Moving, the second lever 72 is located between the first lever 71 and the stopper 5. Please refer to the sixth figure again, and the first lever 71 is used to engage the release claw mechanism 61. The groove 67 is configured to enable the first lever 71 to move the release device 6 on the rail 321 of the fixing mechanism 3; as shown in the third and sixth figures, the drawer 1 of the present invention is used. When the starting system is in the pulled-out state, the release claw mechanism 61 is pulled out by the first lever 71, and the rotating arm 642 is rotated and clamped into the longitudinal notch portion 322 of the rail 321 . At this time, the buffer rod mechanism 4 has its compression spring 43 in an uncompressed relaxed state and pushes the stopper 5 against the side of the limiting block 323, and at the same time, the fixing seat The tension spring 33 of the structure 3 will be in a stretched tension state and will store a reverse elastic force.

At this point, the creation process of returning the slide rail to the reset is completed; please refer to the seventh diagram and the eighth section. As shown in the figure, when the user is inconvenient to directly open the drawer by hand, the drawer can be slightly pushed inwardly and then released, and the first lever 71 can continue to drive the release device 6 to move inward. a small distance, at this time, because the end of the rotating arm 642 of the swaying claw 64 is abutted by the protrusion 324, the swaying claw 64 and its rotating arm 642 can be rotated relative to the releasing claw body 63, when the rotating arm When the 642 is rotated to a certain angle, the rotating arm 642 will be in a lying direction, and the left abutting surface 643 will no longer abut the first lever 71. Therefore, when the user's limb is released from the drawer, please Referring to the ninth figure, the buffer rod mechanism 4 can release its elastic force by the compression spring 43, so that the compression spring 43 can drive the stopper 5 and the second lever 72 to be outwardly ejected, and the first lever 71 can also be ejected outward through the upper portion of the rotating arm 642 without hindrance. Until the block 5 is blocked by the limiting block 323, the creation process has completed the action of automatically ejecting the drawer through pressing; please refer to the ninth and tenth views, when the user continues to pull the drawer outward When pulled out, the second lever 72 will move outward and push against the oblique baffle 634 of the release device 6 which releases the claw body 63, so that the second lever 72 can drive the entire release device 6 to move outward. When the rotating arm 642 moves to the position of the longitudinal notch portion 322, the torsion spring 65 can release its stored elastic restoring force and drive the rotating claw 64 and its rotating arm 642 to rotate, so that the rotating arm 642 is stuck. In the longitudinal notch portion 322, the second lever 72 also drives the release claw body 63 to rotate relative to the driving member 62 toward the longitudinal notch portion 322, so that the release claw body 63 is obliquely blocked. The block 634 no longer resists or blocks the second lever 72, and the user can continue to pull the drawer outward, and the creation process of all the opening and closing drawers has been completed; As shown in the second and third figures, the creation uses swaying The rotating arm 642 of the 64 and the protrusion 324 of the track 321 serve as switches for controlling the spring return of the compression spring 43 and the stopper 5, and the push-open function can be realized in a simplified structure, thereby enabling the creation. The utility model can reduce the manufacturing cost and improve the reliability of the product. In addition, as shown in the fourth figure, the movable rod 41 of the buffer rod mechanism 4 is directly disposed on the fixing portion 31 of the fixing body 31.
