Description

An adjustable hex wrench

technical field

The utility model relates to a tooling tool, in particular to an adjustable hexagonal wrench.

Background technique

A hex wrench is a commonly used installation and removal tool that uses the principle of leverage to turn bolts, screws, nuts, and other openings or sockets that hold bolts or nuts tightly. The hexagonal wrench is usually formed with an opening or a sleeve hole for clamping a bolt or a nut at one end or end of the handle. When in use, an external force is applied to the handle along the direction of thread rotation to twist the bolt or nut. Hexagonal wrenches are usually divided into dead wrench and live wrench. The dead wrench has a fixed-size opening at one or both ends for screwing nuts or bolts of fixed size; It can be adjusted to turn bolts or nuts of different specifications.

In the process of equipment maintenance, if dead wrenches are used, wrenches of different calibers need to be prepared, which are heavy to carry and inconvenient to use. And present common adjustable wrench is fixed jaw on one side, movable jaw on one side, moves movable jaw by thread transmission, thereby forms the jaw of different openings. However, when the adjustable wrench clamps the bolt or nut through the left and right sides, when turning in a certain direction, the force of applying pressure is concentrated on the corners of the bolt or nut, which is easy to cause damage to the corners of the bolt or nut. For example, there are edging phenomena such as the outer hexagonal round head. There are also some other multi-functional wrenches on the market that clamp bolts or nuts on multiple sides, but the structure is complex, the rigidity is poor, and the self-made is difficult and costly. During an emergency overhaul project or when time is of the essence, there is an urgent need for a less difficult homemade hex wrench tool that is practical.

Utility model content

The technical task of the utility model is to provide an adjustable hexagonal wrench for the above deficiencies in the prior art, with adjustable multi-apertures, which can quickly adapt to the calibers used according to the calibers of bolts and nuts on the maintenance equipment, and the structure Simple and easy to process, effectively reducing maintenance time and tool purchase costs.

The technical scheme for solving the technical problems of the utility model is: an adjustable hexagonal wrench, including a handle and a jaw connected as one; it is characterized in that: the jaw has a hexagonal large set of holes, and the large set of holes is through holes; one end of the jaw is fixedly connected to the handle, and there are bolt holes at the midpoints of the other five sides of the large hexagonal hole; there are matching adjusting bolts in each bolt hole, and the two are threaded; There are a plurality of hexagonal holes of different specifications on the handle described above.

Further, the above-mentioned adjustment bolt has a blocking piece at one end facing the hexagonal cavity of the jaw, and the diameter of the blocking piece is larger than the inner diameter of the bolt hole.

Further, the above-mentioned adjustable hexagon wrench is characterized in that: the hexagonal hole is a through hole.

Further, the above-mentioned adjustable hexagonal wrench is characterized in that: the closer the hexagonal hole is to the side of the jaw, the smaller the diameter is.

Compared with the prior art, the utility model has the following prominent beneficial effects:

1. According to the diameter of bolts and nuts on the maintenance equipment, multiple diameters can be selected and adjusted, which can quickly adapt to the diameter used, and quickly solve the phenomenon of shutdown and waiting for work caused by incomplete specifications of the hexagonal wrench during on-site maintenance, and improve maintenance operations. Efficiency, reduce procurement costs;

2. Integrated design, no loss of accessories, easy to carry and quick to use;

3. The clamping force of the bolt is strong, and it is not easy to cause the nut to be bald;

4. The structure is simple, the processing cost is low, and it is easy to popularize.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments of the description. In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the disclosed embodiments. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

In the following embodiments, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connection, or integration; it can be mechanical connection, electrical connection, or communication; it can be direct connection or indirect connection through an intermediary, it can be the internal communication of two components or the interaction of two components relation. Those of ordinary skill in the art can understand the specific meanings of the above terms in the embodiments of the application of the utility model according to specific situations.

It is to be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "Right", "Vertical", "Horizontal", "Top", "Bottom", "Inner", "Outer", "Clockwise", "Counterclockwise", "Axial", "Radial", " The orientation or positional relationship indicated by "circumferential", "end", "side", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiment of the utility model application and simplifying the description, rather than indicating or implying The devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the embodiments of the present application.

As shown in Figure 1, the utility model is an adjustable hexagonal wrench, which includes a handle 1 and jaws 2 which are connected as one.

Described jaw 2 has hexagonal large sleeve hole 3, and large sleeve hole 3 is a through hole.

One end of the jaw 2 is fixedly connected to the handle 1, and there are bolt holes at the midpoints of the other five sides of the large hexagonal hole 3. Matching adjusting bolts 4 are arranged in each bolt hole, and the two are threaded. In the optimized solution, in order to prevent the dislodgement, the adjustment bolt 4 has a blocking piece at one end facing the hexagonal cavity of the jaw 2, and the diameter of the blocking piece is larger than the inner diameter of the bolt hole.

There are a plurality of hexagonal holes 4 of different specifications on the handle 1, which are through holes in this embodiment, which can reduce the weight of the utility model, and can also be blind holes. In this embodiment, there are six hexagonal holes 4 , and the closer the hexagonal holes 4 are to the jaws 2 , the smaller the diameter is.

When using, take the nut 5 as an example, the 6 commonly used standard sleeve holes at the handle 1 (pictured A, B, C, D, E, F) are used first, and if there is no suitable size and caliber, use the 2 jaws. After inserting the large set hole 3 (shown G) at the hexagonal end, adjust the position of the 5 adjusting bolts 4 back and forth, and tighten the nut 5 to use as a normal wrench.

It should be noted that the parts not described in detail in this embodiment are well-known technologies in the art.

The above is only a specific embodiment of the utility model for the purpose of describing the utility model in detail.
