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.

Mouse device with prestress regulating structures

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.
