A pressure cap is provided between the pull rod and the rotating shaft to prevent the pull rod from escaping from the first cavity, and the pressure cap is engaged with the rotating shaft. A movable rod is provided inside the rotating shaft, and one end of the movable rod abuts against the end of the pen core away from the elastic member. Straight ribs that slide with the straight grooves are provided on the movable rod, and the number of straight ribs is the same as the number of straight grooves. Each spiral track abuts against a corresponding straight rib.

[0005] Preferably, the collar is provided with a notch for facilitating the user to rotate the pull rod.

[0006] Preferably, an anti-slip portion is provided on the peripheral side surface of the pull rod.

[0007] Preferably, the anti-slip portion includes a plurality of anti-slip protrusions.

[0008] Preferably, the elastic member is a spring.

[0009] The beneficial effects of the utility model are as follows: the utility model drives the movable rod to move downward by rotating the pull rod to push the pen tip at one end of the pen core out of the pen shaft, or retracts the pen tip into the pen shaft by pushing the elastic device, thereby realizing the extension and retraction of the pen tip with a brand-new structure.

[0018] like Figures 1-8 As shown, a draw rod painting pen comprises a pen body 1, a pen core 2 arranged inside the pen body 1, and a pen tip 3 arranged at one end of the pen core 2. The end of the pen core 2 close to the pen tip 3 is sleeved with an elastic member 4 that abuts against one end of the pen body 1. The end of the pen body 1 away from the elastic member 4 is connected to a collar 5. A first cavity 6 is provided in the collar 5. A hollow rotating shaft 7 is provided inside the first cavity 6. A plurality of straight grooves 8 are provided on the circumferential side of the rotating shaft 7. A draw rod 9 that can rotate around the rotating shaft 7 is rotatably connected between the inner wall of the first cavity 6 and the rotating shaft 7. The draw rod 9 is a hollow structure, and its inner wall is provided with There are the same number of spiral tracks 10 as the straight grooves 8, and a slot 11 is provided at one end of at least one spiral track 10. A pressure cap 12 is provided between the pull rod 9 and the rotating shaft 7 to prevent the pull rod 9 from escaping from the first cavity 6. The pressure cap 12 is engaged with the rotating shaft 7. A movable rod 13 is provided inside the rotating shaft 7, and one end of the movable rod 13 abuts against the end of the refill 2 away from the elastic member 4. A straight rib 14 is provided on the movable rod 13 for sliding cooperation with the straight groove 8, and the number of the straight rib 14 is the same as the number of the straight grooves 8. Each spiral track 10 abuts against a corresponding straight rib 14.

[0019] The collar 5 is provided with a notch 15 for facilitating the user to rotate the pull rod 9 .

[0020] An anti-slip portion is provided on the peripheral side surface of the pull rod 9.

[0021] The anti-slip portion includes a plurality of anti-slip protrusions.

[0022] The elastic member 4 is a spring.

[0023] Preferably, a pull-out drawing pen comprises a pen body 1, a refill 2 arranged inside the pen body 1, and a pen tip 3 arranged at one end of the refill 2. The end of the refill 2 close to the pen tip 3 is provided with a spring that abuts against one end of the pen body 1. The end of the pen body 1 away from the spring is connected with a collar 5. A first cavity 6 is provided in the collar 5. A hollow rotating shaft 7 is provided inside the first cavity 6. Two straight grooves 8 are provided on the circumferential side of the rotating shaft 7. A pull-out rod 9 that can rotate around the rotating shaft 7 is rotatably connected between the inner wall of the first cavity 6 and the rotating shaft 7. The pull-out rod 9 is central. Empty structure, its inner wall is provided with two spiral tracks 10, one end of at least one spiral track 10 is provided with a slot 11, a pressure cap 12 is provided between the pull rod 9 and the rotating shaft 7 to prevent the pull rod 9 from escaping from the first cavity 6, the pressure cap 12 is engaged with the rotating shaft 7, a movable rod 13 is provided inside the rotating shaft 7, one end of the movable rod 13 abuts against the end of the pen core 2 away from the spring, and the movable rod 13 is provided with two straight ribs 14 respectively sliding with any straight slot 8, and each spiral track 10 abuts against a corresponding straight rib 14.

[0024] Working principle:

[0025] When in use, first rotate the pull rod 9, and the spiral track 10 inside the pull rod 9 pushes the straight rib 14 of the movable rod 13 downward. At this time, the straight rib 14 slides downward in the straight groove 8 in the rotating shaft 7, and the movable rod 13 drives the pen core 2 to move downward. When at least one straight rib 14 is inserted into the slot 11 provided at one end of the spiral track 10, the pen head 3 provided at one end of the pen core 2 is exposed from the pen shaft 1, and writing can be carried out.

[0026] When the pen is not in use, the user first rotates the pull rod 9 in the opposite direction. Under the push of the elastic member 4 which is provided on the end of the pen core 2 close to the pen tip 3 and abuts against one end of the pen barrel 1, the pen core 2 moves upward, driving the movable rod 13 to move upward. The straight rib 14 of the movable rod 13 slides upward along the straight groove 8 in the rotating shaft 7, and the movable rod 13 returns to its original position, and the pen tip 3 retracts into the pen barrel 1.
