Abstract

The invention discloses an anti-explosion combination wrench with replaceable bayonets and relates to an anti-explosion wrench. An opening end (5) and a plum blossom end (9) are respectively arranged at two ends of a handle (6). The opening end (5) is provided with a jack (4). Raised lines (2) arranged on outer walls of two sides of a U-shaped connector clip (3) are connected with grooves (15) of the jack (4) in an inserting mode. A plurality of bayonets (1) of the U-shaped connector clip (3) are respectively in various sizes. The plum blossom end (9) is provided with a placing inlet (12). The periphery surface of an insertion cover piece (14) is connected with the placing inlet (12) in an inserting mode. A plurality of plum-blossom-shaped covering ports (8) of the insertion cover piece (14) are respectively in various sizes. Aluminium bronze or beryllium bronze is adopted as manufacture material quality. By the adoption of the plurality of the bayonets, in various sizes, of the U-shaped connector clip and the plurality of cover ports, in various sizes, of the insertion cover piece, the fact that the tool quantity is effectively reduced in operation is achieved.

Description

【Technical field】 [0001] The invention relates to an explosion-proof wrench, in particular to an explosion-proof dual-purpose wrench with a replaceable bayonet socket. 【Background technique】 [0002] As is known, the explosion-proof wrench is mainly made of aluminum bronze and beryllium bronze, and no sparks will be generated during the use of aluminum bronze and beryllium bronze, so that it can be used in petroleum, chemical industry, mining, coal mine, gas extraction, power generation, metallurgy, aviation, storage, etc. Transportation, pharmaceuticals, gas, plastics, leather, pyrotechnics, firecrackers and other industries with explosion-proof requirements for special industries, among which the explosion-proof performance of beryllium bronze is suitable for working in hydrogen with a concentration below 21%; the explosion-proof performance of aluminum bronze is suitable for the concentration of 7.8%. Work in the following ethylene gas; in order to accurately clamp screws...
