Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution:A kind of portable gradiometer of land surveying, packet
Include main body 1 on gradiometer, the side of main body 1 is fixedly connected with button block 17 on gradiometer, and the surface of main body 1 opens up on gradiometer
Through hole is fixedly connected with fixed link 2, and the surface activity of fixed link 2 is connected with roller bearing 3, and the both ends of roller bearing 3 are fixed with pointer 4
Connection, and the quantity of pointer 4 is two, the surface of roller bearing 3 has been respectively fixedly connected with pointer 4 and pendular body 5, and pendular body 5 is separate
One end of roller bearing 3 is fixedly connected with gravity sphere 6, by the roller bearing 3 being connected in fixed link 2, pointer 4 and pendular body 5 is made to match
Closing gravity sphere 6 can change with the gradient and corresponding angle occur, and main body 1 is provided with hand holding handle 7 on gradiometer, hold
The surface of handle 7 is fixedly connected with anti-skid bulge 8, and the lower surface of main body 1 is fixedly connected with main body 9 under gradiometer, slope on gradiometer
The lower surface of main body 9 is provided with the bar slot 15 that contacts to earth under degree instrument, and the surface of main body 9 is provided with arc-shaped cavity 16, the gradient under gradiometer
