Explosion-proof complete set of boxed sleeves 2035, 2036

The complete set of boxed socket wrenches has an expanded application range, has a simple overall structure and is 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. ▲▲The socket wrench includes a body with a clamping portion at one end, an outer sleeve and a plurality of socket assemblies that are movably installed in the front-rear direction. In order to adjust the movement of the outer sleeve and the plurality of socket assemblies in the front-rear direction, the socket wrench includes The adjustment member is characterized in that it has an opening on the body for fitting the outer sleeve, an opening groove provided with a ratchet mechanism and communicating with the opening, and an extended step portion integrally formed on the opening groove in front of the opening groove. The locking hole and the ratchet setting groove are respectively formed, and 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 a concave and convex portion sleeve integrally formed along its inner side. The fitting recess of the barrel assembly and the sawtooth portion integrally formed along the outer upper part of the barrel assembly are combined by the front and rear adjustment members, which are composed of an action lever and an adjustment knob connected to the action lever. The action lever is integrally formed, and its cross section is elliptical and extends in the inward and outward directions. The protruding end of the socket wrench 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 shaft.
▲▲Heavy-duty socket wrenches are widely used in petrochemical, mining, coal mining, gas production, power generation, metallurgy, aviation storage and transportation, pharmaceutical gas production, plastics, leather, fireworks and firecrackers and other industries. Heavy duty socket wrenches are made of beryllium copper alloy and aluminum copper alloy. Socket tools have the advantages of precise dimensions, tensile strength, and good wear resistance than ordinary steel tools. The surface treatment of the product is black coating and gray hammer pattern spraying.
Heavy-duty sockets are available in metric and imperial systems. Although the concave shape of the socket is the same, the socket head is a concave hexagonal cylindrical sleeve. The inner hexagonal ribs of the cylindrical socket are arranged in sequence according to the bolt model and can be selected as needed.
Socket head refers to the abbreviation of socket wrench. Simply put, it is a special tool for tightening or loosening screws. It is specially used to tighten the threaded fasteners of hexagonal nuts.
Special hand tools need to be produced according to drawings or construction intentions. It is different from civilian hardware tools. Higher hardness, larger and thicker body, wider application range. Steel adjustable wrench, steel percussion torx wrench, steel percussion dead wrench, special socket, steel wrench, steel hexagonal crowbar. Top thimbles, listening needles and more!
