[0025] Specifically, the bottom end surface of screw sleeve 8 is rotatably connected with annular block, and the cross section of annular block is T-shaped, the bottom end of vertical rod 9 is fixedly connected with annular block, when screw sleeve 8 is rotated, screw sleeve 8 drives vertical rod 9 and arc-shaped plate 10 to move downward through the rotation of thread, so as to tightly abut spherical block 4, thereby facilitating the fixation of spherical block 4. In addition, the connection mode of spherical block 4 and hemispherical cover 3 makes the angle range of threaded cylinder 5 larger and the flexibility better.

[0026] The lateral wall of screw rod 6 is fixedly connected with handle 17 near the bottom end. Handle 17 facilitates the hand holding of screw rod 6, and when the length of threaded cylinder 5 and screw rod 6 is adjusted, threaded cylinder 5 is conveniently rotated, and threaded cylinder 5 is prevented from driving screw rod 6 to rotate synchronously.

[0027] The top surface of placing plate 2 is provided with a plurality of evenly distributed positioning holes 18. It is convenient for the supporting feet on other models of level gauges to be clamped into positioning holes 18.

[0028] Example 2
