The enclosure interior structure in housing 1 internal fixation a middle cover 14 is set, and this middle cover 14 has two support arms that protract 140 with reference to shown in Figure 2.Motor 11 rotations that cover in being fixed on drive an armature shaft 18.With armature shaft 18 separated by a distance, the main shafts 16 that be arranged in parallel, this main shaft 16 is fixed on the middle cover 14.Have a gear wheel 15 to be socketed on the main shaft 16, described gear wheel 15 can rotate around main shaft 16, and the engagement of the tooth of its periphery and armature shaft 18.The same with prior art, off-centre is provided with a driving shaft 17 on gear wheel 15, and this driving shaft 17 extend in the chute 26 with reciprocating lever 12 axial restraints.Chute 26 also adopts prior art, is one to have the bending plate of elongated slot and through hole, specifically can be with reference to Fig. 6, so repeat no more.
As shown in Figure 2, after motor 11 drove armature shaft 18 rotations, armature shaft 18 can drive gear wheel 15 around main shaft 16 rotations.The driving shaft 17 that is positioned on the gear wheel 15 just can change into chute 26 to rotatablely moving of self along the reciprocating motion on the X-axis line direction, and promptly reciprocating lever 12 and saw blade 13 move reciprocatingly along A direction among the figure.At this moment, X-axis line direction is parallel with the A direction.
The saw blade 13 of jigsaw 10 also has two kinds of mode of operations except doing along the reciprocating motion of A direction, in first mode of operation, saw blade 13 can rotate around axis X with respect to housing 1; In second mode of operation, saw blade 13 is made reciprocally swinging in its plane, place.
In first mode of operation, saw blade 13 is driven by the rotary drive mechanism 2 of jigsaw 10, produces rotatablely moving around the B direction of X-axis.As shown in Figure 2, described rotary drive mechanism 2 comprises a rotary handle 21, and the sleeve pipe 22 that can be rotated the handle drives rotation.Can see that in conjunction with Fig. 1 the holding end of this rotary handle 21 is arranged on the outside of housing 1, promptly can the person of being operated manually rotate.Rotary handle 21 is connected with an adapter sleeve 23 in the pin-and-hole mode, makes this adapter sleeve 23 and rotary handle 21 radially fixing.The other end of adapter sleeve 23 is connected with sleeve pipe 22, and these sleeve pipe 22 diameters are more bigger than reciprocating lever 12, are enclosed within reciprocating lever 12 outsides.In conjunction with shown in Figure 4, be symmetrically arranged with recess 223 on the wall of sleeve pipe 22, adapter sleeve 23 relevant positions are provided with projection 231, and projection 231 can be inserted into and make sleeve pipe 22 and adapter sleeve 23 also radially fixing in the recess 223.Like this, when rotary handle 21 when rotated, can drive sleeve pipe 22 and adapter sleeve 23 and rotate together.
As shown in Figure 5 and Figure 6, be symmetrical arranged two elongated slots 221 on the wall of described sleeve pipe 22; Correspondence is provided with two through holes 121 on the wall of described reciprocating lever 12, and each fixes a pin 122 in two through holes 121.Because the length of pin 122 is greater than the diameter of sleeve pipe 22, the elongated slot 221 of sleeve pipe is all passed at the two ends of two pins 122.Chute 26 is socketed on the sleeve pipe 22, and is arranged between two pins 122.Because pin 122 is fixed on the reciprocating lever 12, and two pins 122 all are against the both sides of chute 26, then between chute 26 and the reciprocating lever 12 with regard to axial restraint.Again since the two ends of pin 122 pass the elongated slot 221 of sleeve pipe 22 and can in elongated slot 221, slide, so chute 26 and reciprocating lever 12 can move axially along X-axis together with respect to sleeve pipe 22.
With reference to Fig. 2 and shown in Figure 6, when the saw blade 13 of jigsaw 10 when doing A direction reciprocating, promptly reciprocating lever 12 produces when moving back and forth, this moment, sleeve pipe 22 was with respect to the X-axis axial restraint.And when rotary handle 21 drove sleeve pipe 22 rotations, 221 pairs of pins of the elongated slot of sleeve pipe 22 122 produced driving force, made pin 122 and reciprocating lever 12 also can produce rotatablely moving of B direction around X-axis, can drive saw blade 13 and also produce rotatablely moving of B direction around X-axis.Because all radially unfixing between chute 26 and sleeve pipe 22 or the reciprocating lever 12, so when sleeve pipe 22 and reciprocating lever 12 rotations, chute 26 is radially fixing all the time, makes driving shaft 17 also can be inserted into chute 26 inside all the time.For sleeve pipe 22 and reciprocating lever 12 can be rotated with respect to chute 26 more swimmingly, present embodiment adds a chute bearing 27 between sleeve pipe 22 and chute 26.
So,, operate rotary handle 21 and can make saw blade 13 produce rotatablely moving around X-axis when motor-driven saw blade 13 produced along the reciprocating while of X-axis.
As shown in Figure 2, this preferred embodiment also is provided with cutter lifting driving mechanism 4.Described cutter lifting driving mechanism 4 comprises that pivot is fixed on the cutter lifting plate 41 of housing 1 inside, and by the push rod 42 and the wheel bracket 43 of 41 drivings of cutter lifting plate.The concrete structure of described cutter lifting plate 41 please refer to Fig. 7 and Fig. 8, and cutter lifting plate 41 has a matrix 411 that has an endoporus 414, and this endoporus can allow sleeve pipe 22 and reciprocating lever 12 pass.One end of matrix 411 is circular-arc, is in order to be complementary with housing 1 better.Be provided with in circular-arc end one with the perpendicular riser 412 of matrix 411.On matrix 411,, be provided with two relatively and the pedestal 413 vertical with matrix 411 with the riser 412 corresponding other ends.Respectively be provided with a pivot hole 415 on two relative pedestals 413, make cutter lifting plate 41 be fixed on housing 1 inside, and can rotate around pivot hole 415 by pivot.
Can see among Fig. 2 that what contact with riser 412 is gear wheel 15, the front end face of this gear wheel 15 is cam surfaces 151.When gear wheel 15 was driven rotation by motor 11, cam surface 151 can drive cutter lifting plate 41 and rotate around pivot hole 415.And the matrix 411 of cutter lifting plate 41 is propped up by push rod 42 all the time, and the other end of push rod 42 props up the wheel bracket 43 that has guide wheel 44 again.Guide wheel 44 adopts prior art, contacts with saw blade 13, can provide a support force all the time to saw blade 13.Wherein push rod 42 and wheel bracket 43 are arranged on the above-mentioned driving mechanism joint portion 6.In the present embodiment, the driving mechanism joint portion is a swivel mount 6, and this swivel mount 6 is socketed in the outside of sleeve pipe 22, can be with sleeve pipe 22 rotations.The bottom of swivel mount 6 is stretched out an arm downwards, has a hole 61 on arm, and described push rod 42 just is placed in this hole 61; And be pivotally connected to wheel bracket 43 at the end of arm.
The motion of second mode of operation is with reference to Fig. 2 and Fig. 3.Among Fig. 2, the saw blade 13 reciprocating along the A direction is in primary importance, the cam surface 151 of gear wheel 15 does not contact with the riser 412 of cutter lifting plate 41, and just push rod 42 and wheel bracket 43 all are in the home position, and saw blade also is to be in vertical direction along X-axis.Among Fig. 3, reciprocating lever 12 drives saw blade 13 and is in the second place, and the cam surface 151 of gear wheel 15 is urged to the riser 412 of cutter lifting plate 41 at this moment, makes cutter lifting plate 41 rotate around pivot hole 415; And the matrix 411 of cutter lifting plate 41 is urged to push rod 42, makes push rod 42 along himself axis Y generation displacement; Because push rod 42 and wheel bracket 43 mutual butts, make wheel bracket 43 self pivot rotation.Because the guide wheel 44 on the wheel bracket 43 contacts with saw blade 13, the rotation of guide wheel 44 can produce a driving force to saw blade 13, makes reciprocating lever 12 and saw blade 13 produce the swing of C direction in plane, saw blade place.
In sum, when motor-driven saw blade 13 produced along the reciprocating while of X-axis, operation rotary handle 21 can make saw blade 13 produce rotatablely moving around X-axis, this moment, swivel mount 6 just can be with sleeve pipe 22 rotation, and was arranged on push rod 42 on the swivel mount 6 and wheel bracket 43 also to rotate with the same speed of saw blade 13.Because the shape of the matrix 411 of cutter lifting plate 41 includes a circumferential, no matter make push rod 42 rotate to arbitrarily angled can both connecting with cutter lifting plate 41 all the time.So, when saw blade 13 when X-axis rotates, also all the time along sawtooth right direction make reciprocally swinging.
In the present embodiment, also be provided with an adjusting rod 19 on the housing 1.The same with prior art, this adjusting rod 19 has the cam surface of four different-diameters.When adjusting rod 19 rotated to different positions, different cams can both be urged to the matrix 411 of cutter lifting plate 41, made cutter lifting plate 41 will small rotation be arranged around pivot hole 415 when initial position.Because the diameter difference of cam surface, so the amplitude that compressing cutter lifting plate 41 rotates is also different.Like this, just can indicate four gears on housing 1, saw blade 13 is along the amplitude difference of the reciprocally swinging of C direction on each gear.
Because saw blade 13 in cut workpiece, need tightly be pressed on the workpiece, promptly workpiece can have an active force backward to saw blade.When saw blade 13 move again from the position of Fig. 3 the band Fig. 2 the position time, cutter lifting plate 41, push rod 42 and wheel bracket 43 all return to the home position again.Like this, the rotation of gear wheel 15 just can drive the reciprocally swinging of saw blade 13 along the C direction.Because the cutting force that saw blade 13 and reciprocating lever 12 are subjected to when work is bigger, thus between reciprocating lever 12 and sleeve pipe a sheathed fore bearing 25, and between reciprocating lever 12 and adapter sleeve 23 a sheathed ball bearing 24.Described reciprocating lever 12 can slide in fore bearing 25 and ball bearing 24.
When operating this jigsaw 10, may not need saw blade 13 to rotate around X-axis in some broad places.So present embodiment is provided with a retaining mechanism (not shown) on adapter sleeve 23, can adopt traditional pin-and-hole location structure that adapter sleeve 23 is fixed on the position, rotary handle 21 can not be rotated in this position.
The utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
