Description

Technical Field

[0001] The utility model relates to the technical field of knob devices, in particular to a high-strength combined bolt and nut knob device. Background Art

[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, or nuts. A wrench usually has an opening or hole at one or both ends of the handle for clamping the bolt or nut. When in use, external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.

[0003] Wrenches are usually made of structural steel of carbon or alloy materials. There are basically two types of wrenches: fixed wrenches and adjustable wrenches. Fixed wrenches include commonly used fixed wrenches, which can only be used with matching bolts and nuts. The adjustable wrenches commonly used at present mostly use the method of pushing the threaded block to rotate to adjust the size of the wrench opening. However, when tightening the bolts and nuts, two sets of tools need to be used to rotate in opposite directions at the same time, which wastes time, is inconvenient to exert force during use, and is inconvenient to use. The nut cannot be screwed off while fixing the bolt. Utility Model Content
