[0002] A waveguide is a hollow, smooth metal conduit or metal-lined tube. It is used to transmit ultra-high-frequency electromagnetic waves, allowing pulse signals to reach their destination with minimal loss. The inner diameter of a waveguide varies depending on the wavelength of the signal being transmitted. It is commonly used in radio fields such as centimeter-wave and millimeter-wave radio communications, radar, and navigation. Common waveguides include rectangular waveguides, circular waveguides, semicircular waveguides, Ku waveguides, radar waveguides, and optical waveguides.

At the same time, when the waveguide tubes need to be replaced or disassembled, the same steps need to be performed to operate the waveguide tubes. The connection and disassembly are inconvenient and the efficiency is low. Utility Model Content

The outside of the telescopic rod 3 is connected with a telescopic spring 4. The spring 4 can fix the blocking rod 3000 after the blocking rod 3000 is inserted into the inner part of the card slot 2101, so that the first waveguide tube 1 and the second waveguide tube 2 are connected to each other. The second waveguide tube 2 is provided at one end of the first waveguide tube 1. The top of the second waveguide tube 2 is fixedly connected with an arc head 2100. A card slot 2101 is recessed inwardly between the arc head 2100 and the second waveguide tube 2. A fitting groove 2103 is provided at the connection between the side of the card slot 2101 and the arc head 2100. The outer sleeve of the card slot 2101 It is connected to a disassembly ring 2102, and both ends of the middle protrusion of the disassembly ring 2102 are provided with inclined surfaces, which can enable the blocking rod 3000 to slide until one end presses against the disassembly ring 2102 and is engaged with the inside of the interlocking groove 2103, so that the blocking rod 3000 can continue to detach from the inside of the slot 2101 through the inclined surface. The interlocking groove 2103 is used to receive one end of the disassembly ring 2102 so that a connection relationship is formed between the side surface of the other end of the disassembly ring 2102 and the arc head 2100, so that the telescopic rod 3 can detach from the inside of the slot 2101.

[0023] See also Figure 1-4 One end of the telescopic spring 4 is fixedly connected to the top of the second limit plate 3002, and the other end of the telescopic spring 4 is fixedly connected to the top of the fixed groove 1002.

Since the second limit plate 3002 raised below the telescopic rod 3 can be squeezed by the arc head 2100 at the top of the second waveguide tube 2 entered by one end of the telescopic spring 4, the telescopic rod 3 is pushed out of the fixed groove 1002 inside the slot 2101 under the action of its own elastic force to fix the connection between the first waveguide tube 1 and the second waveguide tube 2. When the waveguide tube needs to be disassembled, the blocking rod 3000 is provided with an oblique angle. The first waveguide tube 1 is pushed in the direction so that the bevel of the blocking rod 3000 passes over the top of the disassembly ring 2102 to connect the waveguide tube; when the waveguide tube needs to be disassembled, the end of the blocking rod 3000 without the bevel is pressed against the side of the disassembly ring 2102 to drive the disassembly ring 2102 to the end of the card slot 2101 and engage it into the interior of the interlocking groove 2103. The interlocking groove 2103 receives one end of the disassembly ring 2102 so that a connection relationship is formed between the side surface of the other end of the disassembly ring 2102 and the arc head 2100, so that the telescopic rod 3 can be separated from the interior of the card slot 2101.
