Bulb with fuse-positioning structure

The utility model relates to a bulb with a fuse-positioning structure, comprising a bulb housing and a stem. Two parallel conducting wires above a circular bead fixedly connected with the stem are respectively provided with a groove with a concave bending angle to cause grooves with concave bending angles arranged on the two conducting wires to form an opposite state in a close range; a fuse is wound and inserted into the two grooves with bending angles to cause horizontal pitch between the wound fuse to be smaller than the spacing of the two parallel conducting wires; the fuse is wound and inserted into the two opposite grooves with the bending angles to make the fuse not loose to slip in order to guarantee the fuse to be inserted and positioned and not to slip.
