Disclosed is a ratchet tooth engagement device for a ratchet tool, comprising a ratchet wrench body (1), an assembling hole (11) penetrating through one end thereof; and a detent assembly (2), which is mounted in the assembling hole (11) of the ratchet wrench body, and comprises a ratchet base (21, 5), a ring gear disc (22, 6), an elastic element (7, 23), and a seal cover (24). A driving hole is provided in and penetrates through the ratchet base from the top to the bottom, a ring portion (212, 52) protrudes from the outer peripheral side of the ratchet base, and a tooth row (3, 9) is provided around either side or both sides of the ring portion (212, 52), the tooth row (3, 9) being engaged with row teeth (10) provided on the ring gear disc (22, 6) sheathed on the ratchet base. The seal cover (24) is sheathed on an end portion of the ratchet base (21, 5) and covers the opening of the assembling hole (11). The elastic element is sheathed to the end of the ratchet base provided with the ring gear disc (22, 6), and two ends of the elastic element (7, 23) are respectively elastically abutted against the seal cover (24) and the ring gear disc (22, 6), and are elastically pushed against the row teeth (10) of the ring gear disc to engage with the tooth row (3, 9) of the ring portion (212, 52). The device can generate a tooth skipping sound to let a user know the reversing case, and has the advantages of reduced whole weight, convenient assembly, and simple operation. |
