Meanwhile, the hanging and buckling block 65 on the guide rail is locked in a locking area 64 formed by the locking arm 63 and the hanging and buckling block 65.
As shown in fig. 6 and 7, when the user desires to open the guide rail, the drawer is pressed inward, and the drawer applies a pushing force F in an inward direction through the guide rail. The pushing force is transmitted to the first sliding block 6 through the hanging buckle block 65, and the first sliding block 6 pushes the rebound sliding block 2 to move inwards through the pressing of the reset hanging buckle 610 arranged at the outer end of the first sliding block and the reset hanging block 24 arranged at the bottom of the rebound sliding block 2.

Meanwhile, one supporting leg of the second torsion spring 68 installed in the first slider 6 extends into the movable track of the resistance arm at the tail of the driving arm 67, so that the inner end of the driving arm 67 deflects towards the direction of the first guide table, the inner end of the driving arm is used for pushing the second hook 32 to butt against the second hook, and when the guide rail is continuously closed, the rebound hanging block 3 is pushed to move inwards and rightwards through the first slider 6, and power for pushing the rebound hanging block 3 to deflect towards the direction of the locking block 4 is generated. When the first hook 31 slides to the innermost end on the side wall of the first guide table 33 in the main body 1, the first hook 31 is hung and buckled on the locking block 4 to play a role in locking the rebound slide block. When the first hook 31 is hung and buckled on the locking block 4, the main body of the first hook deflects to force the inner end of the driving arm to push and separate from the second hook 32, and the guide rail is driven by the reset buffer device inside the guide rail to realize automatic reset.
