Patent ID: 8884879

Claim:
An input device with adjustable holding angle, comprising: a bottom shell, defining a plane thereon and an erective direction perpendicular to the plane, wherein a longitudinal direction and a transverse direction perpendicular to the longitudinal direction are defined along the plane; an omnidirectional rotating module, disposed at a front end of the bottom shell: a top housing unit, arranged above the bottom shell for an user's palm placed thereon, having a front part rotatably connected a top portion of the omnidirectional rotating module, and a rear part opposite to the front part along the longitudinal direction; and an angle adjusting device, opposite to the omnidirectional rotating module along the longitudinal direction, disposed between the top housing unit and the bottom shell, wherein the angle adjusting device includes: an accommodating housing fixed on the bottom shell; a linking module having a frame portion and a plurality legs extended downwardly from a bottom edge of the frame portion, wherein the frame portion is disposed in the accommodating housing in swingable manner along the longitudinal direction; a pitching unit having a thread tube fixed in the frame portion of the linking module, and a liftable erective rod extending into the linking module in a rotatable manner along the erective direction, wherein the liftable erective rod has a thread portion screwed to the thread tube; wherein a top end of the erective rod is rotatably connected to the rear part of the top housing unit and exposed outside the top housing unit; thereby when the erective rod is raised or lowered relative to the bottom shell by rotating the top end thereof, the rear end of the top housing unit is uplifted or lowered to adjust a pitching angle of the top housing unit; and a rolling unit, having a guiding slider grasped by the legs of the linking module under the thread tube, and a lateral rod extending into the accommodating housing along the transverse direction, wherein the guiding slider has a thread portion formed at a central part thereof, wherein the lateral rod has a thread portion screwed to the thread portion of the guiding slider to move the legs of the linking module; wherein the lateral rod has a head portion exposed outside the accommodating housing; thereby when the head portion of the lateral rod is rotated to move the lateral rod along the transverse direction forward or reward relative to the accommodating housing, the legs of the linking module are moved along the transverse direction by the guiding slider screwed with the lateral rod so that the linking module and the erective rod are swung along the longitudinal direction, and the top end of the erective rod moves the rear part of the top housing unit along the transverse direction to adjust a rolling angle of the top housing unit.
