Holding-free electric hand drill

Abstract

The invention discloses a holding-free electric hand drill. The holding-free electric hand drill comprises a sliding part, an angle adjusting device and a fixing suction cup, wherein the sliding part comprises a hand screw, a dovetail groove transverse connecting piece, dovetail grooves, a motor and a spherical joint; left and right sides of the motor are connected with dovetail sliders matched with the dovetail grooves, and the lower side of the motor is connected with a drill bit or grinding wheel; a rhombic hole is formed in the middle of the dovetail groove transverse connecting piece, a movable fixing nut is arranged in the hole, the external thread of the hand screw is matched with the movable nut, and the hand screw rotationally penetrates the nut and is connected to the spherical joint at the top end of the motor; the angle adjusting device comprises a movable fixing structure arranged on one sides of the bottom ends of the dovetail grooves and an angle adjusting structure arranged on the other sides. The holding-free electric hand drill has the following advantages: 1, the holding-free electric hand drill is convenient and flexible, is suitable for various working conditions and drill holes precisely; 2, the holding-free electric hand drill is widely applied and can be applied to a condition under which a bench drill cannot be used; 3, the holding-free electric hand drill is free of holding and can perform drilling without hand holding; 4, the holding-free electric hand drill can drill oblique holes at fixed angles.

Description

technical field [0001] The invention relates to the field of electric drills, in particular to a hands-free electric drill. Background technique [0002] During production, some workpieces cannot be moved to the bench drill for drilling, and because the bench drill is large in size and inconvenient to move, the bench drill cannot be moved to the tool to drill holes; when using a hand-held electric drill to drill holes, the hand-held electric drill is not easy to control and operate. There will be various problems in the holes made by insufficient masters, and it is difficult for even skilled masters to master them. Contents of the invention [0003] The object of the present invention is to provide a hand-free electric drill which is easy to control and operate, and can drill fixed-angle inclined holes. [0004] The hands-free electric drill of the present invention includes a sliding part, an angle adjustment device and a fixed suction cup; [0005] The sliding part inc...
