Description

[Detailed explanation of the idea] The present invention relates to tools.

Tools used in automobiles and the like come in various sizes, and small tools are especially easy to lose.

Therefore, the inventor intended to have a large tool support a small tool in a detachable manner, thereby preventing the small tool from being lost.
In particular, they focused on the shape of the spanner and devised a support structure that takes advantage of the shape and is easy to attach and detach manually, yet does not easily come off due to natural forces such as vibrations.

The present invention will be described below with reference to embodiments shown in the drawings.

This invention uses a large spanner 1 and a small spanner 2 as large tools.
is locked at two places, one of which is connected to the rotation locking means A.
and the other is locked by drop locking means B, respectively.

The rotation locking means A has a locking structure that allows the small spanner 2 to be removed only when the small spanner 2 is at a certain angle with respect to the large spanner 1, and in the embodiment, the large spanner 2 An elongated hole 4 extending in the axial direction of the arm (an insertion hole for a locking piece 7 described below) is provided in the arm 3 of the arm 3, and a pin 6 is provided protrudingly in the arm 5 of the small spanner 2, and a pin 6 is provided at the tip of the arm 3. A locking piece 7 having a shape corresponding to the elongated hole 4 is arranged such that its longitudinal direction is perpendicular to the axis of the arm 5.

Such rotation locking means A is made by inserting the piece 7 of the small spanner 2 into the elongated hole 4 of the large spanner 1 with the large spanner 1 and the small spanner 2 at right angles to each other, and then inserting the small spanner 2 into the long hole 4. If the small spanner 2 is rotated to be parallel to the large spanner 1, that is, the small spanner 2 is rotated at a predetermined angle to the attachment position to the large spanner 1, then the piece 7 of the small spanner 2 will be parallel to the large spanner 1. It is locked on the opposite surface of the arm 3, and there is no possibility that the small spanner 2 will separate from the large spanner 1.

Note that the elongated hole 4 may be provided in the small spanner 2 and the piece 7 may be provided in the large spanner 1.

The drop locking means B is used only when the small spanner 2 and the large spanner 1 are in a parallel state.
The locking structure is such that the small spanner 2 can be attached and detached from the large spanner 1 in the vertical direction, and the small spanner 2 is restrained to the large spanner 1 by the reaction force of the elastic body. An elastic stopper 9 that protrudes from the surface of the retaining piece 8 is disposed at the tip of the retaining piece.

This elastic stopper 9 has a hole 10 formed in the retaining piece 8, a ball 11 serving as a stopper is buried in the hole so as to be freely retractable, and a spring 12 serving as an elastic body is inserted between the ball 11 and the hole 10.
It is an interposed.

Such a dropping locking means B is such that when the small spanner 2 is lowered toward the large spanner 1 while being parallel to the large spanner 1, the working recess 13 of the small spanner 2 moves into the large spanner 1.
It hits the elastic stopper 9 of the retaining piece 8, pushes away the ball 11 of the stopper, passes there, and is fixed on the arm 3.

When the working recess 13 of the small spanner 2 passes the ball 11 of the elastic stopper 9, the ball 11 again protrudes from the retaining piece 8, preventing the small spanner 2 from separating from the large spanner 1.

The tool shown in the above embodiment is usually stored in a state in which a small spanner 2 is supported by a large spanner 1, and the large spanner 1 is used in this state.

When using the small spanner 2, first pull the working recess 13 side of the small spanner 2 away from the large spanner 1 and remove it from the engagement piece 8, then place the small spanner 2 9 against the large spanner 1.
When the small spanner 2 is rotated 0 degrees and the entire small spanner 2 is pulled away from the large spanner 1 at that position, the piece 7 of the small spanner 2 is attached to the large spanner 1.
The small spanner 2 is completely separated from the large spanner 1 by being removed from the elongated hole 4.

After using the small spanner 2, the above separation procedure is reversed to attach the small spanner 2 to the large spanner 1.

In the above embodiment, a ring spanner with a box spanner 14 at one end is used as the large tool 1, and a single-ended open spanner is used as the small spanner 2, but the point is that the large tool has a relatively thin arm. The necessary requirements are that the wrench is large enough to be stored in the arm part as a small spanner, and therefore large tools are not limited to spanners, and small spanners can also be used as both loss spanners, A ring spanner may also be used.

The tool according to the present invention takes advantage of the fact that the small spanner always has an operating recess, and locks it by dropping it at one end of the small spanner, and rotationally locks it at the other end of the small spanner. It is extremely easy to attach and detach manually, there is no risk of it coming off easily due to natural forces such as vibration, and the number can be confirmed by attaching a small spanner to a large tool when storing the tool. Losing the spanner can be prevented.

Moreover, the tool according to the present invention can reduce the storage space for the tool by attaching a small spanner to the large tool.
