Expandable electronic stylus

摘要

An extendable electronic stylus is described. The extendable electronic stylus has a distal end that provides an electronic input to an electronic device and a first cam with an elongated member that extends between a proximal end of the stylus and its distal end. The stylus also includes a second cam that rotates relative to the first cam when the proximal end of the stylus is pushed in a distal direction. The pushing of the proximal end of the stylus causes a surface of the second cam to contact the first cam surface. The stylus also includes a cover with a first look surface. The rotation of the second cam relative to the first cam cause a second lock surface of the second cam to abut the first lock surface, thereby locking the second cam in a fixed position relative to the first cam.

1. A device comprising:
an electronic stylus including:
a distal end configured to provide an electronic input to an electronic device;a first cam having a first cam surface, the first cam having an elongated member extending between a proximal end of the stylus and the distal end;a second cam configured to rotate relative to the first cam when the proximal end of the stylus is pushed in a distal direction, the pushing of the proximal end of the stylus causing a second cam surface of the second cam to contact the first cam surface and cause the rotation of the second cam relative to the first cam; anda cover having a first lock surface, the rotation of the second cam relative to the first cam causing a second lock surface of the second cam to abut the first lock surface so as to lock the second cam in a fixed position relative to the first cam.
