External antenna structure of router

The utility model discloses an external antenna structure of a router, and relates to the technical field of routers, the external antenna structure of the router comprises a shell, the inner wall of the shell is provided with two groups of grooves, the inner walls of the grooves are elastically connected with a sliding plate through springs, the outer wall of the sliding plate is fixedly connected with a plurality of groups of clamping blocks A, and the clamping blocks A are arranged in the grooves. A plurality of groups of sliding grooves are formed in the inner wall of the shell, connecting blocks are connected to the inner walls of the sliding grooves in a clamped mode, clamping blocks B are fixedly connected to the outer walls of the connecting blocks, and clamping grooves are formed in the outer walls of the connecting blocks. Therefore, the connecting block does not need to be mounted and dismounted by rotating the threads for multiple times, and the problem that the connecting block falls off from the
