[0030] To enable those skilled in the art to better understand the solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] Example 1: As shown in the attached document Figure 1 and attached Figure 2 As shown, a pen includes a pen body 1, a pen clip 2, a writing component, and a mounting mechanism.

[0032] The pen body 1 includes a lower pen barrel 4 and an upper pen barrel 3. The lower pen barrel 4 is threaded onto the lower end of the upper pen barrel 3. A cap 5 is installed on the upper end of the upper pen barrel 3.

[0033] The writing assembly includes a pen refill 6, a pressing spring 7, a locking element 8, and a push button 9. The pen refill 6 is disposed within the pen body 1 and extends from the lower pen barrel 4 to the middle of the upper pen barrel 3. The pressing spring 7 is disposed between the lower end of the pen refill 6 and the lower pen barrel 4. The upper pen barrel 3 is provided with a sliding groove for the push button 9 to slide. The push button 9 includes an outer pushing part and an inner pushing part. The outer pushing part is located outside the pen body 1 for user operation, while the inner pushing part is located inside the pen body 1 to drive the pen refill 6. The outer pushing part and the inner pushing part are connected at the sliding groove. The locking element 8 is disposed between the inner pushing part of the push button 9 and the pen refill 6. The locking element 8 includes an upper moving part that can slide along the axial direction of the pen body 1 under the push of the inner pushing part of the push button 9, and a lower rotating part that is rotatably connected to the upper moving part through a set of inclined planes. The pen refill 6 is in contact with the lower rotating part.

[0034] The pen clip 2 is located on the outside of the pen body 1 and is used to hold books, papers, etc., thereby fixing the pen in the desired position. The mounting mechanism is used to rotate the pen clip 2 to the upper end of the pen body 1 and can lock the position when the pen clip 2 is rotated to a specified angle position.

[0035] The mounting mechanism includes a rotating shaft 10, n teeth 11, mn toothed grooves 12, and a reset drive 14. Where m and n are positive integers, and m≠1 when n=1. The rotating shaft 10 is mounted on the pen clip 2, meaning one end of the rotating shaft 10 is connected to the pen clip 2, and the axis of the rotating shaft 10 is perpendicular to the axis of the pen body 1. A through hole is provided on the upper pen barrel 3 of the pen body 1 for inserting the rotating shaft 10, so the other end of the rotating shaft 10 is inserted into the upper pen barrel 3 through this through hole. The teeth 11 are located on the outer periphery of the rotating shaft 10 and outside the pen body 1, while the toothed grooves 12 are located on the outer periphery of the through hole and opposite to the teeth 11. The position of the toothed grooves 12 corresponds to the required usage position of the pen clip 2. In this embodiment, four teeth 11 and four toothed grooves 12 are provided, with the four teeth 11 evenly distributed on the outer periphery of the rotating shaft 10 and the four toothed grooves 12 evenly distributed on the outer periphery of the through hole. A positioning ring 13 can be embedded around the outer periphery of the through hole, and a toothed groove 12 is formed on the positioning ring 13. The rotating shaft 10 includes a first shaft portion and a second shaft portion. The outer diameter of the first shaft portion is smaller than the diameter of the through hole, and at least a portion of the outer diameter of the second shaft portion is larger than the diameter of the through hole. An elastic adjustment groove is formed along the axial direction of the rotating shaft 10, which divides the second shaft portion into multiple parts and extends to the first shaft portion. In this embodiment, the second shaft portion is formed into a frustum shape, and the end with the larger outer diameter is connected to the first shaft portion to form a stepped surface. When the pen clip 2 is installed on the pen barrel 3, the second shaft portion is deformed inward by the elastic adjustment groove to temporarily reduce its outer diameter to pass through the through hole. After passing through the through hole, the second shaft portion returns to its original position, thereby fixing the pen clip 2. At this time, the teeth 11 are inserted into the toothed groove 12. A reset drive 14 is disposed inside the pen body 1 and connected to the rotating shaft 10 and the pen body 1 respectively. It is used to drive the tooth 11 and the tooth groove 12 to move closer together when the tooth 11 disengages from the tooth groove 12. In this embodiment, the reset drive 14 is a reset spring. The reset drive 14 is sleeved outside the first shaft portion and disposed between the second shaft portion and the pen body 1, and is limited by the stepped surface formed by the second shaft portion.

[0036] The mounting mechanism has a locked state and an unlocked state. In the locked state, the teeth 11 are engaged in the grooves 12, thereby fixing the angular position of the pen clip 2. In the unlocked state, the pen clip 2 moves away from the pen body 1 along the axis of the rotating shaft 10, the teeth 11 disengage from the grooves 12, the reset drive 14 is compressed, and the pen clip 2 can rotate relative to the pen body 1.

[0037] The process of rotating the pen clip 2 is as follows: the pen clip 2 is pulled outward from the pen body 1 along the axis of the rotating shaft 10, so that the teeth 11 disengage from the grooves 12, and the spring is compressed at the same time. After rotating the pen clip 2 to the desired angle, it is released. Under the action of the return spring, the teeth 11 fall back into the grooves 12 corresponding to the current position, that is, the pen clip 2 is locked.

[0038] Example 2: As shown in the attached document Figure 3 and attached Figure 3As shown, the difference between this embodiment two and embodiment one lies in the structure of the installation structure.

[0039] The mounting mechanism includes a rotating shaft 10, n teeth 11, mn toothed grooves 12, and a reset drive 14. Where m and n are positive integers, and m ≠ 1 when n = 1. The rotating shaft 10 is mounted on the pen clip 2, meaning one end of the rotating shaft 10 is connected to the pen clip 2, and the axis of the rotating shaft 10 is perpendicular to the axis of the pen body 1. A through hole is provided on the upper pen barrel 3 of the pen body 1 for the rotating shaft 10 to be inserted, so the other end of the rotating shaft 10 is inserted into the upper pen barrel 3 through this through hole. The toothed grooves 12 are located on the rotating shaft 10 and within the pen body 1, while the teeth 11 are located on the reset elastic member. In this embodiment, the rotating shaft 10 includes a first shaft portion and a second shaft portion. The outer diameter of the first shaft portion is smaller than the diameter of the through hole, and the outer diameter of the second shaft portion is larger than the diameter of the through hole. The end face of the second shaft portion forms the toothed grooves 12. The reset elastic element is connected to and located inside the pen body 1. In this embodiment, the reset drive element 14 is integrated with the cap 5. It is made of elastic material and can deform under force and return to its original shape when no force is applied. The reset drive element 14 extends downward along the axial direction of the pen body 1 from the inner side of the cap 5. It has a groove for accommodating the end of the rotating shaft 10, and a tooth 11 is disposed in the groove. In this embodiment, one tooth 11 (tooth platform) is disposed in the groove, and four tooth grooves 12 are formed on the end face of the second shaft portion of the rotating shaft 10.

[0040] The mounting mechanism also has a locked state and an unlocked state. In the locked state, the teeth 11 are engaged in the grooves 12. In the unlocked state, the pen clip 2 rotates, which pushes the reset drive 14 to deform and cause the teeth 11 to disengage from the grooves 12, allowing the pen clip 2 to rotate relative to the pen body 1.

[0041] The pen clip 2 rotates as follows: Forcefully rotating the pen clip 2 causes the rotating shaft 10 to rotate synchronously. The protruding portion between two adjacent toothed grooves 12 at the end of the rotating shaft 10 pushes the reset drive member 14 to deform, thereby disengaging the tooth 11 from the toothed groove 12. When the pen clip 2 rotates at an angle until the next toothed groove 12 aligns with the tooth 11, the elastic deformation of the reset elastic member presses the tooth 11 back into the toothed groove 12, thus locking the pen clip 2.

[0042] In all the embodiments above, the pen clip 2 is an independent clip, meaning it can clamp the pen on its own without relying on the pen body 1. (See attached...) Figure 5 and attached Figure 6 As shown, the pen clip 2 includes two clips, one end of which is fixedly connected, roughly forming an inverted U-shape. The lower ends of the clips can separate and change shape under external force, and the two clips can clamp paper, etc.

[0043] In the above embodiments, the angle positions at which the pen clips 2 can be fixed can be designed as needed. For example, consider setting four fixed angle positions for the pen clips 2.

[0044] 1. First state: Pen clip at 20°. (See attached image) Figure 7 As shown, the length direction of the pen clip 2 is parallel to the length direction of the pen body 1 at this time. The pen clip 2 is positioned at the edge of the notebook 15 as shown in the attached figure. Figure 11 As shown.

[0045] 2. Second state: Pen clip at 245°. (See attached image) Figure 8 As shown, the pen clip 2 rotates clockwise relative to the pen body 1 in its first state until the angle between them is 45°. The pen clip 2 is then positioned at the edge of the notebook 15 as shown in the attached figure. Figure 12 As shown.

[0046] 3. Third state: Pen clip 2 rotated 90° clockwise. (See attached image) Figure 9 As shown, the pen clip 2 rotates clockwise relative to the pen body 1 in its first state until the angle between them is 90°. The pen clip 2 is then positioned at the edge of the notebook 15 as shown in the attached diagram. Figure 13 and attached Figure 14 As shown.

[0047] 4. Fourth state: Pen clip 2 rotated 90° counterclockwise. (See attached image) Figure 10 As shown, at this time, the pen clip 2 rotates counterclockwise relative to the pen body 1 in the first state until the angle between the two is 90°.

[0048] The rotatable and positionable pen clip 2 design improves the pen's flexibility, enabling it to adapt to different usage conditions and bringing convenience to the user.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
