Thereby, the guide part can be used for the positioning of the tool. When scraping off the residual glue, the tool traces through the guide part without deflection, so as to ensure that the inner peripheral edge of the receiving groove will not be damaged and skewed. Or the case of reaming.

Description

Pen holder of writing brush and cutter used in the pen holder

The present invention relates to a pen holder of a writing brush, and more particularly to a pen holder which needs to remove residual glue to replace a pen tip and a cutter used in the pen holder.

According to the press, the brush is one of the traditional writing tools, while calligraphy shows the heritage of text art and culture through the writing of the brush.

The writing brush can be divided into two parts: the writing brush shaft and the pen tip. Due to the different writing postures of each person and the difference in the preservation method after cleaning, the pen tip may be worn and must be replaced, otherwise it will affect the writing Performance.

However, for generally cheap brushes, when the tip of the pen is bifurcated or damaged and cannot be written normally, the entire brush is usually discarded directly, and a new brush is purchased; however, for expensive brushes, Or for writing brushes that are collectible and commemorative, the user will use the method of replacing the new pen tip to re-enable the normal writing function of the brush to achieve the purpose of permanent use and storage. At this time, the pen tip is a consumable, so In this case, replacing the nib is an important issue.

Please refer to FIG. 1A to FIG. 1D, which are schematic diagrams of a conventional writing brush replacement process. Generally speaking, the writing brush rod 2 of the writing brush 1 has a receiving slot 3, so that the writing tip 4 is glued to the receiving slot 3. When the pen tip 4 is to be replaced, as shown in FIG. 1B, after the pen tip 4 is detached from the brush shaft 2, the hole wall of the receiving groove 3 is easily damaged. Residual glue 5 is left, and then as shown in FIG. 1C, a general user will use the blade 6 to reach into the accommodating groove 3 to scrape off the residual glue 5, so as to subsequently adhere a new pen tip 4 to the accommodating groove 3.

However, in the process of scraping off the adhesive residue 5 by the blade 6, due to improper application of force or a wrong method, it is easy to cause the receiving groove 3 to expand or distort, as shown in FIG. 1D. As a result, When the new nib 4 is stuck in the accommodating groove 3, the gap 7 between the nib 4 and its inner wall due to the reaming of the accommodating groove 3 will reduce the adhesion of the new nib 4 and affect the writing performance. The reaming of the groove 3 makes the wall of the hole thinner, which easily causes the writing brush rod 2 to be easily damaged; or if the receiving groove 3 is skewed, the pen tip 4 cannot be aligned with the center of the writing brush rod 2 and deviates. In addition to affecting the writing performance of the user, in addition, the precious brush rod 2 is also damaged by the blade 6, resulting in loss of incalculable value.

In order to solve the aforesaid shortcomings, the present invention discloses a pen holder of a writing brush and a tool used for the pen holder. When the pen is replaced with a pen tip, the guide of the pen rod is used to track and guide the tool to avoid damaging the receiving groove. Reaming occurs on the inner periphery to effectively scrape off the glue and ensure that the new pen tip is not skewed and stably installed on the pen barrel.

In order to achieve the above object, the present invention provides a pen holder of a writing brush in one embodiment, which includes a receiving groove and a guiding portion. The accommodating groove is recessed at the head end of the pen shaft. The accommodating groove has an axial line and an inner peripheral edge that is concentric with the axial line. The inner peripheral edge of the accommodating groove can be connected to the pen head; the guide portion is provided at the head end of the pen shaft. And extending along a direction parallel to the axis line of the accommodating groove, the guide portion can guide the tool, so that the tool moves along the guide portion without the tool damaging the inner peripheral edge of the accommodating groove.

In another embodiment of the present invention, the guide portion is recessed on the axis line of the accommodating groove and has a concentric circular hole shape.

In another embodiment of the present invention, the accommodating groove has a first axis length on the axis line, the guide portion has a second axis length on the axis line, and the second axis length is greater than the first axis length.

In another embodiment of the present invention, the hole diameter of the guide portion is smaller than the hole diameter of the accommodating groove, the accommodating groove has a tapered shoulder adjacent to the guide portion, and the guide portion and the accommodating groove are drilled once. After processing, they form together at the head end of the pen.

Further, the present invention further provides a tool for a brush shaft of a writing brush, which includes a blade segment and a round rod-shaped guide protruding axially from the center of the blade segment, and the guide portion is recessed on the shaft of the accommodation groove. The center line is in the shape of a concentric circular hole. When the guide rod corresponds to the guide portion, the blade segment corresponds to the accommodation groove.

In another embodiment of the present invention, the receiving groove has a first shaft length on the axis line, the guide portion has a second shaft length on the axis line, the second shaft length is greater than the first shaft length, and the guide rod has A third axis length, the third axis length is less than or equal to the second axis length, and the third axis length is greater than the first axis length.

In another embodiment of the present invention, the outer diameter of the blade segment is substantially equal to the diameter of the receiving groove.

In this way, the guide part of the pen rod can be adapted to the guide rod of the cutter, so that when the blade section of the tool scrapes off the residual glue in the accommodating groove, the guide rod traces with the guide portion, so that the blade section can be maintained in a correct position Without deflection, the inner periphery of the accommodating groove is prevented from being damaged by the tool, thereby expanding, thinning or skewing, and affecting the service life of the pen.
