Description

Technical Field

[0001] This utility model relates to a pencil, specifically a pencil with an adjustable extended cap. Background Technology

[0002] Pencils are common school supplies, and current wooden pencils are still sharpened to a point. After being sharpened multiple times, pencils tend to shorten, making them difficult to grip and write with. While pencils with extended caps are available, their caps are fixed at the end and cannot be adjusted. Users cannot achieve the desired extension with a single cap; instead, they must stack more caps at the end or purchase a suitable pencil extender separately. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the present invention aims to provide a pencil with an adjustable extended cap.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pencil with an adjustable extension cap includes a barrel and a lead, and further includes a threaded sleeve and a cap. The threaded sleeve wraps around the outer surface of the barrel, and the outer surface of the threaded sleeve has an external thread. The inner cavity of the cap has an internal thread that matches the external thread. When the cap is fitted onto the head or tail of the barrel, the internal thread of the cap engages with the external thread of the threaded sleeve.

[0006] Furthermore, the threaded sleeve includes a silicone portion and a hard plastic portion, the hard plastic portion being located at the tail of the threaded sleeve.

[0007] Furthermore, the silicone portion and the hard plastic portion are integrally molded.

[0008] Furthermore, the pen barrel is made of wood.

[0009] The beneficial effects of this utility model are as follows: In this utility model, by adding a threaded outer sleeve with external threads to the outside of the pen barrel and configuring a matching internal thread in the inner cavity of the pen cap, the pen cap, when used as an extender on the end of the pen barrel, can be rotated axially and stopped at any position, thereby allowing the position of the pen cap to be adjusted to meet different extension needs of users.

[0015] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0016] This embodiment provides a pencil with an adjustable, extended cap, such as... Figure 1-5 As shown, like a traditional pencil, it includes a barrel 1 and a lead 2. The barrel 1 is usually made of wood.

[0017] In this embodiment, the pencil with an adjustable extension cap further includes a threaded outer sleeve 3 and a cap 4. The threaded outer sleeve 3 wraps around the outer surface of the pencil barrel 1, and the outer surface of the threaded outer sleeve 3 has an external thread. The inner cavity of the cap 4 has an internal thread 41, which matches the external thread. When the cap 4 is fitted onto the head or tail of the pencil barrel 1, the internal thread inside the cap 4 engages with the external thread of the threaded outer sleeve 3.

[0018] When not using the pencil, attach the cap 4 to the head of the pencil barrel, as shown. Figure 3 As shown, the pen cap 4 can be fixed to the head of the pen barrel by the internal thread of the pen cap 4 engaging with the external thread of the threaded sleeve 3. When using a pencil, if it is necessary to use the pen cap 4 as an extender to lengthen the pen barrel, the pen cap 4 is placed on the end of the pen barrel 1, as shown. Figure 4-5 As shown, the internal thread of the pen cap 4 engages with the external thread at the tail of the threaded sleeve 3. When the position of the pen cap 4 needs to be adjusted to meet different extension requirements, rotate the pen cap 4. Through the engagement of the internal and external threads, the pen cap 4 can move axially along the threaded sleeve 3 and stop at any position. Additionally, children and beginners can use the indentations between the threads on the threaded sleeve to position their fingers, thus finding the correct pen-holding position more quickly and mastering the correct pen-holding posture.

[0019] Furthermore, in this embodiment, the threaded sleeve 3 includes a silicone portion 31 and a hard plastic portion 32, with the hard plastic portion 32 located at the tail of the threaded sleeve 3. The purpose of using the silicone portion as the main body of the threaded sleeve is to utilize the friction of silicone to help the pen cap stay more securely in any position on the threaded sleeve. The tail of the threaded sleeve is set as a hard plastic portion because silicone is relatively soft; when the pen cap and silicone portion are combined, the pen cap may wobble due to deformation of the silicone under force when gripping the pen, affecting grip. By setting the tail of the threaded sleeve as a hard plastic portion, when the pen cap is fitted onto the tail of the pen barrel, it first engages with the external threads of the hard plastic portion, and then with the external threads of the silicone portion. The hard plastic portion helps the pen cap remain stable and prevent wobble under force. Additionally, silicone can also improve the comfort of gripping the pen.

[0020] Furthermore, in this embodiment, the silicone portion 31 and the hard plastic portion 32 are integrally molded. Specifically, the integral molding of the silicone portion and the hard plastic portion can be achieved through a two-material injection molding process.

[0021] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
