Claim Text:
1. A telescopic rod comprising: a small-diameter rod segment; a large-diameter rod segment which extends in a lengthwise direction, and which is telescopically joinable to said small-diameter rod segment, said large-diameter rod segment including a uniform-dimension main region, a marginal region, and a dimension reducible region which is disposed between said uniform-dimension main region and said marginal region, and which is formed with an elongated gap extending in the lengthwise direction to terminate at proximate and distal end zones relative to said marginal region, said dimension reducible region being further formed with proximate and distal transverse slots disposed opposite to each other in the lengthwise direction, each of said proximate and distal transverse slots extending in a transverse direction relative to the lengthwise direction, and being in spatial communication with a corresponding one of said proximate and distal end zones of said elongated gap, thereby forming left and right grip areas that are spaced apart from each other by said elongated gap; and a clamping unit including a flexible collar which is disposed to surround said dimension reducible region such that when said small-diameter rod segment is joined to said large-diameter rod segment, said clamping unit is displaceable between an untightened state, where said small-diameter rod segment is telescopically slidable relative to said large-diameter rod segment, and a tightened state, where said dimension reducible region of said large-diameter rod segment is squeezed by said flexible collar such that said left and right grip areas tightly and evenly grip said small-diameter rod segment, thereby preventing movement of said small-diameter rod segment relative to said large-diameter rod segment, wherein each of said proximate and distal transverse slots has left and right slot portions which extend away from each other from the corresponding one of said proximate and distal end zones of said elongated gap.
