The bottom surface of the support column 11 is fixedly connected to the top surface of the base plate 10 , and the bottom surface of the box body 12 is fixedly connected to the top surface of the support column 11 .

A rotating assembly 2 is arranged inside the box body 12, and the rotating assembly 2 includes a turntable 20, a surveying instrument body 21, a gear 22, a rocker 23, a circular plate 24, a worm 25 and a worm wheel 26; a partition plate 121 is arranged on the inner wall of the box body 12, one end of the worm 25 is rotatably connected to one side of the partition plate 121 through a bearing, the other end of the worm 25 passes through the side wall of the box body 12 and is fixedly connected to one side of the circular plate 24, and the other side of the circular plate 24 is fixedly connected to one end of the rocker 23; one end of the worm wheel 26 is rotatably connected to the bottom wall of the box body 12 through a bearing, and the other end of the worm wheel 26 is fixedly connected to the gear shaft of the gear 22, the gear shaft of the gear 22 passes through the top wall of the box body 12, the gear teeth of the gear 22 are meshedly connected to the outer wall of the turntable 20, and the top wall of the turntable 20 is fixedly connected to the surveying instrument body 21.

When the rocker 23 is rotated, the rocker 23 drives the circular plate 24 to rotate, and then drives the worm 25 to rotate. The worm 25 drives the worm wheel 26 to rotate by meshing with the worm wheel 26. The worm wheel 26 drives the gear 22 to rotate through the gear shaft. The gear 22 drives the turntable 20 to rotate. The turntable 20 drives the surveying instrument body 21 to rotate, thereby adjusting the observation angle of the surveying instrument body 21.

The outer wall of the base plate 10 is equidistantly provided with rotation grooves 101, and there are four rotation grooves 101, and the four rotation grooves 101 are all rotatably connected with the adjustment assembly 3. The adjustment assembly 3 includes a sleeve 30, a telescopic rod 31, a square plate 33, a knob 34, a first bevel gear 35, a second bevel gear 36 and a screw rod 37.

The outer wall of the sleeve 30 is rotatably connected to the rotating groove 101, the square plate 33 is fixedly connected to the upper inner wall of the sleeve 30, the gear shaft of the first bevel gear 35 penetrates and is rotatably connected to the side wall of the sleeve 30, one end of the gear shaft of the first bevel gear 35 is fixedly connected to a knob 34, the outer wall of the first bevel gear 35 is meshedly connected to the outer wall of the second bevel gear 36, the gear shaft of the second bevel gear 36 is rotatably connected to the bottom wall of the square plate 33 through a bearing, the bottom wall of the second bevel gear 36 is fixedly connected to one end of a screw rod 37, the top wall of the telescopic rod 31 is provided with a thread groove 311, and the screw rod 37 is threadedly connected to the thread groove 311 of the telescopic rod 31. By rotating the knob 34, the first bevel gear 35 is driven to rotate. The first bevel gear 35 drives the second bevel gear 36 to rotate, and the second bevel gear 36 drives the screw rod 37 to rotate, so that the height of the leg can be adjusted more conveniently and delicately.

In this embodiment, the telescopic rod 31 is a square rod, and the outer wall of the telescopic rod 31 is slidably connected to the inner cavity of the sleeve 30. The setting of the square rod allows the telescopic rod 31 to be limited by the sleeve 30 and cannot rotate, which is more stable.

The bottom wall of the telescopic rod 31 is fixedly connected with an anti-skid support foot 32, which serves to increase friction and make the telescopic rod 31 more stable after adjustment.

In this embodiment, only the upper half of the outer wall of the turntable 20 is provided with gear teeth and is meshedly connected to the outer wall of the gear 22. The top wall of the box body 12 is provided with a circular groove 122. The lower half of the outer wall of the turntable 20 is rotatably connected in the circular groove 122. The circular groove 122 serves to limit the turntable 20.

The front wall and one side of the outer wall of the box body 12 are both fixedly connected with a calibrator 14. The utility model is adjusted by observing the deflection angle of the calibrator 14, so that the surveying instrument body 21 is kept horizontal.

The front wall of the box body 12 is provided with an open end, and a drawer 13 is embedded in the open end of the box body 12. The drawer 13 can be used to hold sundries.

The outer side walls of the rocker 23 and the knob 34 are provided with anti-skid patterns, which serve to increase friction.

When the utility model is in operation, the adjustable surveying instrument for complex terrain is as follows: after the device is moved to a designated location, some large rocks and cracks are avoided by opening the rotating sleeve 30, the anti-skid feet 32 are extended and contact the ground, the deflection angles of the two calibrators 14 are observed and further adjusted; by rotating the knob 34, the first bevel gear 35 is driven to rotate, the first bevel gear 35 drives the second bevel gear 36 to rotate, and the second bevel gear 36 drives the screw rod 37 to rotate. Since the telescopic rod 31 is limited by the inner cavity of the sleeve 30 and cannot rotate, the telescopic rod 31 slides in the cavity of the sleeve 30 under the action of the thread friction force between the screw rod 37 and the thread groove 311, thereby adjusting the length of the adjustment component 3 to make the base plate 10 level.

The handheld joystick 23 moves in a circle, the joystick 23 drives the circular plate 24 to rotate, the circular plate 24 drives the worm 25 to rotate, the worm 25 drives the worm wheel 26 to rotate, the worm wheel 26 drives the gear 22 to rotate, the gear 22 drives the turntable 20 to rotate, the turntable 20 drives the surveying instrument body 21 to rotate, thereby adjusting the direction of the lens.
