Gel ink pen capable of being bent into ring shape

The invention discloses a gel ink pen capable of being bent into a ring shape. The gel ink pen comprises a pen point, a bend guiding pen body, a pen tail and a water storage bin. The bend guiding penbody comprises a plurality of sections of bend guiding pipes which are sequentially hinged together. The pen point is hinged to the bend guiding pipe at the foremost end, and the pen tail is hinged tothe bend guiding pipe at the rearmost end. Included angle notches are formed in the same sides between every two adjacent bend guiding pipes, between the pen point and the bend guiding pipe connectedwith the pen point and between the pen tail and the bend guiding pipe connected with the pen tail. The pen point, the bend guiding pen body and the pen tail can be bent towards one sides of the included angle notches to form the ring shape, and therefore the gel ink pen can be worn on a wrist. When the gel ink pen is used, a limiting locking mechanism is arranged on the bendable side of the gel ink pen so as to ensure that
