A kind of ball type stylus and ball formula

Abstract

A ball-type stylus and a formula for rolling balls, involving electrical digital data processing, including a pen holder, a housing, a ball, a spring and a slider, the housing and the pen holder are detachably connected and provided with mounting holes; the upper end of the slider can slide Set in the installation hole, the lower end extends to the outside of the shell and is provided with a spherical shell-shaped part, and the ball is rotatably arranged in the spherical shell-shaped part; one end of the spring is in conflict with the penholder, and the other end is in conflict with the slider; the ball is in parts by mass It contains the following ingredients: 65 parts of natural rubber, 20 parts of aluminum-zirconium alloy particles, 4 parts of stearic acid, 6 parts of sulfur, 2.5 parts of anti-aging agent, and 2.5 parts of anti-scorch agent. The beneficial effect of the present invention is that the ball moves relative to the electronic device in a rolling manner, and the use of the stylus for input can effectively prevent the electronic device from being scratched. The ball can rotate in any direction through the slider and is arranged on the casing up and down to ensure smooth and unimpeded writing process, allowing the user to feel as if writing on paper.

Description

technical field [0001] The invention relates to electrical digital data processing, in particular to a ball-type stylus and a ball-rolling formula. Background technique [0002] A stylus is an electronic input device that enables writing through sliding contact between the pen head assembly and the display screen. The existing stylus is usually an all-in-one stylus with a passivated nib assembly. After the existing stylus is used for a long time, the nib assembly is likely to be damaged due to friction and become uneven, causing the user to feel smooth and poor in hand feeling when writing, and seriously damage the display screen of the electronic device. Therefore, it is necessary to design a stylus that can prevent electronic equipment from being damaged and has a long service life. Contents of the invention [0003] The invention provides a ball-type stylus and a ball-rolling formula to overcome the disadvantages of the existing stylus which have poor writing feel and...
