The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to restriction of the present utility model.
Such as Fig. 1～shown in Figure 3, the dust gathering arrester of the first embodiment of the present utility model comprises: a hollow sleeve 10, this sleeve 10 is made with plastic material, can engage with the stiff end 20 of an electric hand-held tool 2, these stiff end 20 the place aheads have the moved end of work 21, do can engage with a drill bit 22 before the moved end 21.Sleeve 10 front side outer walls have external screw thread 11, and stiff end 20 outer rims of corresponding electric hand-held tool 2 have a holding section 12 in the inwall projection, stiff end 20 clampings of holding section 12 and electric hand-held tool 2; And a cover body 13, be clear hollow, inboard and hollow sleeve 10 combinations of an end, internal diameter pulls out shape by being gradually to push away greatly to another opposite end in conjunction with hollow sleeve 10 ends, cover body 13 walls are the fold shape, have elasticity, one unclasp and have the function that automatically replies after compressed.Cover body 13 has internal thread 14 in conjunction with hollow sleeve 10 end inwalls, and internal thread 14 screws togather with the external screw thread 11 of sleeve 10.The outboard end leading edge of cover body 13 bore maximums is extended with the section 15 that reclines toward inner bending, cover body 13 bosoms have an isolation part 16 that is oblique shape (＜shape), direction is tiltedly stretched towards the outboard end of cover body 13 bore maximums in isolation part 16, the center has a through hole 17, and through hole 17 passes for the drill bit 22 of electric hand instrument 2;
Such as Fig. 3～shown in Figure 5, the internal thread 14 of dust gathering arrester 13 screws togather fixing with the external screw thread 11 of sleeve 10.During use, make the holding section 12 of sleeve 10 and stiff end 20 clampings of electric hand-held tool 2, with stiff end 20 combinations of cover body 13 with electric hand-held tool 2, make the section that the reclines 15 applying metopes 3 of cover body 13, again electric hand-held tool 2 is pushed away to metope 3, make cover body 13 compressions, make the drill bit 22 of electric hand-held tool 2 against metope, can begin metope 3 borings, cover body 13 observable drill bits 22 start situations, and the dust that when boring produces becomes scattered about in the cover body 13, and separated by isolation part 16 to stop.Because the drill bit 22 of electric hand-held tool 2 stretches out outside the through hole 17 of cover body 13 isolation parts 16, moved end 21 isolation are done with dust and electric hand-held tool 2 in isolation part 16 that can be by cover body 13, that avoids that dust enters electric hand-held tool 2 does moved end 21, can prolong the service life of electric hand-held tool 2; Dust gathering arrester has flexible, and the drill bit 22 of electric hand-held tool 2 can be holed with different angles.
As shown in Figure 6 and Figure 7, the second embodiment of the present utility model and the first embodiment difference are, the wall of this cover body 13 is not established fold, the cover body 13 that this outer wall is not established fold arranges a spring 4 in inside, and cover body 13 inwalls are erected on the spring 4 fixing, cover body 13 compressed rear one is unclasped, have the function that automatically replies.Its occupation mode and function are identical with the first embodiment.
