ABSTRACT:
A sectional adjustable socket tool handle, which controls the movement of an axial rod along the axial direction of an external pipe. The tool includes a plurality of grooves, a coupler for engaging the plurality of grooves, such that a latch member on the external pipe is latched into the groove under normal conditions, and the coupler can move between a first position and a second position along the axial direction of the external pipe. When the coupler moves to the first position, the coupler will press against the latch member to prevent the axial rod from moving. When the coupler moves to the second position, the coupler will release the latch member.
