With the above arrangement, when the first head 201 is directed downward, water in the gap formed by the second boss 32 and the second seal groove 2011 is easily discharged.

It will be appreciated that the stylus may be in a state in which the first head 201 is vertically down or inclined down during use, and the stylus may be in a flat state during placement, where the first head 201 and the first shaft 202 may be in the same horizontal plane.

In this embodiment, an end of the first head 201 near the first shaft 202 extends outward to form a second waterproof step 2014, and in the axial direction of the first shaft 202, the projected outer contour of the second waterproof step 2014 is located outside the projected outer contour of the first head 201. That is, the second waterproof step 2014 is provided between the first head 201 and the first shaft 202, and an end of the first head 201 adjacent to the first shaft 202 is extended outwardly in a radial direction thereof to form an end of the first head 201 adjacent to the first shaft 202, so that an outer diameter of the second waterproof step 2014 is larger than a maximum outer diameter of the first head 201, and more particularly, as shown in fig. 5, since the second seal groove 2011 is located under the second waterproof step 2014, both sides of the second waterproof step 2014 are the second side wall 2013 and the third side wall 2015, respectively, and an outer edge of the third side wall 2015 relatively protrudes from an outer edge of the first side wall 2012 in a radial direction of the cartridge 2. In other words, in the radial direction of the cartridge 2, the third side wall 2015 is higher than the first side wall 2012, and the height difference H therebetween is greater than zero. By the arrangement of the third side wall 2015 in the second waterproof step 2014, water is prevented from entering the inside of the pen body 1 through the gap between the elastic sleeve body 3 and the pen core member 2 in a state where the stylus pen is horizontally placed.

In this embodiment, the distance L between the connecting surface of the first head 201 and the first shaft 202 and the pen body 1 is 0.2mm to 1mm. At least the first head 201 is made of plastic, and when the writing-core member 2 moves to the final position, the first head 201 abuts against the pen body 1 to play a role of buffering.

Wherein, the second pen core body 21 may be stainless steel. Because the wear resistance of the plastic material is good, the abrasion of the second pen refill body 21 to the pen body 1 can be effectively reduced, and the service life of the touch pen is prolonged. In an embodiment, the protection member 22 and the second pen core body 21 are made of plastic.

Further, the inner diameter dimension of the shield cylinder 222 is smaller than the inner diameter dimension of the mounting cavity 2210. This arrangement allows the second head 211 to be easily snapped into the mounting cavity 2210. At least a portion of the sidewall of the second shaft 212 protrudes outward to form a stop 2121, and an end of the shield cylinder 222 remote from the shield head 221 abuts the stop 2121. With the above arrangement, relative movement between the protective cylinder 222 and the second cartridge body 21 is avoided in the axial direction of the second cartridge body 21, so that the transmission of force is more accurate in the use process of the stylus pen.

The distance L between the connecting surface of the protective head 221 and the protective barrel 222 and the pen body 1 is 0.2mm-1mm. Wherein, the protection head 221 is made of plastic material, and when the pen core 2 moves to the final position, the protection head 221 is abutted to the pen body 1 to play a role of buffering.
