The tool extender 100 includes a sleeve 104 defining a receptacle and an extension member 102 having a first end 110 and a second end 106. The second end defines a cavity 114 and is slidable within the receptacle of the sleeve between fully extended and fully retracted positions. The extender also includes a bias member 116 seated in the receptacle and an end disposed in the cavity for biasing the extension member outwardly from the sleeve to the fully extended position. The bias member may be a coil spring or a tapered spring. An alternative adjustable tool extender may have an extension member with an intermediate portion having a cross-sectional area less than that of either of its first and second ends. |
