Abstract
A hand-guided working tool has a telescopic rod with a first and a second end. A drive motor is connected to the first end of the telescopic rod. A working tool, connected to the second end of the telescopic rod, is driven by the drive motor. The telescopic rod includes an outer tube and an inner tube inserted with an inner end into the outer tube and displacable in the longitudinal direction of the telescopic rod. A first clamping member is connected to the first end of the outer tube for fixing the axial position of the inner tube. The inner tube has an outer mantle surface and the outer tube has an inner circumferential surface. The outer mantle surface is spaced at a radial distance from the inner circumferential surface. A first cylindrical bearing body is supported on the inner end of the inner tube. The first bearing body is displacably supported in the outer tube. The first clamping member has an inner circumferential guide surface matching the outer mantle surface of the inner tube such that the inner tube is secured coaxially relative to the outer tube by the first clamping member and the first bearing body.
