Multipurpose ratchet wrench

Abstract

The invention discloses a multipurpose ratchet wrench. The multipurpose ratchet wrench comprises two ratchet wheels, a connection mechanism used for being fixedly connected with the two ratchet wheels, and a reversing mechanism used for adjusting rotating directions of the ratchet wheels, wherein the connection mechanism comprises two pressing boards, arranged in a bilateral symmetric mode, and a clamping board fixed between the two pressing boards, the two ratchet wheels are fixed to the front and rear ends of the clamping board through the pressing boards respectively, the reversing mechanism comprises two sets of reversing assemblies which match the two ratchet wheels respectively, the reversing assemblies comprise poking pieces locally meshed with the outer edges of the ratchet wheels, steel balls used for jacking the poking pieces, and adjusting springs which match the steel balls, the poking pieces are arranged between the ratchet wheels and the clamping board in a pokable and clamped mode, and the steel balls and the adjusting springs are all fixed to positions, close to the poking pieces, of the interior of the clamping board. The multipurpose ratchet wrench is simple in structure, low in cost and convenient to operate, and not only can the ratchet wrench be prevented from over travel, but also the ratchet wrench can be prevented from unwanted reversal switches.

Description

technical field [0001] The invention relates to the technical field of oilfield drilling auxiliary tools, in particular to a multi-purpose ratchet wrench. Background technique [0002] In the process of drilling in oil fields, ratchet wrenches are generally used to fasten or loosen screws or nuts. However, the existing ratchet wrench is prone to problems of overtravel or unintentional reverse switching during operation, which greatly affects the working effect of the ratchet wrench and reduces work efficiency. At the same time, the existing ratchet wrench often only has one ratchet, which cannot be applied to screws or nuts of different specifications, and needs to be constantly replaced. In addition, most of the existing ratchet wrenches have relatively complicated structures, which will increase the burden on production cost and assembly, and the production cost is high. Contents of the invention [0003] In order to solve the problems of the technologies described abo...

AI Technical Summary

Problems solved by technology

However, during the operation of the existing ratchet wrench, the problem of overtravel or unintentional reverse switching is often prone to occur, which greatly affects the working effect of the ratchet wrench and reduces the work efficiency.

At the same time, the existing ratchet wrench often only has one ratchet, which cannot be applied to screws or nuts of different specifications, and needs to be replaced continuously

In addition, most of the existing ratchet wrenches have relatively complicated structures, which will increase the burden on production cost and assembly, and the production cost is high.
