Further, when the third rail 36 is displaced in the first direction D1 relative to the second rail 30 until the displacement reaches a predetermined stroke, the second working member 86 will contact the stopper 88 of the second rail 30 A first side (as shown in Figure 13). When the third rail 36 continues to move in the first direction D1 relative to the second rail 30, the second working member 86 interacts with the stopper 88 to cause the second working member 86 to move from the first state S1 It can deflect an angle to a second state S2 (as shown in FIG. 14) and can pass over the first side of the stopper 88. At this time, the second elastic part 98b is in the state of cumulative elasticity until the third rail 36 When the second rail 30 is further displaced in the first direction D1 to reach a fully extended position Y (as shown in FIG. 15), the second working member 86 returns to the first position in response to the release of the elastic force of the second elastic portion 98b In a state S1, at this time, the second working member 86 is located on a second side of the blocking portion 88 (as shown in FIG. 15); on the other hand, the first working member 84 is in the first state S1 located in the blocking Part 88 on the first side. In short, when the third rail 36 is in the fully extended position Y relative to the second rail 30 (as shown in FIG. 15 ), the third rail 36 passes through the first work piece 84 and the second work piece 86 They are in the first state S1 and are located on the first side and the second side of the stop 88 and are blocked by the stop 88 to prevent the The third rail 36 is displaced from the fully extended position Y toward the first direction D1 or the second direction D2.

As shown in FIGS. 15, 16 and 17, when the third rail 36 is in the fully extended position Y with respect to the second rail 30, if the user wants the third rail 36 to move from the fully extended position Y to the When the first direction D1 or the second direction D2 is displaced, the user can operate the first working member 84 or the second working member 86 is no longer in the first state S1. For example, the user may apply a force in the first direction D1 to the first operating member 100, so that a driving portion 100a of the first operating member 100 can drive the first working member 84 to deflect from the first state S1 From an angle to another state (for example, the second state S2, as shown in FIG. 16), the third rail 36 can be displaced from the fully extended position Y toward the first direction D1 to the second channel of the second rail 30 54 outside. In other words, the third rail 36 can be detached from the second rail 30.
