Described sheath 5 is stainless steel sheath, corrosion-resistant, long service life.
Described dustproof cover body 6 front ends arrange cushion collar 10, have damping effect, protect dustproof cover body 6 wear preventions, and are more conducive to the laminating of dustproof cover body 6 and body of wall and ceiling.
Described cushion collar 10 is rubber cushion cover, good damping effect, and long service life, cost is low.
Described dustproof cover body 6 is connected with slide block 8 by screw 11, replacing slide block 8 for convenience detach.
Described dustproof cover body 6 is for the dustproof cover body of stainless steel, corrosion-resistant, long service life.
Operation principle of the present utility model: the front end of electric hammer body is drill chuck, drill bit is installed on drill chuck, drill chuck arranged outside has thread head, sheath one end is connected with electric hammer body by thread head, facilitate spinning to use, sheath inner sleeve has dustproof cover body, jacket inner wall is offered annular groove, the slide block that the middle part outer wall setting of dustproof cover body matches with annular groove, described dust cover physical efficiency is slided in sheath, between sheath and dustproof cover body, Compress Spring is set, Compress Spring is pressed between sheath and dustproof cover body, Compress Spring one end is connected with sheath, the Compress Spring other end is connected with slide block, during use, dustproof cover body can rely on Compress Spring flexible, and dustproof cover body can be close to body of wall together along with drill bit, when drill bit creeps into body of wall, dustproof cover body is along with progress is to after-contraction, and dustproof cover body is close to all the time body of wall and is used, after boring finishes, the unified dust rubbish of pouring out collection.
The beneficial effects of the utility model are: 1, be applicable to the more shallow hole of drilling depth, while using electric hammer, dustproof cover body can rely on Compress Spring flexible, dustproof cover body and drill bit almost touch body of wall or ceiling simultaneously, boring dust on body of wall or ceiling and chip just fall in dustproof cover body and are not scattered everywhere, bored behind hole, the dust in dustproof cover body runs up to a certain degree, will unload lower jacket cleaning.2, sheath and dustproof cover body are all selected stainless steel, corrosion-resistant, long service life.3, dustproof cover body front end arranges rubber cushion cover, the dustproof cover body wear prevention of protection, and there is good damping effect.4, rubber cushion cover has elasticity, is more conducive to the laminating of dustproof cover body and body of wall and ceiling.
