[0052] In order to avoid the side plate 7221 provided on the guide groove portion 722 , a spacing groove 735 is provided between the connecting portion 732 and the sliding block portion 731 , and the side plate of the guide groove portion 722 is inserted into the spacing groove 735 .

[0053] Reference Figure 8 , 11 As shown in FIG. 13 , the swing frame 740 includes a hook block 741 and a mounting block 742. The hook block 741 is provided with a groove 743. The groove 743 is open at the side and faces the side plate 130. The pin 750 is accommodated in the groove 743. The mounting block 742 is rotatably mounted on the rotating shaft 734 so that the mounting block 742 rotates around the rotating shaft 734.

[0054] Reference Fig.12 , 13As shown, specifically, when the drawer is closed, the pin 750 pushes the hook block 741 into the cabinet. As the pin 750 pushes, the swing frame 740 begins to swing toward the movable rail 300. During the swinging process, the pin 750 enters the groove 743, so that the pin 750 forms a temporary connection with the swing frame 740.

[0055] When the drawer is opened, the dial pin 750 pushes the hook block 741 toward the outside of the cabinet. When the maximum stroke of the buffer cylinder 710 is reached, the swing frame 740 begins to swing in the direction away from the movable rail 300 as the dial pin 750 is pushed, so that the dial pin 750 is disengaged from the groove 743, and the dial pin 750 is separated from the swing frame 740, so that the drawer can continue to be pulled out until the maximum stroke of the movable rail 300.

[0056] Reference Fig.11 As shown, in order to limit the swing angle of the swing frame 740 in the direction away from the movable rail 300, the swing frame 740 also includes a limit block 744, and a limit rib 723 cooperates with the limit block 744. The limit rib 723 is set on the short frame 720. After the limit block 744 collides with the limit rib 723, the swing frame 740 stops swinging.
