There is a four-sided opening 3 for elastic φ34 nuts on a round head perpendicular to the narrow handle, and a hexagonal hole 2 for elastic φ19mm nuts inside, and a hexagonal hole for elastic φ9mm nuts at the junction of the round head and the narrow handle 4. There is an inner hexagonal groove 1 outside the round head of the extension line of the center line of the narrow handle; on the narrow handle, there are hexagonal holes 5 for elastic φ10mm nuts, hexagonal holes 5 for elastic φ11mm nuts, and elastic The hexagonal hole 6 for the φ12mm nut, the hexagonal hole 8 for the elastic φ16mm nut; two round heads at one end, the hexagonal hole 9 for the elastic φ6mm nut and the elastic φ8mm nut on the extension line of the center line of the narrow handle of the round head that meets the narrow handle The hexagonal hole 12 of the narrow handle centerline extension line is perpendicular to the four-side opening 10 of the elastic φ14mm nut and the four-side opening 11 of the elastic φ22mm nut; on the extension line of the narrow handle centerline of the second round head The square hole 15 of supporting sleeve head is arranged on, has the four sides opening 13 of elastic φ 24mm nut outwards with narrow bar handle centerline extension line vertical direction, and this opening has the hexagonal hole 14 of elastic φ 17mm nut inward.

Nuts, bolts, inner hexagons, slotted screws, Phillips screws and socket wrenches can be assembled and disassembled on it.

in:

Inner hexagonal groove 1 is an inner hexagonal column groove with a built-in magnet, which can be externally connected with an inner hexagonal wrench, a flat head, and a Phillips screw head (see Figure 3);

The square hole 15 of the matching socket head can be used as a socket wrench after the socket head is installed (see Figure 4).

In order to overcome the deficiencies of existing tools for installing and removing bolts and nuts, the utility model provides a multifunctional wrench, which can conveniently, quickly and accurately install and remove bolts and nuts, and solves the problems of inconvenient carrying and easy loss during construction. , It also improves the work efficiency and brings great convenience to the construction.

The utility model has the following characteristics:

1 The wrench has multiple functions;

2 Small and exquisite, novel style, easy to carry;

3 Simple and fast operation;

4 High work efficiency.

Detailed ways

Embodiment. This example is an experimental prototype, and its structure is shown in Figure 1-Figure 4. It is a kind of narrow bar handle in the middle, one of the two ends is two round heads connected in series with the narrow bar handle, and one end is a round head wrench. There is a four-sided opening 3 with an elastic φ34 nut on a round head perpendicular to the narrow handle, and a hexagonal hole 2 with an elastic φ19mm nut inside, and a hexagonal hole with an elastic φ9mm nut at the junction of the round head and the narrow handle. 4. There is an inner hexagonal groove 1 outside the round head of the extension line of the center line of the narrow handle; on the narrow handle, there are hexagonal holes 5 for elastic φ10mm nuts, hexagonal holes 5 for elastic φ11mm nuts, and elastic The hexagonal hole 6 for the φ12mm nut, the hexagonal hole 8 for the elastic φ16mm nut; two round heads at one end, the hexagonal hole 9 for the elastic φ6mm nut and the elastic φ8mm nut on the extension line of the center line of the narrow handle of the round head that meets the narrow handle The hexagonal hole 12 of the narrow handle center line is perpendicular to the extension line of the center line of the narrow handle, and the four side openings 10 of the elastic φ14mm nut and the four side openings 11 of the elastic φ22mm nut are respectively opened outwards; The square hole 15 of supporting sleeve head is arranged on, has the four sides opening 13 of elastic φ 24mm nut outwards with narrow bar handle centerline extension line vertical direction, and this opening has the hexagonal hole 14 of elastic φ 17mm nut inward.
