Abstract

The invention relates to a ratchet wrench, which includes a head, and a ratchet, a positive braking group, a reverse braking group, and a reversing member are built in the head. By switching the reversing member, the forward braking group, the reverse The braking group abuts against the ratchet, and when the ratchet is rotated, each of the detents contained in the braking group abutting against the ratchet engages the ratchet alternately, so as to reduce the necessary swing angle of the ratchet wrench.

Description

Technical field

[0001] The present invention is a ratchet wrench for reciprocating pulling locking screws. Background

[0002] Ratchet wrench is roughly divided into ratchet has a form of a hole, for example, Taiwan Patent I647072, or ratchet has a sleeve connection part in the form of a connecting sleeve, for example, Taiwan patent M576088. The greater the number of teeth of the ratchet, the smaller the necessary swing angle of the wrench, which is conducive to the construction of a narrow area. But the number of ratchet teeth can be set limited by the size of the ratchet, the number of common teeth is mostly 72 teeth, the necessary swing angle of the wrench is 5 degrees, with the development of science and technology, the items are getting smaller and smaller, the various appliances are more and more crowded, for the necessary swing angle is smaller Ratchet wrench can be said to be more and more demanded, if you want to reduce the swing angle must continue to increase the numbe...
