Zusammenfassung:	The utility model provides a bicycle head structure which comprises a vertical pipe, a lower pipe, an upper pipe, a lifting mechanism, an anti-rotation limiting mechanism and a front fork. The lower pipe comprises an inner peripheral wall; the lower end of the upper pipe is movably inserted into the first end of the lower pipe, the upper end of the upper pipe is connected to the vertical pipe, the upper pipe comprises a peripheral wall, and the interior of the upper pipe and the interior of the lower pipe form a containing space. The lifting mechanism is located in the containing space and acts to allow the upper pipe to move relative to the lower pipe. The anti-rotation limiting mechanism is located between the inner peripheral wall and the outer peripheral wall, and the front fork is connected to the second end of the lower pipe. Therefore, through the structural configuration that the lifting mechanism is arranged in the containing space, the upper pipe can move relative to the lower pipe, the height of th
