Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a multifunctional wrench. Background Art

[0002] The F wrench is a common hand tool, mainly used to open and close various manual valves. It is named because its shape resembles the English letter "F", and is also called F-type wrench, valve wrench, F-type valve wrench, F valve wrench, etc. Commonly used F-type wrenches are mainly divided into round head F wrenches and square head F wrenches.

[0003] F wrenches are widely used in front-line workshops in industries such as petroleum, chemical industry, and metallurgy. However, due to the various sizes of front-line valves and the different types of valve handwheel outer edges, conventional F wrenches are difficult to fully meet the requirements of on-site use. In terms of design and application, conventional F wrenches have the following defects:

[0004] 1) Large application limitations: The opening size of the F wrench is fixed, and one F wrench is effective for all valves. For example, a small-opening F wrench is not suitable for opening and closing large valves, and a large-opening F wrench is not suitable for opening and closing small valves. If you need to open and close valves of different sizes, you usually need to carry multiple F wrenches with different opening sizes.

[0005] 2) Not suitable for opening and closing small and micro valves: For small and micro valves, such as 1 / 2-inch, 3 / 4-inch, 1-inch and other valves below 2 inches, the diameter of the valve umbrella-shaped handwheel is very small, and the opening of the F wrench is generally large. The F wrench cannot effectively hold the valve handwheel firmly, so it is not suitable for opening and closing small and micro valves.

[0006] 3) Easy to slip and poor stability: When using the F wrench, the friction between the wrench and the valve rim is insufficient, and the F wrench slips very seriously. Figure 1 As shown in the figure, unless the F wrench is stuck at the intersection of the spoke and the rim, it is very easy to slip when stuck at other positions of the rim. Utility Model Content
