Description

Device for holding drill

More particularly, the present invention relates to a drill supporting apparatus which maintains an accurate vertical degree irrespective of a work position of a worker during a hole drilling operation of a hand drill, and which can be easily carried by an operator through a reduction in size and weight &Lt; / RTI >

Generally drills, especially hand drills, are devices for performing various drilling (drilling, reaming, tapping) on metal or non-metal workpiece surfaces.

When drilling with such a hand drill, the verticality (straightness) between the workpiece and the drill must be accurately maintained.

However, in general, when a worker drills a hole with a hand drill in an industrial field, there is a problem that the number of hole machining is large and the work posture of the worker is inconvenient according to the work environment, so that a constant vertical degree can not be accurately maintained.

If the perpendicularity between the workpiece and the drill is not maintained, errors in the dimension of the hole are generated. As a result, an assembly error occurs in the final structure, and if necessary, There is a problem that the manufacturing cost increases.

To solve this problem, a drill holding device has been developed.

However, in the conventional drill supporting apparatus, there is a problem that the drilling support apparatus must be operated separately in order to maintain the straightness in the hole drilling operation, thereby reducing the working efficiency.

Further, the conventional drill supporting apparatus has a problem in that it can not be used in some working environments of size cursors.

Further, the conventional drill supporting apparatus is complicated in structure and heavy in weight, so that the operator can carry it in order to use the drill supporting apparatus in a desired working position.

In addition, the conventional drill supporting apparatus has a complicated structure, has a large size, and has a problem of increased manufacturing cost.
