Description
Schraubenzieher mit Einrichtung zum Halten der Schraube. Die Erfindung betrifft einen Schrauben zieher mit Einrichtung zum Halten der Schraube, welcher sich dadurch auszeichnet, dass er auf einem Teil seines Stiels mit Ge winde versehen ist,- auf welches eine zuge- höiige,Hiilse aufschraubbar ist, die an :ihrem Vorderteil einen zum Anlegen gegen die Schraube bestimmten gelochten Boden auf weist:
Die Zeichnung veranschaulicht ein Aus- führungsbeispiel des Erfindungsgegenstandes in hig. 1 in Seitenansicht; und in Fig. 2 im Schnitte nach der Linie II-II der Fig. 1 in grösserem Massstube.
1 ist der Stiel des Schraubenziehers und 2 seine Stahlschneide. Der Stiel ist auf sei nem Mittelteil mit Gewinde '3 versehen. Die Hülse 4 ist an ihrem Hinterteil 5 mit zu dem Gewinde 3 passendem Innengewinde ausgestattet; während ihre zylindrische<B>Öff-</B> nung 6 etwas weiter als der Stiel 1 ist.
Die Hülse 4 besitzt an ihrem Vorderteil 7 eine seitliche Ausnehmung 8 und vorne einen Boden 9; welcher ausser einer Lochung 10 mit einem radialen Schlitz 11 versehen ist. Der Boden zeigt an der Innenseite eineu ko nischen Sitz 12.
Zwecks Verschraubens wird der Schrau benbolzen so durch den Schlitz<B>11</B> und in die Lochung 10 von der Seite eingelegt, dass der Schraubenkopf 13 mit seinem konischen Teil sich an den konischen Sitz 12 anlegt, worauf die Stahlschneide 2 durch Drehen des Stiels 1 in der mit der Hand festgehaltenen Hülse dem Schraubenkopfe genähert wird. Durch Drehen des Schrapbenbolzens von Hand lässt sich die Rille des Schraubenkopfes in Linie mit der Stahlschneide bringen, so dass letztere in die Rille eintreten und durch wei teres Drehen des Stiels 1 in der Hülse 4 an die Schraube angedrückt werden kann, wo durch die Schraube den Halt erhält.
Screwdriver with a device for holding the screw. The invention relates to a screwdriver with a device for holding the screw, which is characterized in that it is provided with a thread on a part of its handle, - on which an associated sleeve can be screwed, which on: its front part to Applying against the screw certain perforated bottom has:
The drawing illustrates an exemplary embodiment of the subject matter of the invention in hig. 1 in side view; and in Fig. 2 in section along the line II-II of Fig. 1 on a larger scale.
1 is the handle of the screwdriver and 2 is its steel blade. The handle is threaded '3 on its middle part. The sleeve 4 is equipped on its rear part 5 with an internal thread matching the thread 3; while its cylindrical <B> opening </B> 6 is slightly wider than the stem 1.
The sleeve 4 has a lateral recess 8 on its front part 7 and a bottom 9 at the front; which apart from a perforation 10 is provided with a radial slot 11. The bottom shows a conical seat 12 on the inside.
For the purpose of screwing the screw is benbolzen so inserted through the slot 11 and into the perforation 10 from the side that the screw head 13 rests with its conical part on the conical seat 12, whereupon the steel cutter 2 by turning of the handle 1 in the hand-held sleeve is approached to the screw head. By turning the scraper bolt by hand, the groove of the screw head can be brought into line with the steel cutter so that the latter can enter the groove and, by further turning the handle 1 in the sleeve 4, can be pressed against the screw, where the screw allows the Get hold.
