Description

All-in-one driver bit case {INTEGRATED DRIVER BIT CASES}

The present invention relates to an integrated driver bit case. In more detail, the rotating shaft part and the bit part are provided with grooves that are recessed so that the inclined protrusion protruding toward the inside passes through, and when the rotating shaft part is rotated counterclockwise, the inclined protrusion is separated from the groove. do. Due to this feature, the bit part can be fixed and removed from the coupling part with minimal operation.

In general, screws are the most important basic parts of fastening elements among numerous parts used for various mechanical devices and civil engineering works, and are used as fastening means between fastening objects.

In order to perform a fastening operation using such a fastening means, fastening tools such as a screwdriver and a wrench are required.

The fastening means used for fastening work vary in shape and size depending on the purpose and use.

Therefore, a worker who performs work using the fastening means must prepare a fastening tool corresponding to the fastening means of various shapes.

As a typical fastening tool, a screwdriver for tightening or loosening a screw is provided.

A screwdriver is a fastening tool with a bit corresponding to the screw head having a straight or cross-shaped groove. You can tighten or loosen the screw by aligning the screwdriver bit to the head of the screw and rotating it. have.

Accordingly, the conventional screwdriver is composed of bits of various shapes corresponding to the screw shape and a handle capable of replacing and rotating these bits.

However, since the conventional manual screwdriver is fastened or loosened only by the rotational force of the worker, the rotation torque is different for each worker, and it is difficult to increase the rotation torque.

In addition, when a large amount of fastening work is required, there is a problem in that the fatigue of the worker is increased and the work productivity is decreased due to excessive work time.

In order to solve these problems, an electric driver has been disclosed to improve operator convenience.

However, the conventional electric driver is relatively large in size and heavy in weight compared to a manual screw driver, and thus there is a disadvantage in that work fatigue is easily generated.

In addition, since each bit corresponding to each screw head type must be separately carried, and then the carried bit must be brought and replaced, not only the work preparation time is increased, but there is also a problem of loss for separate storage.
