The brush hairs of a common writing brush can be classified into nine major types according to different written fonts, wherein the fonts include nine types, namely seal character, minor seal character, clerical script, regular script, running script, cursive script, wild script and the like. The total size of 18 types of brush hairs is from 4mm to 21mm according to the size of the brush hairs, the brush hairs of each size can be divided into three lengths, namely long, medium and short lengths, the middle part of the brush hairs can be divided into three hardnesses according to the elasticity, and the total number of the brush hairs of 162 types is total in terms of the size, the size and the hardness of the brush hairs. For example, when selecting a writing brush according to the requirement of the font, if the character is used as the writing body, the longer the writing brush is, the softer the writing chamber is, the smaller the elastic pressure is, and the better the writing performance is controlled. If the cursive script is used as a writing font, the shorter the length, the harder the pen belly and the larger the elastic pressure, the pen can be drawn freely, forcefully and forcefully during quick lifting, so that when selecting the brush hair, the font size is determined, the size is selected, and the hardness of the pen belly is determined according to the writing font, so that the proper writing brush is selected according to the principle.

For example, if the measured writing brush 40 is a seal writing body, the pressure values obtained by the three lengths of the long, medium and short strokes with the same stroke belly diameter of 16mm are listed as follows:

1. the detection result table of the long brush hair length:

2. the detection result table of the length of the brush hair as the middle brush hair:

3. the detection result table of the length of the short brush hairs:

from the above-mentioned detection results, the detected writing brush 40 can respectively measure different pressure values according to the length difference of the brush hairs 42, and distinguish the hardness of each brush hair 42 according to the magnitude of the pressure value measured by each length of brush hair 42, and thus distinguish the hardness of the brush hairs 42 with the same length in different materials by grading hardness, medium and soft.

It is obvious from the above description that the present invention is characterized in that the holding device 20 can be displaced relative to the base 10, as the moving member 21 of the above embodiment slides in the slide rail 14 in an oblique direction, the detected writing brush 40 fixes the pen holder 41 on the positioning seat 22, and the positioning seat 22 slides in an oblique direction along with the moving member 21 to make the brush hair 42 touch the pressure sensing member 31 to be in an elastic bending shape, the sensing device 40 can detect the pressure value of the pressed brush hair 42 and can perform soft and hard degree grading, and the soft and hard degree grading can be made on the writing brush 40 as a commodity label (not shown in the figure), so that the user can obtain the soft and hard degree grade of the brush hair 42 of the selected writing brush 40 by the commodity label without trial writing, and can thereby judge what kind of soft and hard degree the brush hair 42 of the selected writing brush 40 belongs to, so that it is no longer necessary to purchase a plurality of writing brushes for trial in a conventional way, thereby achieving the effect of convenience and applicability when the user chooses the writing brush 40.

The present invention still has different embodiments, as shown in fig. 6, a writing brush detecting machine 200 according to the second embodiment of the present invention is mainly different from the first embodiment in that the slide rail 14 of the present embodiment is horizontally disposed along the X-axis, and the pressure sensing member 31 is provided with an inclined detecting pressing plate 311 on a side different from the second pedestal 12, the detecting pressing plate 311 is flat-plate-shaped in the present embodiment and has a plane pressed by the bristles 42, and the moving member 21 of the present embodiment horizontally slides along the slide rail 14 relative to the base 10. Therefore, when the writing brush 40 is fixed on the fixing base 22 by the pen holder 41, the pen holder 41 slides horizontally along the slide rail 14 relative to the base 10 along with the moving member 21, so that the writing brush 42 is pressed against the detecting pressing plate 311, and the writing brush is pressed to an elastic bending shape along the inclination of the detecting pressing plate 311, thereby detecting the pressure value of the pressed writing brush 42 as in the first embodiment, and performing the grading of the hardness degree, so as to achieve the same effect as the first embodiment. In addition, the detecting pressing plate 311 may also be in the shape of an arc plate and have an arc surface pressed by the brush hairs 42, so as to achieve the same effect as the flat plate.

The present invention still has different embodiments, for example, the moving member drives the positioning seat to displace along a spiral track in the X-Y axial direction with the Z-axis as the central axis, for example, the moving member is a rotary cylinder (not shown) capable of lifting and rotating and is provided with the positioning seat to drive the bristles 42 to approach the detection pressing plate; alternatively, under the disclosure of the first and second embodiments, the writing brush 40 may be fixed, and the pressure sensing element is displaced to make the detecting pressing plate thereof approach to the writing brush 42 (not shown), so that the writing brush 42 can be pressed to be elastically bent to detect the pressure value of the pressed writing brush 42, and the hardness can be graded, thereby achieving the same effect as the foregoing embodiments.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments.
