The specific embodiment
For clearer expression goal of the invention of the present utility model and advantage, be described in detail below in conjunction with accompanying drawing and the utility model one preferred embodiment.
As shown in Figure 2, a kind of reciprocating saw comprises: casing 01, drive unit 02 and transmission device 05.Drive unit 02 is arranged in the casing 01, and transmission device 05 is connected in drive unit 02 by gear train 03, and gear train 03 is engaged in drive unit 02.Transmission device 05 comprises: pendulous device 04 and reciprocating lever 07.Pendulous device 04 is connected in gear train 03, and gear train 03 can be converted to drive unit 02 rotating speed the rotating speed in pendulous device 04 working range by a certain percentage.Pendulous device 04 is provided with swing arm 10, and swing arm 10 slidably is connected in reciprocating lever 07, and reciprocating lever 07 moves reciprocatingly under the driving of swing arm 10.The outer guide pin bushing 06 that is arranged with of reciprocating lever 07, guide pin bushing 06 is fixed in the casing 01, and it is reciprocating in an ideal way that guide pin bushing 06 can effectively limit reciprocating lever 07.In conjunction with shown in Figure 3, guide pin bushing 06 is provided with slotted eye 09, and slotted eye 09 can make the swing arm 10 on the pendulous device 04 pass and drive reciprocating lever 07, thereby avoids the collision of guide pin bushing 06 and swing arm 10.Guide pin bushing 06 has chute 08, and structure is corresponding therewith, and an end of reciprocating lever 07 is provided with slide block 11, and slide block 11 can slide along chute 08, thereby has limited rotation and the swing of reciprocating lever 07.
The guide pin bushing 06 removable independent case that is divided into two same structures, because the independent case of two same structures is fixed in the casing 01 of a reciprocating saw, thereby the splicing of two independent case is without any need for techniques such as welding, be easy to assembling, and can not affect the usefulness that 06 pair of reciprocating lever of whole guide pin bushing 07 moves back and forth restriction.To describe present embodiment in order better knowing, shown in Fig. 4,5 and 6, because the structure of two independent case is identical, only to have represented the structure of an independent case among the figure.The Y-axis of coordinate system is described first direction among the figure, and the Z axis of coordinate system is described second direction among the figure, and the X-axis of coordinate system is described third direction among the figure.Guide pin bushing 06 is the tube-like piece that extends along described first direction (Y-axis); Guide pin bushing 06 has roof, diapire and is connected in the pair of sidewalls of described roof and diapire, and the roof of guide pin bushing 06 and diapire are oppositely arranged along the second direction (Z axis) perpendicular to first direction (Y-axis); The pair of sidewalls of guide pin bushing 06 is along being oppositely arranged perpendicular to the third direction (X-axis) of first direction (Y-axis) with second direction (Z axis).As shown in Figure 4, guide pin bushing 06 is the symmetrical independent case that is split as two same structures on the plane of first direction and second direction restriction, and namely two independent case are spliced into guide pin bushing 06 in Y-Z plane symmetry mode.Such connecting method is so that chute 08 complete the remaining on the guide pin bushing 06, thereby guaranteed the firm of chute 08; As shown in Figure 5, guide pin bushing 06 is the symmetrical independent case that is split as two same structures on the plane of first direction and third direction restriction, namely two independent case are spliced into guide pin bushing 06 along the X-Y plane symmetric mode, and such connecting method has guaranteed the complete of slotted eye 09; As shown in Figure 6, guide pin bushing 06 is the symmetrical independent case that is split as two same structures on the plane of second direction and third direction restriction, and namely two independent case are spliced into guide pin bushing 06 along X-Z plane symmetry mode.Further, compared with prior art, in industrial production was made, independent case not only can be made by the mode of die casting, but also can adopt the mode of direct metal plate punching press to make.Simultaneously, can also adopt the mode of casting and machined combination to make.Thereby simplify manufacturing and the processing of guide pin bushing 06, and saved material, reduced manufacturing cost.And can make guide pin bushing 06 in industrial medium quantity batch processing and manufacturing.Understandable, guide pin bushing 06 is not limited to the independent case that only is split as two same structures, can also be spliced by plural independent case.The concrete composition structure of guide pin bushing 06 is decided by the manufacturing and actual demand.
Above-mentioned is the utility model one preferred embodiment, but the utility model is not to be defined in this.Those skilled in the art within not breaking away from claim scope of the present utility model, all can do change and modification, and therefore protection domain of the present utility model is as the criterion with the claim limited range.
