Technical Field

The invention belongs to the technical field of machining, and particularly relates to an angular electric hand drill drilling positioning and fixing tool.

Background

At present, more electric hand drills are adopted as direct-entering electric hand drills, the directions of machine bodies and drill chucks of the electric hand drills are consistent, and the electric hand drills are easy to drill, position and fix. However, when space is limited, an electric hand drill with a drill chuck and a body forming an angle of 90 ° may also be used. The angular electric hand drill has a complex structure and limited positioning space, so that the positioning difficulty is increased. The angular electric hand drill is not convenient to rotate like a straight-in electric hand drill, and the problem of interference of a machine body needs to be considered. Therefore, the fixing mode of the angular electric hand drill needs to be flexibly applied by combining the characteristics of the machine body.
