Definitions
- the present invention relates to a screwdriver unit for screwdriver bits with a fastening area and a functional area, so-called bits.
- Screwdriver bits are usually tubular or rod-shaped, the tube or rod having an attachment area and a functional area.
- the fastening area is usually angular, preferably in the form of a hexagon.
- For the functional area all designs of blades and the like known from screwdriver tools come into question, for example for slotted screws, Phillips screws, hexagon socket screws, special screws and the like.
- the screwdriver bits are inserted with their fastening area from the outside into an appropriately designed receptacle for a handle, a machine screwdriver or an adapter designed to accommodate the screwdriver bit, and are thus secured in the receptacle so that they cannot rotate. This means that several different screwdriver tools can be replaced with just one hand movement or only one machine screwdriver driven electrically or with compressed air by using different screwdriver bits.
- handles which provide a closable container in the handle area, in which several screwdriver bits can be stored.
- the screwdriver bits are loosely inserted into the container, and to use a screwdriver bit, all screwdriver bits usually have to be removed from the container to select it. With this extremely impractical handling there is also the possibility that screwdriver bits are lost and otherwise damaged.
- the present invention is based on the object of providing a screwdriver unit for screwdriver inserts which enables improved, possibly automated handling of the screwdriver inserts, the range of uses of which can be expanded, and which can also be inexpensively manufactured using simple means.

- a cover which can be fastened to the container or to the base part and which is preferably hemispherical.
- the at least one opening and the receptacle of the cover part are formed coaxially with one another. This ensures that a screwdriver insert can be easily positioned in the receptacle from inside the container through the at least one opening in the cover part.
- the positioning can advantageously be carried out with only one hand holding the screwdriver unit, for example by pivoting or tilting the screwdriver unit, so that the other hand of the user remains free and can be held somewhere, for example, with the free hand, especially when screwing in difficult Positions, for example when fastening facade panels and the like.
- the receptacle is tubular and preferably has a hexagonal cross section on the inside. This ensures that standardized screwdriver bits can be used in the screwdriver unit.
- the receptacle is advantageously designed to taper in the direction out of the container. As a result, the screwdriver insert can be automatically clamped with its fastening area when it is positioned in the receptacle and thus fastened.
- the receptacle has an opening designed with the cross section of the functional area. This ensures that the screwdriver bit cannot fall out of the receptacle in the direction out of the container.
- the cover part can be detachably attached to the container. This creates the possibility of replacing the insert which can be arranged in the container or the screwdriver inserts which can be stored therein, for example in the event of damage and the like.
- the insert has at least one storage space for a screwdriver insert.
- the at least one storage space is advantageously cylindrical and runs essentially parallel to the screw axis.
- the storage space advantageously has an opening corresponding to the opening of the cover part, which opening is designed to be slightly larger than the cross section of the fastening area of the screwdriver insert.
- the insert is rotatably mounted in the container. This creates the opportunity to select different screwdriver bits housed in the insert for use by rotating the insert.
- the insert advantageously has a marking or the like which is visible from the outside and by means of which the user can recognize which screwdriver insert is available for use.
- the at least one storage space is arranged eccentrically in use.
- the opening of the at least one storage space of the insert can advantageously be positioned coaxially with the opening in the cover part.
- the screwdriver insert accommodated in the at least one storage space can be positioned below the at least one opening and the receptacle in the cover part, that is to say aligned coaxially with the screw axis.
- the insert has an adjusting device for positioning the screwdriver bits.
- the adjusting device is disc-shaped, preferably as a circular disc.
- the adjusting device can be actuated from outside the container.
- the adjusting device is at least partially protruding through the container.
- the adjusting device is formed on its outer edge surface with elevations and / or depressions which enable the insert to be rotated more easily.
- the insert has a releasable locking device, which advantageously is formed by radial recesses in the insert, in which an elastically mounted locking pin engages to fix the insert in the container.
- Fig. 1 is a partially sectioned illustration of a screwdriver unit according to the invention.
- FIG. 2 shows a section along the section line II-II according to FIG. 1.
- FIG. 1 and 2 show a screwdriver unit 1, consisting of a container 6 which delimits a volume space 5 with a cylinder 2, a circular base part 3 and a likewise circular cover part 4.
