Problems solved by technology

The present invention provides a wrench, comprising an arc-shaped wrench body, the arc-shaped wrench body has a working end and a grip portion, and the working end is provided with a regular polygonal through hole, but it also has the following defects: 1. When the wrench is rotated to a certain position during disassembly, it needs to be taken out and reinstalled to continue working; 2. The wrench rotates by itself to drive the nut to rotate, which is inconvenient to use in a small space; 3. A wrench can only be installed or removed with the same specification The use of nuts is not efficient, so we have developed a grip wrench that can continuously install and disassemble the same nut without removing the wrench from the nut during the nut assembly and disassembly process, and its Nuts of different sizes can be installed or removed by installing different wrench heads

Abstract

The invention discloses a hand gripping type wrench which comprises a pawl handle, a housing handle and a ratchet wheel. The ratchet wheel is arranged in the housing handle; the pawl handle and the housing handle are oppositely arranged, and a spring is arranged between the pawl handle and the housing handle; a pawl is arranged on the pawl handle; a ratchet is arranged on the ratchet wheel; holes for mounting nuts are respectively formed in the middle part outside the ratchet wheel; when the pawl handle is held, the pawl on the pawl handle is meshed with the ratchet wheel, and at the moment, the nuts can be unscrewed or screwed down; when the pawl handle is loosened, under the action of an elastic force of the spring, the pawl on the pawl handle is separated from the ratchet wheel, and at the moment, the pawl handle can be reset and the nut is not moved. According to the invention, in the working process of assembling and disassembling one nut, the same nut can be continuously installed and disassembled without taking down the wrench from the nut.

Description

technical field [0001] The invention relates to an improvement of a wrench, in particular to a grip type wrench that can continuously install and disassemble the same nut without taking the wrench off the nut during the working process of installing and dismounting the nut, and it can By installing different wrench heads, it is possible to install or remove nuts of different sizes. Background technique [0002] In the prior art, there are many kinds of wrenches, such as Chinese patent: a wrench, application number 201220180239.8. The present invention provides a wrench, comprising an arc-shaped wrench body, the arc-shaped wrench body has a working end and a grip portion, and the working end is provided with a regular polygonal through hole, but it also has the following defects: 1. When the wrench is rotated to a certain position during disassembly, it needs to be taken out and reinstalled to continue working; 2. The wrench rotates by itself to drive the nut to rotate, whi...
