The present invention relates to an electrical drill equipped with a laser vertical and horizontal module. In more detail, the present invention relates to an electrical drill equipped with a laser vertical and horizontal module in which a weight of the laser vertical and horizontal module installed in the electrical drill constantly indicates the center of the earth to maintain the electrical drill in vertical and horizontal states even if a user inclines the electrical drill. The electrical drill equipped with the laser vertical and horizontal module has a structure in which the laser vertical and horizontal module is installed at the front of a convention electrical drill. The laser vertical and horizontal module includes a laser vertical measuring unit provided vertically and a laser horizontal measuring unit provided laterally. The laser vertical and horizontal measuring units include a power supply part, a laser diode, and a lens for collecting a dispersed laser beam in the form of a laser having a linearity property. The weight is installed at a lower portion of the laser vertical and horizontal module to constantly indicate the center of the earth. Accordingly, the weight constantly indicates the center of the earth even if the user inclines the electrical drill. |
