The boss portion 203 and the second boss portion 204 extend symmetrically on the upper and lower sides of the opening groove 201 to form the third boss portion 202 . As shown in Figure 2 and Figure 3, the spring clip 4 is connected by a straight side 402 and two symmetrical hypotenuses 403 to form a trapezoid, and the ends of the two hypotenuses 403 are bent inwardly to form a flanging 404. The side 403 is also provided with a second slot 401 for clamping the third boss portion 202 .

As shown in FIGS. 2 and 3 , on one side of the second locking element 5 , a locking boss 6 for abutting against the spring clip 4 is also provided on the outer rail 3 .

The working process of the first locking mechanism is as follows:

As shown in Figure 3, the linear sliding of the middle rail 2 relative to the outer rail 3 is realized through the middle rail ball cage (not shown in Figure 3), since the spring clip 4 is installed in the open groove 201 on the middle rail 2, Therefore, the spring clip 4 moves with the middle rail 2 until the straight edge 402 of the spring clip abuts against the locking boss 6. At this time, the middle rail 2 cannot slide relative to the outer rail 1, and the flanging of the spring clip 4 simultaneously 404 extends into the second opening 102 of the second locking element 5, and at the same time, the end surface of the flange 404 abuts against the concave surfaces 205 at both ends of the first boss portion 203 on the upper opening groove 201 of the middle rail 2, realizing that the middle rail 2 is opposite to each other. Due to the locking of the outer rail 3, the sliding movement of the inner rail 1 relative to the middle rail 2 is unlocked at the same time.

As shown in Figure 1, when the inner rail 1 needs to extend into the inner rail 1, the second connecting part 101 of the first locking element 5' moves to the flange 404 of the spring clamp 4, and the second connecting portion 101 moves toward the flange 404 of the spring clip 4 during the continuous movement. The two hypotenuses of the connecting portion 101 are in contact with the flange 404 and the casting expands the opening distance between the two flanges 404 of the spring clip 4, so that one flange 404 of the spring clip 404 stretches out from the second side of the second locking element 5. Opening 102, thereby completing the unlocking between the middle rail 2 and the outer rail 3, and at the same time, a flange 404 of the spring clip 404 enters the second opening 102 along the engaging boss 106 of the first locking element 1, thereby The locking of the inner rail 1 and the middle rail 2 is realized, so that the inner rail 1 cannot be linearly displaced relative to the middle rail 2 .
