Three first clamping strips for clamping are fixed to the right end of the inner wall of the anti-slip sleeve. A spring for providing clamping force is fixed to the inner arc surface of the threaded sleeve at the position of the first clamping strip. The other end of the spring is fixed to the end of the first clamping strip away from the axis of the anti-slip sleeve. A second clamping strip is fixed to the right end of the inner wall of the anti-slip sleeve. The left end face of the second clamping strip is located inside the left end face of the threaded sleeve. The three first clamping strips and one second clamping strip together clamp a replaceable cotton refill in the direction close to the axis of the anti-slip sleeve.

[0006] Preferably, a second housing is fixed to the right end of the anti-slip sleeve, a second retaining ring is fixed to the outer wall of the second housing, and a first pen tip is provided on the inner wall of the second housing. The left end of the first pen tip passes through the anti-slip sleeve and extends into the cotton pen refill.

[0007] Preferably, a first housing is fixed to the left end of the grip, a first retaining ring is fixed to the outer wall of the first housing, and a second pen tip is provided at the left end of the first housing.

[0008] Preferably, the inner wall of the first housing is fixed with a first clamping block that is evenly distributed in a circle, and the right end of the second pen tip extends through the first housing to the left side of the cotton pen refill.

[0009] Preferably, the outer wall of the first housing is fitted with a first pen cap, and the arc-shaped inner wall of the first pen cap is provided with a first groove, and the first retaining ring is adapted to the first groove.

[0010] Preferably, the outer wall of the second housing is fitted with a second pen cap, and the arc-shaped inner wall of the second pen cap is provided with a second groove.
