[0029] A measuring instrument 8 is fixedly installed on the adjusting disc 6, and a bubble level 9 is fixedly connected to the mounting disc 4.

[0030] As can be seen from the above, the user can place the measuring tool on the ground through the support legs 2, roughly adjust the mounting disc 4 to a horizontal position through the adjusting assembly 3, then rotate the adjusting screws 7, so that the adjusting disc 6 rotates on the ball head rod 5, finely level the adjusting disc 6, observe the bubble level 9, until the adjusting disc 6 is adjusted to be horizontal, then install the measuring instrument 8 on the adjusting disc 6 for use.

[0031] In order to lift the measuring instrument 8 to a suitable height for use, the support leg 2 is a telescopic rod, and the lower end of the support leg 2 is provided with a pointed end for being inserted into the ground.

[0032] The adjusting assembly 3 comprises an upper hemisphere 31 and a lower hemisphere 32 arranged in the mounting sleeve 1, the bottom of the upper hemisphere 31 is rotationally connected with a screw rod 33, the lower end of the screw rod 33 penetrates through the lower hemisphere 32 and extends below the lower hemisphere 32, the lower hemisphere 32 is threadedly connected with the screw rod 33, and the upper end and the lower end of the mounting sleeve 1 are both provided with openings.

[0033] As can be seen from the above, when the mounting disc 4 is adjusted to be horizontal, the positions of the upper hemisphere 31 and the lower hemisphere 32 can be adjusted by the screw rod 33, so that the screw rod 33 is as vertical to the horizontal plane as possible, and thus the mounting disc 4 mounted on the upper hemisphere 31 is as parallel to the horizontal plane as possible.

[0034] In order to reduce the friction force suffered by the lower hemisphere 32 during the adjustment, a plurality of mounting holes 34 are formed in the side wall of the lower hemisphere 32, a spring 35 is arranged in each mounting hole 34, a rotating ball 36 is clamped at the outlet of each mounting hole 34, the rotating ball 36 abuts against the spring 35, the two ends of the spring 35 abut against the inner wall of the mounting hole 34 and the side wall of the rotating ball 36 respectively, the spring 35 is in a pre-compressed state, the spring 35 outwardly pushes the rotating ball 36, and the rotating ball 36 rolls between the mounting sleeve 1, thereby reducing the friction force suffered by the lower hemisphere 32.

[0035] When the screw rod 33 is substantially vertical to the horizontal plane, the upper hemisphere 31 and the lower hemisphere 32 are separated by rotating the screw rod 33, as the distance between the upper hemisphere 31 and the lower hemisphere 32 increases, the distance between the mounting sleeve 1 and the lower hemisphere 32 becomes smaller, the mounting sleeve 1 pushes the rotating ball 36 into the inside of the mounting hole 34, so that the outer wall of the upper hemisphere 31 and the lower hemisphere 32 directly abut against the inner wall of the mounting sleeve 1, thereby increasing the friction force suffered by the upper hemisphere 31 and the lower hemisphere 32, and preventing the upper hemisphere 31 and the lower hemisphere 32 from rotating.
