Embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention, ties below
Closing drawings and examples, the present invention is further described.
Embodiment, as shown in Figure 1：A kind of electric hammer with shock-absorbing function, including electric hammer main body, wherein electric hammer main body include slow
Rush body 20 and rear hammer body 30；It is characterized in that：Wherein buffer body 20 is slidably connected with rear hammer body 30 by elastic positioning device,
Wherein elastic positioning device includes elastic device, and wherein elastic device includes locating slot 23, locating dowel 33 and elastic component at least
One；Wherein elastic device is three including locating slot 23, locating dowel 33 and elastic component and composition equilateral triangle is set；Wherein
Elastic device is four including locating slot 23, locating dowel 33 and elastic component and composition square is set；Wherein elastic device bag
It is five and composition regular pentagon setting to include locating slot 23, locating dowel 33 and elastic component；Preferably, elastic device includes positioning
Groove 23, locating dowel 33 and elastic component are four；Wherein locating slot 23, locating dowel 33 and elastic component, which correspond, is set；Wherein
Locating slot 23 is opened on buffer body 20, and wherein locating dowel 33 is located on rear hammer body 30, and wherein elastic component is spring 10, and it is hit by a bullet
One end of spring 10 is stretched into locating slot 23 and contradicted with bottom land, wherein the other end of spring 10 in locating dowel 33 and with rear hammer body 30
Contradict.Using said structure when electric hammer buffer body 30 is acted on by external force in the presence of elastic component slowly to close to rear hammer body
30 directions are slided, and are so effectively reduced electric hammer and are shaken caused by handle part and then reduce because vibrations are to user's hand at work
Injury and because vibrations reduction avoids electric hammer from high vibrating state extending its service life for a long time, when electric hammer is by delaying
When rushing the external force of body 20 to rear hammer body 30 and reducing, due to rebound effect buffer body 20 in the presence of the elastic component slowly to away from after
The direction of hammer body 30 is slided, and is so further reduced the influence to being arranged on motor in buffer body 20 and then is protected motor and energy
Alleviate and shake and then reduce because shaking the injury to user's hand caused by handle part.
As shown in Fig. 2 to Fig. 3：Wherein elastic positioning device also includes carriage, and wherein carriage is slow including being located at
The sliding shoe 21 rushed in body 30 and the slide rail 31 being located in rear hammer body 30, wherein its slide rail 31 are located in rear hammer body 30 including two
Raised item, wherein sliding shoe 21 is between two raised items, such sliding shoe 21 buffer body in 31 enterprising line slip of slide rail
20 slip route is limited, and preferably can play shock absorbing effect by assistant spring device.Wherein elastic positioning device also wraps
Positioner is included, wherein positioner includes the limited block being located at outside buffer body 20 and the spacing preiection for being located at rear hammer body 30, this
Kind limited block and spacing preiection, which cooperate, to be played a part of limiting the slip distance of buffer body 20, is avoided that elastic device rises and is buffered
Make during cushioning effect buffer body 20 slip away after hammer body 30.Wherein limited block includes main limited block 221 and time limited block 222, wherein
Spacing preiection includes main spacing preiection 321 and time spacing preiection 322, so not only acts as the effect of double limitation and can disperse
The power of the interphase interaction of limited block and spacing preiection and then slow down the abrasion between limited block and spacing preiection and extend it and use the longevity
Life.
As shown in Figure 4：Elastic protecting sleeve 40 wherein is arranged with outside spring 10, can not only further limit the position of spring 10
Put, it is more attractive in appearance and between further functioning as shake act on.Heat emission hole 25 is offered on buffer body 20, for motor radiating,
Avoiding motor, heat aggregation can not in time radiate and be burned out motor at work, extend its service life.On buffer body 20
Open up fluted 24 and be used for motor radiating, avoiding motor, heat aggregation can not in time radiate and be burned out motor at work, prolong
Its long service life.Hammer body 30 includes being bolted connected upper rear hammer body and lower rear hammer body after wherein, is so easy to delay
The handling rushed between body 20 and rear hammer body 30.
Electric hammer is widely used at present, and other structures and principle are same as the prior art, repeat no more here.
