A connecting frame 18 is fixedly connected to the upper surface of the first connecting disk 6. A regulating rod 17 for supporting and adjusting the mounting base 7 is rotatably connected in the vertical direction of the connecting frame 18. A movable block 21 is horizontally slidably connected to the first connecting disk 6. The movable block 21 is movably connected to a push rod 16. One end of the push rod 16 away from the movable block 21 is movably connected to the regulating rod 17;

[0029] When the movable block 21 moves on the first connecting disk 6 towards or away from the movable sleeve 13, it can push or pull the regulating rod 17 movably connected to the connecting frame 18, causing the angle between the regulating rod 17 and the connecting frame 18 to change. At the same time, the mounting base 7 fixedly connected to the connecting block 15 is pushed and adjusted. The regulating rod 17 swings on the connecting frame 18 to adjust the horizontality of the mounting base 7, so that the mounting base 7 is kept horizontally arranged, avoiding measurement errors caused by the inclination of the instrument, thereby improving the accuracy of the surveying results.

[0030] There are four connecting frames 18, and the four connecting frames 18 are distributed in a circular array on the upper surface of the first connecting disk 6. By setting four connecting frames 18, and adjusting the regulating rods 17 at different positions, the mounting base 7 can be quickly set horizontally. The four connecting frames 18 are respectively rotatably connected to the regulating rod 17 in the vertical direction through pins, which can ensure stable support for the mounting base 7.

[0031] The surface of the first connecting disk 6 is provided with chutes 20 distributed in a circular array. Each regulating rod 17 is provided with a corresponding movable block 21.

Rotating the handle fixedly connected to the second screw rod 22 can limit the sliding of the movable block 21 screwed to the second screw rod 22 in the chute 20. When the movable block 21 moves, it pushes the push rod 16, and through the push rod 16, the regulating rod 17 movably connected to it is pushed to swing, adjusting the support position of the mounting base 7 to make the mounting base 7 horizontally arranged.

[0032] A connecting piece 19 is fixedly connected to the lower surface of the bearing seat 1. The connecting piece 19 is rotatably connected to a support rod 2 through a pin. One end of the support rod 2 away from the bearing seat 1 is penetrated and limitedly slidably connected to a telescopic rod 3. The telescopic rod 3 is pulled to expand and contract, and the fixed knob on the support rod 2 is rotated to fix the position of the support rod 2.
