Preferably, the path 438 is disposed on the second member 408 and adjacent to the second engaging portion 415 , the path 438 has an inclined surface, and the engaging member 428 can displace along the path 438 . When the second member 408 is displaced in a first moving direction M1, the engaging member 428 is displaced to a predetermined position on the path 438 and abuts against the first engaging portion 413 of the first member 406 and the second member 408 The second member 408 can drive the first member 406 to move toward the first moving direction M1 by means of the engaging member 428 between the second locking portions 415 .

18 and 19 show that when the second member 408 is displaced in a second moving direction M2, the engaging member 428 is displaced by the second engaging portion 415 of the second member 408, and the movement from the path 438 When the predetermined position is separated, the second member 408 cannot drive the first member 406 to move in the second moving direction M2 by means of the locking member 428 .

As shown in FIG. 20 , the second rail 60 is at a retracted position P1 relative to the first rail 58 . At this time, the swinging member 78 is located at the locking portion 306 of the locking device 300 , and the first elastic member 104 of the first driving device 100 abuts against the locking portion 306 by the swinging member 78 to maintain a first driving force F1 . In this state, the second elastic portion 322 of the guiding member 304 elastically abuts against the swinging member 78 . On the other hand, the catching member 208 has a catching feature 226 catching the locking feature 68 of the first rail 58 , and the catching feature 226 can be a buckle or a recess. In addition, the pushing member 220 contacts the blocking member 206 in response to the elastic force generated by the auxiliary elastic member 218 . The stopper 108 of the first base 102 of the first driving device 100 is in contact with the stopper 206 of the second driving device 200, and the stopper 108 of the first base 102 of the first driving device 100 corresponds to the first A notch 228 of the second base 202 of the second driving device 200 . The buffer member 500 includes a buffer rod 502 capable of abutting against the blocking member 206 .

As shown in FIG. 21 , since the catch 208 and the locking feature 68 of the first rail 58 are engaged with each other, when an external force in the first direction D1 is applied to the second rail 60 , the second rail 60 is opposite to each other. The first rail 58 will be displaced from the retracted position P1 toward the first direction D1, and the pushing member 220 will respond to the external force, and press the auxiliary elastic member 218 against the blocking member 206, so that the second The rail 60 moves from the retracted position P1 relative to the first rail 58 to the first direction D1 for a short distance. . On the other hand, the swinging member 78 moves along with the second rail 60 toward the first direction D1 to expand the guiding member 304 and disengage from the locking portion 306 .

As shown in Figures 22 and 23, during the displacement of the second rail 60 in the first direction D1, the second base 202 of the second driving device 200 is provided with a release feature, for example, a first push part 230 corresponds to For the control part 416 of the clutch 402, the control part 416 is disengaged from the first feature 412 of the first member 406 of the clutch 402 by pushing the first push part 230. At this time, the second part of the clutch 402 Member 408 is free to rotate. On the other hand, the second base 202 of the second driving device 200 is also provided with a second push portion 232 corresponding to the contact piece 424 of the elastic device 420 of the clutch 402, so that the contact piece 424 can be pushed to make the elastic device The elastic force of 420 will not be applied to the control member 416 .

As shown in FIGS. 24 and 25, when the swinging member 78 is disengaged from the locking portion 306 of the locking device 300, the second elastic portion 322 of the guide member 304 can elastically guide the swinging member 78, so that the swinging member 78 When the member 78 is displaced to the second path 312 of the guide channel 308, the first elastic member 104 of the first driving device 100 releases the first driving force F1, so that the second rail 60 moves from the above-mentioned retracted position P1 relative to the The first rail 58 is displaced in a second direction D2. Specifically, after the first elastic member 104 of the first driving device 100 further releases the first driving force F1, the second base 202 of the second driving device 200 and the second rail 60 will further move relative to the first rail. 58 is displaced in the second direction D2. That is, the second rail 60 can extend and open relative to the first rail 58 in response to the elastic force of the first elastic member 104 . Wherein, in the process of releasing the elastic force of the first elastic member 104, the swing member 78 will be displaced from the second path 312 of the guide channel 308 toward the third path 314; on the other hand, the second driving device 200 When the second base 202 is displaced in the second direction D2, the guide portion 216 of the second driving device 200 is displaced relative to the catcher 208 . In addition, the buffer rod 502 of the buffer member 500 is extended to be in a buffer ready state and can correspond to the blocking member 206 of the second driving device 200 . As mentioned above, the swinging member 78 is operatively locked between the locking portion 306 and the guiding member 304, so that the first elastic member 104 of the first driving device 100 maintains the first driving force F1; and The swinging member 78 is operatively released from between the locking portion 306 and the guiding member 304 to release the first driving force F1 to drive the second furniture part from a retracted position relative to the first furniture part.

When the external force is not enough to make the swinging member 78 latch on the locking portion 306 of the locking device 300, once the external force is released, the second rail 60 will move relative to the first elastic force by releasing the first elastic force and the second elastic force. A rail 58 will be ejected for displacement. On the other hand, based on the aforesaid clutch device 400 being in a locked state, the clutch device 400 can only move in the second direction D2 relative to the auxiliary track 66, thus providing a blocking force for the first base 102, so The first base 102 (not shown in this figure) of the first driving device 100 cannot be displaced, and when the second base 202 of the second driving device 200 is displaced relative to the first rail 58 in response to the external force, the first The elastic member 104 is stretched by the second base 202 to store elastic force, and the second elastic member 204 is pulled by the second base 202 because the guide pin 234 of the catcher 208 is stuck against the second guide section 224 Stretch and store stretch. The swing member 78 can be displaced relative to the locking device 300 from the third path 314 to the first path 310 , on the other hand, the second push portion 232 of the second base 202 can push against the clutch device 400 The contact piece 424 is moved to move the contact piece 424 by a distance S.
