Abstract
The utility model discloses an electric tool, particularly a shoulder pad dustproof electric hammer. The electric hammer consists of a casing, a drill chuck, a dustproof cover, a clamping groove, an internal slipway, an internal pull rod, a protective layer, a cushion and an internal elastic device. The electric hammer has the advantages that through the adoption of a novel structure, the electric hammer can power better on the wall surface and a ceiling, so that the problem that the electric hammer is adverse to power generation when the electric hammer is used for operating the wall surface or the ceiling, is effectively solved. Through the adoption of the shoulder pad type, the pull rod can be pulled to a suitable position and is fixed through a buckle, so that the shoulders and the hands can power at the same time to improve the working efficiency; at the same time, the dustproof cover fixed on the drill chuck can be used for collecting dust, so as to reduce the spreading of dust, weaken the harm to human bodies, and protect environment.
Description
technical field:
the utility model relates to field of power tools, is specifically related to the structure of the dustproof electric hammer of a kind of shoulder pad formula.
background technology:
in prior art, in electricity consumption class instrument, electric hammer is the class in electric drill, the electric hammer that is mainly used to hole on concrete, floor, brick wall and stone material is on the basis of electric drill, increase by one and driven the piston that has crankshaft-link rod by motor, reciprocating air in a cylinder, make cylinder inner air pressure be the cycle and change, and the air pressure of variation drives the hammer in cylinder back and forth to hit the top of drill bit and carries out work.Because the drill bit of electric hammer has also produced along the fast reciprocating frequent impact of the direction of electric drill bar in rotating, so it can punching fast on the large material such as cement concrete and stone material of fragility.Due to when in metope and ceiling work, a large amount of dusts that drop, very easily suck human lung, suck for a long time dust, easily make people suffer from occupational disease, and physical and mental health is damaged, and the dust simultaneously dropping is also unfavorable for sweeping, environment is also exerted a certain influence,
existing electric hammer structure is made up of housing, drill bit, drill chuck, roller, transmission system, power line etc.Wherein, transmission system comprises that electricity turns device of air, impact piston, hammer body, mechanical type overload protection arrangement and each change-speed gearing; because electric hammer is in the time working; only have handle part to exert oneself; so just cause in the time of metope and shed top surface work and can not well have an effect, caused inconvenience to work.
utility model content:
the purpose of this utility model is achieved in that a kind of shoulder pad formula electric hammer that prevents dust, and comprises housing, drill jig, dust cover, draw-in groove, inner slideway, inner pull bar, protective layer, back cushion, internal resilient means; Be characterised in that at drill chuck afterbody and be provided with draw-in groove, on draw-in groove, have fixture, housing top inner side is provided with an independently space, and interior volume is provided with inner slideway, have one to carve mutually with it the tensile inner pull bar closing in inner slideway inside, the outer end of inner pull bar is connected with back cushion.
described dust cover is dismountable, and dust cover is rotated a circle around drill jig, cylindrical, is stuck in draw-in groove, is fixed by fixture.
described inner slideway is the solid of a hollow out, and outside is close to housing top inner side.
described elastic device is looped around on inner pull bar, and one end and housing are fixed, and the other end and inner pull bar are fixed.
described inside pull bar can rotate in inner slideway inside, and inner pull bar is provided with multiple buckles, and inner pull bar outside is provided with protective layer.
described inside pull bar is connected with the center of back cushion, and protective layer is connected with back cushion.
the utility model has the advantage of: use a kind of new structure; it can well have an effect in the time of metope and shed top surface work; effectively solve in the time of metope or ceiling work; electric hammer is unfavorable for the problem of having an effect; adopt shoulder pad formula; pull bar can be pulled out to applicable position; pull bar fixed by snap, withstands on back cushion shoulder, and shoulder and hand are had an effect simultaneously; increase work efficiency; meanwhile, the dust cover that is fixed on drill chuck can be collected dust, has reduced the diffusion of dust; weaken the harm to health, protected environment.
brief description of the drawings:
fig. 1 is a kind of plane of dustproof shoulder pad formula electric hammer.
fig. 2 is the structure chart in cover top portion separate space.
detailed description of the invention:

the dustproof electric hammer of a kind of shoulder pad formula; comprise housing 1, drill jig 2, dust cover 3, draw-in groove 4, inner slideway 5, inner pull bar 6, protective layer 7, back cushion 8, internal resilient means 9; it is characterized in that: the top inner side of housing 1 is provided with an independently space; interior volume is provided with inner slideway 5; have one to carve mutually with it the tensile inner pull bar 6 closing in inner slideway 5 inside, the outer end of inner pull bar 6 is connected with back cushion 8.
embodiment 2
described dust cover 3 is dismountable, and dust cover 3 is rotated a circle around drill jig 2, cylindrical, is stuck in draw-in groove 4, fixed by fixture,
embodiment 3
described inner slideway 5 is solids of a hollow out, and outside is close to housing 1 top inner side.
embodiment 4
described elastic device 9 is looped around on inner pull bar 6, and one end and housing 1 are fixing, and the other end and inner pull bar 6 are fixing.
embodiment 5
described inner pull bar 6 can rotate in inner slideway 5 inside, and inner pull bar 6 is provided with multiple buckles, and inner pull bar 6 outsides are provided with protective layer 7.
embodiment 6:
described inside pull bar 6 is connected with the center of back cushion 8, and protective layer 7 is connected with back cushion 8.
