Abstract: A mouse device with prestress regulating structures has a body with a space, a printed circuit board and a micro switch are disposed in the space. The micro switch is electrically connected to the printed circuit board. A button unit is disposed in the body by means of a shaft and is available to move up and down relative to the body. The button unit has a first end and a second end and is configured to engage with the micro switch. A first prestress regulating structure is accommodated in the space and abutted against the bottom side of the first end for regulating a first prestress force applied to the first end. A second prestress regulating structure is accommodated in the space and abutted against the bottom side of the second end for regulating a second prestress force applied to the second end.

Abstract: A computer mouse with an adjustable palm rest includes a main housing defined with a longitudinal direction and a traverse direction and has a carriage. A connecting base is rotatably connected to the carriage along a first axis. A supporting casing has a front wall and a rear wall. A palm-resting cover is fixed to the supporting casing. The front wall is closed to the connecting base. The supporting casing is rotatably connected to the connecting base along a second axis. The supporting casing can be arranged at different oblique angles related to the connecting base. A positioner chain is formed on a surface of the connecting base or the supporting casing and has a plurality of positioning dimples. A positioning assembly abuts against one of the dimples and retains the supporting casing at one of the oblique angles related to the connecting base.

Abstract: A mouse wheel assembly is provided according to the present invention. The mouse wheel assembly includes a locating frame, a swing frame, and a scroll wheel. The swing frame is pivoted on the locating frame through a shaft and moved up and down relative to the locating frame. The scroll wheel is disposed in the swing frame and rotated relative to the swing frame. The bottom side of the swing frame is formed with a platen. The swing frame is rotated relative to the locating frame by a predetermined angle when the scroll wheel is depressed, so the platen is pressed against the micro switch.
