[0002] Switch means "switch" and is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch. Other common ones include telephone voice switches, fiber optic switches, etc. Switching is a general term for the technology of sending the information to be transmitted to the corresponding route that meets the requirements in accordance with the needs of information transmission at both ends of the communication, using manual or automatic methods of equipment. Switches can be divided into wide area network switches and local area network switches according to their working locations. A wide area switch is a device that completes the information exchange function in a communication system, and it is used in the data link layer. A switch has multiple ports, each of which has a bridging function and can connect a local area network or a high-performance server or workstation. In fact, switches are sometimes called multi-port bridges.

[0023] See also Figure 1-5 The utility model provides an embodiment: a switch that is easy to maintain, including a switch housing 1, a middle rear end of one end surface of the switch housing 1 and a middle front end of the other end surface of the switch housing 1 are fixedly connected with a fixing piece 101, a card slot 102 is provided at the upper end of one side of the fixing piece 101, and a rectangular limiting groove 103 is provided on the upper end surface of the card slot 102, a fixing column 2 is fixedly connected to both sides of the middle of the front and rear end surfaces of the switch housing 1, and a top rod 202 is connected to the upper end of the fixing column 2, an upper cover 3 is connected to the upper end of the switch housing 1, a fixing tube 301 is fixedly connected to one side of the middle rear end of the lower end surface of the upper cover 3 and the other side front end of the middle of the lower end surface of the upper cover 3, a limiting plate 302 is fixedly connected to one side of the fixing tube 301, a movable rod 4 is provided inside the fixing tube 301, and one side of the movable rod 4 extends out of one side of the fixing tube 301 and is fixedly connected to a locking tongue 401.

[0024] Furthermore, a telescopic groove 201 is provided at the upper end of the fixed column 2, a spring 203 is provided at the lower end of the telescopic groove 201, and the lower end of the push rod 202 is inserted into the telescopic groove 201. When the upper cover 3 is installed on the switch housing 1, the lower end surface of the upper cover 3 presses down the upper ends of the four push rods 202 at the same time, so that the push rods 202 are retracted into the telescopic groove 201 and the spring 203 is compressed.

[0025] Furthermore, a rectangular limiting portion 402 is fixedly connected to the upper end of a locking tongue 401 at one end of the movable rod 4. The locking tongue 401 at one end of the movable rod 4 is inserted into the slot 102 of the fixing member 101 and the rectangular limiting portion 402 is inserted into the rectangular limiting slot 103. By inserting the locking tongue 401 into the slot 102, the upward movement of the movable rod 4 is restricted, and the upward movement of the fixing tube 301 is restricted, so that the upper cover 3 is fixed to the upper end of the switch housing 1.

[0026] Furthermore, the other side of the movable rod 4 extends out of the other side of the fixed tube 301 and is fixedly connected to a rack 403 .

[0027] Furthermore, a limiting tube 5 is fixedly connected to the middle of the lower end surface of the upper cover 3 , and a rotating shaft 501 is rotatably connected inside the limiting tube 5 .
