A palm ratchet tool comprises an upper cover (1), a lower cover (4), a ratchet (3), a pawl rocker shifter (5), and bits (2). The upper cover is provided with multiple through holes (11). The multiple bits are respectively disposed in the through holes. The pawl rocker shifter is disposed between the upper cover and the lower cover. The pawl rocker shifter comprises a left pawl (51), a right pawl (52), and a rocker (53) connected to the left pawl and the right pawl. The lower cover is connected to the bottoms of the bits.
