Description

Technical Field

[0001] The utility model belongs to the technical field of wrench tools, in particular to an F-type wrench. Background Art

[0002] Currently, the most commonly used valve switches are typically round. However, over time, valves can rust, or employees can slip while operating them, making them difficult to turn. In the event of an emergency, this can easily lead to a major safety incident, posing a significant threat to life and property. Currently, an F-type wrench is commonly used. The two levers at the front of the wrench engage the spokes of the valve handwheel, and the handle is turned to rotate the valve handwheel, thereby opening and closing the valve.

[0003] The F-type valve wrench, named for its shape resembling the letter "F," is a common tool used on-site in chemical plants. However, when chemical production operators operate the handwheel of an F-type valve wrench, the handle often slips inward toward the valve core because the handwheel and the shoulder are located at different planes. This poses a significant safety hazard, especially when applying high torque to the handwheel. Existing solutions, such as a raised point on the wrench head or an inward curve at one end, fail to effectively prevent slippage.

[0004] Furthermore, existing F-type valve wrenches are only suitable for handwheel valves. Furthermore, the varying sizes of F-type wrenches currently in use make it difficult to use a single F-type wrench for opening and closing different valve types, requiring constant switching during use. Consequently, inspectors are burdened with carrying multiple wrenches. Summary of the Invention

[0005] The present invention aims to provide an F-type wrench to solve the problem that it is difficult to use a single F-type wrench to open and close different types of valves, resulting in the need to constantly switch between them during use. As a result, inspection personnel need to carry multiple wrenches, which is quite troublesome.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an F-type wrench, comprising a handle, a first clamping assembly and a second clamping assembly, characterized in that a group of elliptical through holes are provided on the handle to facilitate the first clamping assembly and the second clamping assembly to adjust the length of the clamping assembly, which is suitable for valves of different sizes. The first clamping assembly and the second clamping assembly are respectively installed in the elliptical through holes and connected by bolt threads. The first clamping assembly and the second clamping assembly have the same structure, the bolt is made of iron, and a magnet block is embedded in the handle.

[0007] Preferably, the first bracket assembly includes a stress-bearing rod and a rectangular bar. The rectangular bar is fixedly installed horizontally at either end of the stress-bearing rod. The rectangular bar is provided with threads and is installed in the elliptical through hole to limit the position.

[0008] Preferably, both the first bracket assembly and the second bracket assembly are provided with threaded anti-slip sleeves.

[0009] Preferably, an open collar is fixedly provided at the top of the handle, and a hexagonal collar is fixedly provided at the bottom of the handle, so as to facilitate the operation of valves of commonly used sizes.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The first bracket assembly and the second bracket assembly are designed to be adjustable and suitable for valves of different sizes. At the same time, a magnet block is provided to facilitate the disassembly and assembly of the first bracket assembly and the second bracket assembly. Compared with the prior art, the utility model has strong practicality and can be suitable for valves of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
