Description

Technical Field

[0001] The utility model relates to the field of writing tools, in particular to a soft pencil. Background Art

[0002] Pencils are one of the most commonly used writing tools, widely used in writing and drawing. Most common pencils on the market have a wooden outer shell and a graphite or colored lead core. They are lightweight, portable, and easy to write with and revise. However, pencils are typically sharpened to a very sharp point. For elementary school students, who are the primary users of pencils, these common pencils pose certain safety risks. Accidental injuries often occur due to inattention, playful play, or accidental collisions. Minor injuries may only be scratches or redness on the surface of the skin, while more serious injuries may cause skin damage, bleeding, or even deeper injuries. Therefore, pencil safety is a matter of concern.

[0003] In recent years, soft pencils with very soft pens have appeared on the market. The shape of the pencil can be changed and bent at will, which to a certain extent reduces the possibility of accidental injury caused by the sharp tip of the pencil, and to a certain extent ensures the safety of primary school students using pencils.

[0004] However, these soft pencils are difficult for elementary school students to hold for writing or drawing due to their excessively soft body, which can easily lead to fatigue and hinders their long-term use. Furthermore, to accommodate the softness of the body, the lead must also be soft, which results in a less pronounced pencil appearance. Furthermore, the pencils are only available in black and are not suitable for colored pencils. Furthermore, the soft body makes sharpening more difficult, making them inconvenient in practice. Few elementary school students actually use soft pencils as a regular writing tool.

[0005] Therefore, it is necessary to invent a soft pencil that is safe and easy to use. Utility Model Content

[0006] The utility model aims to provide a soft pencil for solving the problems of potential safety hazards in the use of existing common pencils, difficulty in writing or drawing with existing soft pencils, insufficient sharpness, difficulty in sharpening and poor practicality.

[0007] To achieve the above-mentioned object, the utility model provides a soft pencil, which includes a pen head and a pen holder, wherein the pen holder and the pen head are detachably connected, wherein the end of the pen holder close to the pen head is a first end, and the end of the pen holder away from the pen head is a second end; the first end is a holding portion made of a hard material, and the second end is made of a soft material; the pen head is a permanent pen head, which includes a pen tip and a protrusion, wherein the pen tip is fixedly connected to the protrusion, and the protrusion is detachably mounted to the first end of the pen holder, the pen tip is exposed from the pen holder, the pen tip is tapered, and the tip of the pen tip is arranged away from the pen holder.

[0008] As can be seen from the above scheme, the soft pencil provided by the present invention has a pen body comprising a first end made of a hard material and a second end made of a soft material. The hard material is a material with relatively high hardness that is not easily scratched or pressed into. Such a material can better maintain the stability of its shape and size when subjected to external forces, thereby ensuring a stable and unchanged appearance. During use, it is used as the holding portion of the pencil for holding and writing, and has a good supporting effect, does not affect the writing experience, and is no different from an ordinary wooden pencil; the soft material is a material with good softness and toughness, which can undergo a large deformation without breaking. Using the soft material as the second end makes the rear end of the pencil easy to deform, thereby preventing the user from accidentally injuring others due to the overall hardness of the pencil during chasing and playing. , has the advantage of high safety. In addition, the easily deformable second end can be bent or knotted at will, so that the entire pencil can be used for both writing and entertainment; the pen barrel and the pen tip are detachably connected, and the pencil can be replaced directly by replacing the pen tip without sharpening. The replacement is convenient and quick, and it also avoids the safety hazards caused by primary school students when sharpening pencils. The pen tip is a permanent pen tip. The permanent pen tip is a pen tip prepared by special alloy material treatment. After the pen tip comes into contact with the paper, it oxidizes instantly to achieve the effect of continuous writing. The color of the pen tip can be colored in addition to black. A pen barrel can be equipped with one or more pen tips, which saves space for carrying multiple pencils at the same time. It is more environmentally friendly and durable to use, non-toxic and harmless, and more suitable for primary school students.

[0009] A further solution is that a first groove extending toward the second end is provided at the first end of the pen barrel, and the protrusion is placed in the first groove.

[0010] As can be seen from the above solution, the arrangement of the first groove and the protrusion makes the soft pencil of the utility model not much different from common pencils in appearance, and users are more accustomed to using it. The arrangement of the first groove and the protrusion also makes it more convenient to replace the pen tip.

[0011] A further solution is that the pen tip is a cone, the diameter of the protrusion is smaller than the diameter of a side surface of the pen tip close to the protrusion, and the depth of the first groove is greater than or equal to the length of the protrusion.

[0012] As can be seen from the above solution, the above-mentioned setting of the diameter and length enables the pen tip to be placed more firmly in the pen holder, thereby ensuring the stability of writing.

[0013] A further solution is that the inner wall of the first groove is provided with an internal thread, and the outer wall of the protrusion is provided with an external thread, and the external thread matches the internal thread.

[0014] As can be seen from the above solution, the pen tip and the pen holder are connected by the internal and external threads, which is easy to operate and has a stable connection, further ensuring the stability of writing.

[0015] A further solution is that the length of the external thread is less than or equal to the length of the protrusion, and the external thread extends from an end of the protrusion away from the bottom surface of the first groove to an end close to the bottom surface of the first groove.

[0016] As can be seen from the above scheme, the length of the external thread is smaller than the length of the protrusion, and a blank area is reserved to facilitate alignment operation and tighten the pen tip, making operation easier.

[0017] A further solution is that a second groove extending away from the first groove is provided on a surface of the protrusion close to the first groove.

[0018] As can be seen from the above solution, the provision of the second groove reduces unnecessary loss of the nib material, thereby reducing the production cost of the soft pencil of the utility model.

[0019] A further solution is that the depth of the second groove is greater than or equal to the length of the protrusion.

[0020] It can be seen from the above solution that the provision of the second groove can reduce the manufacturing cost as much as possible while ensuring the normal service life of the soft pencil of the utility model.

[0021] A further solution is that the hard material is plastic.

[0022] As can be seen from the above scheme, the use of plastic to prepare the soft pencil of the utility model has low cost, long service life and is easy to manufacture.

[0023] A further solution is that the soft material is silicone.

[0024] As can be seen from the above scheme, the use of silica gel as the soft material to prepare the soft pencil of the utility model has low cost, safe use and simple preparation process.

[0025] A further solution is that the first end and the second end are connected to form a pen holder by gluing.

[0026] As can be seen from the above solution, the pen holder is formed by fixing the first end and the second end by gluing, which has a simple process, low operation requirements, and low preparation cost, and is suitable for widespread production. BRIEF DESCRIPTION OF THE DRAWINGS
