[0035] Operation process: The driving component 202 in the cable management mechanism 200 drives the cable management mechanism to run together, and the cables of different thicknesses are sorted step by step. After the cable management is completed, the cable management wheel 201c and the driving component 202 can be separated, and the driving component 202 can be operated alone to continue to operate the cleaning mechanism 300. Similarly, the cable management wheel 201c can be rotated alone for multiple circles to perform separate cable management work. The side cleaning component 301 and the bottom cleaning component 302 in the cleaning mechanism 300 can also clean the locations in the cabinet that are inconvenient to clean.

[0036] Example 2

[0037] Reference Figure 1-4, this embodiment is different from the first embodiment in that: the driving assembly 202 includes a baffle 202a disposed on the cable management shaft 201b, a driving member 202b disposed on the baffle 202a, and an arc plate 202c disposed on the baffle 202a, wherein the arc plate 202c can slide on the baffle 202a, so that the arc plate 202c can squeeze and drive the wing plate 201d to rotate, thereby driving the cable management assembly 201 to rotate;

[0038] The driving member 202b includes a driving knob 202b-1 arranged on the cable management shaft 201b, a diamond block 202b-2 arranged on the driving knob 202b-1, and a driving plate 202b-3 arranged on the arc plate 202c, wherein the driving knob 202b-1 drives the cable management shaft 201b to rotate when it rotates, and a first connecting rod element 202b-4 connected between the diamond block 202b-2 and the driving plate 202b-3; a rubber friction pad is arranged on one side of the arc plate 202c, and the purpose of such arrangement is to enable the arc plate 202c to drive the cable management assembly 201 to rotate simultaneously when it is squeezed with the wing plate 201d, and the driving plate 202b-3 is adapted to the curvature of the arc plate 202c.

[0039] Furthermore, the side cleaning component 301 includes a side cleaning port 301a disposed on the accommodating cabinet 101, a connecting shaft 301b disposed in the side cleaning port 301a, and a cleaning roller 301c disposed on the connecting shaft 301b, wherein the cleaning roller 301c in the side cleaning component 301 can clean the side dust when rolling, and can also make the dust fall into the dust trough 303, so as to facilitate subsequent centralized processing.

[0040] Furthermore, the bottom cleaning component 302 includes a bottom cleaning port 302a arranged on the accommodating cabinet 101, a bottom cleaning push plate 302b arranged in the accommodating cabinet 101, and a second connecting rod element 302c arranged on the bottom cleaning push plate 302b, wherein the second connecting rod element 302c can drive the bottom cleaning push plate 302b to slide, so that the bottom accumulated dust is pushed into the dust accumulation groove 303 for subsequent centralized processing.

[0041] The rest of the structure is the same as that of Example 1.

[0042] Operation process: When the main body is working and cleaning, the cable management shaft 201b is driven to rotate by rotating the driving knob 202b-1, so that the side cleaning component 301 is driven by the subsequent mechanism to clean the side of the accommodating cabinet 101. Similarly, the bottom cleaning component 302 cleans the dust on the bottom of the accommodating cabinet 101. During this process, the cable management component 201 that does not need to rotate needs to be fixed and limited by the limiting shaft 201c-1 and the limiting groove 201c-2 to avoid motion interference and cause jamming during the operation.

The arrangement of the pneumatic piston 501c enables the lifting block 501a to drive the smooth block 502b to operate, thereby driving the related side cleaning assembly 301 and the bottom cleaning assembly 302 to operate simultaneously.

[0047] The rest of the structure is the same as that of Example 2.

[0048] Operation process: During the upward process, rotating the driving knob 202b-1 can make the first bevel gear 402b drive the second bevel gear 402c to rotate, thereby causing the meshing shaft 402a to rotate. At this time, the lifting block 501a will descend on the meshing shaft 402a. At this time, the side cleaning assembly 301 will clean the side of the accommodating cabinet 101. At the same time, the pneumatic piston member 501c can drive the bottom cleaning assembly 302 to clean the bottom of the accommodating cabinet during the descent of the lifting block 501a. The side cleaning assembly 301 and the bottom cleaning assembly 302 will push the accumulated dust into the dust accumulation groove 303, and then carry out subsequent centralized treatment.
