Description

Adjustable hexagonal spanner

Technical Field

The utility model relates to a frock tool, especially an adjustable hexagonal spanner.

Background

A hexagonal wrench is a common mounting and dismounting tool, and utilizes the lever principle to turn a bolt, a screw, a nut and other threads to tightly hold an opening or trepanning fastener of the bolt or the nut. The hexagonal wrench is generally provided with an opening or a trepan for holding a bolt or a nut at one end or a shank end of a shank, and when the hexagonal wrench is used, an external force is applied to the shank in a thread rotating direction to screw the bolt or the nut. The hexagonal wrench is generally divided into a dead wrench and an adjustable wrench, wherein the dead wrench is a nut or bolt with one end or two ends provided with an opening with a fixed size for screwing the nut or bolt with a fixed size; the adjustable wrench has an opening width which can be adjusted within a certain size range, and can be used for screwing bolts or nuts with different specifications.

In the process of equipment maintenance, if a dead wrench is used, wrenches with different calibers need to be provided, and the wrench is heavy to carry and inconvenient to use. At present, a common adjustable wrench has a fixed jaw at one side and a movable jaw at one side, and the movable jaw moves through thread transmission, so that jaws with different openings are formed. However, when the adjustable wrench grips the bolt or the nut through the left side and the right side, the force applied is concentrated on the edge of the bolt or the nut when the adjustable wrench rotates in a certain direction, which is easy to damage the edge of the bolt or the nut, such as the edge grinding phenomenon of the outer hexagon round head. Other multifunctional wrenches for clamping bolts or nuts on multiple surfaces are arranged on the market, but the structure is complex, the rigidity is poor, the self-control difficulty is high, and the self-control cost is high. In an emergency maintenance project or under the condition of urgent time, a practical hexagonal wrench tool with low self-control difficulty is urgently needed.

SUMMERY OF THE UTILITY MODEL

The technical task of the utility model is not enough to above prior art, provides an adjustable hexagonal spanner of one kind, and multiple aperture is adjustable, can be according to examining and repairing the used bore of bolt, nut bore size on the equipment, adaptation very fast to simple structure, workable effectively reduces repair time and multiplexer utensil purchasing cost.

The technical proposal of the utility model for solving the technical problem is that: an adjustable hexagonal wrench comprises a handle and a jaw which are connected into a whole; the method is characterized in that: the jaw is provided with a hexagonal large trepanning which is a through hole; one end of the jaw is fixedly connected with a handle, and bolt holes are formed in the middle points of the other five edges of the hexagonal large sleeve hole; each bolt hole is internally provided with an adaptive adjusting bolt which is in threaded connection with the bolt hole; the handle is provided with a plurality of hexagonal holes with different specifications.

Furthermore, a baffle plate is arranged at one end of the adjusting bolt facing the jaw hexagonal cavity, and the diameter of the baffle plate is larger than the inner diameter of the bolt hole.

Further, foretell adjustable hexagonal spanner, its characterized in that: the hexagonal hole is a through hole.

Further, foretell adjustable hexagonal spanner, its characterized in that: the diameter of the hexagonal hole is smaller as the hexagonal hole is closer to the jaw side.

Compared with the prior art, the utility model discloses following outstanding beneficial effect has:

1. the multi-aperture adjustable type maintenance device has the advantages that the multi-aperture is selectable and adjustable according to the aperture sizes of the bolts and the nuts on the maintenance device, the used aperture can be quickly adapted, the phenomena of shutdown and waiting for work caused by the fact that the specifications of the hexagonal wrenches are not uniform in field maintenance are quickly solved, the maintenance operation efficiency is improved, and the purchase cost is reduced;

2. the integrated design can not cause the loss of accessories, and is convenient to carry and quick to use;

3. the clamping force of the bolt is high, and bald edges of the nut are not easy to cause;

4. simple structure, low processing cost and convenient popularization.

Detailed Description

The invention is further described with reference to the drawings and the detailed description. In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the claimed embodiments. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

In the following embodiments, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.

It is to be understood that the terms "central," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," "end," "side," and the like are used in an illustrative and non-restrictive sense, and are used in a generic and descriptive sense only and not for purposes of limitation, the referenced devices or elements must be in a particular orientation, configuration or operation, and not for purposes of limitation, as the orientation or positional relationship is illustrated in the figures.

As shown in fig. 1, the utility model relates to an adjustable hexagonal wrench, which comprises a handle 1 and a jaw 2 connected into a whole.

The jaw 2 is provided with a hexagonal large trepanning 3, and the large trepanning 3 is a through hole.

One end of the jaw 2 is fixedly connected with the handle 1, and bolt holes are formed in the other five middle points of the hexagonal large sleeve hole 3. In each bolt hole there is a matching adjusting bolt 4, which are screwed together. In the optimization scheme, in order to prevent the separation, a baffle is arranged at one end of the adjusting bolt 4 facing the hexagonal cavity of the jaw 2, and the diameter of the baffle is larger than the inner diameter of the bolt hole.

Handle 1 on have the hexagonal hole 4 of a plurality of different specifications, for the through-hole in this embodiment, can reduce the utility model discloses a weight also can be for the blind hole. In the present embodiment, the number of the hexagonal holes 4 is 6, and the diameter of the hexagonal holes 4 is smaller as they approach the jaw 2.

When the spanner is used, taking the nut 5 as an example, 6 common standard trepanning holes (shown in figures A, B, C, D, E and F) at the handle 1 are preferably sleeved, if the caliber does not have a proper size, the large trepanning hole 3 (shown in figure G) at the hexagonal end at the jaw 2 is used, after the standard trepanning holes are sleeved, the positions of 5 adjusting bolts 4 are adjusted back and forth, and the spanner can be used according to a normal spanner after the nut 5 is tightened.

It is to be noted that the present embodiment is not described in detail, and is a technique known in the art.

While certain embodiments of the present invention have been described above for purposes of illustration, it will be apparent to those skilled in the art that various obvious changes may be made without departing from the spirit and scope of the invention.
