ABSTRACT:
A telescopic shaft magnetic retriever includes a telescopic shaft having a conductive battery holder at a tip thereof, and an insulative and transparent lamp holder adapted to hold a lamp and a magnet for retrieving screws, nuts, tools and other steel parts from inaccessible places. The lamp has a first contact connected electrically to a pole of the battery set and a second contact. The lamp holder allows passage of light emitted from the lamp. The retriever further includes a conductive tubular sleeve which is connected threadedly to the conductive battery holder and the lamp holder and which has an end surface in electrical contact with the second contact of the lamp. The battery set, the conductive battery holder, the conductive tubular sleeve, and the lamp constitute an electric circuit. The lamp is switchable by rotating the tubular sleeve relative to the lamp holder.
