Abstract
The utility model relates to an electric drill dustproof sleeve capable of preventing dust from splashing in operation, essentially comprising a sleeve body 1 as a non-cover cylinder; wherein the center of the cylinder bottom is provided with a hole, the wall of the sleeve body 1 is provided with regular folds 2, and a spiral spring 3 is embedded in the cylinder wall, therefore the sleeve body 1 can longitudinally telescope, two ends and the middle portion of the sleeve body 1 are respectively provided with a support 4, each support 4 is composed of two concentric metal rings of different sizes and support rods uniformly distributed between the two rings, the large metal ring is fixedly supported on the cylinder wall of the sleeve body 1, the small metal ring is arranged on the axis of thesleeve body, and the small metal ring is fixed on the large metal ring via the supports 4. After being sheathed on the drill rod of an electric drill, the electric drill dustproof sleeve can preventdust from splashing in operation and can collect dust, thereby effectively reducing environment pollution and protecting health of worker.
Description
Technical field
The utility model relates to a kind of protective jacket, especially a kind of electric drill dirt-proof boot.
Background technology
Usually will use electric drill when carrying out decoration construction, but traditional electric drill does not have dirt-proof boot, the dirt bits that produce when work can splash everywhere, and not only contaminated environment but also meeting directly influence the healthy of workmen.
The utility model content
The technical problems to be solved in the utility model is: a kind of electric drill dirt-proof boot that prevents that electric drill when construction dirt bits from splashing is provided.
For realizing above-mentioned technical problem, the utility model adopts following technical scheme:
This electric drill dirt-proof boot comprises the cover body, and cover is as the cylinder of a uncovered, and there is an aperture in the central authorities at the bottom of tube, is provided with embedding helical spring in the fold of rule and the barrel on the barrel of cover body, makes the cover body can longitudinal extension; Two ends and middle part at the cover body are provided with bracing frame, each bracing frame is made up of two concentric metal rings that vary in size and the support bar between two annulus, big metal ring is supported and fixed on the barrel of cover body, little becket is positioned on the axis of cover body, little becket is fixed on the big metal ring by bracing frame, and the little becket that is positioned at the bracing frame of cover body bottom overlaps with the aperture of tube end central authorities.
After adopting technique scheme, the beneficial effects of the utility model are:
After this electric drill dirt-proof boot is enclosed within on the drilling rod of electric drill, the splashing and can collect the dirt bits of dirt bits in the time of preventing to construct, the pollution that effectively alleviates environment, the protection constructor's is healthy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Accompanying drawing is the surface structure schematic diagram of an embodiment of this electric drill dirt-proof boot.
The specific embodiment
As shown in drawings: this electric drill dirt-proof boot mainly comprises cover body 1, and cover body 1 is the cylinder of a uncovered, and there is an aperture in the central authorities at the bottom of tube, is provided with embedding helical spring 3 in the fold 2 of rule and the barrel on the barrel of cover body 1, makes the cover body 1 can longitudinal extension; Two ends and middle part at cover body 1 are provided with bracing frame 4, each bracing frame 4 is made up of two concentric metal rings that vary in size and the support bar that is evenly distributed between two annulus, big metal ring is supported and fixed on the barrel of cover body 1, little becket is positioned on the axis of cover body 1, little becket is fixed on the big metal ring by bracing frame 4, and the little becket that is positioned at the bracing frame of cover body bottom overlaps with the aperture of tube end central authorities.
When using the electric drill construction, the small sircle hole of this electric drill dirt-proof boot bottom and the small circle ring of bracing frame are enclosed within on the drilling rod of electric drill, the position that will punch drill bit then, the dirt bits that then produce will be collected by this dirt-proof boot, and along with going deep into of drilling rod, dirt-proof boot can vertically be compressed to be close on the wall, can effectively prevent flying upward of dirt bits.
