A handle is rotatably secured to a housing with a pivot shaft for allowing the handle to be rotated relative to the housing between a working and a storing position. A spring may bias the handle to rotate relative to the housing from the working position to the storing position. A damping device may be used to damp the rotational movement of the handle relative to the housing and includes a gear provided on the pivot shaft, a tube rotatably received in the housing and having a pinion engaged with the gear for preventing the handle from sprung back to the storing position.
