Description

Multifunctional wrench tool

Technical Field

The application relates to a multifunctional wrench tool, and belongs to the technical field of pipeline tools.

Background

With the popularization of town gas and the large-scale implementation of the 'coal to gas' engineering in various places throughout the country, the number of gas users is greatly increased, and in the inspection and maintenance of natural gas equipment, a large number of inner hexagonal bolts and outer hexagonal bolts are arranged in the pressure regulator, so that two spanner tools are required to be frequently replaced, and the working efficiency of maintainers is reduced. In general, a wrench in the prior art can only replace an inner hexagonal bolt or an outer hexagonal bolt, for example, chinese patent publication No. CN215240516U mentions a multifunctional wrench tool, which is characterized in that a rectangular base plate is fixedly connected to an end portion of a handle, a first cavity is formed in the base plate, a second cavity communicated with the first cavity is formed in the handle, two first fixing arms arranged in parallel are fixed on the base plate, and a second fixing arm perpendicular to the first fixing arm is provided, so that workpieces of various sizes can be replaced through adjustment between the two fixing arms, but workpieces of two different types cannot be replaced at the same time. Therefore, a new wrench tool is a problem to be solved by those skilled in the art.
