(2) The utility model discloses in, the connecting rod is perpendicular with the spanner, has both avoided the condition of hand clamp between wrench handle and wall when narrow space operation, is favorable to again through the connecting rod application of force, makes the bolt dismouting more simple and convenient laborsaving.

(3) The utility model discloses in, add chromium vanadium alloy element when the preparation, promoted intensity, corrosion resistance and the wearability of spanner work end, improved the life of spanner.

In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be described in further detail with reference to the drawings.

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:

FIG. 1 is a schematic view of a multi-function wrench;

wherein, 1, socket spanner, 2, box spanner, 3, connecting rod.

Detailed Description

The embodiments of the invention will be described in detail hereinafter with reference to the accompanying drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.

Referring to fig. 1, the present embodiment is applied to the dismounting and mounting of pipe bolts in a narrow space.

A multifunctional wrench comprises a socket wrench 1, a box wrench 2 and a connecting rod 3; the socket wrench 1, the box wrench 2 and the connecting rod 3 are integrally cast; one end of the axis of the connecting rod 3 is vertical to the axis of the socket wrench 1, and the other end of the axis of the connecting rod 3 is vertical to the axis of the box wrench 2; the axis of the socket wrench 1 is parallel to the axis of the box wrench 2.

In this embodiment, box spanner 1 is the long cylinder that one end was equipped with the cavity, is favorable to the spanner to stretch into narrow space and operates, and the inside cross-section of cavity is regular hexagon.

In this embodiment, box spanner 2 is L type structure, is favorable to the spanner to stretch into narrow space, avoids operator's hand to be in between wrench handle and the wall simultaneously, is favorable to the operation.

In this embodiment, 1 box spanner and 2 work ends of box spanner are made by chromium vanadium steel, have promoted the intensity and the wearability of work end, prevent that the spanner from wearing and tearing appear in the use, have promoted the life of spanner.

In this embodiment, the multipurpose wrench is made of carbon steel.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
