The invention discloses a water-cooled glass gathering rod, comprising a gathering rod body and a gathering ball which are connected with a glass gathering machine, wherein the gathering rod body is composed of a conical rod section and a straight rod section which are connected together in a detachable manner; the straight rod section comprises a core shaft; the outer surface of the core shaft is provided with a plurality of water inlet straight grooves which are arranged at intervals; the front end and the back end of the outer surface of the core shaft are respectively provided with a front water inlet circular groove and a back water inlet circular groove which are communicated with the water inlet straight grooves; a shell in a close fit relationship with the outer surface of the core shaft is tightly sleeved on the core shaft; the shell encloses the water inlet straight grooves into a plurality of water inlet channels, encloses the front water inlet circular groove into a front water inlet circular channel and encloses the back water inlet circular groove into a back water inlet circular channel; a water outlet is disposed in the core shaft; the front water inlet channel is communicated with the water outlet; and the shell is provided with a water inlet communicated with the back water inlet circular channel. The gathering rod has a good cooling effect and cannot generate thermal deformation easily.
