Teleprompter and use method thereof

The invention belongs to the technical field of teleprompters, and discloses a teleprompter which comprises a teleprompter body, a fixing base, an air cylinder, a connecting rod, a linear motor, an air plug and a cooperation assembly. The side wall of the teleprompter body is provided with a cooperation assembly which can carry out pneumatic dust removal treatment on impurities such as dust adsorbed on the surface of the teleprompter body when the distance between the teleprompter body and a user is adjusted. When the teleprompter is used, the distance between the teleprompter body and a user can be automatically adjusted according to the needs of the user, manpower is greatly saved, and the adjusting efficiency is improved; and in the process of adjusting the distance between the teleprompter body and the user, dust and other impurities adsorbed on the surface of the reflecting glass on the teleprompter body can be removed, so that the user can see character information reflected by the surface of the reflec
