An intersection of each of the side walls 874 and the top wall 876 forms a U-shaped and resilient pressing portion 878. Two sides of the pressing portion 878 protrude outwardly from the two blocks 879.

The unlocking member 89 is substantially Z-shaped and includes an elastic fixing piece 892, an operating piece 894 parallel to the fixing piece 892, and a connecting piece 896 perpendicularly connecting the fixing piece 892 and the operating piece 894. Two positioning holes 897 are defined in the rear end of the fixing piece. Two sides of the front end of the fixing piece 892 extend perpendicularly away from a side away from the operating piece 894 by a wedge-shaped block 898.

Referring to FIG. 5 to FIG. 7 together, when assembling, the operation piece 894 of the unlocking member 89 is inserted into the through hole 862 of the front plate 86 from the inside of the frame 82, so that the block 898 of the unlocking member 89 is inserted into the frame. In the corresponding slot 848 of the first side plate 84, the two screws are respectively threaded through the positioning holes 897 of the unlocking member 89 to the corresponding screw holes 849 of the first side plate 84. The free ends of the blocks 898 pass through the corresponding through slots. The 848 is exposed to the outside of the first side panel 84. Each fan 87 is inserted into the frame 82, and the block 879 of the outer frame 872 of the fan 87 slidably abuts against the corresponding rib 845, so that the two pressing portions 878 of each fan 87 are elastically deformed relatively close. Until the block 879 is facing the holding hole 846 of the corresponding rib 845, each pressing portion 878 is restored to deform so that the block 879 is held in the corresponding holding hole 846. In other embodiments, the unlocking member 89 and the frame body 82 may also be connected by riveting, welding, or the like.

The fixing piece 62 of the holding member 60 is abutted against the bottom surface of the base plate 42 of the connecting member 40. The two screws are respectively fixed to the corresponding screw holes 428 of the base plate 42 through the through holes 622 of the fixing piece 62. At this time, the holding member 60 is received between the two recessed portions 422 , and the latching block 642 of the holding piece 64 extends away from the substrate 42 .

A screw 88 is slidably passed through the positioning groove 442 of the flange 44 of the connecting member 40 to be screwed into the screw hole 844 of the first side plate 84 of the frame 82.

The connector 40 is inserted into the accommodating space 29 from the opening of the front side of the support frame 20 together with the fan assembly 80. The first guide post 222 in the accommodating space 29 is inserted into the corresponding first guide groove 426 from the introduction port 424 of the substrate 42. Pushing the frame 82 backward, the first guide post 222 pushes the connecting member 40 backwards, the screw 88 pushes against the rear end of the positioning slot 442, and the connecting member 40 slides into the receiving portion along the first guiding slot 426. The latching member 64 of the latching member 60 elastically deforms the latching piece 64 of the latching member 60 upwardly when the latching block 642 faces the corresponding guiding slot 224. The clip 64 is restored to deform such that the tab 642 snaps into the guide slot 224. The frame 82 is pushed back, and the block 898 of the unlocking member 89 abuts against the front end of the corresponding partition plate 28. The fixing piece 892 of the unlocking member 89 is elastically deformed away from the partition plate 28 to the unlocking member 89. The block 898 is deforming the corresponding fixing hole 282 of the partition 28, and the fixing piece 892 of the unlocking member 89 is deformed to cause the block 898 to be caught in the corresponding fixing hole 282. The air inlet 8752 of the fan 87 is facing the vent 860 of the front plate 86 of the frame 82.

Referring to FIG. 8 together, when the fan 87 is removed, the operation piece 894 of the unlocking member 89 is operated to release the fixing piece 892 of the unlocking member 89 from the fixing hole 282 of the partition plate 28 of the support frame 20. The handle 864 of the frame 82 is pulled outwardly, and the frame 40 is slid along the first guide slot 426 along the frame 82. The frame 82 is along the second guide of the connector 40. The sliding block 427 slides outwardly, and the block 642 of the holding member 60 slides outward along the corresponding guiding groove 224 and stops at the front end of the guiding groove 224. The screw 88 slides outward along the positioning groove 442 of the connecting member 40 and stops at the front end of the positioning groove 442. At this time, the fan 87 is completely exposed to the outside of the accommodating space 29 of the support frame 20. Pressing the pressing portion 878 of each fan 87 relatively, the pressing portion 878 is elastically deformed in a relatively close direction, and the block 879 of each pressing portion 878 is disengaged from the corresponding holding hole 846, and the fan 87 is extracted outward. Yes, without the need for tools.

When the connecting member 40 is removed from the support frame 20 together with the fan assembly 80, the front end of the holding piece 64 of the holding member 60 is pressed upward, and the holding piece 64 is elastically deformed upward to make the card. The catch 642 of the holder 60 exits the guide groove 224 of the support frame 20, and the handle 864 is pulled outward to separate the connector 40 from the support frame 20 without the use of a tool.
