A telescopic rod (10) for a hand tool, comprising an inner pipe (20), an outer pipe (30) nested on the inner pipe, and a positioning assembly (40) provided on the outer pipe. The positioning assembly has a sliding block (42), a positioning pin (46) and an operating knob (43). The sliding block is slidably provided on the outer pipe, and has a push top portion (421) and a guide slot (424) provided in the push top portion. The positioning pin can axially move and pass through the guide slot of the sliding block and abuts the push top portion of the sliding block. The operating knob is connected to the sliding block through a connecting piece (44) to drive the sliding block to move. When the sliding block moves axially along the outer pipe by the pulling of the operating knob, the push top portion of the sliding block will push the positioning pin to separate the bottom of the positioning pin from a positioning hole (22) of the inner pipe, that is, a relative position between the inner and outer pipes is adjustable so as to achieve the purpose of adjusting the length.
