Abstract

The invention relates to a ratchet wrench comprising a body, a drive head, a ratchet wheel, at least one ratchet block and a reversing device. The body is provided with a chamber including a first section and a second section. The drive head is rotatably provided at the first section; two opposite ends of the drive head are provided with a first toothed portion and a dive portion; the first toothed portion surrounds the outer periphery of the drive head; the drive portion can drive a member to be driven. The ratchet wheel is rotatably disposed at the second section of the chamber and comprises a second toothed portion and a third toothed portion; the second toothed portion and the second toothed portion surround the two opposite ends of the outer periphery of the ratchet wheel, respectively; the second toothed portion meshes with the first toothed portion of the drive head; the toothed blocks are slidably disposed at the second section of the chamber; each ratchet block comprises a fourth toothed portion which is arranged on one end face, close to the ratchet wheel, of the ratchet block; each fourth toothed portion selectively meshes with the third toothed portion of the ratchet wheel; the reversing device is pivoted to the body and abutted to the ratchet blocks.

Description

technical field [0001] The invention mainly discloses a ratchet wrench, especially a reversing ratchet wrench. Background technique [0002] The structure of the traditional ratchet wrench is mainly provided with an accommodating hole in the ratchet wrench, and a ratchet can be accommodated in it. The outer periphery of the ratchet has occlusal teeth, and the accommodating hole is provided with an accommodating groove on one side, and the accommodating groove is in an appropriate position. A pivot rod is protruded, and a gear can be pivoted on the pivot rod. The teeth of the gear mesh with the occlusal teeth of the ratchet. The tooth part, after being inserted into the rod body, can mesh with the teeth of the gear. The digital control component can be placed in the accommodation groove to control the forward and reverse rotation or unidirectional rotation of the ratchet. Therefore, the space of the accommodation groove can be set The control component controls the forward a...
