The invention relates to a device for the production of, pipeline and switch

,,,. “Recesses; _:, In Mauerwerk.yom homes, and the like, which consists of ¹ eiiier hand drill on..

_i: 5, r which a drilling or milling tool and a guide body are inserted. To now; with this device also walls and ceilings for the implementation of lines, at their corners; to be able to drill through, you need a drill pipe, which as

ίο an angled intermediate piece provided with a bucket cardan shaft and attached to the ¹ drill.

The invention ¹ now has the task of making the 'fastening and loosening of the angled drill rods and of course also of the straight drill rods, against which the first drill rod is exchanged, as simple as possible. This is done by the fact that the bearing piece for the articulated shaft at its rear angled end with: a "plug-in plate for clamping running parallel to the drilling machine spindle; in a clamping slot arranged on the housing of the drilling machine and the connection of both the straight drill rod and the the hinge shaft of-Winkelbohrgestänge "with that terminal end of the Bohirmaischinemspinder by a conventional ^male: Komuskupplung takes place, which is provided for tightening with some Gewindegämgeni ^.isttiDurch: pull the 'latter threads located Bqhir-!

Spindle and PTO shaft automatically ^1! "When loosening this connection ¹ , key surfaces" or pin holes are attached to the spindle and to the shaft.

This appropriate training - this device

allows effortless and quick connection and disconnection of the drill rod or the tools themselves with or from the hand drill. In particular, the previously necessary disintegration of the ... two funny parts. Is no longer necessary, which prevents them from being damaged. ^λ

In the drawing, -e'ini is exec ^; ngsexample ^; of, according to the invention! Device impefspefctivischer'Dar - position shown. The hollow-cylinder-shaped housing forming the bearing piece for the articulated shaft is denoted by 1, at the angled end of which the swallow-wedge-shaped fastening plate 2 is attached. With 3 the propeller shaft is designated, the connection piece 4 has a Morsekomus 5. The thread 6, which consists of a few turns, closes on this towards the outside, and 7 is a thread at the end. ußs tuck attached key surface !, next to which there is an additional. Dormloch 8 is located.

If the angle drill rods are to be connected to the Hamdbohrmaschine, the plate 2 is pushed into the clamping prism of the ¹ drill, which is ^{no longer shown in drawing 1.} At the same time, the conical end 9 of the drilling machine spindle is pushed into the Morsekomus 5 of the cardan shaft 3. By turning the spindle 10 slightly by hand, the thread 6 of the spindle 10 engages in that of the connection piece 4 of the shaft 3, and the device is ready for operation. When the drill is switched on, the end of the spindle rotates. 10 by itself firmly in the connector 4 of the cardan shaft 3 and takes it with; then tighten the locking screw of the clamping prism,

If you want to do, stop working with the Angle drill pipe this from; disconnect the drill again, so one loosens the fastening screwdriver of the clamping prism and 'screws with the help of f two keys, which you put in the wrench flats 7 and 11 ■ (the latter is attached to the spindle 10) with just a few turns of spindle 10 and drive shaft 3 apart. Then it can be done Easily detach the additional device from the drill and there is no disintegration between the two Parts needed.

The same procedure is used when the drilling or . Milling tool without the interposition of the angle drill rod. directly on the drilling machine spindle should be put on, so that there is also in this If you don't need to use a dismantling device and the tools are spared: become. -85 "
