The first positioning member 54 includes an elastic section 56 and a locking portion 58 connected to the elastic section 56 . Preferably, the engaging portion 58 extends from the elastic section 56 . The engaging portion 58 covers the first installation hole 46 , so that the at least one fixing member 34 cannot be disengaged from the first installation hole 46 by the first positioning member 54 . More specifically, during installation, the at least one fixing member 34 passes through the first installation hole 46 and supports the first positioning member 54 until the at least one fixing member 34 is displaced to the fixing hole 48 , The at least one fixing member 34 breaks away from the supporting relationship with the first positioning member 54, and the first positioning member 54 covers the first installation hole 46 by the elastic force of its elastic section 56, so that the at least one fixing member 34 The first positioning member 54 cannot be disengaged from the first installation hole 46 arbitrarily. If the at least one fixing member 34 intends to disengage from the first mounting hole 46, the first positioning member 54 is opened relative to the inner rail 20, and the at least one fixing member 34 can be displaced from the fixing hole 48 to the first mounting hole 46. A mounting hole 46 is disengaged.

Similarly, the configuration of the second positioning member 55 is the same as that of the aforementioned first positioning member 54 , and will not be repeated here.

As shown in Figures 4 and 5, when at least one fixing member 34 of the first cabinet 30 passes through the first mounting hole 46 and moves to the fixing hole 48, the first positioning member 54 simultaneously The hole 46 is covered so that the at least one fixing member 34 cannot be disengaged from the fixing hole 48 , that is, the first cabinet 30 is fixed.

The at least one sliding portion 44 of the inner rail 20 includes a blocking portion 60. When the at least one sliding member 36 passes through the second mounting hole 50, it is displaced to the sliding slot 52, and at the same time, the second positioning member 55 moves the first The two mounting holes 50 are covered so that the at least one sliding member 36 cannot disengage from the sliding slot 52 , that is, the at least one sliding member 36 can be displaced within the sliding slot 52 for a limited distance S1 . In other words, referring to FIG. 6, applying an external force F to the second cabinet 32 can cause the second cabinet 32 to displace relative to the first cabinet 30, that is, when the second cabinet 32 relatively slides away from the first cabinet 30 When reaching the maximum distance, the at least one sliding member 36 can abut against the blocking portion 60 .

Referring to FIG. 4 again, when the second cabinet 32 relatively slides toward the first cabinet 30 , the at least one sliding member 36 can abut against the engaging portion 58 of the second positioning member 55 .

According to the above description, it can be seen that the enhancement effect and advantages of the present invention are:

a. In the present invention, the at least one sliding part 36 passes through the at least one sliding portion 44 of the inner rail 20 to add another function of the inner rail 20 .

b. On the other hand, the present invention can also effectively solve the problem that the wiring between components or modules in the cabinet 16 is complicated and the space is narrow, and it is not easy to remove the wiring to replace components.
