Claim:
A hand-held power tool, comprising: a main housing ( 4 ); a tool spindle ( 10 ) at least partially located in the housing ( 4 ), extending along an operational axis ( 12 ) and carrying a chuck ( 14 ); a handle housing ( 16 ) on which a handle ( 18 ) is formed; and a connection device ( 28 ) for securing the handle housing ( 16 ) to a rear side ( 34 ) of the main housing ( 4 ) remote from the chuck ( 14 ), the connection device ( 28 ) having: a first assembly ( 50 ) including: a first engagement member ( 58 ) associated with the handle housing ( 16 ); a first elastic element ( 56 ); and a second engagement member ( 52 ) associated with the main housing ( 4 ), wherein the second engagement member ( 52 ) has a convex shape directed towards an upper side of the power tool; wherein the first engagement member ( 58 ) has a concave receptacle ( 60 ) for receiving the first elastic element ( 56 ); and wherein the first elastic element ( 56 ) has a convex receiving space ( 62 ) for receiving the convex shape of the second engagement member ( 58 ) such that the second engagement member ( 52 ) is loosely engaged with the first engagement member ( 58 ); wherein the first assembly ( 50 ) of the first engagement member ( 58 ), the first elastic element ( 56 ), and the second engagement member ( 52 ) causes the main housing ( 4 ) to engage the handle housing ( 16 ) in a first engagement; and a second assembly ( 48 ) including: an eyelet element ( 38 ) orientated along a vertical direction from the upper side to a lower side of the power tool, with the vertical direction being perpendicular to the operational axis ( 12 ); two housing webs ( 36 ) separated along the vertical direction with each of the two housing webs ( 36 ) provided with through holes ( 30 ) being aligned along the vertical direction; a second elastic member ( 40 ) having a through hole ( 44 ) and is received in the eyelet element ( 38 ) and also being received between the two housing webs ( 36 ) such that the through holes ( 30 , 44 ) of the two housing webs ( 36 ) and of the second elastic element ( 40 ), respectively, are aligned; and a pin-shaped projection ( 46 ) which is inserted through the through holes ( 30 , 44 ) for formlockingly connecting the the eyelet element ( 38 ) and the two housing webs ( 36 ), wherein the second assembly ( 48 ) of the eyelet element ( 38 ), the two housing webs ( 36 ), the second elastic member ( 40 ), and the pin-shaped projection ( 46 ) causes the main housing ( 4 ) to engage the handle housing ( 16 ) in a second engagement; wherein upon formation of a formlocking connection of the eyelet element ( 38 ) with the two housing webs ( 36 ), simultaneously, absence of loose engagement in the first assembly ( 50 ) of the first engagement member ( 58 ), the first elastic element ( 56 ), and the second engagement member ( 52 ) is ensured; and wherein the first assembly ( 50 ) and the second assembly ( 48 ) are separated along the vertical direction, with the vertical direction being perpendicular to the operational axis ( 12 ).
