Problems solved by technology
The face of the construction personnel is relatively close to the hole, and the eyes are easily fascinated by the drilled ash; when drilling different installation holes, it is necessary to frequently move up and down and move the ladder or scaffolding, which is time-consuming and labor-intensive, and the construction efficiency is slow
When constructing a factory building or a shopping mall with a high floor, etc., the working position is high, which is easy to cause danger and cause work-related injuries

The invention discloses an impact drill support, and relates to building decoration, water, electricity and heating construction tools. The impact drill support comprises a base, a fixed strut and a movable strut. The lower end of the fixed strut is fixedly connected with the base, at least two hinge holes are respectively longitudinally and equidistantly formed in each of the fixed strut and the movable strut, a driving swing arm is hinged into one hinge hole of the fixed strut by a bolt, the middle of the driving swing arm is hinged to the fixed strut, the front of the driving swing arm is hinged to the movable strut by a bolt, and a control handle is arranged at the rear of the driving swing arm; each stable swing arm which is parallel to the driving swing arm is arranged on a corresponding side of the driving swing arm, and two ends of each stable swing arm are respectively hinged to the corresponding hinge holes in the fixed strut and the movable strut by bolts; an impact drill fixing seat and a power socket are arranged on the upper portion of the movable strut, a power cord is connected onto the power socket, and a control switch is arranged on the power cord. The impact drill support has the advantages that the top of a building can be drilled by the impact drill support on the ground without the aid of ladders or scaffolds, and the impact drill support can be used easily and conveniently, is high in construction efficiency and is risk-free.
Description
technical field [0001] The invention relates to a construction tool for building decoration and water, electricity and heating, in detail, it is a percussion drill bracket which is simple and convenient to use, high in construction efficiency and non-dangerous. Background technique [0002] We know that in building decoration or interior decoration, it is often necessary to use a percussion drill to drill installation holes on the top of the building layer, and install expansion bolts in the installation holes to fix ceilings, air conditioners and other items that need to be installed. At present, the process of drilling installation holes on the top of the building (such as the roof) is: first, the construction personnel erects the ladder or scaffolding below the installation hole to be punched, the portable impact drill boards the ladder or scaffolding, and the building is placed on the ladder or scaffolding. Drill the top. The face of the construction workers is relative...
