Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a multifunctional foldable wrench. 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, nuts and other threaded fasteners with openings or holes. Wrenches are usually made of structural steel of carbon or alloy materials. Wrenches usually have openings or holes for clamping bolts or nuts at one or both ends of the handle. When in use, external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.

[0003] Based on the above, the inventors have found the following problems: existing wrenches are often unable to install and remove screws of different sizes and shapes, so multiple wrenches need to be prepared; existing wrenches are often more laborious to install and remove screws due to their short length, and are not convenient to use in narrow places such as walls and corners.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a multifunctional folding wrench is provided to achieve the purpose of having more practical value. Utility Model Content

[0007] Furthermore, the shape of the lower groove is consistent with that of the upper groove, the inner diameter of the lower groove is smaller than that of the upper groove, and the shapes of the upper groove and the lower groove can engage nuts of different sizes.

[0008] The beneficial effect of adopting the above further solution is that the upper groove and the lower groove of the same shape but different diameters can be used to disassemble and install nuts of different sizes through the serrations provided on their inner walls.

[0009] Furthermore, the arc-shaped protrusion can function as a bottle opener and can be used to open lids of various containers.

[0010] Furthermore, the vertical block can be regarded as a slotted screwdriver for removing the slotted nut.

[0011] Furthermore, the diameter of the No. 1 regular hexagonal slot is larger than that of the No. 2 regular hexagonal slot, and the No. 1 regular hexagonal slot and the No. 2 regular hexagonal slot can be used to remove regular hexagonal screws.

[0012] The beneficial effect of adopting the above further scheme is that the arc-shaped protrusion can act as a bottle opener and can be used to open various container lids. The vertical block can be regarded as a flat-blade screwdriver for opening flat-blade nuts. The No. 1 regular hexagonal slot and the No. 2 regular hexagonal slot can be used to open regular hexagonal screws, thereby increasing the use scenarios of the multifunctional folding wrench.

[0013] Furthermore, when using the lower wrench, the upper wrench can be rotated around the bolt at any angle from ten degrees to one hundred and eighty degrees according to the usage, and the gripping point of the upper wrench can be used as a force point, and vice versa when using the upper wrench.

[0014] The beneficial effect of adopting the above further scheme is that the upper wrench and the lower wrench can be rotated to any angle as needed when opened, which is convenient for installing and removing nuts. When using the upper slot or the lower slot, the length of the multifunctional foldable wrench can be extended by rotating the lever principle to save manpower. Compared with ordinary wrenches, the multifunctional foldable wrench can be used arbitrarily in narrow places such as walls and corners.

[0015] The beneficial effects of the utility model are as follows: the utility model obtains a multifunctional folding wrench through the above design, the slots provided on the upper wrench and the lower wrench can be used to install and disassemble nuts of different sizes, and by providing a bolt, the upper wrench and the lower wrench can rotate around the bolt, and when using the upper slot or the lower slot, the length of the multifunctional folding wrench can be extended by rotation using the lever principle, which can save manpower. Compared with an ordinary wrench, the multifunctional folding wrench can be used arbitrarily in narrow places such as walls and corners, and is convenient for installing and disassembling nuts and screws. The arc-shaped protrusion can play the role of a bottle opener and can be used to open various container covers. The vertical block provided on the lower wrench and the No. 1 regular hexagonal slot and the No. 2 regular hexagonal slot can be used to install and disassemble regular hexagonal nuts of different diameters. The above parts increase the usage scenarios of the wrench, making the folding wrench multifunctional. BRIEF DESCRIPTION OF THE DRAWINGS
