  • Patent number: 6695643
    Abstract: A lamp shaft of a Do-It-Yourself (DIY) lamp fixing in a wire connection casing composes a fixing base and an inserting shaft. The fixing base is coupled and secured to a through hole on the lateral side of a wire connection casing. An inserting shaft is inserted into the through hole of the fixing base. By rotating the inserting shaft, the embedding member and the slanted elastic plate are driven to press tighter and tighter with each other and forces the embedding base to be securely fixed onto the fixing base. Such arrangement can reduce the transportation and storage amount of material since the wire connection casing and the inserting shaft can be detached and disposed separately. Furthermore, when the user carries the lamp, he/she does not need other tools for assembly, and it attains the function of facilitating the user's DIY assembly.
