The invention discloses an electric multi-roller finder for parameters and standards, which comprises a case body and at least two roller units are mounted in the case body. The roller unit comprises a first roller and a second roller, which can be rotatably mounted on the case body, reading scroll belts for recording the parameter and standard are wound and tensioned on the first roller and the second roller, and the case body is provided with window units which correspond to the roller units and are used for displaying the content of the reading scroll belts. The roller comprises an active end fixed with a belt transmission mechanism and a passive end erected on the case body, the first roller is fixedly connected with the electric motor of the drive belt transmission mechanism, and theoutput shaft of the electric motor is arranged in the case body in a penetrated mode. The electric motor is electrically connected with a control panel on the surface of the case body, and the control panel is provided with a forward button and a back button for rotating the electric motor anticlockwise. The electric multi-roller finder for parameters and standards has the advantages of accurately, fast and correctly finding the parameters and standards needed for design and operation.
