Pattern conversion and the speed change of power tool 100 are controlled simultaneously, it is easy to operate.Certainly, two operating parts are arranged on shell to distinguish
The position for controlling switch piece and ring gear, to which the pattern conversion of control power tool and speed change also may be used respectively.
Specifically, be equipped between operating parts 52 and ring gear 78 speed change conduit 81 and can in the speed change conduit 81 sliding the
Two cylindrical pins 84, speed change conduit 81 include the circumferentially extending along output rod 6 and are tilted relative to the axis X-X of output rod 6
The second conduit 82 being arranged.In conjunction with Fig. 5 and Fig. 6, when operating parts 52 rotates, the second cylindrical pin 84 is sliding in the second conduit 82
Dynamic, since the axis X-X of 82 opposite output rod 6 of the second conduit tilts, the second cylindrical pin 84 is in inclined second conduit 82
Displacement will be generated along the axial of output rod 6 when middle sliding, to drive ring gear 78 to generate displacement in turn along the axial of output rod 6
Ring gear 78 is set to switch between the first position and the second position.
In the present embodiment, the second conduit 82 is set on operating parts 2, since ring gear 78 is annular in shape, for convenience of ring gear 78
It is connected with operating parts 52, second connecting rod 86 is connected on ring gear 78, the second cylindrical pin 84 is set on second connecting rod 86.Second connects
Bar 86 is identical as the docked mode of switch piece 8 as the docked mode of ring gear 78 as first connecting rod 54, and details are not described herein.
In conjunction with Fig. 5 and Fig. 6, the second cylindrical pin 84 corresponds to ring gear in the position of two ends of the second conduit 82 as a result,
Two extreme positions of 78 movements, to which driving body 9 is corresponding with the first rotating speed or the second rotational speed；And the first cylindrical pin 58
Two extreme positions of the movement of switch piece 8 are corresponded in two terminal positions of the first conduit 56, to make the output rotation of output rod 6
Or it moves back and forth.The present embodiment is preferred, on circumferential the 6 of output rod, what the second cylindrical pin 84 moved in the second conduit 82
Longest distance is identical as the longest distance that the first cylindrical pin 58 moves in the first conduit 56, as a result, when the rotation of operating parts 52 will
Make ring gear 78 along output rod 6 axial movement in place to speed change when, the axial movement along output rod 6 of switch piece 8 is also same
When in place to translative mode, it is simple to operate.
In conjunction with Fig. 5, Fig. 6 and Fig. 7, in the present embodiment, conversion conduit 53 further includes the third slot communicated with the first conduit 56
Road 88, third conduit 88 along the circumferentially extending of output rod 6 and the axis X-X of opposite output rod 6 it is vertical, speed change conduit 81 is also
Include the 4th conduit 90 communicated with the second conduit 82, the 4th conduit 90 circumferentially extends and along output rod 6 with respect to output rod 6
Axis X-X is obliquely installed, and the first cylindrical pin 58, the second cylindrical pin 84 are respectively simultaneously in the first conduit 56 and the second conduit 82
Middle movement and displacement distance in the circumferential direction of output rod 6 is identical；First cylindrical pin 58, the second cylindrical pin 84 respectively simultaneously third
It is moved in conduit 88 and the 4th conduit 90 and displacement distance in the circumferential direction of output rod is identical.First cylindrical pin 58 is along output
It upwardly extends in the week of bar 6 and is slided in the third conduit 88 vertical with the axis X-X of output rod 6, switch piece 8 is along output rod
Axial direction not will produce displacement, to which switch piece 8 is maintained in first position and the second position on a position and then output rod 6
It keeps output rotation or moves back and forth；And the second cylindrical pin 84 is in the circumferentially extending along output rod 6 and relative to the rotation of output rod 6
It is slided in the 4th conduit 90 that axis X-X is obliquely installed, ring gear 78 generates displacement along the axial of output rod 6, to ring gear
78 make driving body 9 respectively with different the first rotating speed and the second rotational speed, and therefore, the power tool 100 of the present embodiment is defeated
When the output of rod 6 rotation or reciprocating motion there is high speed and low speed both of which to be selected for operator, the person's of being conveniently operated use.
Preferably, third conduit 88 corresponds to one end extension of 8 second position of switch piece in the first conduit 58, as a result, this reality
The power tool 100 for applying example when having output rod 6 to export rotary motion there is high speed and low speed both of which to be selected for operator, more
Meet the demand of operator.
It is furthermore preferred that two ends of the 4th conduit 90 and the second conduit 82 away from each other are located at together in the circumferential direction of output rod 6
On one line.The output rod of the power tool 100 of the present embodiment has reciprocal, low speed rotation, three kinds of high speed rotation at a high speed as a result,
Working condition is more in line with the use demand of operator.
The reciprocal state of high speed as shown in Figure 5, the first cylindrical pin 58 are located at the first end of the conduit 56 far from third conduit 58
End, switch piece 8 are located at the first position engaged with the locating piece 40 on shell 2,6 output reciprocating motion of output rod；At the same time,
Second cylindrical pin 84 is located at the second end of the conduit 82 far from the 4th conduit 90, and ring gear 78 is located at the be disengaged from shell
One position, 9 high speed rotation of driving body, the output high speed of final output bar 6 move back and forth.
Then, operating parts 52 rotates, and the first cylindrical pin 58 slides along inclined first conduit 56, and the second cylindrical pin 84 is along inclining
Oblique second conduit 82 sliding, is progressively switch to low speed rotation state as shown in FIG. 6, at this point, the first cylindrical pin 58 is located at the
One conduit 56 is switched to from first position on the second position and shell close to the end of third conduit 88, the axial movement of switch piece 8
Locating piece 40 be detached from, output rod 6 export rotary motion, at the same time, it is close that the second cylindrical pin 84 is moved to the second conduit 82
The end of 4th conduit 90, ring gear 78 move axially to the second position engaged with shell 2,9 low speed rotation of driving body, finally
Output rod 6 exports low-speed rotation.
Then, operating parts 52 continues to rotate, and the first cylindrical pin 58 is in the third conduit vertical with the rotation axis of output rod 6
It is slided in 88, the position of switch piece 8 is constant, and output rod 6 keeps rotation, and at the same time, the second cylindrical pin 84 is along the inclined 4th
The sliding of conduit 90 drives ring gear 78 to move axially, and high speed rotary motion as shown in Figure 7 is progressively switch to, at this point, the first column
Shape pin 58 is located at end of the third conduit 88 far from the first conduit 56, and switch piece 8 does not generate axial movement and remains at second
It sets, output rod 6 keeps the state of rotation, and at the same time, the second cylindrical pin 84 is located at the 4th conduit 90 far from the second conduit 82
