Explosion-proof combination socket wrench Explosion-proof socket wrench combination tool

There are two main materials for explosion-proof tools

Aluminum bronze and beryllium bronze. Smelted from nickel-aluminum-nickel-beryllium alloy
Beryllium bronze tools are national
Ⅱ
products. They will not explode when working in hydrogen with a concentration of
. Aluminum bronze tools are national
br/> Grade II
products will not explode when operating in hydrogen gas with
concentration. Because beryllium bronze material has zero magnetism, beryllium bronze tools are also called anti-magnetic tools and can operate safely in magnetic field environments.
The combined socket wrench has an expanded application range, a simple overall structure and is easy to manufacture. The front and rear adjustment components, the ratchet mechanism, are equipped with a three-level stop compression spring and a tension spring on the ratchet wheel of the ratchet mechanism. In addition, in addition to the rear sleeve component, a front sleeve component is also provided, on which each outer side is joined. Since the sleeve and sleeve assembly do not interfere with each other, the tool wear can be suppressed and the service life is improved, while the operation is simple.
The socket wrench includes a body with a clamping portion at one end, an outer sleeve and a plurality of socket assemblies movably installed in the front-rear direction, in order to operate the outer sleeve and the plurality of socket 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 above-mentioned outer sleeve, an opening groove for providing a ratchet mechanism and communicating with the opening, and an integrally formed extension located in front of the opening groove. The stepped portion is formed with a locking hole and a ratchet setting groove respectively on the open groove, 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, and the outer sleeve has The concave and convex portions are integrally formed along the inner side, the fitting recess of the sleeve assembly and the sawtooth portion are integrally formed along the outer upper portion. The front and rear adjustment members are composed of an action lever and an adjustment knob connected to the action lever. On the action lever The upper part is integrally formed with an extended end part having an elliptical cross-section extending in the inner and outer direction. The socket wrench has a cylindrical part with a plurality of elastic restraining grooves and a rear central axis. While forming one body, the socket wrench is An extension is formed on the adjustment knob.
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 one with black coating and the other with 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 cylinder. The inner hexagons of the socket are arranged in order according to the model of the bolt, which can be customized as needed. Select.
