The first hammer head 1 includes a first wrench face 11 , and the second hammer head 2 includes a second wrench face 22 . The first wrench face 11 and the second wrench face 22 are parallel to and opposite to each other.

During the actual maintenance, installation and use, the staff can control the nut 5 to rotate on the screw rod 4, and push the second hammer head 2 on the nut 5 away from the first hammer head 1. The first wrench face 11 of the first hammer head 1 and the first hammer head 1 A certain space exists between the second wrench faces 22 of the two hammer heads 2 . At this time, the staff can hold the connecting handle 3 connecting the first hammer head 1, use the first hammer head 1, and realize the function of a multi-tool as a hammer through the first hammer head 1; and make the first hammer head 1 and the second hammer The space between the heads 2 is sandwiched with fixing screws and other structures, and by rotating the connecting handle 3, the function of using a multi-purpose tool as a wrench can be realized. It is easy to use and has a relatively simple structure, and the production cost is relatively low, and the staff can also adjust the nut 5 to rotate on the screw rod 4, so that the first wrench surface 11 of the first hammer head 1 and the first wrench of the second hammer head 2 can be adjusted. The surface 11 is completely fitted, the first hammer head 1 and the second hammer head 2 are used together as a hammer, when the first hammer head 1 and the second hammer head 2 are combined and the first hammer head 1 is used as a hammer alone, it can be used for different shapes. The multi-tool has strong versatility for maintenance and installation of the structure with the size.

And the first hammer head 1 and the second hammer head 2 are spaced apart, for some parts distributed at intervals, such as screw structures installed at intervals, the first hammer head 1 and the second hammer head spaced apart can also be used. 2. Binding two spaced screws at the same time is also conducive to improving the efficiency of maintenance and installation.

For ease of understanding, the A direction is marked in FIG. 1 , and all the length directions below are the A direction.
