Auxiliary device for preventing electric pick drill rod from falling off and removing dust

Abstract

The invention relates to the technical field of electric tools, and discloses an auxiliary device for preventing an electric pick drill rod from falling off and removing dust. The auxiliary device comprises a machine shell, a pressing rod is slidably connected to the left side of the machine shell, a first pushing block is slidably connected to the right side of the pressing rod, and a first stop block is arranged on the right side of the first pushing block; a first push rod is rotationally connected to the surface of the first stop block, a second push block is rotationally connected to the surface of the first push rod, and a first long rod is arranged on the right side of the second push block. According to the auxiliary device for preventing the electric pick drill rod from falling off and removing the dust, the first push rod drives the first stop block and the second push block to rotate, the first stop block drives the pressing rod to slide downwards by pressing the first push block, and the second push block drives a fixing rod to slide downwards by pressing the first long rod; when a movable contact is in contact with a fixed contact, an electrorheological fluid solution on the upper portion of the fixing rod becomes solid, and therefore the anti-falling effect is achieved by fixing the surface of a drill rod through the pressing rod, the first push rod and the fixing rod.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an auxiliary device for preventing falling off and removing dust of electric picks and drills. Background technique [0002] With the continuous development of social and economic conditions, electric picks have been widely used in the fields of mechanical installation, water supply and drainage facilities construction, and interior decoration. Electric picks are double-insulated hand-held electric tools powered by electric motors, which are safe, reliable and easy to operate. The convenient features are deeply liked and concerned by construction workers, thus promoting the research and development of electric pick equipment. [0003] At present, there are many types of electric picks on the market, and they generally lack anti-falling devices. When construction workers operate on the ground or walls, the drills may fall off or shake left and right under strong vibrations,...
