Detailed description of the invention
Accompanying drawing shows a kind of instrument, has housing 1a, 1b, 1c, 1d, oscillating unit 4, for the insert adapter 5 of fastening means blade, motor 2, motor bearings 16, motor switch 17, and has the motor output shaft 3 of electric machine rotational axis 18.This instrument is the multi-purpose tool of a kind of vibration, and it has the eccentric shaft 8 being connected to described motor output shaft 3 and being rotated by motor output shaft 3.Eccentric shaft 8 has the first eccentric part 9 being connected with oscillating unit 4 and the second eccentric part 11 being connected with balance weight 13.First eccentric part 9 has the first eccentric rotary axle 19 offset with the first offset direction from electric machine rotational axis 18, and the second eccentric part 11 has the second eccentric rotary axle 20 offset with the second offset direction from electric machine rotational axis 18.First eccentric part 9 is with the mobile oscillating unit 4 that drives of the first vibration, and the second eccentric part 11 drives balance weight 13 with mobile relative to the second vibration of the first vibration movement, and balance weight 13 thus reduces the vibration that oscillating unit 4 is caused during using this instrument.
In a kind of preferred implementation of this instrument, the first offset direction offsets so that 180 degree are separated by with the second offset direction.First eccentric rotary axle 19 offsets from electric machine rotational axis 18 with the first offset distance A, and the second eccentric rotary axle 20 offsets from electric machine rotational axis 18 with the second offset distance B.First offset distance A and the second offset distance B is identical.
Balance weight 13 has hole therethrough, and balance weight 13 is placed on above the second eccentric part 11, makes the second eccentric part 11 run through described hole and position.Between the second eccentric part bearing 12 hole in the second eccentric part 11 and described balance weight 13.Balance weight 13 has the first linear bearing 14 and the second linear bearing 15, and the second vibration movement is moving left and right between the first linear bearing 14 and the second linear bearing 15.
Oscillating unit 4 includes that oscillating unit inputs connection 6.Oscillating unit input connects 6 and is connected to the first eccentric part 9 and is pivotably mounted on bearing 7.First eccentric part bearing 10 is connected between 6 with oscillating unit input at the first eccentric part 9.First vibration is mobile is around moving back and forth of bearing 7 rotation.
Skilled artisan would appreciate that in the case of the spirit or scope fully described without prejudice to this utility model, the detailed description of the invention shown in this utility model can be carried out more change and/or change.Embodiment the most of the present utility model is merely to illustrate various aspects of the present utility model rather than limits this utility model.
