Fig. 1 to 7 show a rotary pen according to the spirit of the present invention, which includes a pen core 1, a rotary part 2, an adjustment part 3, and a main body part 4.

Specifically, the pen core 1 has a writing tip 11 and a fixed tip 12 corresponding to the writing tip 11. The type of the cartridge 1 is not limited, and the cartridge 1 may be a pencil cartridge, a carbon cartridge, or the like, for example.

The rotary part 2 includes a knob 21 and a driving body 22 extended from the knob. In this embodiment, the driving body 22 can integrally extend from the knob 21, that is, the knob 21 and the driving body 22 are a unitary structure. Alternatively, in other embodiments, the driving body 22 and the knob 21 are separately manufactured, and one end of the driving body 22 is mounted to the knob 21 such that the driving body 22 extends to the knob 21.

The adjusting portion 3 includes an adjusting body 31 and at least one sliding body 32, and the sliding body 32 is spiral and protrudes from the outer wall of the adjusting body 31. Preferably, the number of the sliding bodies 32 is two, and two sliding bodies 32 are respectively disposed at two opposite ends of the adjusting body 31, that is, one end of the adjusting body 31 is provided with one sliding body 32, and the other end of the adjusting body 31 is provided with one sliding body 32.

The main body 4 has a first end 41, a second end 42, an adjustment space 43, a sliding groove 44, a first port 45 and a second port 46, the first end 41 and the second end 42 correspond to each other to define the length dimension of the main body 4, the sliding groove 44 in a spiral shape communicates with the adjustment space 43 and extends between the first end 41 and the second end 42, the first port 45 communicates with the adjustment space 43 at the first end 41, and the second port 46 communicates with the adjustment space 43 at the second end 42.

The fixed end portion 12 of the pen core 1 is detachably mounted to the adjusting body 31, the adjusting portion 3 is movably mounted to the adjusting space 43 of the body 4 from the first port 45 of the body 4 in such a manner that the sliding body 32 slidably maintains the sliding groove 44 of the body 4, so as to allow the adjusting portion 3 to reciprocate in the adjusting space 43 of the main body portion 4 to drive the pen core 1 so that the writing end portion 11 of the pen core 1 extends out of the adjusting space 43 through the second port 46 of the main body portion 4, the drive body 22 of the rotating portion 2 extends from the first port 45 of the main body portion 4 into the adjustment space 43 of the main body portion 4 and further extends in the direction of the second port 46 in such a manner that the adjustment portion 3 is drivably connected to the drive body 22, and the knob 21 is held at the first end portion 41 of the main body portion 4.

Before the rotary pen is used, when the knob 21 of the rotating portion 2 is driven to rotate in one direction relative to the main body portion 4, the knob 21 of the rotating portion 2 drives the driving body 22 of the rotating portion 2 to synchronously rotate in the adjusting space 43 of the main body portion 4, at this time, the driving body 22 drives the adjusting portion 3 to synchronously rotate in the adjusting space 43 of the main body portion 4 to allow the adjusting portion 3 to move from the first end portion 41 to the second end portion 42 of the main body portion 4 under the mutual matching of the sliding body 32 of the adjusting portion 3 and the sliding groove 44 of the main body portion 4, and at this time, the adjusting portion 3 drives the pen core 1 to extend the writing end portion 11 of the pen core 1 out of the adjusting space 43 from the second end portion 46 of the main body portion 4.

After the rotary pen is used, when the knob 21 of the rotating portion 2 is driven to rotate in the opposite direction relative to the main body portion 4, the knob 21 of the rotating portion 2 drives the driving body 22 of the rotating portion 2 to synchronously rotate in the adjusting space 43 of the main body portion 4, at this time, the driving body 22 drives the adjusting portion 3 to synchronously rotate in the adjusting space 43 of the main body portion 4, so that the sliding body 32 of the adjusting portion 3 and the sliding groove 44 of the main body portion 4 are matched with each other to allow the adjusting portion 3 to move towards the first end portion 41 of the main body portion 4, at this time, the adjusting portion 3 drives the pen core 1 to hide the writing end portion 11 of the pen core 1 from the second end opening 46 of the main body portion 4 in the adjusting space 43, so as to prevent the pen core 1 from contacting other objects to cause pollution.

When the refill 1 needs to be replaced, the rotating portion 2 can be pulled out by applying a force in a direction away from the main body portion 4, at this time, the adjusting portion 3 is detached from the main body portion 4 along with the rotating portion 2, a new fixed end portion 12 of the refill 1 is then installed on the adjusting portion, and then the adjusting portion 3 and the rotating portion 2 are installed on the main body portion 4 at the same time at the first port 45 of the main body portion 4 after the adjusting portion 3 and the rotating portion 2 are assembled.
