Abstract
The utility model discloses an electric tool, particularly a shoulder pad type electric hammer. The electric hammer consists of a casing, an internal slipway, an internal elastic device, an internal pull rod, a protective layer and a cushion. 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 increase the working efficiency.
Description
technical field:
the utility model relates to field of power tools, is specifically related to a kind of structure of shoulder pad formula electric hammer.
background technology:
in prior art, in electricity consumption class instrument, electric hammer is the class in electric drill, be mainly used to hole on concrete, floor, brick wall and stone material, electric hammer is on the basis of electric drill, has increased by one and has been driven the piston that has crankshaft-link rod, reciprocating air in a cylinder by motor, make cylinder inner air pressure be the cycle and change, 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.
existing electric hammer structure is made up of housing, 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; comprise housing, inner slideway, inner pull bar, protective layer, back cushion, internal resilient means; be characterised in that: housing top inner side is provided with an independently space; 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 inner slideway is the solid of a hollow out, and outside is close to housing inner side topmost, and inner slideway inner side is provided with inner pull bar.
described internal resilient means is to be looped around on inner pull bar, and one end and housing are fixed, and the other end and inner pull bar are fixed.
described inner pull bar can rotate in inner slideway inside, and inner pull bar is provided with multiple buckles, and buckle is the little cuboid of rule, 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, and adopts shoulder pad formula, pull bar can be pulled out to applicable position, pull bar fixed by snap, shoulder is withstood on back cushion, shoulder and hand are had an effect simultaneously, increase work efficiency.
brief description of the drawings:
fig. 1 is the plane of shoulder pad formula electric hammer;
fig. 2 is the structure chart in cover top portion separate space.
detailed description of the invention:
embodiment 1
a kind of shoulder pad formula electric hammer; comprise housing 1, inner slideway 2, inner pull bar 3, protective layer 4, back cushion 5, internal resilient means 6; be characterised in that: housing top inner side is provided with an independently space; interior volume is provided with inner slideway 2; have one to carve mutually with it the tensile inner pull bar 3 closing in inner slideway 2 inside, the outer end of inner pull bar 3 is connected with back cushion 5.
embodiment 2
described inner slideway 2 is solids of a hollow out, and outside is close to housing inner side topmost, and inner slideway 2 inner sides are provided with inner pull bar 3.
embodiment 3
described internal resilient means 6 is to be looped around on inner pull bar 3, and one end and housing 1 are fixing, and the other end and inner pull bar 3 are fixing.
embodiment 4
described inner pull bar 3 can rotate in inner slideway 2 inside, and inner pull bar 3 is provided with multiple buckles, and buckle is the little cuboid of rule, and inner pull bar 3 outsides are provided with protective layer 4.
embodiment 5
described inside pull bar 3 is connected with the center of back cushion 5, and protective layer 4 is connected with back cushion 5.
Claims (5)
