▎ 摘　　要

NOVELTY - The switch has a casing (2) that is connected in the middle of the whole device. The overlapping blocks are connected around the bottom end of the casing. The two ends of the casing are embedded and connected with a filter screen (5), and the inner top of the casing is embedded and connected with a shunt cavity (6). The inner wall of the casing is connected with a graphene layer (8), and the inner two sides of the casing are connected with a condensation pipe (7). A lifting column is connected to the top of the connecting plate, and a lap plate is connected to the top of the lifting column. A threaded rod is connected to the middle of the telescopic plate. A spring clamping column is connected to the left ends of the spring limiting column, and a telescopic column is connected to the left side of the spring clamping column. The bottom of the elevating column is connected with anti-skid lines, and the inner bottom of the elevating column is connected with a damping spring. USE - Computer internet of things (IoT) switch such as Ethernet switch, telephone voice switch and fiber switch. ADVANTAGE - The overall cooling effect of the device is greatly improved. The protective mechanism has a dust-proof effect on the interface, is convenient to clamp and fix the wire tube of the external wiring, avoids the connection between the external wiring and the interface due to the sagging of the wire tube and greatly improves the overall practicability of the device. The lifting mechanism is convenient for the user to adjust the lifting method of the casing according to the actual situation and the lifting of the casing increases the overall heat dissipation effect of the device. The detachable lifting mechanism is convenient for the user to disassemble and replace the damaged lifting mechanism alone, and the stability of the lifting column is increased through the shock-absorbing spring and the anti-skid pattern.
