Technical Field

[0001] The present invention relates to the technical field of capacitive pens, and in particular to a simulated capacitive pen assembly and a simulated capacitive pen. Background Art

[0002] Capacitive pen is a pen made of conductive material with conductive properties, used to touch the capacitive screen to complete human-computer interaction. The capacitive pen is an auxiliary device that imitates the human body (usually fingers) to complete human-computer interaction through conductive materials. With the development of APP, the current capacitive pen is no longer a simple replacement for finger operation. More and more professionals have tried to use active capacitive pens to work on mobile devices. The capacitive pen refill is a part of the capacitive pen.

[0003] With the development of technology, tablets and electronic pens have gradually replaced traditional paper and pens. Although there are many capacitive pens on the market, since tablets and pens are basically made of glass and plastic, these capacitive pens cannot bring the feeling of real paper and pen to users, which makes users who are accustomed to writing with paper and pen find it difficult to accept. However, they have to use them in some scenarios and can only make do with them. However, because the tactile feel is lost, it is difficult to restore the user's original writing level, which makes users feel regretful. Summary of the invention

[0013] Furthermore, the invention also comprises a pen tube, one end of which is sleeved with the pen tip, and a main bracket is arranged in the pen tube.

[0014] Furthermore, it also includes a magnet, which is arranged on the main bracket.
