Problems solved by technology
However, there are still some defects in this bracket: after the percussion drill drills into the ceiling, the handle is pressed down to deform the parallelogram and cause the brace to rise, so that the drill bit gradually penetrates into the ceiling, but the parallelogram deformation not only causes the brace to rise, but also causes the brace to move left and right. Displacement, so the drilled hole is either oblique, or the impact drill is fixed to the drill and cannot be rotated

The invention relates to a portable and adjustable percussion drill support for ceiling drilling. The portable and adjustable percussion drill support for ceiling drilling comprises a base, a fixed supporting leg, universal wheels, a first stand column, a second stand column and a stabilizing and moving handle, wherein the fixed supporting leg and the universal wheels are fixed under the base, the first stand column and the second stand columns are fixed on the base, and the stabilizing and moving handle is fixedly connected with the first stand column and the second stand column and extends towards the fixed supporting leg. The first stand column is higher than the second stand column. The second stand column is a hollow pipe. A lower supporting rod is inserted in the hollow pipe. The lower supporting rod is hinged to a pressing rod. A roller is arranged at the upper end of the first stand column. The lower supporting rod is inserted in a middle supporting rod. An upper supporting rod is inserted in the middle supporting rod. The upper supporting rod, the middle supporting rod and the lower supporting rod are each provided with a plurality of through holes. Lock pins are inserted in the through holes. A percussion drill fixing base is fixedly arranged at the top end of the upper supporting rod. Compared with the prior art, the portable and adjustable percussion drill support for ceiling drilling is simple in structure and convenient to move, manual climbing operation is not needed, potential safety hazards are eliminated, working efficiency is improved, and the phenomena of forming oblique holes and getting stuck are avoided as the supporting rods are kept perpendicular to a ceiling all the time.
Description
technical field [0001] The invention relates to the technical field of electric tool accessories, in particular to a portable ceiling opening adjustable percussion drill bracket. Background technique [0002] At present, it is very difficult to drill holes in ceilings with a high height from the ground. Manual climbing is required, and operators need to raise their heads to operate. Dust is more harmful to the respiratory tract, and applying force upwards requires first overcoming the weight of the percussion drill itself. And the human body can't be used to lift the head and lean back, so punching a hole is time-consuming, labor-intensive, inefficient and has potential safety hazards. [0003] The Chinese invention patent with the publication number CN103273116A discloses a percussion drill bracket, which is characterized in that: the percussion drill is placed on the electric drill seat fixed on the mandrel and is fastened by at least two straps, the mandrel of the mandrel...
