The invention relates to a hand-operated elevating mechanism for the installation of a revolving body. The hand-operated elevating mechanism for the installation of the revolving body comprises a first guiding seat and a second guiding seat. Left and right sides of the lower parts of the first guiding seat and the second guiding seat are respectively connected with s first pull-back spring and a second pull-back spring. Lower parts of the first pull-back spring and the second pull-back spring are respectively connected with a fixing base. Left and right sides of the upper parts of the first guiding seat and the second guiding seat are respectively connected with a supporting column. Moving nuts are respectively arranged on the lower parts of the first guiding seat and the second guiding seat. A lead screw is arranged on middle parts of the moving nuts. A shaft coupling is arranged on the right side of the lead screw, and a first transmission chain wheel is arranged on the left side of the lead screw. A speed reducer is arranged below the lead screw. A second transmission chain wheel is arranged at the left side of the speed reducer. A hand wheel is arranged in front of the speed reducer. According to the invention, the usage effect of the mechanism is effectively improved, manual elevating in the revolving body installation is convenient, the production and manufacturing effective is improved, and the mechanism can be conveniently used according to requirements.
