleeved in the housing. The pushing assembly is movably located in the housing. Each of the figure-detecting members has a first rotating member. The figure locking mechanism has a plurality of figure wheels, and each of the figure wheels has a second rotating member. The direction of the first rotating member is defined as a first rotating axis. The direction of the second rotating member is defined as a second rotating axis. The second rotating axis and the first rotating axis are interlaced to each other. The second rotating member drives the first rotating member. Thereby, the compound locking device having a key locking mechanism and a figure locking mechanism prevents the figure wheels from becoming axially disposed in serial.
