Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-held work tool wrench frequently used in daily life and production work.

[0002]

2. Description of the Related Art Conventionally, bolts are used during daily life and production work.
Working tools that are often used to tighten or loosen the nuts are a spanner, b wrench, c monkey, d socket wrench, and the like. However, aspects such as convenience, versatility and stability have various disadvantages and inconveniences as follows. Tightening or loosening the bolts will be described as an example. 1 It is convenient but lacks applicability. A spanner, b wrench and d socket wrench can be used immediately if they match the bolt size. It is not necessary to adjust the working size (mouth width), but instead, for bolts of different size, several bolts corresponding to the different size
You need to prepare a spanner, b wrench, and d socket wrench. It is necessary to switch depending on the size during work. Therefore, it is inconvenient to carry, and the efficiency is low because switching is performed. In other words, although there is the convenience of adjusting the size (mouth width), several pieces of different sizes need to be prepared. 2 Although it is versatile, it is inconvenient to adjust. Although c-monkeys can be used in different sizes within a certain range, it takes time to adjust the mouth width until they are exactly the same size. In addition, the same continuous rotation work as a spanner is not possible, and the efficiency is low. 3 Weak stability a The wrench a and wrench c have only two contact surfaces (relative surfaces) with the bolt, so the corners of the bolt head are easily crushed and easily displaced. Damage. Therefore, the stability is weak. It is narrow and difficult to use in deep places. As described above, none of the currently used tools such as a spanner, b wrench, c monkey, and d socket wrench have three aspects of simultaneous convenience, versatility, and stability.

[0003]

Accordingly, for about a hundred years, the above-mentioned drawbacks and inconveniences have not been solved, and the a wrench, b wrench, c monkey, d
Socket wrench is very inconvenient for the user. The present invention has been invented in order to meet the strong demands of such users, excluding the above-mentioned drawbacks and inconveniences. It has epoch-making significance.

[0004]

The present invention is a specific example of solving the actual problem by applying the following principle (natural law). Principle 1

FIG. 7 is a regular triangle formed by extension lines of three sides of an arbitrary regular hexagon at arbitrary equal intervals as in the principle diagram. That is, any regular hexagon always has a circumscribed regular triangle.
In addition, any regular triangle always has an inscribed regular hexagon. The three interior angles of all two equilateral triangles are equal and have a magnitude of 60 °. All three equilateral triangles are necessarily similar triangles. Due to the above properties, when one side of the equilateral triangle is translated, the constructed new triangle is an equilateral triangle. 4 Normal bolts (heads) and nuts are hexagonal prisms whose bottom and surface are regular hexagons. The angle at which the surfaces intersect is 120 °. That is, the size of one internal angle of the regular hexagon is 120 °. Using the above principle and taking the bolts as an example, the solution will be described with reference to the drawings.

As shown in FIG. 1, a lock device includes a lock slider 12 provided with a shaft 15 for freely rotating a worm 11, and a rack at a front portion of a handle having teeth meshing over a part of the circumference of the worm 11. It is composed of such parts. Unlock the worm 11 by sliding the slider 12 (b)

As shown in FIG. 1, at least one set of the main body has an angle of 6
A front portion having two fixed contact surfaces 1 at 0 ° and an opening which can be fitted to a bolt and a nut from one side of one of the two fixed contact surfaces having a set intersection angle of 60 °; The body is provided with a sliding groove 13 for guiding the entrance and exit of the locking slider 12 (a) on the rear side surface. (C)

As in FIG. 1, the handle surrounds the rotation axis and has a head provided with a third contact surface 3 which can rotate in a single direction within 90 ° and has a return spring 14 attached thereto, and a worm 11 of a slider 12.
Is formed of a gripper having teeth that mesh with and cover a part of the circumference of. The center line of the handle has two fixed contact surfaces 1
Are the bisectors of the corner where. When the lock is released, the handle can slide freely back and forth according to the sliding groove 9 of the handle of the main body. A highly efficient handy speedy wrench configured as described above.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the present invention is constructed as described above, the lock lever 16 for use is turned and the slider 12 is rotated.
When the handle 2 is turned to the outside by 90 ° to 270 ° with respect to the slider 12 after the lock is released, the worm 11 of the slider 12 is connected to a rack-like portion at the front of the handle 2. Separate from the meshing state. That is, handle 2
The lock for was released. After lowering the handle 2 and aligning the two fixed contact surfaces 1 where the wrench crosses at an angle of 60 ° with the two surfaces where the arbitrary crossing angle of the bolt is 60 °, the third contact surface 3 is bolted. Push the handle forward until it hits the third side of. After the three contacting surfaces of the wrench are exactly aligned with the three equally spaced surfaces of the bolt, the handle 2 is turned inward until it engages the worm 11 of the slider 12. Then, the locking lever 16 of the slider 12 is turned, locked, and then tightened. Since the head of the handle can be rotated only in a single direction within 90 ° and is provided with a return spring 14, the work can be continuously reciprocated without removing the wrench from the bolt. When loosening, turn the surface of the wrench, align it, and then loosen.

C The contact surfaces with the bolt and nut are three equally spaced surfaces with an angle of intersection of 60 °. Due to the fact that the triangle is the most stable shape, these three contact surfaces have the most stable configuration. Also, there is one more contact surface with the bolt and nut than the a spanner and c monkey. Therefore, the concentrated stress is dispersed in addition to the stability, and damage to the bolt and nut can be prevented. Can be tightened or loosened without any damage during operation. D Can be used quickly even in narrow and deep places. The necessary space (angle) is small. That is, as described above, the wrench has three aspects of simultaneous convenience, versatility, and stability, is convenient to carry, easy to use during work, and has high efficiency.
