Abstract

The present invention relates to the field of wrenches, and in particular to an adjustable multifunctional wrench. The adjustable multifunctional wrench comprises a handle body; a first round end and a second round end are formed at the two ends of the handle body respectively; a grooved counterbore is formed in the first round end, a light-emitting diode (LED) light ring is embedded in the grooved counterbore, a turntable with a through hole is also embedded along one side of the first round end, a plurality of mutually-tangent adjusting blocks are disposed in the turntable, and one hexagonal open hole for matching a nut is formed at the center of each adjusting block; the second round end is also provided with a hanging hole, and the handle body is movably connected with a screwdriver through a rotating shaft. The nuts with different diameters can be adjusted by means of the turntable and the adjusting blocks, so time wasted in a workshop is greatly reduced, and time and labor are saved; through arrangement of the screwdriver, a user can fasten the remaining screws conveniently while fastening the nuts; the arrangement of the grip conforms to ergonomics, and the grip achieves an anti-sliding effect.

Description

ADJUSTABLE MULTIFUNCTIONAL WRENCH

BACKGROUND

Technical Field

The present invention relates to the field of wrenches, and in particular to an adjustable multifunctional wrench.

Related Art

At present, existing wrenches are single in structure. Some wrenches can only be used for screws or nuts with one specification, so that workers’ working efficiency is greatly reduced, and production progress is reduced.

Summary

Against the aforementioned shortcomings in the prior art, the objective of the present invention is to provide an adjustable multifunctional wrench.

In order to achieve the aforementioned objective, the following technical solution is adopted according to the present invention:

An adjustable multifunctional wrench, comprising a handle body; a first round end and a second round end are formed at the two ends of the handle body respectively; a grooved counterbore is formed in the first round end, a light-emitting diode (LED) light ring is embedded in the grooved counterbore, a turntable with a through hole is also embedded along one side of the first round end, a plurality of mutually-tangent adjusting blocks are disposed in the turntable, and one hexagonal open hole for matching a nut is formed at the center of each adjusting block; the second round end is also provided with a hanging hole, and the handle body is movably connected with a screwdriver through a rotating shaft.

Preferably, the handle body (3) is also provided with scales, a grip for being held by fingers is also positioned on the outer side of the handle body, and the grip is a rubber grip.

Preferably, the handle body is also provided with a locking block causing the turntable to fail to rotate.

Preferably, the handle body is further provided with an LED switch for starting or shutting down the LED light ring.

By adoption of the aforementioned solution, in the present invention, the turntable and the adjusting blocks are utilized to fasten nuts with different diameters, so time wasted in a workshop is greatly reduced, and time and labor are saved; through arrangement of the screwdriver, a user can fasten the remaining screws conveniently while fastening the nuts; the arrangement of the grip conforms to ergonomics, and the grip achieves an anti-sliding effect.

Brief Description of Drawings FIG. 1 is a structural schematic diagram of the present invention; FIG. 2 is a structural schematic diagram of pulling out a screwdriver in the present invention; FIG. 3 is a front view of FIG. 1 ; and FIG. 4 is a schematic diagram of replacing an adjusting block in a working state according to the present invention.

Description of Embodiments

Embodiments of the present invention are described in detail below by combination with accompanying drawings, but the present invention can be implemented by multiple different modes limited and covered by the claims.

As shown in FIG. 1 to FIG. 4, an adjustable multifunctional wrench provided by this present invention structurally comprises a handle body 3; a first round end 302 and a second round end 303 are formed at the two ends of the handle body respectively 3; a flange 301 is positioned on the surface of the first round end 302, and a grooved counterbore is formed in the first round end 302, an LED light ring 1 is embedded in the grooved counterbore, a turntable 10 with a through hole is also embedded along one side of the first round end 302, a plurality of mutually-tangent adjusting blocks 2 are disposed in the turntable 10, and one hexagonal open hole for matching a nut is formed at the center of each adjusting block 2; the second round end 303 is also provided with a hanging hole 7, and the handle body 3 is movably connected with a screwdriver 6 through a rotating shaft 5.

Thus, when the nut needs to be loosened, each adjusting block 2 performs tangent motion in the turntable 10 by the rotation of the turntable 10 until the diameter of the hexagon formed at the center of each adjusting block 2 is consistent with the diameter of the nut.

For convenience in adjustment, the handle body 3 is also provided with scales 8, a grip 9 for being held by fingers is also positioned on the outer side of the handle body 3, and the grip 9 is a rubber grip. Hand sliding of an operator can be avoided through arrangement of the grip 9 on the outer side of the handle body 3, and the grip 9 ensures force execution through ergonomics; through arrangement of the scales 8, the diameter and length of the to-be-loosened or to-be-tightened nut can be measured better, and thus the turntable 10 is adjusted better.

To fix the turntable 10, the handle body 3 is also provided with a locking block 11 causing the turntable 10 to fail to rotate. By pressing down the locking block 11, the turntable 10 cannot rotate, and thus the nut is adjusted.

In order that the wrench can also be used in a dark environment, the handle body 3 is also provided with an LED switch 4 for starting or shutting down the LED light ring 1.

What is described above is merely a preferred embodiment of the present invention and does not accordingly limit the patent scope of the present invention. Equivalent structures or equivalent process transformations which are performed by utilizing the specification and accompanying drawing contents of the present invention are directly or indirectly applied to other relevant technical fields and shall be included within the patent protection scope of the present invention in a similar way.
