Description

Double-end color drawing pen

Technical Field

The utility model belongs to the painted pen field especially relates to a double-end painted pen.

Background

The color drawing pen is the instrument commonly used when children learn the painting beginners, traditional color drawing pen is exactly the crayon in fact, make rodlike refill after mixing color paste and wax, for avoiding the hand to be made dirty, the outside of refill still wraps up the one deck barrier paper except that nib one end, traditional color drawing pen has been formed promptly, but in the use, the barrier paper is damaged easily, still can make dirty hand, and, along with the use, nib one end consumes gradually and shortens to the barrier paper, still need tear the front end of barrier paper partly and just can continue to use, comparatively troublesome in the use.

In order to overcome the defects of the traditional color drawing pen, the tubular pen holder is added on the basis of the traditional color drawing pen for the existing color drawing pen, the pen core is arranged at the front part of the pen holder, the driving mechanism connected with the pen core is arranged at the rear part of the pen holder, the driving mechanism is of a screw rod type structure, and when the screw rod is rotated, the front end of the pen core can extend out of or retract into the front end of the pen holder.

The pen holder of current colour drawing pen generally is the working of plastics, difficult breakage prevents effectively that the hand from making dirty with the direct contact of refill, and simultaneously, after the end that exposes the pen holder outside of refill consumes, also need not tear the barrier paper, only need rotate the screw rod, can stretch out the pen holder with the refill again, form new, exposed end, it is also comparatively convenient to use, still have some problems, it is the required colour numerous of drawing mainly, and only a refill in the colour drawing pen, only can export a colour, this colour drawing pen quantity that requires to be equipped with when just leading to drawing is numerous, but this has brought certain degree of difficulty with regard to the management, especially to the children that the self-service ability is relatively poor, cause losing of colour drawing pen more easily. In addition, the refill only exists in the front of the pen holder, and the space behind the pen holder is occupied by the screw, so that the refill filling amount of the existing color drawing pen is small, and the service life is short.

Therefore, the existing color drawing pen has the defects of higher management difficulty and shorter service life.
