Hammer drill with wobble mechanism and hollow drive shaft

A hand power tool, comprising a housing;

• a drive motor and a gear mechanism arranged in said housing;
• a tool receptacle in which a tool is guidable;
• a gear wheel via which a rotary sleeve is driven in rotation from said drive motor and said gear mechanism and thereby said tool receptacle is driven in rotation;
• a hammering mechanism located inside said rotary sleeve and drivable translationally via a wobble gear mechanism, said gear mechanism having a driving gear wheel meshing with a motor pinion and arranged on a shaft by which said wobble gear mechanism is drivable to revolve, said shaft being configured as a hollow shaft on which said driving gear wheel is retained nondisplaceably and in a manner fixed against rotation, said wobble gear mechanism being located adjacent to said driving gear wheel on said shaft rotatably and couplably to said hollow shaft,
• wherein said hollow shaft includes transmission elements supported in radially passable oblong slots, by means of which transmission elements said wobble gear mechanism is couplable with said hollow shaft in a circumferential direction for rotary slaving,
• wherein said wobble gear mechanism has a wobble body provided on its inner circumferential face with longitudinal recesses with which said transmission elements are meshable for form-locking rotary slaving, and with an encompassing groove in which said transmission elements are capable of revolving freely without a form-locking connection with said wobble gear mechanism, and
• further comprising a switching shaft which is supported axially displaceably inside said hollow shaft and on its outer circumferential face has an encompassing recess into which said transmission elements, protruding radially inwards past said hollow shaft, engage, said switching shaft being displaceable together with said transmission elements relative to said hollow shaft and said wobble gear mechanism between positions in which said transmission elements mesh in a form-locking manner for rotary slaving with said longitudinal recesses of said wobble gear mechanism, and a position in which said transmission elements engage inside said encompassing groove of said wobble gear mechanism and revolve freely therein.
