Active capacitance pen

Abstract

The invention discloses an active capacitance pen. The active capacitance pen comprises a pen body, wherein a refill lower cover is placed on an inner wall of the pen body; a refill upper cover is placed on the inner wall of the pen body; one side of the refill lower cover is matched with one side of the refill upper cover; the inner wall of the pen body is matched with an outer wall of the refill upper cover; an outer wall of the refill lower cover is matched with the inner wall of the pen body; one end of the pen body is connected with a pen point in a threaded and sleeved mode; one end of the pen body is provided with a threaded groove; one end of the pen point is fixedly connected with a threaded rod; and an inner wall of the threaded groove is matched with an outer wall of the threaded rod. According to the invention, by inserting a pen tail cap into one end of the pen body, an upper clamping block is clamped into an inner wall of an upper clamping groove, and a lower clamping block is clamped into an inner wall of a lower clamping groove, so that the pen tail cap is assembled; the pen body passes through the pen tail cap, so that the refill upper cover and the refill lower cover are installed and fixed; and assembling is convenient, and the assembling efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of capacitive pens, in particular to an active capacitive pen. Background technique [0002] A capacitive pen is a pen made of conductive materials with conductive properties and used to touch a capacitive screen to complete man-machine dialogue operations, including active capacitive pens and passive capacitive pens. Currently, it is often necessary to use a tablet computer for writing and drawing; However, the capacitive pens currently on the market have the following disadvantages: 1. Poor writing reliability. Due to the poor consistency of the relative positions of the pen tip and the signal transmitting antenna, the accuracy of the touch screen is prone to decline after long-term use. 2. The assembly efficiency is low and cannot Fast and accurate assembly, 3. Traditional finger writing has low writing accuracy and poor reliability for long-term use.
