ABSTRACT:
A body-building machine includes a locating frame having an head portion integrally formed at a top thereof. The head portion defines an open chamber and a pair of opposed holes at two side walls thereof. A locating plate having an inclined end portion is inserted into the open chamber and is received in the locating frame. A pair of tubular lugs are formed at an intersection between the locating plate and the inclined end portion, aligning with the pair of opposed holes. A cladding plate having a plank with an angled portion is received in the open chamber. A tube is formed at an intersection between the plank and the angled end portion, aligning with the tubular lugs. A shaft extends through the opposed holes, the pair of tubular lugs and the tube to engage the locating plate with the plank and to form a short tension arm above shaft and a long tension arm below the shaft. An elastic return mechanism is disposed between the inclined end portion and the angled end portion in the short tension arm portion.
