发明名称 EXTENSION HANDLE APPARATUS
摘要 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.
