Embodiment Construction

[0074] The hand-held power tool 10 has a housing 11 , in the interior of which a drive train 20 is arranged. Hand-held power tool 10 is, for example, a screwing instrument, a drilling instrument or both. The housing 11 can be comfortably gripped by an operator at a grip section 12 . The drive train 20 is accommodated in an upper housing section 13 that extends at an angle relative to the handle section 12 in the form of a pistol.

[0075] The front housing section 14 extends in front of a grip section 12 , which can be grasped, for example, by hand, wherein the grip section 12 and the housing section 14 are connected to one another via a lower housing section.

[0076]Connections, for example for grid cables 17 , are located on the lower housing section. It is also possible to arrange an accumulator or another mobile energy store on the housing section or, as shown in the exemplary embodiment, in the region of the front housing section 14 .

[0077] In each case it is poss...

Abstract

The invention relates to a portable power tool (10), in particular a screwing device and/or drilling device, having a drive motor (16) for driving a transmission drive (25) of a transmission (30) which has a transmission output (26) for driving a tool receptacle (18) of the portable power tool (10) and a first gear stage (41) and a second gear stage (42), wherein the transmission has a first blocking device (61) for blocking a gearing element, forming a ratchet gearing element (43), of the first gear stage (41) and a second blocking device (62) for blocking a gearing element, forming a ratchetgearing element, of the second gear stage (42), wherein the gear stage having the respectively blocked ratchet gearing element transmits a torque from the transmission drive (25) to the transmissionoutput (26), wherein a direction of rotation of the drive motor (16) is changeable and, depending on the direction of rotation of the drive motor (16), the first gear stage (41) or the second gear stage (42) transmits a torque from the transmission drive (25) to the transmission output (26). Provision is made for one of the two gear stages to effect a reversal in the direction of rotation betweenthe transmission drive (25) and the transmission output (26).

Description

technical field [0001] The invention relates to a hand-held power tool, in particular a screwing instrument (Schraubgerät) and / or a drilling instrument, with a drive motor for driving a transmission drive of a transmission with a The transmission output of the tool receptacle of the hand-held power tool and the first transmission stage and the second transmission stage, wherein the transmission has a design for blocking the first transmission stage A first locking mechanism for locking the transmission element of the transmission element and a second locking mechanism for locking the transmission element of the second transmission stage forming a locking transmission element, wherein the transmission stage is in the corresponding locking transfers torque from the transmission driver to the transmission follower in the absence of a locked transmission element, wherein the direction of rotation of the drive motor can be reversed and the first transmission stage or the A second ...
