Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen Schlagschrauber zu schaffen, der eine reibungslose und leichte Handhabung aufweist.The invention has for its object to provide an impact wrench, which has a smooth and easy handling.
Der Erfindung liegt als weitere Aufgabe zugrunde, einen Schlagschrauber zu schaffen, der einen Einfluss auf die Querschnittfläche des Lufteintrittskanals und des Luftaustrittskanals vermeidet.The invention has as its further object to provide an impact wrench which avoids an influence on the cross-sectional area of the air inlet duct and the air outlet duct.
Diese Aufgaben werden durch den erfindungsgemäßen Schlagschrauber gelöst, der umfasst:
ein Außengehäuse, das einen Aufnahmeraum und einen Handgriff aufweist, wobei der Handgriff einen Lufteintrittskanal besitzt,
ein Motorgehäuse, das im Aufnahmeraum des Außengehäuses angeordnet ist und auf der Unterseite eine Aufnahmeausnehmung aufweist, deren Innenwand an einer Seite mit einem Vorwärtsdreh-Lufteintrittskanal und einem Rückwärtsdreh-Lufteintrittskanal verbunden ist, wobei auf der Unterseite des Motorgehäuses eine Durchgangsbohrung vorgesehen ist, die mit der anderen Seite der Innenwand der Aufnahmeausnehmung verbunden ist,
einen Schalter, der unter dem Motorgehäuse angeordnet ist und den Lufteintrittskanal des Handgriffs öffnen und schließen kann, so dass die Druckluft im Lufteintrittskanal durch die Aufnahmeausnehmung in das Motorgehäuse eintreten oder abgesperrt werden kann,
einen Umschalter, der ein Umschaltventil, das in der Aufnahmeausnehmung des Motorgehäuses aufgenommen ist, und eine Druckstange aufweist, die in der Durchgangsbohrung des Motorgehäuses aufgenommen ist und aus den beiden Seiten des Außengehäuses herausragt, wobei die Druckstange und das Umschaltventil auf einer horizontalen Linie miteinander verbunden sind, wobei wenn die Druckstange gedrückt wird, das Umschaltventil in der Aufnahmeausnehmung gedreht wird, wobei die Axialrichtung des Umschaltventils vertikal zu der Axialrichtung des Schalters verläuft, wobei das Umschaltventil in der Unterseite entsprechend dem Lufteintrittskanal des Handgriffs eine Lufteintrittsöffnung und an der der Druckstange abgewandten Seite eine Durchgangsöffnung besitzt, die mit der Lufteintrittsöffnung verbunden ist, wobei wenn das Umschaltventil von der Druckstange gedreht wird, die Durchgangsöffnung mit dem Vorwärtsdreh-Lufteintrittskanal oder dem Rückwärtsdreh-Lufteintrittskanal in Fluchtung gebracht werden kann.These objects are achieved by the impact wrench according to the invention, which comprises:
an outer housing having a receiving space and a handle, the handle having an air inlet channel,
a motor housing, which is arranged in the receiving space of the outer housing and having a receiving recess on the underside, whose inner wall is connected on one side with a forward rotary air inlet channel and a reverse rotation air inlet channel, wherein on the underside of the motor housing, a through hole is provided which communicates with the connected to the other side of the inner wall of the receiving recess,
a switch which is disposed under the motor housing and can open and close the air inlet channel of the handle, so that the compressed air in the air inlet channel can enter or be blocked by the receiving recess in the motor housing,
a change-over switch having a changeover valve accommodated in the accommodating recess of the motor housing and a push rod received in the through hole of the motor housing and protruding from both sides of the outer housing, the push rod and the changeover valve being connected to each other in a horizontal line are, wherein when the push rod is pressed, the switching valve is rotated in the receiving recess, wherein the axial direction of the switching valve is vertical to the axial direction of the switch, wherein the switching valve in the bottom corresponding to the air inlet channel of the handle an air inlet opening and on the side facing away from the push rod has a through hole, which is connected to the air inlet opening, wherein when the switching valve is rotated by the push rod, the through hole with the forward rotary air inlet duct or the reverse rotary air inlet duct in alignment ben can be looked after.
