The applicable range of the socket wrench is expanded, the overall structure is simple and easy to manufacture. The front and rear adjustment components of the ratchet mechanism are configured with a three-stage stop compression spring and a tension spring on the ratchet wheel. In addition to the rear sleeve component, a front sleeve component is also provided to engage each outer sleeve and sleeve assembly. Since there is no mutual interference between components in the sleeve assembly, tool wear can be suppressed and durability life can be improved while making operation simple. Explosion-proof socket wrench type socket wrench is widely used in petrochemical industry, mining, coal mining, gas production, power generation, metallurgy, aviation storage and transportation, pharmaceutical gas production, plastic leather, fireworks and firecrackers and other industries.
The explosion-proof socket wrench includes an outer sleeve and a plurality of socket assemblies that are movably mounted in the front-rear direction on a body having a clamping portion at one end thereof. In order to operate the outer sleeve and the plurality of sleeve assemblies in the front-rear direction. The front and rear adjustment member for adjustment is characterized in that the main body has an opening for fitting the outer sleeve, an opening groove provided with a ratchet mechanism and communicating with the opening, and an integrally formed protruding step portion located in front of the opening groove. A locking hole and a ratchet setting groove are respectively formed on the open groove. A flange portion with a concave portion inclined along its inner side and a plurality of concave and convex portions extending along its inner and outer directions are formed on the sleeve. The outer sleeve has an integrally formed groove along its inner side. The fitting recess of the concave and convex part of the sleeve assembly and the sawtooth part integrally formed along the outer upper part of the front and rear adjustment member are composed of an action lever and an adjustment knob connected to the action lever. The action lever is integrally formed with an elliptical cross-section along the edge. The protruding end socket wrench protruding in the inward and outward directions has a cylindrical portion with a plurality of elastic restraint grooves and an protruding portion formed on the adjustment knob while being integrated with the rear central axis.
