Description

Technical Field

[0001] The utility model relates to the technical field of acrylic pens, in particular to a double-headed acrylic pen. Background Art

[0002] Acrylic brushes refer to brushes made of nylon or acrylic fiber in various shapes that are specially used for painting with acrylic or polymer paints. Because these paints dry very quickly, the brush dipped in paint should be placed in water for use. Acrylic and nylon brushes are not like other pens with hair or natural bristles. They will not be affected by prolonged soaking time. Nowadays, the nib and pen holder of acrylic pens are mostly integrated. When the bristles of the nib are damaged, the bristle nib cannot be replaced separately, and the entire acrylic pen cannot be used again, resulting in a waste of resources.

[0003] After searching, a Chinese patent discloses an acrylic pen (authorization announcement number CN219360700U), including a pen holder, a sleeve is sleeved on the top of the pen holder, the outer surface of the sleeve is bent outward and fixedly connected with a pressure rod, the outer surface of the sleeve is provided with a strip groove, the pressure rod corresponds to the strip groove, the inner side of the pressure rod is fixedly connected with a clamping block, the outer surface of the pen holder is provided with a clamping groove, the clamping block is clamped in the inside of the clamping groove, the length of the strip groove is equal to the length of the pressure rod, the width of the strip groove is equal to the width of the pressure rod, and the top of the sleeve is fixedly connected with a fixed sleeve. Although the patented technology sleeves the sleeve on the top of the pen holder, presses the pressure rod inward, the pressure rod is bent inward and clamped into the strip groove, the clamping block will be inserted into the clamping groove on the pen holder, which is convenient for disassembly and assembly of the sleeve. When the bristles of the pen tip are damaged, the pen tip can be replaced, which saves resources, and different types of pen tips can be replaced as needed, which improves the use effect.

[0004] However, the above device still has some disadvantages in actual use. The most obvious one is that the pen holder in the above acrylic pen is set as an integral whole, and the length of the pen holder cannot be adjusted according to the size of the user's palm. The pen holder of the above acrylic pen is relatively long. When used by primary school students or girls with smaller palms, the user's experience may be reduced due to the long pen holder, thereby failing to achieve the best use effect.
