1. hand-held machine tool device, comprising:

  • a percussion unit (10), the percussion unit (10) include oneJackshaft (64);

    One driving unit (12), the driving unit have a driven axis (14), and the driven axis is relative to punchingThe rotation axis (16) for the jackshaft (64) for hitting mechanism unit (10) is arranged with being staggered;

    It include the planetary gear of shift-variable with oneThe gear unit (18) of transmission device, the gear unit is at least two position of the switch and has a rotation axis(20), which corresponds to the rotation axis (16) of percussion unit (10), wherein the gear unit (18) is oneIt is arranged between driving unit (12) and percussion unit (10) and the driving of motor drive shaft (54) on a machine direction (22)Movement is transmitted to the jackshaft (64) by the planet gear transmission device of shift-variable and hand-held machine tool device is equipped withAt least one coupling unit (28), the coupling unit are arranged for keeping percussion unit (10) and gear unit (18) removableCouple with unloading and it is described drive move to the jackshaft (64) the transmitting and the percussion unit (10) instituteStating coupling is realized by the planet carrier (76) of the planet gear transmission device, wherein the coupling unit includes twoCoupling element (96,98), a face by the internally positioned cone on the side of planet carrier in two coupling elementsIt constitutes, another in two coupling elements is by the face for being located at external cone on the oscillation bearing of percussion unitIt constitutes, and forms friction lock between two coupling elements.
