The positioning device 6 consists of a positioning member 61 and an actuating member 62 pivot-connected thereto. The positioning member 61 provides with at least one engaging end 614 while the actuating member 62 providing with at least one bent guiding edge 622 and a push button 623. The engaging end 614 is adapted to engage with an oblique protrusion 31 of the outer slide track 3 for positioning the intermediate slide track 2. A return movement of the inner slide track 1 can actuate the bent guiding edge 622 for automatically unlocking the engagement of the intermediate slide track 2 with the outer slide track 3.
