The width of the opening is gradually reduced toward the direction of the receiving space, the first guide surface guides the holding part into the receiving space, and the hook and the holding part are mutually held and fixed. By arranging the first guide surface, it is easier for the holding portion to enter the accommodating space.

Further, the pen tip includes a front part and a rear part, the holding part is located in the front part, the rear part is connected with the pen holder, the width of the rear part is larger than the width of the front part, and the width of the rear part is larger than the minimum width of the opening to prevent the rear part from entering into the pen. inside the opening.

Further, the holding part includes a protruding block arranged on the outer side of the pen tip, the protruding block is inclined to form a second guide surface toward the direction of the pen holder, the thickness of the protruding block is gradually thickened toward the direction of the pen holder, and the protruding block and the hook are formed. They can be held with each other, and the protrusions and the hooks can be held with each other, so that the holding part and the fixing part are firmly connected and not easily separated.

Further, the protruding block enters the accommodating space along the first guiding surface on the hook through the second guiding surface.

Further, the holding portion has elasticity, and the width of the pen tip and the holding portion is greater than the minimum width of the opening, and the elasticity of the holding portion enables the pen tip and the holding portion to enter the accommodation space through the opening, while the width of the holding portion and the pen tip It is larger than the minimum width of the opening, so that the holding part is held in the opening.

Further, the pen holder is made of elastic rubber, so that the pen holder has better bending performance.

The working principle of the above-mentioned spiral refills for various uses: when the ink in the pen holder is used up, the head and tail ends of the pen holder are connected to each other through the clamping part and the fixing part to form a ring.

Compared with the prior art, the utility model has the following beneficial effects:

In the multi-purpose spiral pen refill of the present invention, after the ink in the pen holder is used up, the head and tail ends of the pen holder are connected to each other through the mutual clamping of the nib holding part and the fixing part to form a ring, which can be used for other purposes , the structure is simple, the connection is convenient, and the material waste caused by directly discarding the refill is avoided.

The multi-usage spiral pen core of the utility model has a spiral pen holder, which can accommodate more ink and has a longer service life.
