Both ends of the push rod penetrate the pen shell 2 and form an elastic fit with the outer wall of the pen shell 2 through a spring three 20. In the initial position, the push rod is in a balanced state through two springs three 20, and at this time, the center position of the push rod is aligned with the liquid outlet 6. A trapezoidal protrusion 7 is provided at the center position of the push rod, and the trapezoidal protrusion 7 is sealed with the liquid outlet 6 in a balanced state. A ball pen tip 14 and a brush pen tip 15 are respectively provided on the push rod located on both sides of the trapezoidal protrusion 7. The ball pen tip 14 and the brush pen tip 15 both form an elastic fit with the push rod, and the ball pen tip 14 and the brush pen tip 15 form a linkage fit with the push rod.

A double-tip moss brush is provided in Example 1. The brush can perform diversified creations by switching different nibs. As shown in Figure 2, to switch to a ball brush that is convenient for filling patterns, the left push rod needs to be pushed to the bottom first. At this time, the brush tip 15 moves to the right, and the spring 13 is gradually compressed. The lower end of the brush tip 15 is against the platform on the right side of the pen shell 2. At the same time, the ball tip 14 also moves to the right, and gradually falls during the movement. The ball tip 14 extends out of the pen mouth, and the triangular protrusion on the ball tip 14 falls on the push rod at the lower end, and the upper end is stuck with the liquid outlet 6, so that a ball brush shape of a double-tip moss brush can be obtained, and uniform ink discharge can be achieved.

As a preferred embodiment 2, the trapezoidal protrusion 7 divides the push rod into a left push rod 10 and a right push rod 11, the ball pen head 14 is installed on the left push rod 10, and the brush pen head 15 is installed on the right push rod 11, and the installation position of the ball pen head 14 and the installation position of the brush pen head 15 are symmetrical about the trapezoidal protrusion 7. It is convenient to push the rod and ensure that the installation position can be aligned with the liquid outlet 6 after pushing the rod.

At this time, the exposed length of the left push rod 10 is less than the exposed length of the right push rod 11, the trapezoidal protrusion 7 moves rightward to release the blockage, and the roller ball pen tip 14 moves synchronously with the left push rod 10. At this time, the spring one 12 gradually releases energy until the bottom of the roller ball pen tip 14 is exposed from the pen mouth 16. The top of the roller ball pen tip 14 forms a limited fit with the left push rod 10 because of the triangular protrusion one 8. The roller ball pen tip 14 is in a balanced state at this time, and the top is connected to the liquid outlet 6 to form an ink supply fit, and the spring two 13 is further compressed;

Brush tip state: push the right push rod 11 inward to the bottom, the spring three 20 at the right push rod 11 is compressed, and the spring three 20 at the left push rod 10 is stretched. At this time, the exposed length of the left push rod 10 is greater than the exposed length of the right push rod 11, and the trapezoidal protrusion 7 moves left to release the blockage, and the brush tip 15 moves synchronously with the right push rod 11. At this time, the spring two 13 gradually releases energy until the bottom of the brush tip 15 is exposed from the pen mouth 16. The top of the brush tip 15 forms a limited fit with the right push rod 11 because of the triangular protrusion two 9. The brush tip 15 is in a balanced state at this time, and the top is connected to the liquid outlet 6 to form an ink supply fit, and the spring one 12 is further compressed;

Reset state: When the force of the left and right push rods disappears, the push rods quickly reset under the energy release action of the springs 20 on both sides until they return to their initial state.
