A rubber sleeve is arranged on the outer wall of the protective sleeve 4, which can make the hands more comfortable when rotating the protective sleeve 4. Anti-skid lines are formed on the rubber sleeve, which can increase the friction between the hands and the protective sleeve 4, thereby effectively preventing the hands from slipping when rotating the protective sleeve 4. A moving block 5 is slidably connected to the outer wall of the pen barrel 1. A T-shaped block 6 is fixedly connected to the bottom of the moving block 5. A T-shaped groove 7 matching the T-shaped block 6 is formed in the outer wall of the pen barrel 1, which can effectively limit and guide the moving block 5, thereby making the moving block 5 more stable when sliding on the pen barrel 1. A plurality of balls 19 are rotatably connected to the bottom of the T-shaped block 6 on both sides, which are linearly and equidistantly arranged on the T-shaped block 6, thereby effectively reducing the friction between the T-shaped block 6 and the inner wall of the T-shaped groove 7, making it easier and more labor-saving for people to slide the moving block 5. A magnet 15 is fixedly connected to one side of the inner wall of the T-shaped groove 7. An iron sheet 16 is fixedly connected to one side of the T-shaped block 6 and is attracted to the magnet 15. The iron sheet 16 on one side of the T-shaped block 6 is attracted to the magnet 15 on one side of the inner wall of the T-shaped groove 7, which can fix the moving block 5 to a certain extent. A limiting assembly is arranged at the bottom of the inner wall of the T-shaped groove 7. A limiting block 8 is fixedly connected to one end of the moving block 5 close to the protective sleeve 4. Symmetrical fixed blocks 9 are fixedly connected to the outer wall of the protective sleeve 4, and the distance between the two fixed blocks 9 is the same as the width of the limiting block 8.
