S1 is converted to a second working state S2 ), so that the second working piece 54 can pass over the first end 27 a of the blocking piece 26 . At this time, the second elastic force portion 56b is in a state of accumulating an elastic force (as shown in FIG. 18 ). On the other hand, the first work piece 52 responds to the elastic force of the first elastic force portion 56a in the first working state S1 (as shown in FIG. 17 ).

It is worth mentioning that, as shown in FIGS. 16 and 17 , when the second rail 24 continues to move in the first direction D1 relative to the first rail 22 , the sliding device 70 also moves in the first direction D1 displacement, wherein, the fastener 76 generates a force through the contact of the second guide section 87b with the second contact portion 59 of the base 56, so that the fastener 76 pivots from the above-mentioned first predetermined state X1 It is converted into a second predetermined state X2 at an angle, and a longitudinal section 61 of the base 56 can abut against the auxiliary structure of the fastener 76 to temporarily maintain the fastener 76 in the second predetermined state X2. The elastic force feature 78 of the fastener 76 is in a state of accumulating an elastic force.

As shown in FIG. 19 , when the second rail 24 is further displaced relative to the first rail 22 in the first direction D1 to an extension position E, the second rail 24 is blocked by the blocking member 26 .

For example, when the second rail 24 reaches the extending position E, the second work piece 54 returns from the second working state S2 to the first working state S1 in response to the second elastic force portion 56b releasing the elastic force. , the second working piece 54 is located at the second end 27b of the blocking piece 26 . On the other hand, the first working member 52 is in the first working state S1 and is located at the first end 27 a of the blocking member 26 . In other words, the first working piece 52 and the second working piece 54 are located at two opposite ends of the blocking piece 26 respectively. According to this configuration, the second rail 24 can be blocked by the first end 27a of the blocking member 26 through the first working member 52 in the first working state S1, so as to prevent the second rail 24 from going from the extended position E to the The displacement in the first direction D1; and the second rail 24 can be blocked by the second end 27b of the blocking member 26 through the second working member 54 in the first working state S1, so as to prevent the second rail 24 from The extension position E is displaced toward the second direction D2. At this time, the slide rail assembly is in an extended state (eg, a fully extended state, but not limited thereto). The first operating member 62 and the second operating member 64 can be respectively used to operate the first working member 52 and the second working member 54 to switch from the first working state S1 to the second working state S2 .

It is worth mentioning that, as shown in FIG. 19 , when the second rail 24 is further displaced in the first direction D1 relative to the first rail 22 to the extending position E, the sliding device 70 is also further moved to the first direction D1 The direction D1 is displaced, and the buckle section 86 of the buckle 76 in the second predetermined state X2 is staggered from the latching portion 66 of the first rail 22 .
