Abstract

The invention relates to an electric drill bit clamping device. The electric drill bit clamping device comprises an upper clamping block, a lower clamping block and a sleeve, wherein the upper clamping block and the lower clamping block are transversely zygomorphic half cylinders with rectangular notches formed in the circle centers; the two clamping blocks form a cylinder with a rectangular notch in the circle center; the outer sides of the upper clamping block and the lower clamping block are provided with threads connected together; the sleeve is a column with a bottom face; the bottom face is provided with a round hole allowing a drill bit to penetrate through; an inner thread is arranged inside the sleeve. The electric drill bit clamping device has the advantages that one end of the drill bit is made to be rectangular, the centers of the drill bit clamping blocks are provided with the rectangular notches matched with the drill bit, the drill bit and the clamping blocks are matched more tightly, and as sleeve locking is adopted, convenience and easiness are achieved.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric drill bit clamping device. Background technique [0002] The existing electric drill bits are cumbersome to install and operate, requiring the use of special installation tools, and the electric drill has a circular cross section, which is easy to cause slippage or fatigue damage when rotating at high speed.
