The invention relates to an electric portable power tool for a discoid rotating implement (18). The power tool comprises a power tool housing (11), out of which a drive spindle (12) for the implement (18) projects and on which a hollow cylindrical chuck collar (15) is formed that is coaxial to the drive spindle (12). The power tool also comprises a protective cover (20), which is detachably mounted on the power tool housing (11), provided for at least partially covering the implement (18), and which can be placed on and fixed to the chuck collar (15) by means of a clamp (23) having a tightening element (24). In order to place the protective cover (20) in desired positions of rotation relative to the power tool housing (11) without the use of an auxiliary tool and to secure the protective cover (20) in any set position of rotation, the clamp (23) is held on the chuck collar (15) in a manner that enables it to rotate, and a manually releasable locking is formed between the clamp (23) and the chuck collar (15).

The invention relates to a protective device (33) for a hand machine tool, particularly for a sanding hand machine tool, comprising a protective guard (40). Said protective guard is provided for at least partially enclosing a rotating tool in a radial direction. The protective device is also equipped with a guiding means for guiding the protective guard (40) along a workpiece (30) and with a fixing device for fixing the protective guard (40) to the hand machine tool. According to the invention, the guiding means is connected to the protective guard (40) in a rotationally fixed manner, and the protective guard (40) is mounted in a manner that enables it to move in relation to the fixing device.
摘要:
Eine Handwerkzeugmaschine (1) weist einen zu einer Antriebswelle (4) koaxialen Spindelhals (5) auf, auf den der Schutzhaubenkragen (7) einer Schutzhaube (6) aufgesteckt werden kann. Im verbundenen Zustand ist die Schutzhaube (6) verdrehbar und verrastet in aufeinander folgenden Winkelstellungen. Der Spindelhals (5) weist eine umfangsseitige Führungsnut (10) auf, die durch mindestens eine axiale Durchtrittsausnehmung (11) zugänglich ist. Am Schutzhaubenkragen (7) ist mindestens ein durch die Durchtrittsausnehmung (11) passendes und beim Verdrehen der Schutzhaube (6) in der Führungsnut (10) geführtes Führungsglied (12) angeordnet. Am Spindelhals (5) sitzen hintereinander eine feststehende Rastscheibe (13) und ein verdrehbarer, beim Verdrehen in aufeinander folgenden Winkelstellungen mit der Rastscheibe (13) verrastender Rastring (14). Mindestens ein am Schutzhaubenkragen (7) angeordnetes Mitnahmeglied (15) gelangt beim Aufstecken in Drehmitnahmeeingriff mit dem Rastring (14).
