摘要:
The invention to a battery-driven screwdriver (10) comprising a housing (12, 18) having a grip (14), more particularly with a permanently built-in rechargeable battery (40), in addition to charge contact tongues (37) for charging the rechargeable battery (40). Said battery-driven screwdriver is particularly characterized in that it is compact and light and in that counter contacts (34) are provided instead of a fixed box-like standard on/off switch on the machine side, a contact plate (32) being assigned to said counter contacts. The contact plate can be moved by means of an on/off button (26) thereby coupling it to the counter contacts (34) and enabling it to be easily released when said button is let loose.

The invention relates to a device comprising at least one suppressor (10, 12) for reducing interference, especially in the high-frequency range of an electric machine (18), and also comprising at least one connection element (14, 16) for connection to a pole shoe of the electric machine (18). According to the invention, the suppressor (10, 12) is secured in a receiving area (20, 22) of the connection element (14, 16) which is provided with a plug-in element (24, 26) for connection to the pole shoe and is combined therewith to form a module (28, 30, 32, 34).
摘要:
The invention relates to a housing device for a machine tool (10) with a tool holder (17), in particular, on a hand-held machine tool, for housing exchangeable tools. According to the invention, the tool holder (17) forms a detachable sliding seat (18) with a drive tube (16). The invention further relates to a tool holder (17).
摘要:
The invention relates to a battery-driven screwdriver (12, 18) comprising a particularly pistol-like, angled grip (14) having preferably a permanently built-in rechargeable battery (40), in addition to charge contact tongues (37) for charging the rechargeable battery (40) and an output spindle (20). Said battery-driven screwdriver is always ready to use and can be rapidly accessed in that it has a lithium-ions (Li-ion) cell as rechargeable battery (40) and in that it can be stored for an unlimited time in a charge cradle (22), particularly when it is not being used, wherein the charge mode is automatically set and the battery-driven screwdriver (40) is positioned inclined in the charge cradle (22) with respect to its output spindle (20), more particularly at an angle of approximately 30 - 45 ° with respect to a vertical line, wherein the end of the output spindle (20) points downward.
摘要:
An interchangeable tool and tool holder are disclosed for drilling machines, in particular drilling hammers. Longitudinal ridges on the cross-section (1) of the core of the insertable tool shank (11) axially guide the tool, transmit rotary forces and lock the tool in the tool-receiving cavity of the tool holder.
摘要:
The invention concerns a tool holder (10) for inserted tools in drill and/or hammer-driven machines, having means for rotating and axially locking a tool spindle insertable into a tool holder (11) of the machine, where the tool holder is fitted with several radially inward-projecting axial ridges (13) for rotation and at least one radially lockable clamp on the tool holder (10) for locking purposes. In order to accept tool spindles of two groove spindle systems with different outside diameters, on the holder drilling (12) there are two opposite, radially inwardly directed axial ridges (13) which are radially guided and especially spring-loaded to be released outwards, where the axial ridges (13) engage in corresponding grooves (20) in the tool spindle (19) so as to rotate the tool.
