The mounting seat 20 is internally provided with a mounting groove 201, and the rebound device 21, the rebound deflector 22 and the pressing clamping point groove 24 are all arranged in the mounting groove 201.

In detail, one end of the rebound device 21 is provided with a lever connecting piece 25, the middle part of the rebound lever 22 is provided with a positioning column 221, and the lever connecting piece 25 is provided with a shaft hole 251 corresponding to the positioning column 221 for setting connection of the rebound lever 22. One end of the driving lever connecting piece 25 is provided with a hook part 23, one side of the driving lever connecting piece 25 on the rebound driving lever 22 is provided with a driving lever rebound post 26, and the rebound device 21 is a spring. Referring to fig. 2 and 6, the buffer mechanism 3 is disposed on one side of the sliding rail 12, the buffer mechanism 3 includes a buffer 31 and a steering rail 32, the buffer 31 is connected to a switch claw 33, and the switch claw 33 is provided with a groove 331. The buffer 31 and the switch claw 33 are connected through a switch claw connector 34, the buffer 31 may be a spring, the other end of the buffer 31 is provided with a buffer shift lever 35, a clamping groove 351 for limiting the buffer shift lever is provided behind the steering track 32, and one end of the fixed track 11 is further provided with a fixed buffer shift lever shift post 113.

The principle of operation of this embodiment is as follows: referring to fig. 5, 6 and 7, in this embodiment, the carried object 4 may be a drawer or a wardrobe (as shown in fig. 14), the carried object 4 is fixed on one side of the sliding rail 12, the carried object 4 is in a closed state (i.e. the drawer is closed), the rebound device 21 of the rebound mechanism 2 is in a stretched state to store elastic force, and the hook portion 23 at one end of the lever connecting member 25 is locked in the locking point 243 of the pressing locking point groove 24. When the carried object 4 is pressed by an external force (i.e. when the drawer is pressed, the drawer is to be ejected), the carried object 4 will drive the sliding rail 12 to move, and along with the movement of the sliding rail 12, the push-button lever 122 is started to push the lever rebound post 26 of the lever connector 25, and then drives the hook 23 at one end of the lever connector 25 to disengage from the catch 243 along the escape ramp 242 of the push catch slot 24, as shown in fig. 8, so that the spring force of the spring back 21 is released, and the carried object 4 is ejected. Meanwhile, when the load 4 is pressed by an external force, as shown in fig. 12 and 13, the driving pawl 112 of the fixed rail 11 is pressed inward, so that the pawl 33 of the buffer mechanism 3 is separated from the driving pawl 112, i.e. the driving pawl 112 is separated from the groove 331 of the pawl 33. Referring to fig. 9 and 10, as the sliding rail 12 moves gradually, the driving of the sliding rail 12 presses the driving lever post 121 to swing the resilient driving lever 22, so as to open the drawer smoothly, and then the resilient driving lever 22 swings to touch the driving lever post 26, as shown in fig. 11, the resilient driving lever 22 is resiliently retracted due to the elastic force of the driving lever post 26, so as to achieve the effect of automatic alignment. At the same time, the positive opening and closing claw shifting column 111 drives the opening and closing claw 33 to slide forward to reach the positioning, and then the opening and closing claw 33 swings inwards along the steering track 32, so that the opening and closing claw 33 is fixed to be beneficial to opening the buffering effect when the drawer is closed.

Referring to fig. 10 and 11, when the drawer is closed, the driving pressing lever pulling post 121 drives the rebound lever 22 forward until the hook portion 23 is clamped, so that the hook portion 23 faces the guiding ramp 241 of the pressing clamping point groove 24, and at the same time, the carried object 4 drives the sliding rail 12 to move, when the buffering lever 35 is driven to the fixed buffering lever pulling post 113 along with the movement of the sliding rail 12, the buffering mechanism 3 continuously moves to the rear clamping groove 351 so that the buffering lever 35 is fixed at the rear clamping groove 351, the buffering function is started by the fixed buffering lever pulling post 113, and when the switching claw 33 is pulled to the switching claw pulling post 112, the switching claw connector 34 (marked in fig. 6) is driven to buffer backward by the switching claw 33 to complete the buffering action. At the same time, the actuation-press lever paddle 122 (shown in fig. 7) snaps onto the lever jack 26.
