摘要:
An electric hand power tool has an on/off switch, an elongated switching key having a front end and a rear end and actuating the switch, a blocking lever carried by and projecting from the switching key to prevent or to allow turning on of the latter, the switching key being supported turnably, the switching key having a convex curvature starting substantially centrally and extending toward the rear end, the switching key carrying the blocking lever near the rear end, the blocking lever having an upper edge located under a tangent between the convex curvature and the rear end of the switching key.
摘要:
The invention relates to a tool receiving device for a machine tool (14), comprising an at least essentially disk-shaped hub (42), particularly for a hand-guided angle grinder (32) or a hand-held circular saw. Said tool receiving device also comprises a drive shaft (16) and a receiving device (12) comprising at least one catching element (20) which can be displaceably mounted against a spring element (18) in order to fix the machine tool in a positive fit in the direction of the periphery (50, 52). According to the invention, the drive shaft (16) comprises at least one shaped positive fit non chip-removing element (100) which is connected in a positive fit in the direction of the periphery (50, 52) to means for the transmission of drive torque in the receiving device (12).
摘要:
The present invention is directed to an insertion tool (12) for an angle grinder (2) that has a hub (16) with at least a first fastening means for fastening the hub (16) to a driving device (22) of the angle grinder (2). It is provided that the first fastening means is located on a partial circle (54) with a radius (56) between 12 mm and 25 mm.

摘要:
A tool-handling device for an insert tool(14) equipped with an at least essentially disk-shaped hub (42), in particular for a hand guided angle grinder (32) or a hand-guided circular saw, having a drive shaft (16) and a drive device (12) equipped with at least one locking element(20) that is supported so that it is able to move in relation to a spring element (18) in order to fix the insert tool (14) in a form-locked manner in the circumference direction (50, 52).The drive shaft (16) has at least one form-locking element (100) formed onto it in a non-cutting manner in order to connect it in a form-locked manner in the circumference direction (50, 52) to a drive torque-transmitting mechanism of the drive device (12).

摘要:
A protective hood (1) for a right-angle grinder having a tightening device, which has a tightening band (4) firmly connected to the protective hood (1) for a right-angle grinder, the two ends (5, 6) of the tightening band being embodied as a first and second eyelet (7, 8), so that they form a first and second abutment (9, 10) and can be connected to one another under tension by means of at least two tightening elements, the first tightening element being a tightening lever (2), which with its first end (15) can be supported in the first eyelet (7) pivotably about a first axis (9a) and which can be brought into a first position in which the tightening device is not tightened, and into a second position in which the tightening device is tightened, becomes capable of being produced at less expense with still high quality by providing that the second tightening element is a spring (3), which can be connected movably to the tightening lever (2), the spring (3) being pivotably supported about a second axis (11) in the tightening lever (2) that does not coincide with but is parallel to the first axis (9a), and the spring (3) can be connected to the second eyelet (8) of the second end (6) of the tightening band (4), and the spring (3), on its end that can be connected to the second eyelet (8), has a straight region that is embodied as parallel to the second abutment (10).
摘要:
A power tool (10), in particular an angle grinder, having a housing (12) that receives an electric motor (21) and a gear (26), the motor (21) having a rotor (210) which is guided in rotor bearings (2100) and on one hand carries a collector (2102), which collector can be put into contact with a voltage source via carbon brushes (23) supported in brush plates, is made sturdier and easier to install in that the housing (12) comprises two longitudinally split housing shells (120, 121), and that the brush plates are part of a bearing bridge (24) that carries both the rotor bearing (2100) and the carbon brushes (23), and the bearing bridge (24), in the guide region of the carbon brushes (23), comprises plastic.
