description	The invention discloses a throttling device for measuring the aerodynamic performance of a fan, and the device comprises a mounting frame which forms an air inlet with a forward opening in a surrounding manner; the driving assembly is connected to the mounting frame and comprises a motor and a linear transmission pair, the motor rotates to drive the linear transmission pair, and a central shaft of the linear transmission pair and a central shaft of the air inlet coincide with each other; the center of the end socket is connected with the linear transmission pair, the end socket is slidably connected to the mounting frame in the front-back direction, and the front end of the end socket can extend forwards into or retreat from the air inlet through transmission of the linear transmission pair. The position of the end socket relative to the outlet of the test air duct can be controlled through an electric control means, the precision is high, climbing is not needed, and the position of the end socket is manually
