Each limiting wall 23 and the first main wall 11 are located on either side of each first side wall 12 in the width direction D3. In this embodiment, the third fixing portions 24 are perforated and formed in the second main wall 21. Each third fixing portion 24 and the corresponding first fixing portion 13 are used for screwing and fixing with a screw lock assembly 5, which includes a screw 51 and a nut 52. In this embodiment, the two second positioning portions 25 are perforated and formed in the two second side walls 22. The two second positioning portions 25 and the two first positioning portions 15 are used for mutual positioning by means of concave-convex cooperation.

[0026] See Figures 1 to 3 and Figure 5 The third rod 3 can be in an extended position relative to the first rod 1 (see Figure 2 ) and a folded position (see Figure 7 ) pivots between the two first side walls 12 of the first rod 1. The third rod 3 has a third main wall 31 corresponding to the first main wall 11, two third side walls 32 connected to the third main wall 31 and located on both sides of the two first side walls 12 in the depth direction D2, and a plurality of fourth fixing portions 33 corresponding to the second fixing portions 14. Specifically, in this embodiment, each of the first side walls 12 of the first rod 1 has an outward-pushing wall portion 121 located at the bottom end, and the spacing between the outward-pushing wall portions 121 of the two first side walls 12 of the first rod 1 is approximately equal to the spacing between the two second side walls 22 of the second rod 2. The two third side walls 32 of the third rod 3 are pivotally connected to the two sides of the outward-pushing wall portions 121 of the two first side walls 12 of the first rod 1 via a pivot member 6 extending along the depth direction D2. In this embodiment, the fourth fixing portions 33 are perforated and formed in the third main wall 31. Each of the fourth fixing portions 33 and the corresponding second fixing portion 14 is used for screwing the screw assembly 5 to fix it.

[0027] The connection unit 4 is disposed on the first bar 1, the second bar 2 and the third bar 3, and is used to connect with the server cabinet 200. The connection unit 4 includes a plurality of fixed metal pieces 41 disposed on the first bar 1, the second bar 2 and the third bar 3, and a plurality of positioning holes 42 formed on the first bar 1, the second bar 2 and the third bar 3. The fixed metal pieces 41 are used to be mounted on the cabinet body 201 of the server cabinet 200, and the positioning holes 42 are used to position the slide rail unit 202 of the server cabinet 200. In the embodiment, the fixed metal pieces 41 are rotatably disposed on the first bar 1, the second bar 2 and the third bar 3, so as to be folded on the first bar 1, the second bar 2 and the third bar 3 before being mounted on the cabinet body 201 of the server cabinet 200, but the present application is not limited thereto.

[0028] When the second bar 2 is located at the extended position and the third bar 3 is located at the unfolded position, the second main wall 21 of the second bar 2 and the third main wall 31 of the third bar 3 abut on the same face of the first main wall 11 in the width direction D3, so that the second main wall 21 and the third main wall 31 are located in the same plane. The two first positioning portions 15 and the two second positioning portions 25 are positioned with each other by the concave-convex matching, so that the user can confirm that the second bar 2 is located at the extended position. Moreover, the first fixed portion 13 and the third fixed portion 24 are fixed to each other by the screw locking assembly 5, and the third fixed portion 24 and the fourth fixed portion 33 are fixed to each other by the screw locking assembly 5, so that the second bar 2 and the third bar 3 are maintained at the extended position and the unfolded position, respectively. At this time, the external hanging bracket 100 can be mounted on the cabinet body 201 of the server cabinet 200 and position the slide rail unit 202 of the server cabinet 200 by the connection unit 4. In the embodiment, when the second bar 2 is located at the extended position and the third bar 3 is located at the unfolded position, the second bar 2 can be located at the folded position first, and then the third bar 3 is located at the unfolded position, as shown in Figure 6 Figure 7

[0029] Referring to Figure 3 Since the interval between the outer push wall portions 121 of the two first side walls 12 of the first bar 1 is equal to the interval between the two second side walls 22 of the second bar 2, and the two third side walls 32 of the third bar 3 are pivoted on the two sides of the outer push wall portions 121 of the two first side walls 12 of the first bar 1, as described above. Figure 7 Figure 8 ​​​Therefore, when the second rod member 2 is located at the folding position and the third rod member 3 is located at the folding position, the two third side walls 32 of the third rod member 3 are located at two sides of the two second side walls 22 of the second rod member 2 in the depth direction D2, so that the two second side walls 22 of the second rod member 2 do not interfere with the two third side walls 32 of the third rod member 3. At this time, the second main wall 21 of the second rod member 2 and the third main wall 31 of the third rod member 3 are located at two sides of the first rod member 1 in the width direction D3, respectively. Overall, the second main wall 21, the two second side walls 22 and the two limiting walls 23 of the second rod member 2 and the third main wall 31 and the two third side walls 32 of the third rod member 3 together surround at least part of the first rod member 1 in the height direction D1, thereby effectively protecting the first rod member 1 which is relatively weak in structural strength.

[0030] In summary, in the present application, the second rod member 2 can be folded in a sliding manner, and the third rod member 3 can be folded in a pivoting manner, thereby making the external hanging bracket 100 easier to transport and less likely to be damaged during transportation. Moreover, through this structure of one sliding and the other folding, the second main wall 21 can be located in the same plane as the third main wall 31 when the external hanging bracket 100 is in use, and the second rod member 2 and the third rod member 3 can together surround at least part of the first rod member 1 in the height direction D1 when the external hanging bracket 100 is stored, thereby effectively protecting the first rod member 1 which is relatively weak in structural strength.

[0031] The above is only an embodiment of the present application, and cannot limit the scope of the present application. Any simple equivalent changes and modifications made in accordance with the claims and the content of the specification are still within the scope of the present application.
