[0029] The driving sleeve 8 includes a guiding sleeve 81, a sliding claw sleeve 82, and a docking sleeve 83 which are sequentially arranged and communicated. A stepped surface 801 is formed between the inner wall of the docking sleeve 83 and the inner wall of the sliding claw sleeve 82. The top end of the refill 4 abuts against the stepped surface 801. The guiding sleeve 81 is slidably and rotatably connected to the inner wall of the pen barrel 1. A plurality of patterns 811 are provided on the outer wall of the guiding sleeve 81. The plurality of patterns 811 are spaced apart and arranged in a staggered manner along the circumferential direction of the guiding sleeve 81. The sliding claw sleeve 82 is slidably and rotatably connected to the inner wall of the pen sleeve 3. The docking sleeve 83 is slidably and rotatably connected to the inner wall of the push rod sleeve 72. A first tooth column ring 822 is formed on the side wall of the sliding claw sleeve 82 close to the docking sleeve 83. A second tooth column ring 722 is formed on the end surface of the push rod sleeve 72. The teeth of the first tooth column ring 822 and the second tooth column ring 722 are both helical teeth.

[0030] Preferably, a ramp groove 7112 is formed at the bottom of the arc-shaped plate 711, and an inclined surface 7113 matching the ramp groove 7112 is formed at a position of the bottom of the arc-shaped plate 711 close to the track space 7114. Three guiding strips 821 are uniformly distributed on the outer wall of the sliding claw sleeve 82 in an annular array. The guiding strips 821 are slidably connected to the track space 7114, or the top ends of the guiding strips 821 abut against the inner wall of the ramp groove 7112 to make the guide rail member 71 adapt to the sliding claw sleeve 82.

[0031] When the user uses this ballpoint pen, the user presses on the pressing pen cap 9 to overcome the downward movement of the second elastic member 73. The push rod sleeve 72 drives the sliding claw sleeve 82 to move downward, so that the driving sleeve 8 drives the pen refill 4 to compress the first elastic member 6 and move downward. The pattern 811 on the guide sleeve 81 is misaligned with the display slot 101. Until the sliding claw sleeve 82 moves downward to the position where the guide strip 821 is separated from the guide rail member 71, the inclined teeth of the first tooth column ring 822 cooperate with the inclined teeth of the second tooth column ring 722, so that the sliding claw sleeve 82 rotates relative to the guide rail member 71 to the position where the guide strip 821 corresponds to the ramp groove 7112 on the arc plate 711 or the guide strip 821 corresponds to the inclined surface 7113. After that, the user releases the pressing pen cap 9, the second elastic member 73 recovers its deformation and drives the pressing pen cap 9 and the push rod sleeve 72 to move upward and reset, and the first elastic member 6 recovers its deformation and drives the pen refill 4 and the driving sleeve 8 to move upward and reset;

[0032] When the guide strip 821 corresponds to the ramp groove 7112, the guide strip 821 slides along the inner wall of the ramp groove 7112 under the action of the first elastic member 6, so that the driving sleeve 8 rotates and moves upward relative to the guide rail member 71. Until the driving sleeve 8 rotates relative to the pen barrel 1 to the position where the top end of the guide strip 821 abuts against the inner wall of the ramp groove 7112, the height position of the sliding claw sleeve 82 is restricted by each ramp groove 7112, and the pen refill 4 extends out of the pen tip 2 for the user to use this ballpoint pen for writing. The corresponding pattern 811 of the guide sleeve 81 matches the display slot 101 for the user to view;

[0033] When the guide strip 821 corresponds to the inclined surface 7113, the guide strip 821 slides along the inclined surface 7113 under the action of the first elastic member 6, so that the driving sleeve 8 rotates and moves upward relative to the guide rail member 71. Until the driving sleeve 8 rotates relative to the pen barrel 1 to the position where the guide strip 821 corresponds to the track space 7114, the sliding claw member moves upward to the position where it abuts against the push rod sleeve 72 under the guidance of each track space 7114. The height position of the sliding claw sleeve 82 is restricted by the second tooth column ring 722 of the push rod sleeve 72, and the pen refill 4 extends into the pen tip 2. The corresponding pattern 811 of the guide sleeve 81 matches the display slot 101 for the user to view.

[0034] The pressing pen cap 9 of this ballpoint pen drives the pen refill 4 to extend or retract through the telescopic locking mechanism 7, realizing the pressing type telescopic of the pen refill 4. During this process, the driving sleeve 8 rotates relative to the pen barrel 1 to the position where the pattern 811 matches the display slot 101, so that the pattern 811 of the display slot 101 is switched when the cylinder pen is pressed, improving the visual effect of this ballpoint pen, having better fun and improving the user experience of this ballpoint pen.

[0035] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
