Abstract

PROBLEM TO BE SOLVED: To reduce trouble and loss of time for bit replacement during work using an electric drill.SOLUTION: An electric drill on the market is applied and used for a structure, and a drill having the same functions is provided on the opposite side from the other drill to allow one structure to serve as two drills. A drill-dedicated bit is attached to one drill, and a screwdriver-dedicated bit is attached to the other, so that the bits are not replaced in work using the same size and a replacement time for the bits can be shortened.

Description

This invention applies a commercially available drill structure, has the same structural function on the opposite side of one drill tool, has two drills provided on the left and right, and can be started with alternating power and direct power Devised a drill, screwdriver.

In the current drill, drills and driver pits are replaced one by one, but in my devised “double-headed, AC / DC drill, driver” pits of the same size, the pits are not replaced during the same work. Can work.

Invention effect

If the drilling pit and screw tightening pit are set in advance during the same operation, the pit replacement work and labor can be reduced.

Displayed in FIG. 1 and FIG.
These are (structure, cross section, perspective view) of the overall view. These are (structure, cross section, see-through | perspective) figure of the 90 degree rotation figure of FIG.

This invention applies a commercially available electric drill structure, has the same structural function on the opposite side of one drill tool, has drills on the left and right, and has the function of two units, and can be started with alternating and direct power Devised a drill, screwdriver.

In the current drill, the drill, driver, and pit are replaced one by one, but in the “double-headed electric AC / DC drill and driver” that I devised, the pit is replaced with the same size pit during the same operation. You can work without

Invention effect

If the pit for hole hitting and screw tightening is set in advance during the same operation, pit replacement work and labor can be shortened.

Claims (8)

The power is used for both AC and DC (12V to 24V). The structure uses a commercially available electric drill, and a drill having the same function is provided on the opposite side of the current drill, so that one unit can use two roles. A drill pit is attached to one side and a driver pit is attached to the other side. During the same (size) operation, each bit is not exchanged, so the pit exchange time can be shortened. The newly installed drill and driver structure functions can be switched one by one by providing a clutch (ON, OFF). The outer cover case is made of reinforced plastic to further reduce the weight of the device. The pit size for drills and drivers should be up to ¢ 10mm. The fixed shaft of the pit is a three-point picking type, and is fixed by screwing. The name of the tool of the present invention is “double-headed dual-purpose drill, driver”.
