FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a combination wrench includes: the wrench comprises a wrench head 1, a rotating shaft 2, a plurality of wrench sleeves 3 and a handle 4;

the wrench head 1 is a U-shaped structure made of a steel pipe or a steel plate, and through holes with opposite positions are arranged at two ends (namely opening ends) of the wrench head 1;

the rotating shaft 2 comprises a square or cylindrical main rod 6, two ends of the main rod 6 are respectively and fixedly connected with a screw 7, the rotating shaft 2 is arranged in the wrench head 1, two ends of the rotating shaft respectively penetrate through holes formed in two ends of the wrench head 1, and screw caps 5 are screwed at the end parts of two ends (namely the screw rods at the two ends) of the rotating shaft 2;

the wrench sleeves 3 are uniformly distributed along the circumference by taking the rotating shaft 2 as the center, the number of the wrench sleeves 3 is four, the number of the wrench sleeves 3 is the steel pipes with different pipe diameters, the inner cavities of the wrench sleeves 3 are machined into wrench holes with different specifications, and the wrench holes are square holes, hexagonal holes, triangular holes or circular holes and are used for being matched with the specifications of nuts to be screwed;

the handle 4 is a cylindrical barrel or a rectangular long plate, one end of the cylindrical barrel is fixedly connected with the bottom of the wrench head 1, and the other end of the cylindrical barrel is provided with a circular hanging hole 8.

And (3) processing and manufacturing the combined wrench:

1) according to the distance between the two ends of the U-shaped wrench head 1, a section of short-limb steel pipe is cut and processed, and the two ends of the short-limb steel pipe are plugged by steel plates to be used as a main rod 6;

2) a plurality of steel pipes with different pipe diameters are vertically welded on the outer wall of the center of the main rod 6 along the circumference to serve as wrench sleeves 3, inner cavities of the wrench sleeves 3 are processed into wrench holes with different specifications, and the wrench holes are square holes, hexagonal holes, triangular holes or circular holes;

3) a section of screw rod is respectively and vertically welded at the central part of the plugging steel plate at the two ends of the main rod 6 to be used as a rotating shaft 2;

4) a U-shaped wrench head 1 is welded and cut by adopting a steel plate, round through holes are symmetrically formed at the upper end parts of two vertical plates, and a rectangular handle 4 is additionally welded at the middle part of the bottom end of the two vertical plates;

5) a round hanging hole 8 is formed in the rectangular handle 4 close to the bottom end;

6) the screw rods at the two ends of the main rod 6 penetrate through the round through holes formed at the two ends of the U-shaped wrench head 1 and are fastened by the nuts 5, and the rotating shaft 2 can rotate, so that the combined wrench is processed and manufactured.

The using method comprises the following steps: the rotating shaft 2 is rotated according to the outer diameter of the nut to be screwed, the adaptive wrench sleeve 3 is sleeved on the nut to be screwed, force is applied to the handle 4 to achieve a loosening and fastening effect, and when the bolt distance is close or the force is applied inconveniently, the handle can be rotated by 90 degrees (in the horizontal and vertical directions) through the screw rotating shaft 2 +/-and then force is applied to achieve a maintenance and overhaul bolting effect.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model. It should be noted that other equivalent modifications can be made by those skilled in the art in light of the teachings of the present invention, and all such modifications can be made as are within the scope of the present invention.
