The invention relates to a handle positioning device. The handle positioning device comprises a pin base, and is characterized in that a cavity is formed in the pin base; a first through hole is formed in the pin base on the left side of the cavity; a second through hole is formed in the pin base on the right side of the cavity; pin shaft modules are arranged in the first through hole and the second through hole, and include pin shafts and handles arranged at at ends of the pin shafts; the two ends of the pin shafts are respectively arranged in the first through hole and the second through hole; the pin shafts are coated with stop sleeves; pin holes are radially formed in the pin shafts; pins are arranged in the pin holes; two ends of the pins extend out of the outer peripheral surfaces of the pin shafts, and are clamped in inner holes of the stop sleeves; the pin shafts penetrate through the cavity; the pin shafts in the cavity are coated with springs; one ends of the springs are ejected against one side of the cavity; and the other ends of the springs are ejected against the stop sleeves. One ends, penetrating through the first through hole, of the pin shafts are connected with rotating pieces. An arc guide surface is arranged at the right end of the pin base. The handle positioning device is not influenced by a gravity factor, and is used for displacement limit of non-fixed pieces.
