Title: TOUCH STYLUS
Abstract:
A touch stylus comprises a touch control member (21) disposed in a casing (20) of the stylus, a main control module (22) for changing thickness of the handwriting on a touch screen, and a limiting member (23) fixedly provided within the casing (20) of the stylus for limiting movement of the touch control member (21). Wherein, the touch control member (21) is elastically connected to the limiting member (23), and the head of the touch control member (21) constitutes a nib. The touch stylus further comprises a magnetic component (24) disposed within the casing (20) and fixed on the touch control member (21) to move as the nib moves, and a detection module (25) provided within the casing (20) for detecting a magnetic field strength of the magnetic component (24); wherein the magnetic component (24) and the detection module (25) are separated from each other; and the detection module (25) is electrically connected to the main control module (22); and writing force of the touch control member (21) on the touch screen is in a pre-set proportion with the detected magnetic field strength of the magnetic component (24).
