Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

When the novel pen point structure is implemented, the novel pen point structure comprises a pen point base 2, a contraction sleeve piece 5 and a pen core fixing seat 8, wherein five combined petals 1 with the same specification are equidistantly arranged at one end of the pen point base 2, and a groove 3 is formed in the other end of the pen point base;

the upper part of the tightening sleeve 5 is provided with a pen core passing cavity 4, and the lower part of the tightening sleeve is provided with a connecting cavity 6;

a fixing cavity matched with the refill 7 is formed in the refill fixing seat 8, a connecting part 10 is arranged at the lower part of the refill fixing seat 8, and the specification of the connecting part 10 is matched with that of the groove 3;

the main body of the combined valve 1 at one end of the pen point is of a one-fifth hemispherical structure, and the five combined valves 1 are contracted and combined towards the direction of the sphere center to form a hemispherical structure with the diameter of 0.5 mm;

the refill 7 is internally provided with a coiled core which can be used for storing and conveying ink.

And a cavity opening at the lower part of the connecting cavity 6 of the tightening sleeve piece 5 is sleeved from one end of the pen point of the combined valve 1 until the pen point base 2 and the tightening sleeve piece 5 are fixed, and five combined valves 1 form a hemispherical structure.

The refill fixing seat 8 is placed in from the lower cavity opening of the connecting cavity 6 until the convex part 9 is buckled with the groove 3 to finish fixing.
