By providing structures such as a fixed column 3, a limiting round block 4, a reset spring 5, a dust cover 6 and a handle 7, the handle 7 is pulled to drive the dust cover 6 to slide on the outer wall of the fixed column 3. During the sliding process, the dust cover 6 will squeeze the reset spring 5 toward the position of the limiting round block 4. After squeezing for a certain distance, the interface 16 will be exposed, and then the connector and the interface 16 can be connected. When no wiring is required, the connector only needs to be removed from the interface 16. After removal, the rebound force of the reset spring 5 will restore the dust cover 6 to its original position, so that it can cover the broadband amplifier body 2 and its interface 16, thereby improving the dust-proof effect of the broadband amplifier body 2 and its interface 16, and effectively preventing dust from easily entering the interface 16 when no wiring is required.

[0025] See also Figure 1-2 One end of the reset spring 5 is fixedly connected to the limiting round block 4, and the other end of the reset spring 5 is fixedly connected to the dust cover 6. The fixed connection improves the stability of the reset spring 5 during use. The surface of the mounting plate 1 is symmetrically penetrated with mounting holes 15.

[0026] Embodiment 2

[0027] See also Figure 3-4A fixing block 8 is fixedly installed on the back of the broadband amplifier body 2, and slots 9 are provided on both sides of the fixing block 8. A reserved groove 10 is provided on the side of the mounting plate 1 close to the broadband amplifier body 2, and a bidirectional threaded rod 11 is installed inside the reserved groove 10. The outer wall of the bidirectional threaded rod 11 is symmetrically threaded with a rectangular plate 12, and an insert block 13 is fixedly installed on the side of the rectangular plate 12 close to the fixing block 8. A rotating block 14 is fixedly installed on one end of the bidirectional threaded rod 11, and the rotating block 14 is rotated to drive the bidirectional threaded rod 11 to rotate. During the rotation process, the bidirectional threaded rod 11 will drive the two groups of rectangular plates 12 to slide in opposite directions inside the reserved groove 10, and the two groups of rectangular plates 12 will drive the insert block 13 to slide together during the sliding process. After sliding a certain distance, the plug block 13 will be away from the slot 9. After moving away, the fixing block 8 and the broadband amplifier body 2 can be disassembled together, which makes it convenient for the operator to replace the damaged broadband amplifier body 2, and effectively avoids the need to use tools when disassembling the broadband amplifier body 2. The plug block 13 is slidably connected to the slot 9, and the fixing effect of the fixing block 8 is improved through the sliding connection. The rectangular plate 12 is slidably connected to the reserved groove 10, and the limiting effect of the rectangular plate 12 during adjustment is improved through the sliding connection, which effectively avoids the deflection of the rectangular plate 12 during adjustment.

[0028] Working principle: when wiring, first pull the handle 7, and the dust cover 6 is driven by the handle 7 to slide on the outer wall of the fixed column 3. During the sliding process, the dust cover 6 will squeeze the reset spring 5 toward the position of the limiting round block 4. After squeezing a certain distance, the interface 16 will be exposed, and then the connector and the interface 16 can be connected. When not wiring, just remove the connector from the interface 16. After removal, the rebound force of the reset spring 5 will restore the dust cover 6 to its original position, so that it can cover the broadband amplifier body 2 and its interface 16, thereby improving the dust-proof effect of the broadband amplifier body 2 and its interface 16, and effectively preventing dust from easily entering the interface 16 when not wiring. When the broadband amplifier body 2 is damaged and needs to be replaced, the rotating block 14 is rotated to drive the bidirectional threaded rod 11 to rotate. During the rotation process, the bidirectional threaded rod 11 will drive the two groups of rectangular plates 12 to slide in opposite directions inside the reserved groove 10. During the sliding process, the two groups of rectangular plates 12 will drive the plug-in block 13 to slide together. After sliding a certain distance, the plug-in block 13 will move away from the slot 9. After moving away, the fixed block 8 and the broadband amplifier body 2 can be disassembled together, thereby making it convenient for the operator to replace the damaged broadband amplifier body 2, and effectively avoiding the need to use tools when disassembling the broadband amplifier body 2.
