发明名称 STRUCTURE OF A RATCHET WRENCH
摘要 The structure of a ratchet wrench has a ratchet and a brake wheel that engage with each other, and a redirecting mechanism which switchs the rotating direction of the ratchet. The redirecting mechanism has a transmission axle pivotally installed inside the brake wheel. The transmission axle has a pushing assembly for pushing the brake wheel to deviate. The pushing assembly changes its pushing direction as the transmission axle rotates, thereby changing the rotatable direction of the ratchet.

主权项 1. A ratchet wrench structure comprising: a body having a first tank and a second tank, the first tank being provided with a ratchet surrounded by a ratchet part and the two opposite sides inside the second tank having respectively an engaging tooth section; a brake wheel disposed inside the second tank and having an accommodating space, the brake wheel being surrounded by a brake tooth part to engage with the tooth part of the ratchet, and a stopping tooth part to engage with one of the engaging tooth sections of the second tank; and a redirecting mechanism disposed in the second tank and having a transmission axle pivotally provided in the accommodating space of the brake wheel; the transmission axle having a pushing assembly to pushing the inner side of the accommodating space, thereby pushing the brake wheel to deviate; the pushing assembly being free to change the pushing direction thereof as the transmission axle rotates, so that the stopping tooth part of the brake wheel selectively engages with one of the engaging tooth sections of the second tank, thereby changing the rotatable direction of the ratchet.
