The ratchet mechanism includes a ratchet ring rotatably disposed within the ratchet groove relative to the body about the rotational axis. The ratchet ring is axially provided with a first end and a second end opposite the first end along the rotational axis, and the ratchet ring is provided with a driving hole connecting the first end and the second end. A distance from the first end to the second end forms a thickness, and a width of the driving hole capable of engaging with a threaded member forms an engagement width. The ratio of the thickness to the engagement width is less than
