DUAL PAWL RATCHET MECHANISM AND REVERSING METHOD |
摘要 |
<p>A dual-pawl ratchet wrench mechanism is disclosed having a stop mechanism for limiting over-travel of a reversing lever for selecting drive directions. The stop mechanism is formed on a disc is selectively engageable with first and second pawls to move the pawls into and out of engagement with a ratchet gear to determine a torque drive direction, the ratchet gear capable of providing torque to a working piece in the selected drive direction. The design simplifies manufacturing. Additionally, the reversing lever is assembled with the mechanism in a manner to improve sealing.</p> |
