The slider 7 is slidably connected in the outer ring guide rail 2, and the bottom edge of the slider 7 is a convex-shaped sinking design. The inner bottom surface of the outer ring guide rail 2 is fixedly connected to an annular rubber pad 3, and the inner and outer positions of the two sides of the bottom edge of the slider 7 near the rubber pad 3 are A plurality of rollers 15 are rotatably connected to the inner bottom surface of the outer ring guide rail 2, and a lifting plate 18 is embedded in the center of the bottom surface of the slider 7. The bottom edge of the lifting plate 18 is fixedly connected to an anti-slip strip 19 for pressing against the rubber pad 3. The upper surface of the slider 7 is sleeved with a plug-in 8. Both sides of the plug-in 8 pass through the top edge of the slider 7 and extend to be fixedly connected to the top edge of the lifting plate 18. The top edge of the slider 7 is also fixedly connected to a screw rod 16 that passes through the plug-in 8, and an adjusting nut 17 threadedly connected to the screw rod 16 is rotatably connected to the upper surface of the plug-in 8. When in use, the adjusting nut 1 is adjusted by rotating the adjusting nut 1 7 realizes that the plug-in 8 drives the lifting plate 18 to rise until the anti-skid strip 19 on its surface is separated from the rubber pad 3, and the slider 7 can be slid in the outer ring guide rail 2 through the set several rollers 15, thereby realizing the sliding adjustment position of the distance measuring mechanism. In addition, when the position of the slider 7 needs to be fixed, it is only necessary to rotate the adjusting nut 17 in the opposite direction to realize the plug-in 8 to descend along the surface of the screw rod 16, thereby realizing the lifting plate 18 to descend until the anti-skid strip 19 on its surface is tightly against the surface of the rubber pad 3, and the slider 7 is fixed in the outer ring guide rail 2 by utilizing the engagement between the anti-skid strip 19 and the surface of the rubber pad 3.

[0025] In order to fix the seismic exploration instrument 1: a plurality of threaded tubes 9 are fixedly connected to the inner side of the inner ring guide rail 4, a tightening screw 10 is inserted in the threaded tube 9, and an adjusting screw ring 14 threadedly connected to the tightening screw 10 is rotatably connected at the tube mouth of the threaded tube 9.
