Abstract

The invention discloses a polygonal punching tool. The polygonal punching tool comprises a drill bit assembly and a cutting assembly. The drill bit assembly comprises a driving element and a spiral drill bit; the spiral drill bit is fixedly connected to the output end of the driving element; the cutting assembly comprises cutting side plates, the multiple cutting side plates are bent with the radian A to be enclosed and spliced to form a polygon, and the polygon sleeves the drill bit assembly; discharging holes are formed in the cutting side plates; and cutting corners are arranged at the bottom ends of the cutting side plates. Soil around a round hole can be cut in a polygonal mode when the spiral drill bit performs punching, the cut soil is brought out through rotation of the spiral drill bit, and the operation efficiency is improved; and meanwhile, punching operation of various polygonal holes is achieved through the bending frequency change of the cutting tool.

Description

technical field [0001] The invention relates to the technical field of cutting, in particular to a polygonal drilling tool. Background technique [0002] Electric power engineering construction vehicles have become an important tool for the construction and maintenance of electric power equipment, and have played an active role in improving construction efficiency and reducing personnel workload and labor intensity. Since the bottom of the utility pole often needs to be reinforced with a rectangular cornerstone, the current drilling of rectangular utility poles mainly uses manual excavation or auger drills to drill circular holes, and then manually corrects them. The work efficiency is low and the labor intensity is high. The work period is long. Contents of the invention [0003] The purpose of the present invention is to provide a polygonal drilling tool for solving at least one of the above technical problems, which can realize direct drilling of holes in rectangular u...
