Technical Field

The invention relates to a multifunctional wrench, and belongs to the technical field of mechanical accessories.

Background

When carrying out machining assembly or maintenance, because the standard component size is various, the instrument that consequently adopts is in large quantity, like interior hexagonal spanner, outer hexagonal spanner, during assembly or maintenance, often needs to be changed, not only needs to expend time and seeks the instrument, moreover, the change instrument also can expend time, reduces work efficiency.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the multifunctional wrench has the advantages that the defects of the prior art are overcome, the multifunctional wrench integrates a plurality of inner angle wrenches and outer angle wrenches, the multifunctional wrench is simple in structure, convenient to carry and use, the time for finding replacement tools is saved, and the working efficiency is improved.

The multifunctional wrench comprises a base plate, wherein a center outer angle wrench is arranged in the center of the base plate, at least 6 inner angle wrenches are arranged on the periphery of the base plate in an outward extending mode, and an outer angle wrench is arranged between every two adjacent inner angle wrenches.

Working process or working principle:

the size of the central outer angle wrench and the size of the rest outer angle wrenches can be set according to actual needs, and the inner angle wrench can also be set into a plurality of corresponding models according to actual needs, so that the central outer angle wrench is convenient to assemble or maintain.

Preferably, two outer angle wrenches are staggered between two adjacent inner angle wrenches. The structure space is more fully utilized, the structural design is more reasonable, the number of tools is reasonably increased, and the application range of the invention is wider.

Preferably, the inner angle wrench is in a shape of a straight prism, a frustum of a pyramid, or an arc frustum of a pyramid. A plurality of interior angle spanners can be respectively arranged with different shapes, and the application range is wider.

Preferably, the inner corner key is disposed around the central outer corner key. Compact structure, portability and convenient use in operation.

Compared with the prior art, the invention has the beneficial effects that:

1. the invention basically arranges a plurality of external angle wrenches and internal angle wrenches, integrates a plurality of internal angle wrenches and external angle wrenches into a whole, realizes the combination of multiple tools, has simple structure, convenient manufacture, easy operation, convenient use and convenient carrying, saves the time for searching for replacing tools and improves the working efficiency.

2. The problem that the number of adopted tools is large due to the fact that standard parts are large in size when machining assembly or maintenance is conducted is solved, and working efficiency is improved; the problem that the long-term efficiency of mechanical assembly and maintenance time of various tools is not high is solved.

Detailed Description

The technical solution in the embodiments of the present invention will be further clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention:

example 1

As shown in fig. 1, the multifunctional wrench of the present invention comprises a base plate 15, a central outer corner wrench 13 is disposed in the center of the base plate 15, at least 6 inner corner wrenches are disposed on the outer periphery of the base plate 15 in an outward extending manner, and an outer corner wrench is disposed between two adjacent inner corner wrenches.

Two outer angle wrenches are arranged between two adjacent inner angle wrenches in a staggered mode.

The inner angle wrench is in a shape of a straight prism, a frustum of a pyramid or an arc frustum of a pyramid. A plurality of interior angle spanners can be respectively arranged with different shapes, and the application range is wider.

The inner corner key is arranged around the central outer corner key 13. Compact and small structure, convenient processing and manufacturing, convenient carrying and convenient use in operation.

Surrounding the central outer corner wrench, an inner corner wrench A1, an inner corner wrench B3, an inner corner wrench C5, an inner corner wrench D8, an inner corner wrench E10 and an inner corner wrench F12 are provided.

An outer angle wrench A2 is arranged between the inner angle wrench A1 and the inner angle wrench B3.

An outer angle wrench B4 is arranged between the inner angle wrench B3 and the inner angle wrench C5.

An outer angle wrench C6 and an outer angle wrench D7 are arranged between the inner angle wrench C5 and the inner angle wrench D8, and the outer angle wrenches C6 and the outer angle wrenches D7 are arranged in a staggered mode. The structure space is more fully utilized, the structural design is more reasonable, the number of tools is reasonably increased, and the application range of the invention is wider.

An external angle wrench E9 is arranged between the internal angle wrench D8 and the internal angle wrench E10.

An outer angle wrench F11 is arranged between the inner angle wrench E10 and the inner angle wrench F12.

An outer angle wrench G14 is arranged between the inner angle wrench A1 and the inner angle wrench F12.

The multifunctional wrench is formed by cutting a 45-cm-thick steel plate according to a specified pattern by a wire cutting machine. The size assembly and disassembly of the type threads of the outer hexagon bolts M18, M18, M16, M14, M12, M10, M8, M6 and M5, the type threads of the inner hexagon bolts M12, M10, M8 and M6 and the like can be realized.

And after cutting, polishing to reach the specified size. In order to achieve sufficient hardness, it is subjected to a quenching treatment.

And finally, performing rust prevention treatment on the product, and standing for a long time to rust.

All aspects needing scribing such as machining maintenance and the like.

The description of the directions and the relative position relationship of the structures in the present invention, such as the description of the front, the back, the left, the right, the upper and the lower, does not limit the present invention, and is only for the convenience of description.
