Adjustment control device with coder and coder structure

The utility model relates to an adjustable control device provided with an encoder, which comprises an encoder mechanism and a casing group. The encoder mechanism comprises a base, a circuit board and an encoder. The circuit is arranged on one side of the base. A fixed axis is formed on the other side. The encoder combined with the base has an electric connection with the circuit board. The casing group comprises a pressing casing, a combination seat, a rotating seat and a bearing seat. The pressing casing is arranged on one side of the base. The combination seat connected with the encoder is arranged on the other side of the base, which is positioned in the rotating seat. The rotating seat is connected with the combination seat, which makes the combination seat and the rotating seat are combined with the encoder. The bearing is arranged on one side of the combination seat and the rotating seat. One end of the fixed axis is connected with the bearing seat. By designing the structure of the encoder mechanism, the utility model has the function of clockwise/anticlockwise rotating repeatedly so as to provide a better application effect.
