- the device becomes bulky transversely to the viewing direction and unmanageable for hard to reach places of use, in particular when approaching a rechargeable battery housing. Since the cross-section of the battery case is only slightly larger than that of the handle, the charge capacity of the battery and thus the performance of the device is limited.
- DE 42 02 348 C1 is an expansion head for hollow workpieces such as pipes, etc., known in which sector-shaped expansion jaws can be moved in the radial direction by an axially displaceable expanding mandrel. It is thus implemented an axial force on the sliding surfaces between expanding mandrel and expansion jaws in radial forces.
- drives for both pliers lever and motor hydraulic drives with thrust piston are known.
- the invention is based on the object of developing an approximately rod-shaped drive unit for tool heads to the effect that is characterized by a large volume for a larger battery or accumulator capacity and voltage, whereby drive power, duration of use and operating speed can be increased without departing from the scope of Hand device fall out and endanger ergonomic handling.

- a diametrical latch 21 For holding the tool head 19P is a diametrical latch 21 with a handle 21a.
- One of the hydraulic lines 22 is shown.
- the mechanism for the reversal of the hydraulic fluid between the pump and the reservoir or flow and return of the working piston 16 is located in the pump carrier 4. Such switching mechanisms are - in itself - state of the art.
- FIG. 3 shows more details of the hydraulic reservoir 12: This consists of a U-shaped container made of an elastomeric material with two lateral legs 12a and 12b, which enclose the pump gear 11 between them in the installed state.
- the spatial definition is done via a molded-on version 23, two metal frames 24 and 25 and four screws 26 on the pump carrier 4.
- Two hose connectors 12c and 12d are for filling, venting and for connection to the hydraulic circuit. The arrangement is space-saving and very flexible against volume fluctuations.

- the housing end is formed by a cap 27 a, which encloses the space for receiving the batteries 1 and can be unlocked by a push button 27 b.
- the main part of the housing 27 form two mirror-symmetrical housing halves 27c and 27d, which abut one another at an axis-parallel and diametrical parting line 27e.
- the housing halves 27c and 27d form a gripping part 28 which-apart from surface profiling 28a for increasing the grip-lies in a cylindrical surface.
- the handle part 28 ends in the direction of the tool head 19P in an annular bead 28b, and in front of this annular bead 28b a trigger button 30 is arranged for the start-up of the device.

Also the assemblies and components after the FIGS. 3 to 6 are also for the embodiment of the FIGS. 7 to 10 used. Up to the annular bead 28b, the components and the spatial form of the housing 27 also agree, so that the same advantageous operating characteristics result.

- the adapter 41 further has a coaxial bore 41 b, in which an expanding mandrel 42 is displaceable. This is, again releasably, bolted to the otherwise largely identical working piston 16 and serves for the radial displacement of the Expander jaws 39 (FIG. FIG. 8 ).
- This radial displacement is, for example, the preliminary stage of compression, namely by a pipe end being widened (expanded) so far that a non-widened pipe end can be inserted.
- FIGS. 1 to 7 and 8 to 10 shows that the invention provides a slim drive tool for tool heads, which is characterized by a larger volume for a larger battery capacity and higher battery voltage, which drive power, operating time and operating speed are increased, which in turn leads to larger volumes and weights for the drive elements , and that it nevertheless managed to maintain the handiness and safety.
