Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
as shown in accompanying drawing 1-3, a kind of reciprocator of reciprocating saw, it comprises main drive gear 1, auxiliary drive gear 2, reciprocating lever 3, resetting-mechanism 4.
the first gear 12 that main drive gear 1 comprises motor 11, driven by motor 11, concrete, the first gear 12 is connected with the output of motor 11.
the transmission that is meshed with the first gear 12 of the second gear 21.In order to reach the object that reduces rotating speed, the second gear 21 is gear wheel in the present invention, and the first gear 12 is pinion.If certainly put forward high-revolving object in order to reach, natural, the situation that the first gear 12 is pinion for gear wheel, the second gear 21 also should be included in protection scope of the present invention.
in the present invention, offer an irregular groove 25 in the outer rim of swiveling wheel 23, the dark minimum place 27, Shen Ziqi footpath, footpath of this groove 25 becomes large gradually, then is reduced gradually by the dark maximum 26 in its footpath.Groove 25 seamlessly transits to minimum place from maximum.
this reciprocator has two duties, and reciprocating lever 3 is in the time of retracted mode, and the restriction end 31 of reciprocating lever 3 is positioned at the dark maximum 26 in footpath, and reciprocating lever 3 is in the time stretching out state, and the restriction end 31 of reciprocating lever 3 is positioned at dark minimum place 27, footpath.
on swiveling wheel 23, offer a hole of passing for connecting pin 24, connecting pin 24 is fixedly connected by this connecting pin 24 with swiveling wheel 23.Connecting pin 24 turning cylinder around swiveling wheel 23 under the drive of swiveling wheel 23 rotates.
preferably, offer a circumferential groove (not marking in figure) on gear wheel, alignment pin is plugged in this circumferential groove, to ensure that alignment pin is more firm in motion process.
reciprocating lever 3 relatively swiveling wheel 23 slides along himself long axis direction.Reciprocating lever 3 has restriction end 31 and free end 32 on its long axis direction.The restriction end 31 of reciprocating lever 3 props up mutually with the groove 25 of swiveling wheel 23.Stretching out in process of reciprocating lever 3, it is 31 protruding that the restriction that the groove 25 of swiveling wheel 23 props up reciprocating lever 3 is held.On the free end 32 of reciprocating lever 3, be provided with saw cutter 6.On reciprocating lever 3, offer the reseting groove (not marking in figure) that a long axis direction along reciprocating lever 3 extends.
