Abstract

Claims (18)

1. An attachment device for attachment to a drive device, the attachment device comprising a receptacle for a fluid container and a pressing device for pressing the fluid container to effect dispensing of fluid contained in the fluid container, the pressing device further serving to lock the fluid container in the receptacle so that the fluid container cannot be removed from the receptacle, further comprising a stabilizing handle for gripping the attachment device with one hand of the user and stabilizing it during dispensing of the fluid, wherein the attachment device comprises an actuating element operable by the user to release the locking of the fluid container in the receptacle so that the fluid container can be removed from the receptacle, and wherein the stabilizing handle is the actuating element or the actuating element is arranged in the region of the stabilizing handle so that the user can actuate the actuating element with his hand while the user grips the stabilizing handle with this hand,

wherein the stabilizing handle is the actuating element and the stabilizing handle is displaceable in the longitudinal direction of the attachment device for actuation.

2. The attachment device of claim 1 , further comprising a receiving interface for connecting the attachment device to a drive interface of the drive device.

3. The attachment device according to claim 2 , wherein the stabilizing handle is arranged in the longitudinal direction of the attachment device between the receiving interface and a front end of the receptacle.

4. The attachment device according to a claim 1 , wherein the stabilizing handle is arranged in the longitudinal direction of the attachment device in the same longitudinal region as the receptacle.

5. The attachment device according to claim 1 , wherein the stabilizing handle is designed as a fore-end handle.

6. The attachment device according to claim 1 , wherein the pressing device comprises a pressing element for pressing and for locking the fluid container,

and the attachment device comprises a resetting device which is adapted to automatically move,

in response to the actuation of the actuating element, the pressing element into a release position in which the locking of the fluid container is released.

7. The attachment device according to claim 6 , wherein the resetting device comprises a spring element, the spring force of which serves to move the pressing element into the release position.

8. The attachment device according to claim 6 , further comprising a drive element coupled to the pressing element for driving the pressing element, wherein the resetting device is adapted to disengage the coupling between the drive element and the pressing element in response to actuation of the actuating element.

9. The attachment device according to claim 8 , wherein the pressing element comprises a spindle and the driving element comprises a spindle nut with which the spindle is coupled and drivable.

10. The attachment device according to claim 9 , wherein the spindle nut comprises at least one coupling element displaceable, in response to actuation of the actuation element, from a coupling position in which the coupling element engages a thread of the spindle to a decoupling position in which the coupling element does not engage the thread of the spindle.

11. The attachment device according to claim 1 , further comprising an erecting mechanism triggerable by actuation of the actuating element and adapted to erect the fluid container relative to the receptacle to facilitate removal of the fluid container from the receptacle.

12. A method for operating an attachment device attached to a drive device, the attachment device comprising a receptacle in which a fluid container is arranged and a pressing device for pressing the fluid container to effect dispensing of fluid contained in the fluid container, the pressing device further serving to lock the fluid container in the receptacle so that the fluid container cannot be removed from the receptacle, the attachment device further comprising a stabilizing handle for gripping the attachment device with one hand of the user and stabilizing it during dispensing of the fluid, wherein the attachment device comprises an actuating element operable by the user to release the locking of the fluid container in the receptacle so that the fluid container can be removed from the receptacle, and wherein the stabilizing handle is the actuating element or the actuating element is arranged in the region of the stabilizing handle so that the user can actuate the actuating element with his hand while the user grips the stabilizing handle with this hand, the method comprising the steps: actuating the actuating element to effect a release of the locking of the fluid container and manually removing the unlocked fluid container from the receptacle, wherein the actuating of the actuating element causes an automatic movement of a pressing element into a release position, so that between the actuating of the actuating element and the manual removing of the fluid container no further action of the user is required to be able to remove the fluid container.

13. The method according to claim 12 , wherein the drive device is a screwing and/or drilling device.

14. An attachment device for attachment to a drive device, the attachment device comprising a receptacle for a fluid container and a pressing device for pressing the fluid container to effect dispensing of fluid contained in the fluid container, the pressing device further serving to lock the fluid container in the receptacle so that the fluid container cannot be removed from the receptacle, further comprising a stabilizing handle for gripping the attachment device with one hand of the user and stabilizing it during dispensing of the fluid, wherein the attachment device comprises an actuating element operable by the user to release the locking of the fluid container in the receptacle so that the fluid container can be removed from the receptacle, and

wherein the stabilizing handle is the actuating element or the actuating element is arranged in the region of the stabilizing handle so that the user can actuate the actuating element with his hand while the user grips the stabilizing handle with this hand, wherein the pressing device comprises a pressing element for pressing and for locking the fluid container, and the attachment device comprises a resetting device which is adapted to automatically move, in response to the actuation of the actuating element, the pressing element into a release position in which the locking of the fluid container is released.
