ABSTRACT:
A lathe includes a stock, a shaft, a power source, gripping bars, and a platform; the stock has a shaft seat secured therein, which has a hollow holding portion, and an inner protrusion; the shaft is passed in the shaft seat in a movable manner, and has a head having a step-shaped portion and projecting into the holding space; the power source is used for actuating the shaft; the gripping bars are spaced around the shaft head, and each have inner and outer recesses; the platform has a hollow portion, and an inner protrusion right above and facing the inner protrusion of the shaft seat; when the shaft is moved upwards, the step-shaped portion will be pressed against upper edges of the inner recesses to raise the gripping bars; thus, both the protrusions are tightly held within the outer recesses of the gripping bars, and the working platform secured in position.
