Zusammenfassung:	The utility model pertains to an engineering implement and discloses a hydraulic control device of the excavator. Currently, the operating board of the hydraulic system of the excavator is provided with six operating handles, wherein, four handles need be ceaselessly operated with transposition in the hands of the operator to realize work, the prior hydraulic control device is inconvenient when in use. An improved handle is adopted now, wherein, a handle groove(6) is combined with a reversing valve rod(5), a handle groove(13) is combined with reversing valve rod(12), adjusting and operating completely, and eliminating the problem of inconvenience when in use.
