The invention discloses a domestic well water fetching device. The domestic well water fetching device comprises a hollow shell, a connecting shell and a mounting plate, wherein the connecting shell is fixed to the bottom of the hollow shell, and the mounting plate is fixed to the bottom of the connecting shell. The center of the hollow shell is of a hollow structure and forms a liquid draining space, and a center shaft is arranged in the center, located in the liquid draining space, of the hollow shell. One end of the center shaft is inserted in the inner wall of the hollow shell, and the other end of the hollow shaft penetrates through the hollow shell. A circular plate is fixed to the end, located outside the hollow shell, of the center shaft, the end of the center shaft is fixed to the center of one end face of the circular plate, and a hand wheel rod is fixed to the other end face of the circular plate. According to the domestic well water fetching device, through the one-way valve principle and the curved bar principle, water pumping work is achieved, the domestic well water fetching device can be full of water when used for water pumping, and thus the speed and efficiency of water pumping are increased; and in addition, through the symmetrically-arranged water pumping principle, a user does not do useless work for the domestic well water fetching device every time.
