The guiding surface 44 of the second end 42 (refer to the fifteenth figure), to drive the positioning block 4 to move downward along the sliding slot 21 of the middle sliding rail 2 (refer to the sixteenth figure), and the first end 41 utilizes the guiding angle 45, in order to facilitate the disengagement from the first rib 14 of the outer slide rail 1 , the second end end 42 passes through the first unlocking portion 32 to block the first stop portion 34 and the second block of the inner slide rail 3 Between the portions 35 (see FIG. 17), and having a front and rear movable clearance and an up and down displacement stroke, the inclined surface of the second unlocking portion 33 is pushed against the guiding surface 44 of the second end 42 of the positioning block 4 to drive the positioning block. 4 moving downward along the sliding slot 21 of the middle rail 2, so that the positioning block 4 is pushed upward by the elastic force of the return spring 5 (refer to the third figure) against the second unlocking portion 33 and the second blocking portion 35, and then positioning the block 4, by using the guiding surface 44 to push up against the inclined surface of the second unlocking portion 33 to generate displacement, so that the positioning block 4 is positioned upwardly to the first blocking portion 34 and the second unlocking portion 33 (refer to the second figure), so that the middle sliding rail 2 with inner slide 3 Positioning, and allowing the positioning block 4 and the second blocking portion 35 to be relatively displaced, and the second unlocking portion 33 drives the positioning block 4 to move up and down to release the locking state of the outer sliding rail 1 and the middle sliding rail 2, The middle slide rail 2 and the inner slide rail 3 can be held in the outer slide rail 1 in synchronization with the displacement. Therefore, the combination of the slide rail 1, the middle slide rail 2 and the inner slide rail 3 of the present invention can smoothly slide and fold and pull out in sequence, and can improve structural strength and durability, and is easier to manufacture and assemble.
