[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] according to Figures 1 to 6A multi-head rotating pen comprises a pen cover 1, a pen body 2, a rotating structure 3, a refill ring 4 with a variety of refills, and a pen pusher 5. The pen body 2 is fixedly connected to the pen cover 1, and a rotating structure 3 and a pen pusher 5 are arranged in the pen body 2. The refill ring 4 is fixed at the bottom of the rotating structure 3, and the pen pusher 5 is arranged in a pushing cavity 8 of the pen body 1. The improvement is that a rotating ball structure 6 is provided on the pen body 1 to cooperate with the rotating structure 3 to realize blind selection of refills 7 of different colors to be rotated and aligned with the pushing cavity 8, and then pushed out by the pen pusher 5, and the rotating ball structure 6 and the pen pusher 5 are on the same vertical plane.

[0027] The middle part of the pen body 2 is provided with a partition plate to divide it into a front section and a rear section. The upper rear section of the pen body 2 is provided with a push cavity 8, and a guide hole 25 is opened on the surface of the push cavity 8. A push pen rod 5 is slidably fixed in the push cavity 8, and the push portion of the push pen rod 5 extends out of the guide hole 25 for easy operation. A cap 22 is fixed on the top of the pen body 2, and the cap 22 is connected and fixed with the push cavity 8 to prevent the push pen rod 5 from escaping from the push cavity 8. An elastic spring 9 is sleeved on the outer wall of the push pen rod 5 to always maintain an outward pushing force. The front end of the push cavity 8 is provided with a push hole 10 on the partition plate, and the size of the front end of the push pen rod 6 matches it, so that when the user pushes the push pen rod 6, the front end of the push pen rod 6 will be pushed out from the push hole 10, thereby pushing the pen core 7 to protrude in front of the pen cover 1. The front section of the pen body 2 is fixed with a limit rod 11 at the bottom center of the partition plate, and a guide piece 12 is fixed between the limit rod 11 and the push hole 10. The pen core 7 on the guide piece 12 is naturally aligned with the push hole 10 at the front end of the push cavity 8, and the pen shaft 5 will be pushed out of the pen cover 1. The rear part of the guide piece 12 has a locking block 26 that cooperates with the pen core 7. After the pen core 7 is withdrawn, it is slightly retreated and pressed against the locking block 26 to achieve self-locking.

[0028] The rotating structure 3 includes a hollow rotating wheel 13, a fixing hole 14 is provided at the center of the hollow rotating wheel 13, the fixing hole 14 matches the size of the limiting rod 11 and the hollow rotating wheel can be rotatably fixed in the limiting rod 11, and a plurality of refill bins 15 are distributed along the circumference with the fixing hole 14 as the center, and the refill bin 15 is a cylindrical cavity, and the periphery near the center has a cut edge to form a gap 23, which cooperates with the guide piece 12 to form an integral refill cavity for positioning the refill 7, and the refill bin 15 is arranged with respective refills 7, and a refill ring 4 is fixed to the bottom of the refill bin 15, and a spring 16 is sleeved on the outer wall of the refill 7 to maintain a certain thrust so that it can be retracted and reset.

[0029] The inner wall of the pen cover 1 is provided with a thread groove 17, and the outer wall of the corresponding pen body 2 is provided with a thread 18 to achieve screwing and fixing. In order to improve the rotation flexibility, a rotating sleeve 25 is sleeved on the outer side of the hollow rotating wheel 13, and the hollow rotating wheel 13 is arranged in the pen body 2 through the rotating sleeve 25.

[0030] The rotating ball structure 6 includes a rotating ball chamber 19, in which a rotating ball 20 is fixed. A fixing ring 21 is fixed on the top of the rotating ball chamber 19 to prevent the rotating ball 20 from falling out and provide a better hand feel when the user rotates. The rotating ball 20 is in friction contact with the surface of the hollow rotating wheel 13 through the rotating sleeve 25. When the rotating ball 20 rotates left and right, it drives the hollow rotating wheel 13 to rotate left and right, thereby driving the refill bin 15 to rotate left and right. In this way, the refills 7 of different colors in the refill bin 15 can be randomly selected to align with the push hole 10 at the front end of the push cavity 8 similar to blind selection.

[0031] When the user uses the product, he only needs to manually rotate the rotating ball 20 in the rotating ball chamber 19, and the rotating ball 20 drives the refill bin 15 to rotate around the fixing hole 14, so that the refills 7 of different colors enter the guide sheet 23, and the user pushes the push pen rod 5 to push the refill aligned with the push cavity 8 out of the pen cover 1.
