Abstract

The screw holder for a screwdriver is designed to hold, loosen and adjust all types of screw with a slit or cross-slit head. The unit sleeve (1) is mounted movably and rotatably on the screw driver shaft (3) and is so widened in the region of the drive head (2) that by corresponding displacement it can accommodate screws for all types of work. The sleeve is matched in its guide region to the relevant screwdriver shaft dia. and by means of slits serves as a displaceable and rotatable clamping sleeve. The slits are so designed that the sleeve can even be placed over screwdrivers with broad tips. The sleeve can be made from electrically non-conducting material for insulated screwdrivers.

Description

Beschreibungdescription

Die Erfindung betrifft eine "Schrauben-Haltevorrichtung und Abrutschsicherung für Schraubpnzieher zum Festziehen, Lösen und Verstellen aller herkömmlichen Schlitz- sowie Kreuzschlitz-Schrauben." rer Schraubenzieher zua Festziehen, Lösen und Verstellen von Schrauben mit geschlitztem Kopf zahlt zu den meistgebrauchten Werkzeugen aller Branchen, in denen sog. Schlitz- sowie Kreuzschlitz-Schrauben als Verbindungs- bzw. . Befestigungselement verwendet werden.The invention relates to a “screw holding device and anti-slip device for screwdrivers for tightening, loosening and adjusting all conventional slotted as well as cross-head screws. A screwdriver for tightening, loosening and adjusting of slotted head screws is one of the most widely used tools of all Industries in which so-called slotted and Phillips screws are used as connecting or . Fastening element can be used.

I?iese haufige Verwendung stellt an die Ausführung sowie an die Handhabung dieses Werkzeuges die größten Anforderungen.This frequent use places itself in the execution as well as in the handling this tool meets the greatest demands.

Itierzu gehören, je nach Einsatz, neben einer entsvrechenden Festigkeit des verwendeten Materials ganz besonders die leicht e und sichere handhabung auch bei oft notwendig hohem Kraftaufwand und bei Verbindungspunkten an einem schwer zugänglichen Bauteil (enger Spalt, verdeckte Schraubstellen usw.).It is part of it, depending on the application, in addition to a corresponding strength of the material used, especially the easy and safe handling if a lot of force is often necessary and if there are connection points on one difficult accessible component (narrow gap, hidden screw points, etc.).

Die Ausführungen aller herkömmlichen Schraubenzieher für die o.g. Bereiche weisen auch bei der Verwendung durch Fachkrefte noch einige erhebliche Mängel auf: 1. Abrutschen des Schraubenziehers bei: notwendig hohem Kraftaufwand, beschädigten Schraubenköpfen, schwer zugänglichen oder verdeckten Verschraubungsstellen sowie bei Arbeiten iiber Kopf; 2. Yeine Schrauben-Haltevorrichtung bei allen auszuführenden arbeiten und damit: erschwertes Setzen von Schrauben, herausfallen gelöster Schrauben.The versions of all conventional screwdrivers for the above Areas still show some significant even when used by specialists Defects on: 1. Slipping of the screwdriver in the case of: necessary high effort, damaged screw heads, inaccessible or hidden screw connections as well as when working overhead; 2. A screw holding device for all to be performed work and with it: difficult setting of screws, loose screws falling out.

3. Verletzungsmöglichkeit.3. Possibility of Injury.

Der Erfindung liegt die Aufgabe zugrunde, diese Mängel vollkommen zu beseitigen und die Verwendung dieses Werkzeuges f;r jeden Benutzer leichter und sicherer zu machen.The invention is based on the object of eliminating these shortcomings to eliminate and use this tool easier and for every user make it safer.

Nach der Erfindung ergeben sich folgende sehr bedeutende Vorteile: 1. Kein Abrutschen des Schraubenziehers bei allen auszuführenden Arbeiten durch die vorgesehene Abrutschsicherung.According to the invention, the following very significant advantages result: 1. No slipping of the screwdriver during any work to be carried out the intended slip protection.

2. Leichtes Setzen und Halten gelöster Schrauben auch bei schwer zugänglichen Bauteilen und bei Arbeiten über Kopf durch die vorgesehene Schrauben-Haltevorrichtung.2. Easy setting and holding of loosened screws even with difficult to access Components and when working overhead through the screw holding device provided.

3. Keine Verletzungsmöglichkeit, da die verschiebbare Hülse bei allen auszuführenden Arbeiten als Haltegriff dient und dadurch Verletzungen durch beschädigte Schraubenköpfe (Gradbildung) und die nicht mehr vorhandene Gefahr des Abrutschens durch die über den Schraubenzieherkopf hinausragende Hülse vermieden werden.3. No possibility of injury, as the sliding sleeve on all work to be carried out serves as a handle and thereby injuries from damaged Screw heads (formation of degrees) and the no longer existing risk of slipping can be avoided by the sleeve protruding beyond the screwdriver head.

Die Erfindung wird auf der Zeichnung A veranschaulicht.The invention is illustrated in drawing A.
