Engineering machinery manipulation control device

The utility model relates to the technical field of mechanical control, in particular to an engineering machinery operation control device. A telescopic rod is directly arranged on a driving pump body, one end of the telescopic rod is pivoted to the driving pump body, and the other end of the telescopic rod is pivoted to a driving pump swing rod; compared with a traditional mode of controlling rotation of the swing rod through flexible shaft stretching and retracting, the structure is simple, small in occupied space and easy to arrange, the stretching and retracting amount of the telescopic rod can be accurately controlled by controlling electric signals, therefore, the rotating angle of the driving pump rotating shaft is more accurately controlled, the operation comfort is good, and the problem of flexible shaft abrasion does not exist; the telescopic rod is connected with a cab through an electric wire and can be arranged along with a whole vehicle wire harness, and compared with a flexible shaft connection
