A tool extension bar includes a rod including first and second ends. The second end is adapted to connect to and be driven by a power tool. A positioning bore is formed at the rod to receive a positioning assembly. A sleeve is slidably mounted around the rod and includes an end adapted for connecting to a tool member. A coupling hole extends through the sleeve. A radial hole extends from an outer periphery of the sleeve through an inner periphery of the coupling hole. The positioning assembly constantly abuts against the inner periphery of the coupling hole. An engaging member is movably received in the radial hole and is moveably engaged in the recess of the rod. The engaging member releasably engages the sleeve with the rod. |
