Press-action device

A press-action device (1, 1a, 1b, 1c, 1d) comprises a holding barrel (10, 10a, 10c, 10d), a push button (20, 20a, 20b, 20c, 20d), a rotation module (50, 50a, 50b, 50c, 50d), and an auxiliary spring (80, 80b, 80c, 80d, 82a, 84a). The holding barrel (10, 10a, 10c, 10d) comprises a window (16, 16a, 16c, 16d), and the rotation module (50, 50a, 50b, 50c, 50d) includes at least one rotation barrel (10, 10a, 10c, 10d) on which a plurality of patterns (74, 74b) can be attached. When a user pushes the push button (20, 20a, 20b, 20c, 20d), the window (16, 16a, 16c, 16d) will randomly display one of the patterns (74, 74b) on the rotation barrel (10, 10a, 10c, 10d).
