(57) 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
