Description

Technical Field

[0001] The invention relates to a holding device for a handheld power tool having a tool receptacle which is configured at least for receiving an embedded tool, in particular a screwdriver bit, wherein the holding device is provided for holding a fastening element, in particular a screw element. Background Art

[0002] Such a holding device for a handheld power tool is known in the prior art, and the handheld power tool has a tool receiving portion configured to receive an embedded tool configured as a screwdriver head. The holding device is provided for holding a fastening element configured as a screw element, and has a first holding unit for fixing to the handheld power tool and a second holding unit axially movable on the first holding unit for holding the screw element. The second holding unit can be arranged in a parking position and in a working position, in which the screw element can be held. Summary of the invention

[0003] The present invention provides a holding device for a handheld power tool, the handheld power tool having a tool receiving portion configured to receive at least an embedded tool, in particular a screwdriver head, wherein the holding device is configured to hold a fastening element, in particular a screw element. The holding device has a first holding unit for fixing the holding device on the handheld power tool, and a second holding unit for holding the fastening element, in particular a screw element, wherein the second holding unit is axially movable on the first holding unit, wherein the second holding unit can be arranged in a parking position and a working position, in which the fastening element can be held. The first holding unit is equipped with a locking element, which can be rotated from a locking position to a release position along the circumferential direction of the holding device.

[0004] The invention thus achieves the provision of a holding device in which the second holding unit can be locked by a locking element assigned to the first holding unit when holding the fastening element. The holding device can thus be used to construct a stable and robust depth stop.

[0005] The locking element preferably locks the second holding unit in a locking position in order to prevent an axial movement of the second holding unit from the working position into the parking position.

[0006] In this way, when configuring the depth stop required for a specific working purpose, an unintentional insertion or immersion of the second holding unit into the first holding unit can be safely and reliably prevented.

[0007] Preferably, in the release position, the locking element releases the second holding unit, so that the second holding unit can be moved axially from the working position into the parking position.

[0008] The tool receptacle is thus easily accessible, so that the respectively used screwdriver head can be conveniently replaced.

[0009] According to one embodiment, the first holding unit has at least one groove on its outer circumference, and the locking element is configured to have at least one guide element on its inner circumference that can be guided in the at least one groove so as to be rotatably arranged on the first holding unit.

[0010] A safe and reliable rotatably movable arrangement of the locking element on the first holding unit can thus be achieved.

[0011] The first holding unit preferably has a plurality of first webs which are arranged in the circumferential direction and are formed along the longitudinal extension of the holding device, wherein a respective first receptacle is formed between two first webs which are adjacent in the circumferential direction.

[0012] It is thus possible to provide a compact and stable first holding unit.

[0013] Preferably, the second holding unit has a plurality of second webs which are arranged in the circumferential direction and are formed to extend in the longitudinal direction, wherein a corresponding second receiving portion is formed between two second webs adjacent to each other in the circumferential direction.

[0014] It is thereby possible to provide a robust and compact second holding unit.

[0015] Preferably, the respective first web of the first holding unit is arranged at least sectionally in the second receptacle of the second holding unit.

[0016] This makes it possible to achieve a reliable longitudinal guidance of the second holding unit on the first holding unit during the axial movement between the parking position and the operating position.

[0017] The locking element preferably has a plurality of locking webs which are arranged in the circumferential direction and are formed in a longitudinally extending manner, wherein a corresponding release receptacle is formed between two locking webs which are adjacent in the circumferential direction.

[0018] In the release position, the locking tabs are preferably arranged in the second receptacles of the second holding unit, respectively. In the locking position, the locking tabs preferably lock the second tabs of the second holding unit.

[0019] This makes it possible to clearly and precisely assign a locking position and a release position to the locking element.

[0020] According to one embodiment, the second holding unit has an inner receptacle in which a magnet is arranged, which is designed to fix the second holding unit on an output shaft associated with the holding device in the released position of the locking element and in the parking position of the second holding unit.

[0021] It is thus possible to easily achieve the fixing of the second holding unit in its parking position on the output shaft.

[0022] The first holding unit preferably has a rotationally fixed element on its side facing away from the second holding unit for being arranged in a rotationally fixed manner on a fastening interface of the handheld power tool.

[0023] This makes it possible to arrange the first holding unit in a rotationally fixed and secure manner on the fastening interface of the handheld power tool.

[0024] Preferably, the first holding unit has a holding section for detachable arrangement on an output shaft of the hand-held power tool.

[0025] It is thereby possible to fix the first holding unit and thus the holding device to the output shaft of the hand-held power tool in a stable and secure, but still releasable manner.

[0026] Preferably, a spring element is assigned to the second holding unit, which acts on the second holding unit both in the released position of the locking element and in the parking position into the operating position.

[0027] This makes it possible to support the manual displacement of the second holding unit from the parking position into the working position in a simple manner.

[0028] According to one embodiment, the first holding unit is equipped with a display element for visualizing the release position and / or the second holding unit is equipped with a display element for visualizing the locking position. Preferably, the display element for visualizing the locking position is equipped with a first tab of the first holding unit, and / or the display element for visualizing the release position is equipped with a second tab of the second holding unit.

[0029] The respective operating state of the holding device can thus be displayed safely and reliably to a user of the holding device. BRIEF DESCRIPTION OF THE DRAWINGS
