Abstract
The present invention discloses a high voltage insulating electric tool, comprising insulating handles made of plastic material, and insulating fittings made of ceramic material. The insulating fittings are mounted on the insulating handles in a replaceable manner to directly contact a work piece under service condition and prevent electric shock. The present invention adopts handles made of plastic material and cutting edges made of ceramic so that the entire product cannot bear a risk of breakdown by current in an environment of high voltage. The ceramic cutting edges made of ceramic are replaceable, thereby avoiding the circumstance that the entire metallic electric tool has to be scrapped due to burst, blunting or large clearance of the cutting edges. Further, plastic material and ceramic have desirable chemical stability and strong resistance to acids, alkalis and other chemicals.
