The invention discloses a gel pen in a dolphin heading ball rotation shape. The gel pen in the dolphin heading ball rotation shape comprises a pen case, a pen cap, a rotation ball, a pen head and a pen core, wherein an external thread is arranged on the side wall of the lower end of the pen head, an internal thread cooperatively used with the external thread is arranged on the inner wall of the upper end of the pen case, the pen case and the pen head are connected through the internal thread and the external thread, the pen head is installed in the pen case, and the pen cap which sleeves the pen head is arranged above the pen case. The gel pen in the dolphin heading ball rotation shape is overall designed in the slender dolphin shape, and a rotation ball which can rotate by 360 degrees isarranged at the top of the dolphin shape, and then the gel pen in the dolphin heading ball rotation shape not only is unique in appearance and catches people's eyes, but also improves interestingnessof the gel pen by arranging the rotation ball at the top, and furthermore a separation plate, a large metal ball and a small metal ball are arranged in the rotation ball, and then when the rotation ball rotates, the inner large metal ball and the inner small metal ball perform centrifugal rotation along with the rotation ball, and certain sounds are continuously sent out along with the centrifugalrotation, and therefore the gel pen in the dolphin heading ball rotation shape can attract attention well, and achieves the effect of relieving pressure.
