Multi-function torch

A torch comprising:

• a barrel adapted to receive a battery unit therein and having a front end portion and a rear end portion opposite to said front end portion in an axial direction;
• a lamp seat unit including
• a tubular seat member mounted on said front end portion of said barrel and having a front section formed with a key projection, and a rear section opposite to said front section in the axial direction,
• a lamp positioning plate disposed in said front section of said seat member, and
• a lamp held by said lamp positioning plate;
• a tubular coupling member made of a light transmittable material and having a front end, a rear end and an annular inner wall surface between said front and rear ends, said inner wall surface being formed with a spline groove, said coupling member being sleeved around said seat member such that said key projection extends into and is slidable along said spline groove, said rear end of said coupling member being formed with a radial inward end flange that contacts tightly and slidingly said seat member, said coupling member being axially shiftable relative to said seat member between a first position, where said end flange contacts said rear section of said seat member, and a second position, where said end flange abuts against said key projection to prevent removal of said coupling member from said seat member;
• and
• a head cap secured to said front end of said coupling member and provided with a reflector therein;
• said lamp extending into said reflector so that light may be directed axially when said coupling member is disposed at the first position;
• said lamp being located in said coupling member and at least partially withdrawn from said reflector so that light can pass radially through said coupling member when said coupling member is disposed at the second position.
