Detachable drill bit with dust sucking function

Abstract

The invention provides a detachable drill bit with a dust sucking function. The detachable drill bit with the dust sucking function comprises a dust sucking drill bit, a fixed shaft sleeve, a dust collecting shaft, a shank piece and a thread hose; the dust collecting shaft is fixedly welded on the dust sucking drill bit; the shank piece is fixedly welded on the dust collecting shaft; a drilling end is fixedly mounted at the front end of the dust sucking drill bit; an attraction hole in a center shaft direction of the dust sucking drill bit is formed in the dust sucking drill bit; the dust collecting shaft is of a hollow cylinder structure, and is provided with a dust falling hole on the outer wall; the attraction hole communicates with the dust collecting shaft; the outer periphery of thedust collecting shaft is sleeved with the fixed shaft sleeve; a guide hole is formed in the bottom end of the fixed shaft sleeve; the guide hole is in threaded connection with a transfer pipe; and thetransfer pipe is in hoop connection with the thread hose. The detachable drill bit with the dust sucking function is simple in structure and convenient to install; six sets of crushing blocks are fixedly mounted in a front end inlet of the attraction hole; massive dust entering the attraction hole is crushed through the crushing blocks to prevent blockage of the attraction hole, so that the dustsucking efficiency is improved; and the fixed shaft sleeve and the dust collecting shaft are easy to disassemble to achieve the cleaning and maintenance convenience.

Description

Technical field [0001] The invention relates to the technical field of lighting lamps, in particular to a detachable drill bit with a dust collection function. Background technique [0002] Electric tools, electric hammers are a type of electric drill, mainly used to drill holes in concrete, floor slabs, brick walls and stone. Professional drilling on wall, concrete, stone, and multi-function electric hammer, adjust to the proper position with proper drill bit can replace ordinary electric drill, electric pick. The electric hammer is based on the electric drill, adding a piston with a crankshaft connecting rod driven by an electric motor, and reciprocating compressed air in a cylinder, so that the air pressure in the cylinder changes periodically, and the changing air pressure drives the hammer in the cylinder to reciprocate Hit the top of the drill bit. Because the drill bit of the electric hammer produces rapid reciprocating movement along the direction of the electric drill ...
