Reflector with adjustable reflecting surface

The invention relates to a reflector with an adjustable reflecting surface, which particularly comprises an electromagnetic wave lens, a reflecting mechanism, a vacuum pump and a moving mechanism, the electromagnetic wave lens is of a spherical structure; the reflection mechanism comprises a shell and an elastic membrane; the shell is located between the electromagnetic wave lens and the moving mechanism, and the shell is installed on the moving mechanism; the moving mechanism is used for controlling the shell to move; an opening and a connecting hole are formed in the shell; the elastic membrane covers the opening of the shell, and a reflecting surface is arranged on the elastic membrane; the vacuum pump is used for controlling the vacuum degree of the inner cavity of the shell and is hermetically communicated with the connecting hole of the shell through a pipe fitting; the vacuum pump is electrically connected with the moving mechanism, and the vacuum pump and the moving mechanism work cooperatively, so th
