Abstract: A replaceable touch pen is provided with an electro-conductive barrel, the front end of the electro-conductive barrel is connected with an annular fixing member. The fixing member is locked at the front end of the electro-conductive barrel by snapping or screwing. The other end of the fixing member locks an electro-conductive nib through a tight-fitting method. The electro-conductive nib is an elastic material and can avoid the damage to an electronic device by an inappropriate force when a user is operating the touch pen. When the electro-conductive nib is worn out, broken or is to be replaced by a nib of a different size, the fixing member can be dismantled to rapidly and easily replace the electro-conductive nib at any time.
