ABSTRACT:
A torch includes a head member, a tail member, and a bellowed intermediate flexible hose member connected threadedly to the head and tail members. The head member includes a bulb unit disposed therein, and an on-off switch which is mounted on the head member and which is capable of energizing the bulb unit upon actuation. The tail member includes a cell unit for supplying power to the bulb unit. One of the head member and the tail member has an internally threaded end section, while the other of the head member and the tail member has an externally threaded end section. The hose member has an externally threaded end section, an internally threaded end section, and two conductive contact sets respectively located in the end sections of the hose member in such a manner that one of the conductive contact sets is in electrical contact with the bulb unit while the other one of the conductive contact sets is in electrical contact with terminals of the cell unit. The tail and head members can be detached easily from the hose member so as to interconnect the head and tail members, thus forming an ordinary torch, wherein the bulb unit of the head member and the terminals of the cell unit in the tail member are coupled together electrically.
