1. A device for horizontal and vertical adjustment in geodetic devices comprising within its housing:

  • a horizontal adjusting system including a first fine adjustment drive for rotation of the device about a vertical standing axis;

    a vertical adjusting system including a second fine adjustment drive for the movement of a telescope which is mounted in a support of the device so as to be swivelable about a horizontal tilt axis;

    a coaxial drive which is arranged at the support of the device and having two coaxially mounted shafts, each having a manually operated non-motorized rotating knob structured for driving the rotation and/or movement of the respective parts and subassemblies;

    said first fine adjustment drive and the second fine adjustment drive each comprising a worm and a worm gear with a friction clutch, wherein the said fine adjustment drives can be actuated jointly from a location for generating movement in two movement directions running vertical to one another or at an angle to one another;

    said fine adjustment drives being arranged in two planes situated at different heights in the housing of the device, wherein the worm of one of said two fine adjustment drives lies in the plane of the coaxial drive;

    each worm gear of said two fine adjustment drives being connected, via a friction clutch, with the part or subassembly to be moved or rotated; and

    said fine adjustment gear unit whose worm does not lie in the plane of the coaxial drive being in an operative connection, via a quarter-turn belt drive, with one of the shafts of the coaxial drive.
