发明名称 Hand-guided electric tool comprising a guard
摘要 In a hand-guided electrical tool 3 with a housing 2 that has a receiving collar 20 embodied on it and with a guard hood 1 that can be attached to the receiving collar 20 and has a clamping strap 16, which can move freely around the receiving collar 20 in a first position and rests snugly against the receiving collar 20 in a second position, a secure connection between the guard hood 1 and the housing 2 is achieved by virtue of the fact that the receiving collar 20 has at least one protrusion 21, which protrudes beyond the second area in the radial direction away from the spindle axle 5, and between the protrusion 21 and the housing 2, there is a distance h, which approximately corresponds to the width b of the clamping strap 16, and by virtue of the fact that that the clamping strap 16 has at least one indentation 12 so that the first diameter d1 of the opening 10 of the clamping strap 16 in the vicinity of the indentation 12 is greater than the second diameter d2 in the remaining region, wherein the first diameter d1 is of such a size that the clamping strap 16 can be moved over the protrusion 21 and the second diameter d2 is of such a size that the clamping strap 16 cannot be moved over the protrusion 21.
