ABSTRACT:
A key-free mouse includes a top cover and a bottom cover connected to each other through a pivotal connection of locking pins to locking slots. The locking pins and the locking slots are respectively provided at inner side of the top and the bottom covers at front and rear ends of a longitudinal axis thereof, so that the top cover is pivotally turnable about the longitudinal axis by a predetermined degree relative to the bottom cover to actuate a left or a right switch provided in the mouse. Elastic elements such as springs are provided in the mouse separately at predetermined positions for providing the top cover with suitable supporting elasticity to recover from a pivotally turned and laterally inclined position.
