The second elastic member 44 is disposed between the rear side of the drawer 20 and the blocking end 412 of the pivoting member 41, and the second elastic member 44 stretches as the pivoting member 41 pivots relative to the drawer 20. In this embodiment, the second elastic member 44 is a tension spring, and the positioning device 40 can have two second elastic members 44 respectively disposed between the rear side of the drawer 20 and the stop end 412 of the pivoting member 41 and Adjacent to both sides of the drawer 20, respectively.

4 to 7 are schematic diagrams of using the drawer slide assembly shown in FIGS. 1 and 2. Please refer to FIG. 4. The positioning device 40 shown in FIG. 4 is located at the first stop position, the stop end 412 of the pivoting member 41 is stopped at the first stop surface 421 of the first stopper 42, and the first elastic member 30 Both the second elastic member 44 and the second elastic member 44 are in a natural state, that is, an unstretched state. At this time, the drawer 20 cannot slide relative to the guide rail portion 12, that is, the drawer 20 is kept in a closed state.

Please continue to refer to FIG. 5, the user can apply force to the operation end 411 of the pivoting member 41 along a force applying direction FD, and the pivoting member 41 pivots relative to the drawer 20 so that the stop end 412 of the pivoting member 41 is released from the first stop The first blocking surface 421 of 42 and the second elastic member 44 are stretched by being driven by the pivoting member 41.

Please continue to refer to FIG. 6, when the stop end 412 of the pivot 41 is separated from the first stop surface 421 of the first stop 42, the drawer 20 can slide from the rear end 121 of the guide rail portion 12 to the front end 122 along the sliding direction SD and The first guiding surface 422 of the first stopper 42 is passed, and the first elastic member 30 is stretched by the driving portion 21 of the drawer 20.

Please continue to refer to FIG. 7, when the drawer 20 slides to the front end 122 of the guide rail portion 12 along the sliding direction SD, the user can apply force to the operation end 411 of the pivoting member 41, and the pivoting member 41 pivots relative to the drawer 20 to stop the end 412 passes over the second guide surface 432 of the second stopper 43 and stops at the second stop surface 431. At this time, the positioning device 40 is located at the second blocking position, so that the drawer 20 is maintained in the opened state, and the elastic state of the first elastic member 30 does not change from the opened state to the closed state.

Therefore, it can be understood that when the positioning device 40 is located at the second stop position, the user can apply the force to the operation end 411 of the pivoting member 41 again, and the pivoting member 41 pivots relative to the drawer 20, so that the stopper end 412 is released from the second stop The stop surface 431, the drawer 20 is pulled by the elastic restoring force of the first elastic member 30 and automatically slides from the front end 122 of the guide rail portion 12 to the rear end 121, and is guided by the first guide surface 422 to make the pivot 41 The blocking end 412 is blocked by the first blocking surface 421 of the first block 42 again, so that the positioning device 40 is changed to the first blocking position.

To sum up, the drawer slide assembly of this embodiment uses the elastic restoring force of the first elastic member 30 to pull the drawer 20, so that the drawer 20 is automatically slid from the front end 122 to the rear end 121 of the guide rail portion 12. In addition, by providing the first elastic member 30 and the positioning device 40, the drawer 20 can be selectively opened or closed relative to the guide rail portion 12, and is positioned between the first stop position and the second stop position via the positioning device 40. The change enables the drawer 20 to be selectively maintained in the open or closed state.
