Abstract

A power tool, comprising first and second module, removable from the first module, the first and second modules being insertable into one another along an insertion axis defining an insertion direction, the first module having a pressing inhibiting element, moved along with the second module, and a pressing blocking element, the inhibiting element being turnable with respect to the blocking element about the insertion axis between normal and detaching positions, the second module being held against the first module in the normal position and removable from the first module in the detaching position, the blocking element allowing the inhibiting element to be transferred along the insertion axis toward the first module into a pressing position when the inhibiting element is in the normal position, the blocking element blocking the insert fitting from being transferred into the pressing position when the inhibiting element is in the detaching position.

First claim

The invention claimed is:

1. A power tool, comprising a first module and a second module which can be removed from the first module, wherein the first and second modules can be inserted into one another along an insertion axis defining a direction of insertion, wherein the first module has a pressing inhibiting element, which is moved along with the second module, and a pressing blocking element, wherein the pressing inhibiting element can be turned with respect to the pressing blocking element about the insertion axis between a normal position and a detaching position, wherein the second module is held against the first module in the normal position and can be removed from the first module in the detaching position, wherein the pressing blocking element allows the pressing inhibiting element to be moved along the insertion axis toward a remainder of the first module into a pressing position when the pressing inhibiting element is in the normal position, wherein the pressing blocking element blocks the pressing inhibiting element from being moved into the pressing position when the pressing inhibiting element is in the detaching position, and wherein the first module has a latching mechanism which brings about latching engagement of the pressing inhibiting element with the remainder of the first module in the detaching position when the second module is removed from the first module.

2. The power tool as claimed in claim 1 , wherein the latching mechanism comprises a latching element on the remainder of the first module and a latching fitting on the pressing inhibiting element, or vice versa, and wherein the latching element engages in the latching fitting in order to bring about latching engagement of the pressing inhibiting element with the remainder of the first module in the detaching position.

3. The power tool as claimed in claim 2 , wherein the latching mechanism comprises a latching spring which loads the latching element toward the latching fitting.

4. The power tool as claimed in claim 2 , wherein the second module has a covering element which covers the latching fitting in order to prevent engagement of the latching element in the latching fitting when the second module is held against the first module.

5. The power tool as claimed in claim 4 , wherein the covering element is formed as a driver which engages in the latching fitting in order to transfer a rotational movement of the second module about the insertion axis onto the pressing inhibiting element when the second module is held against the first module.

6. The power tool as claimed in claim 1 , wherein the first module has an insert fitting and the second module has an insert part that can be inserted into the insert fitting along the insertion axis, or vice versa.

7. The power tool as claimed in claim 6 , wherein the insert part in the insert fitting can be turned in a direction of rotation about the insertion axis between an inhibiting position and a passing position, wherein the insert fitting has a plurality of first projections following one another in the direction of insertion, and the insert part has a plurality of second projections following one another in the direction of insertion, wherein in the inhibiting position one of the second projections respectively engages behind one of the first projections in the direction of insertion, and wherein in the passing position the first projections allow the second projections to pass in the direction of insertion.

8. The power tool as claimed in claim 1 , wherein the pressing inhibiting element has a pressing inhibiting contour, a movement of which along the insertion axis is blocked by the pressing blocking element when the pressing inhibiting element is in the detaching position.

9. The power tool as claimed in claim 1 , wherein the pressing inhibiting element comprises a sleeve arranged around the insertion axis.

10. The power tool as claimed in claim 1 , wherein the power tool has a driving-in element for transferring energy to a fastening element to be driven in, and a power-operated driving device for driving the driving-in element.

11. The power tool as claimed in claim 10 , wherein the first module comprises the driving device, the driving-in element, a guiding cylinder for the driving-in element, and/or an operating element.

12. The power tool as claimed in claim 10 , wherein the second module comprises the driving-in element, a guiding cylinder for the driving-in element, an operating element, and/or a magazine for the fastening element.

13. The power tool as claimed in claim 3 , wherein the second module has a covering element which covers the latching fitting in order to prevent engagement of the latching element in the latching fitting when the second module is held against the first module.

14. The power tool as claimed in claim 13 , wherein the covering element is formed as a driver which engages in the latching fitting in order to transfer a rotational movement of the second module about the insertion axis onto the pressing inhibiting element when the second module is held against the first module.

15. The power tool as claimed in claim 2 , wherein the first module has an insert fitting and the second module has an insert part that can be inserted into the insert fitting along the insertion axis, or vice versa.

16. The power tool as claimed in claim 2 , wherein the pressing inhibiting element has a pressing inhibiting contour, a movement of which along the insertion axis is blocked by the pressing blocking element when the pressing inhibiting element is in the detaching position.

17. The power tool as claimed in claim 2 , wherein the pressing inhibiting element comprises a sleeve arranged around the insertion axis.

18. The power tool as claimed in claim 2 , wherein the power tool has a driving-in element for transferring energy to a fastening element to be driven in, and a power-operated driving device for driving the driving-in element.

19. The power tool as claimed in claim 18 , wherein the first module comprises the driving device, the driving-in element, a guiding cylinder for the driving-in element, and/or an operating element.

20. The power tool as claimed in claim 18 , wherein the second module comprises the driving-in element, a guiding cylinder for the driving-in element, an operating element, and/or a magazine for the fastening element.
