ABSTRACT:
The invention relates to an extension arm (6) that is arranged on a carrier (4) in such a way that it can pivot about the axis (18) thereof by means of a steering rod (20), and can be blocked in the pivoted position. Said steering rod (20) is arranged on a sleeve (44) that can be pivoted about the extension arm (6), can engage with the extension arm in different rotational angle positions, and can be directly or indirectly blocked on the carrier. According to the invention, a first coupling part (40) fixed to the extension arm (6) co-operates with a second coupling part (42) arranged on the sleeve (44) and acting in the axial direction. Furthermore, the steering rod (20) comprises a supporting element (56) that co-operates with a counterpart (58) arranged on the extension arm (6), in order to displace the second coupling part (42) in the axial direction by means of the steering rod (20). In this way, the extension arm can be pivoted and blocked in a simple manner with one hand.
