  • the lamp housing is composed of two, preferably mirror-symmetrically designed housing shells, which abut one another along a plane running through the housing axis.
  • the positive connection is realized by at least two mutually corresponding, each formed on the inner wall of the lamp housing and on the outer wall of the machine housing, the number of edges of the polygon corresponds to the number of possible working positions of the angular working head.
  • the angular working head is adjustable in a total of eight rotational positions of 45 ° relative to the machine housing
  • the polygons are each designed as octagon, resulting in a total of eight rotating positions of the lamp housing, one of which is permanently assigned to a working position of the angular working head.
  • the two housing shells are held together by clamping devices.
  • the lamp housing can be moved on the polygon of the machine housing by loosening the clamping device. After setting the desired rotational position, the two housing shells are connected again by the clamping device.
  • FIG. 1 is a partial side view of an angle screwdriver, partially cut
  • Fig. 2 is a side view of a lighting device on

  • the receptacle 11, which partially protrudes from the machine housing 10 is inserted into the machine housing 10 with its rear end facing away from the angled screw head 12 and screwed into it.
  • the receptacle 11 has several, in the exemplary embodiment a total of four, pressed-in cylinder pins 13, and the angled screw head 12 has cutouts 14 offset in the circumferential direction on its end facing the cylindrical pins 13 (in the exemplary embodiment a total of eight), into which the cylindrical pins 13 when the angled screw head 12 is attached intervene axially and positively.
  • Dowel pins 13 and recesses 14 are each equidistantly above arranged circumferentially distributed, the angular distance between the cylindrical pins 13 from each other corresponding to twice the angular distance of the recesses 14 from each other, so that always four cylindrical pins 13 engage in four of the eight recesses 14 in the angled screw head 12.
  • the angle screw head 12 After removing the angled screw head 12 from the cylinder pins 13, it can be rotated by an angle of rotation, which corresponds to the distance between two recesses 14, in the exemplary embodiment by 45 °, and pushed back onto the cylinder pins 13 with its recesses 14.
  • the angle screw head 12 can thus be arranged offset in eight rotational positions relative to the housing axis 101 of the machine housing 10, so that the angle screwdriver has a total of eight different working positions for the screwing tool when the position of the machine housing 10 is unchanged. Each screw position is offset by 45 ° from the other.
  • a union nut 15 is provided, which can be stolen on an external thread of the receptacle 11.
  • a bevel gear 16 consisting of two intermeshing bevel gears 16 is arranged, of which one bevel gear 17 sits on a drive shaft 18 and the other bevel gear 19 on an output shaft 20 oriented at right angles to the drive shaft 18.
  • Drive shaft 18 and output shaft 20 are rotatably mounted in the angle screw head 12.
  • the drive shaft 18 is driven by an electric motor (not shown here) accommodated in the machine housing 10 with the interposition of a step-up gear and a torque limiter.
  • a chuck 21 for receiving a screwing tool is connected in a rotationally fixed manner to the output shaft 20.
  • the angle screwdriver has an illumination device 22 for illuminating the screwing point during a screwing process.
  • Lighting device 22 comprises a hollow cylindrical lamp housing 23, in which a lamp shaft 231 is formed, and a light source in the form of an LED 24, which is inserted into the lamp shaft 231 and via a power cable 33 to a power source, for. B. the battery of the designed as a cordless screwdriver, is connected.
  • the lamp housing 23 is placed on the working end of the machine housing 10 and clamped so that it is not axially removable.
  • the lamp shaft 231 is formed on one side of the lamp housing 23 in such a way that the shaft axis 231a extends at an acute angle to the housing axis 101 of the machine housing 10 (and to the axis of the lamp housing 23 arranged coaxially therewith) and the shaft opening 231b from which the light of the LED 24 emerges, points to the angle screw head 12.
  • the lamp housing 23 is adjustable on the machine housing 10 in discrete rotational positions, one rotational position in each case corresponding to one of the working positions of the angled screw head 12.
  • the discrete rotational positions are each predetermined by positive locking between the machine housing 10 and lamp housing 23.
  • the lamp housing 23 shown in different views and sections in FIGS. 2 to 7 is composed of two housing shells 25, 26, preferably made of plastic, which abut each other along a plane running through the housing axis 101 of the machine housing 10 (FIGS. 4 and 5). Half of the lamp shaft 231 is formed in each housing shell 25, 26. To produce the positive connection in the rotational positions of the lamp housing 23 (in the exemplary embodiment! Corresponding to the eight working positions of the angled screw head 12 eight
  • An octagon 27 (FIGS. 3 and 6) is formed on the inner wall of the lamp housing 23, which corresponds to an identical octagon 34 on the outer wall of the machine housing 10, as indicated in FIG.
  • the octagon 27 and correspondingly the octagon 34 of the machine housing 10 have only a small axial depth or width.
  • Half of the octagon 27 is formed in each case in the housing shell 25 and in the housing shell 26. After placing the two housing shells 25, 26 on the machine housing 10, the two housing shells 25, 26 are releasably connected to one another by clamping means.
  • a snap ring 28 and a clip ring 29, preferably made of plastic, are provided as clamping means, which enclose the two housing shells 25, 26.
  • the snap ring 28 is inserted in an annular groove 30 arranged on the rear end of the lamp housing 23 facing away from the angled screw head 12, while the clip ring 29 is placed on the end of an end of the lamp housing 23 facing the other angled screw head 12 molded on axially projecting annular web 31 is clipped.
  • the lamp shaft 231 with the LED 24 lies in the lower region of the machine housing 10, so that the LED 24 arranged in the housing shaft 231 automatically illuminates a screwing tool inserted into the chuck 21 of the angle screw head 12. If the angled screw head 12 is pivoted around the housing axis 101 of the machine housing 10 with the alignment of the machine housing 10 unchanged, for which purpose the union nut 15 is loosened after the above, the angled screw head 12 has to be pivoted about the housing axis 101 of the machine housing 10 and the union nut 15 has to be screwed on again then the lamp housing 23 must be rotated by the same angle of rotation.
