Abstract
A light-guiding tool shank, a handle unit, a light-emitting element and a power allocation unit are assembled together to form a light-emitting fastening tool. The light-guiding tool shank includes a shank body, a light-guiding portion and a fastener fixing head. The shank body has a first and a second end; the light-guiding portion is formed in the shank body to locate between the first and the second end of the shank body; and the fastener fixing head is located at the first end of the shank body and defines a light projecting hole that is communicable with the light-guiding portion. With these arrangements, the light-emitting fastening tool enables a user to quickly sort out a desired fastener and align the same with a predetermined fastener fixing position even in a dark working environment or in the night, so that the fastener can be fixed in increased working efficiency.
