The invention relates to the field of wiring tools, and particularly relates to a wiring gun capable of being applied to fiber-to-the-home. The wiring gun comprises a glue smelting gun and a gun head, wherein the gun head is fixed at a glue outlet of the glue smelting gun. The wiring gun is characterized in that the gun head comprises a melt glue extruding head and a wire pressing piece which is rotatably assembled on the melt glue extruding head, the melt glue extruding head comprises a glue inlet connected with the outlet of the glue smelting gun and a glue outlet communicated with the glue inlet, the wire pressing piece is provided with a wire leading groove communicated with the glue outlet correspondingly, the melt glue extruding head is provided with an opening which is provided for a cable to pass through along the radial direction so as to get into the wire leading groove, the wire leading groove can be communicated with the opening and the glue outlet in a directly facing manner respectively along with rotation of the wire pressing piece, and a part, which is located at the groove bottom of a wire outlet end of the wire leading groove, of the wire pressing piece is provided with a wire pressing head used for press-fitting the cable. The wiring gun provided by the invention can greatly expand the application range, not only can carry out wiring on various optical fibers, but also can carry out wiring on electric wires in required conditions, and solves problems of poor universality and narrow application range of the wiring gun.
