A tool reach extension pole includes an inner slider tube 12 telescopically received in an open end of an outer handle tube 10 for relative longitudinal shifting movement. The slider tube 12 includes a radially extending hole within which a locking pin 48 is received, and the pin extends through a slot 22 formed in the handle tube 10. The pin 48 includes a head 50 having a width greater than that of the slot 22, and is received in a circumferentially extending eccentric slot of a locking grip 52 that is rotatable and longitudinally shiftable relative to the handle tube 10. By providing this construction, longitudinal shifting movement of the locking grip 52 relative to the handle tube 10 is transmitted to the slider tube 12 by the locking pin 48, and rotational movement of the locking grip relative to the handle tube shifts the locking pin within the slider tube hole between a locked position in which the handle tube 10 and slider tube 12 are locked against relative longitudinal shifting movement, and an unlocked position in which the handle tube and slider tube are longitudinally shiftable relative to one another. |
