Abstract
The invention discloses an electric tool and particularly relates to a shoulder pad type electric hammer. The shoulder pad type electric hammer is composed of a shell, an internal slide rail, an internal elastic device, an internal pull rod, a protection layer, a back cushion and the like. The shoulder pad type electric hammer has the advantages that a novel structure is adopted, the electric hammer can exert force well when working is conducted on a wall surface or on a roof surface, and the problem that an electric hammer can not exert force well when working is conducted on the wall surface or on the roof surface is effectively solved; due to the fact that the electric hammer is in the type of a shoulder pad, the pull rod can be pulled out to a proper position and fixed through a buckle, a shoulder abuts against the back cushion, as a result, both the shoulder and hands can exert force at the same time, and working efficiency is improved.
Description
technical field:
the present invention relates to field of power tools, be 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 by motor, has been driven the piston that has crankshaft-link rod, reciprocating air in a cylinder, 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 when rotating, so it can punching fast on the materials such as the large cement concrete of fragility and stone material.
existing electric hammer structure is comprised 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 when working; only have handle part to exert oneself; so just caused when metope and shed top surface work and can not well have an effect, to work, caused inconvenience.
summary of the invention:
the object of the present invention is achieved like this: a kind of shoulder pad formula electric hammer; comprise housing, inner slideway, internal resilient means, inner pull bar, protective layer, back cushion etc.; it is characterized in that: housing top inner side is provided with an independently space; interior volume is provided with inner slideway; in inner slideway, have one to carve mutually with it the tensile inner pull bar closing, 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 a plurality of buckles, and buckle is the little cuboid of rule; Inner pull bar outside is provided with protective layer.
described back cushion position is that inner pull bar is connected with the center of back cushion, and protective layer is connected with back cushion.
the invention has the advantages that: use a kind of new structure, it can well have an effect when metope and shed top surface work, effectively solved when 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.
accompanying drawing explanation:
fig. 1 is the plane of shoulder pad formula electric hammer;
fig. 2 is the structure chart in cover top portion separate space.
the specific embodiment:
a shoulder pad formula electric hammer, comprises housing 1, inner slideway 2, inner pull bar 3, protective layer 4, back cushion 5, internal resilient means 6 etc.; Be characterised in that: casing top inner side is provided with an independently space, and interior volume is provided with inner slideway 2, in inner slideway 2 inside, has one to carve mutually with it the tensile inner pull bar 3 closing, and the outer end of inner pull bar 3 is connected with back cushion 5.
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.
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.
described inner pull bar 3 can rotate in inner slideway 2 inside, and inner pull bar 3 is provided with a plurality of buckles, and buckle is the little cuboid of rule; Inner pull bar 3 outsides are provided with protective layer 4.
5 described of back cushions are that inner pull bar 3 is connected with the center of back cushion 5, and protective layer 4 is connected with back cushion 5.
Claims (5)
1. a shoulder pad formula electric hammer; comprise housing, inner slideway, internal resilient means, inner pull bar, protective layer, back cushion etc.; it is characterized in that: housing top inner side is provided with an independently space; interior volume is provided with inner slideway; in inner slideway, have one to carve mutually with it the tensile inner pull bar closing, the outer end of inner pull bar is connected with back cushion.
2. a kind of shoulder pad formula electric hammer according to claim 1, is characterized in that: inner slideway is the solid of a hollow out, and outside is close to housing inner side.
