One end of the handle is provided with a first counterbore whose diameter is larger than that of the screwdriver head, and the inner wall of the first counterbore is provided with a first elastic protrusion for fixing the screwdriver head, and one end of the screwdriver head is provided with a Two symmetrical grooves where the elastic protrusions engage;

The wrench bar is provided with a second counterbore for accommodating the screwdriver head, the depth of the second counterbore is greater than the length of the screwdriver head; the other end of the wrench bar is provided with a wrench head installation hole for installing the wrench head, A second elastic protrusion for fixing the wrench head is arranged on the inner wall of the wrench head mounting hole;

The plurality of wrench heads are cuboids matching the size of the wrench head installation holes, and through holes corresponding to nuts of different specifications are respectively arranged on them, and the outer walls of the plurality of wrench heads are provided with holes for engaging with the second elastic protrusions. groove, and one end of the wrench rod is provided with a cavity capable of accommodating several wrench heads.

Preferably, one end of the wrench rod and one end of the handle are threaded, and the threaded connection is tight and easy to assemble and disassemble.

Compared with the wrench adopted in the prior art, the beneficial effects of the utility model are as follows:

(1) Combining a wrench and a screwdriver can meet various needs at the same time, which is convenient and practical.

(2) Equipped with wrench heads of various specifications to meet the actual needs under different working conditions.

(3) Compact structure, easy installation and disassembly, easy to carry and use.

Those skilled in the art can fully understand the present invention without the description of these detailed parts.

As shown in Figures 1-2, they are respectively a schematic diagram of the explosion structure of a multifunctional combination wrench and a schematic diagram of the structure of several wrench heads according to the embodiment of the present invention, including a handle 10, a screwdriver head 20, several wrench heads 40 and a wrench rod 30 , the screwdriver head 20 and several wrench heads 40 are located in the wrench rod 30, and one end of the screwdriver head 20 and one end of the wrench rod 30 are connected to one end of the handle 10;

One end of the handle 10 is provided with a first counterbore whose diameter is greater than that of the screwdriver head 20. The inner wall of the first counterbore is provided with a first elastic projection for fixing the screwdriver head. Two symmetrical grooves for engagement;

The wrench rod is provided with a second counterbore for accommodating the screwdriver head, and the depth of the second counterbore is greater than the length of the screwdriver head; the other end of the wrench rod is provided with a wrench head installation hole for installing the wrench head, and the wrench head installation hole is provided on the inner wall. A second elastic protrusion for fixing the wrench head is provided;

Several wrench heads are cuboids matching the size of the wrench head installation holes, and through holes corresponding to nuts of different specifications are respectively arranged on them. The outer walls of the several wrench heads are provided with concave holes for engaging with the second elastic protrusions. One end of the wrench rod is provided with a cavity that can accommodate several wrench heads.

In the specific implementation process of the embodiment of the utility model, a suitable wrench head can be selected according to the actual situation, the wrench rod and the handle can be disassembled, the wrench head located in the cavity can be taken out, and the wrench head can be fixed on the wrench head installation hole.
