Patent ID: 7164412

Claim:
A key-free mouse, comprising a top cover and a bottom cover connected to each other to define an internal space for receiving a circuit board therein; said top and said bottom covers being provided in an inner side at front and rear ends of a longitudinal centerline thereof with two locking pins and two locking slots, respectively, so that a longitudinal pivot axis A–A′ is defined between a front set and a rear set of said locking pin and said locking slot that engage with each other to connect said top cover to said bottom cover, and said top cover being adapted to pivotally turn about said pivot axis A–A′ by a predetermined degree relative to said bottom cover; said top cover being provided in an inner surface at positions corresponding to a left and a right switch provided on said circuit board with a left and a right strip having a predetermined length, such that when said top cover is pivotally turned about said pivot axis A–A′ and becomes laterally inclined, either said left or said right strip is brought to press against an elastickey provided on each of said left and said right switches of said mouse; wherein said left and said right strips respectively have a coil spring of a predetermined elasticity connected thereto for providing a supporting elasticity needed for said top cover to recover from a pivotally turned and laterally inclined position, and wherein said locking slot provided at the front end of sais bottom cover has a coil spring of a predetermined elasticity provided therein to locate below said locking pin at the front end of said top cover for providing a supporting elasticity to said front locking pin when said top cover is pivotally turned.
