Manual device (200), comprising a casing (212) having a first distal end (12-1) and a second distal end (12-2), a first head (16A) and a second head (16B) that are movable axially between a use position and a retracted position, and a single mechanism (214) that is configured to bring the first head (16A) and the second head (16B) from the retracted position to the use position and vice versa, the mechanism (214) comprising at least one carriage (214A1, 214A2) having at least one head selected from the first head and the second head (16A, 16B) and a single spring (214B).

A stylus suitable for an electronic device is provided. The stylus comprises a pen barrel and a pen core. The pen barrel has a sidewall and at least one first protrusion, and the first protrusion is located at an inner side of the sidewall. The pen core movably passes through the pen barrel. The pen core has a pen tip and at least one second protrusion. Under a first status, the first protrusion and the second protrusion are dislocated from each other. Under a second status, the first protrusion and the second protrusion are aligned with each other to make a part of pen barrel expand and deform.
