First, the adjustment plate (503) needs to be grasped and pushed to the left. During the adjustment process, the connecting plate (502) will compress the internal support spring (501), and at the same time, the plug-in plate (5) on the right will be embedded in the inside of the main chassis (1). After the plug-in plate (5) is separated from the slot (403), the metal frame (401) and the acrylic plate (4) are pushed to move. During the movement, the splicing slide column (402) will slowly slide along the splicing slide groove (106), and the internal structure can be exposed by sliding; S2, the user then removes the bolts connecting the main fixing plate (3) and the main case (1), then simultaneously buckles the two sets of auxiliary notches (303) and pulls the auxiliary plate (302) to move the main fixing plate (3) along the metal guide rod (105). After the movement, the main fixing plate (3) can be taken out as a whole. After the removal, the electronic equipment such as the motherboard, power supply, graphics card, etc. that need to be installed are fixed on the top of the main fixing plate (3). After the fixing, the main fixing plate (3) is installed into the main case (1) along the metal guide rod (105) and is fixed to the main case (1) again by the bolt structure. After the fixing, the movable fixing plate (2) on the back is controlled to slide along the limit column (201) to keep the movable fixing plate (2) and the interface surface on the back of the mainboard connected by bolts; S3, then place the cooling fan to be installed directly on the top of the support plate (603), and after splicing the two sets of cooling fans, insert the corresponding opening of the limit slide groove (602) into the inner side of the pull-out groove (102). During the insertion process, the limit slide groove (602) will be spliced ​​with the limit slide rail (104). After splicing, continue to insert the combination plate (601) and the front of the main box (1) to keep it flush, and then directly control the adjustment knob (604) to drive the internal flip buckle (605) to embed into the inner side of the positioning groove (103). After installation, splice and install the acrylic plate (4); S4. Finally, when the main box (1) is to be transported, the two sets of handle frames (704) and the splicing flip block (703) need to be flipped along the positioning axis (702). After flipping, they will be spliced ​​together to form a handle structure. After splicing, the main box (1) can be lifted by grasping the combined handle (7) at the bottom. During the lifting process, the strong spring (707) and the damping rod (705) will provide a certain degree of buffering, thereby reducing the pressure on the user's hands during the transport process. In the non-carrying state, the two sets of handle frames (704) can be unfolded, and items can be placed after unfolding.
