Embodiment 1

[0019] Such as Figure 1 to Figure 3 As shown, the multi-core pen includes a pen case 2 and two refills 1, the pen refill 1 is composed of a pen holder 11 and a nib 12, the inner cavity of the pen case 2 is a refill chamber 21, and the refill 1 is loaded into the refill chamber 21, and the The pen cover is filled with a filler 22 made of wooden material to fix the refill 1, and the nib 12 is exposed at one end of the pen cover 2 at the same time, and the nibs 12 are on the same plane, and the nibs are equally spaced on the same circumference, and the nibs are spaced between each nib. The distance is 3mm. Certainly, filler 22 also can be made by as the plastic material of resin; During use, be positioned at the nib of circumference bottom and paper surface contact, pen cap and paper surface are 40~60 degrees, this distance and angle can guarantee that writing will not There are multiple refills in contact with the paper surface at the same time, which improves the writing qual...

Embodiment 2

[0022] Such as Figure 4 and Figure 5 As shown, two fixing frames 3 are arranged at intervals in the refill cavity 21 of the pen cover 2, and four fixing holes 31 are arranged on the fixing frame 3 to fix four refills 1 respectively. 3 is fixed in the pen case 2 in the fixing hole 31. The four nibs 12 are exposed at one end of the pen cover 2 at the same time, and all the nibs 12 are on the same plane, and the nibs are equidistantly distributed on the same circumference, and the distance between the nibs is 2 mm.

[0023] The fluorescent multi-core pen has a simple structure and is convenient to process; it can be used in places with dark light to prevent damage to eyesight.

Embodiment 3

[0025] Such as Figure 6 and Figure 7 As shown, the refill cavity 21 of the pen cover 2 is provided with a fixed plate 4, and two countersunk holes 41 are respectively provided on both sides of the fixed plate 4, and the four refills 1 are inserted through the pen holder 12 and stuck in the fixed holes of the fixed frame 3 In 31, the afterbody of 4 penholders is respectively inserted in the counterbore 41 on fixed disk 4 both sides, realizes spacing. Four nibs 12 are exposed at both ends of the pen case 2 at the same time, and all the nibs 12 on the same side of the pen case 2 are on the same plane, and the nibs are equidistantly distributed on the same circumference, and the distance between the nibs is 3mm.

[0026] The fluorescent multi-core pen has a simple structure and is convenient to process; it can be used in places with dark light to prevent damage to eyesight.

Abstract

The invention relates to a fluorescent multi-core pen, which includes a pen case with a refill cavity and a pen core. The pen core is composed of a pen holder and a pen point. At least two pen cores are fixed in the pen case. There are two nibs at one end outside the pen case; a layer of fluorescent powder is arranged on the outer surface of the pen case; the fluorescent multi-core pen has a simple structure and is convenient to process; it can be used in dark places to prevent damage to eyesight.

Description

technical field [0001] The invention relates to a writing instrument, in particular to a fluorescent multi-core pen. Background technique [0002] In the traditional multi-core pen, multiple refills of different colors are fixed in a large pen case, and only the nib of one refill is exposed from the pen case, and the switching between multiple refills is realized through the sliding of the mechanical mechanism . Traditional multi-core pens do not have lighting facilities, so they cannot be used when the light is low. Contents of the invention [0003] The object of the present invention is to provide a fluorescent multi-core pen, which can effectively solve the problems in the background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a fluorescent multi-core pen, including a pen case and a pen core with a pen core chamber, the pen core is composed of a pen holder and a pen tip, at least two pen...
