A moving frame structure of a hand puller is used for driving a ratchet to rotate with a turning of two side panels when a pressing portion is placed into a ratchet gear. When the pressing portion at the two side panels is separated from the ratchet gear, the two side panels are swung with respect to the axis of the rotating shaft. When the two side panels are moved to a circular arc surface and separated from the circumferential surface of the rotating shaft and a notch is aligned precisely with the rotating shaft, the pressing portion is placed into the ratchet gear to achieve a blocking effect. By pulling the fastening member backward, the pressing portions on both sides are retracted and separated from the ratchet gear of the ratchet completely, so that the rotating shaft can be withdrawn from the socketing hole through the notch.
