- Cylindrical pins 13 and recesses 14 are each equidistant over arranged distributed around the circumference, wherein the rotational angular distance of the cylindrical pins 13 from each other twice the angular distance of the recesses 14 corresponds to each other, so that in each case four cylinder pins 13 engage in four of the total of eight recesses 14 in the Winkelschraubkopf 12.
- Winkelschraubkopfs 12 of the cylinder pins 13 After subtracting the Winkelschraubkopfs 12 of the cylinder pins 13, this can in each case a rotation angle corresponding to the distance between two recesses 14 from each other, ie in the exemplary embodiment by 45 °, rotated and pushed with its recesses 14 back to the cylinder pins 13.
- the Winkelschraubkopf 12 can be arranged offset in eight rotational positions relative to the housing axis 101 of the machine housing 10, so that the angle wrench with unchanged position of the machine housing 10 has a total of eight different working positions for the screwing. Each screw position is offset from the other by 45 ° rotation angle.
- a union nut 15 is provided, which is screwed onto an external thread of the receptacle 11.
- Winkelschraubkopf 12 consisting of two intermeshing bevel gears existing angle gear 16 is arranged, of which the one bevel gear 17 on a drive shaft 18 and the other bevel gear 19 is rotatably seated on a drive shaft 18 at right angles aligned output shaft 20.
- Drive shaft 18 and output shaft 20 are rotatably mounted in Winkelschraubkopf 12.
- the drive shaft 18 is driven by a not shown here, recorded in the machine housing 10 electric motor with the interposition of a transmission gear and a torque limiter. With the output shaft 20, a chuck 21 for receiving a screwing is rotatably connected.
- the angle wrench has an illumination device 22 for illuminating the screw point during a screwing operation.
- the lighting device 22 comprises a hollow cylindrical lamp housing 23, in 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 a power cable 33 to a power source, for. B. the battery of the designed as a screwdriver angle wrench is connected.
- the lamp housing 23 is placed on the working end of the machine housing 10 and clamped so that it is not removable axially.
- the lamp shaft 231 is formed on one side of the lamp housing 23, that the shaft axis 231 a at an acute angle to the housing axis 101 of the machine housing 10 (and the axis of the coaxially arranged lamp housing 23) extends and the shaft opening 231 b, from which the light the LED 24 exits, the Winkelschraubkopf 12 points.
- the lamp housing 23 is adjustable on the machine housing 10 in discrete rotational positions, wherein each one rotational position coincides with one of the working positions of the Winkelschraubkopfs 12.
- the discrete rotational positions are in each case predetermined by positive engagement between the machine housing 10 and the lamp housing 23.
- the lamp housing 23 shown in various views and sections in FIGS. 2 to 7 is composed of two preferably made of plastic housing shells 25, 26 which abut one another along a plane passing through the housing axis 101 of the machine housing 10 (FIGS. 4 and 5).
- each housing shell 25, 26 of the lamp shaft 231 is formed half each.
