摘要:
An injection-molded plastic handle for tools, particularly screwdrivers, having zones of plastic of different hardness, the harder plastic being nondeformable under the forces which occur as a result of the actuating load while the softer plastic permits slight elastic deformations, and having a centrally located receiving hollow space (5) for the tang of a tool blade (2), and, in order to obtain a development which is of optimized grippability and more advantageous in use, the central hollow space is located in a center part (6) having a profiled cover surface (11) around which a cover is injected, the depressions (8) resulting from the profiling of the cover surface (11) being filled with a softer plastic until obtaining an approximately circular cross-sectional shape.
摘要:
A tool set having a screwdriver handle with a chuck for insertion and latched mounting of screwing-tool inserts provided with standard polygonal shank segments, and having screwing-tool inserts, which are insertable into the chuck and are provided with the standard polygonal shank segments, in particular bits, nuts or ratchets and extensions for drive of the latter, comprising a supplementary tool which has a plier head (2) and a plier-handle projection (4) which is disposed immediately behind a knuckle joint (5) and is in form of the standard shank segment of the screwing-tool inserts, the screwdriver handle (9) latches to the plier-handle projection by its chuck (10), forming one of two plier arms and a blade extension (11) which likewise has a chuck (10), forming other of the two plier arms.
摘要:
A chuck for receiving tools (1) that are operated by rotating around the axis thereof, particularly screwdriver bits, and having an insertion section (3) which is provided with a receiving cavity (2) having a non-circular cross-sectional area (3). The tool can be locked in the cavity (2) by a holding element (4) which is assigned to the cavity wall in order to prevent the tool from being withdrawn from the cavity (2). The holding element (4) can be deactivated by displacing an actuating member in a form of an actuating sleeve (5). The tool (1) rests backwards against the cavity (2). The tool (1) can be displaced from the resting position in the direction of the opening of the cavity (2) by actuating the actuating sleeve (5). In order to facilitate removal of the bit, the chuck also comprises components (15, 16, 17) for releasing the face (1) of the bit, and a magnet (9) which retains the bit in the cavity from the resting position.

摘要:
A invention relates to a chuck having a shank which provides two shank sections (5, 6), forms a clamping section (1) at one end for clamping in place in a drive member and forms a tool mounting (2) at the other end for mounting a tool, in particular a screwdriver bit (18), having an elastic element between the clamping-side shank section (6) and the tool-mounting-side shank section (5) for permitting a stop-limited twisting capability of the clamping section relative to the tool mounting (2). To achieve a narrow type of construction, provision is made for the elastic element to be formed as a bending spring which is bendable transversely to the axis of the chuck and connects the two shank sections to one another.
摘要:
A storage device including a storage container that can be brought from a storage position in which a tool stored therein cannot be removed, to a removal position, in which the tool stored therein can be removed, with an indication element indicating the tool, the indication element being distinct from the storage container but firmly attached to the storage container and visible in the storage position. According to the invention, an indication element is provided that can be attached to the storage container in simple manner and is not only visible but also palpable, wherein the indication element is a flattened relief of the tool.
摘要:
A screwing tool, particularly a screwdriver (1) or screwdriver bit, for polygonal socket screws (8), having flank sections (12) which are convex in circumferential direction; in order to optimize the transmission of force it is proposed that the flank sections (12, 12') be interrupted in the central region of each flank (11) by a non-convexly extending intermediate section (13/13').
摘要:
A screwdriving tool includes a gear head and a drive arm. The gear head forms a gear housing, in which a free wheel or ratchet gear having an output rotational axis is arranged. A front side of the gear head includes an output coupling, in the shape of a polygon. The drive arm can be pivoted about a pivot axis, which is substantially transverse to the output rotational axis, from a quick-action screwdriver position, in which the drive arm is in the output rotational axis, into a power-action screwdriver position, in which the drive arm extends substantially transversely to the output rotational axis and can be fixed in both pivot positions by detents. The detents can be moved from a detent position into a release position by means of an actuating member associated with the drive arm.
摘要:
The invention relates to a method and to a production line for carrying out the method for producing internal geared workpieces, particularly sliding sleeves. The invention discloses a method, which is advantageous with regard to production engineering, for producing a sliding sleeve and a production line for carrying out the method. With regard to the method, the invention provides that the teeth of the workpiece are made on the finished tooth contour by hob peeling, and the tooth flanks and/or the tooth faces are subsequently machined with a cutting edge tool, and with regard to the production line, the invention provides a shaping device for making teeth having a crude tooth contour, a hob peeling device, which is located downstream from the shaping device and which serves to finish the finished tooth contours of the teeth, and a tooth flank and/or tooth face machining device located downstream from a hob peeling device.
