When the measuring device 23 needs to work in a horizontal state, the second thread bush 10 can be rotated, so that the counterweight head 9 is separated from the workbench 1, the position of the second sliding block 20 on the supporting ring 13 can be adjusted as required, the limiting rod 18 is inserted into the limiting hole 19 and the second sliding block 20, the placing plate 22 can rotate around, the placing plate 22 is in a horizontal state under the action of the counterweight head 9, and the measuring device 23 above the placing plate can work after being opened.
When the measuring device 23 needs to keep a fixed angle for working, the second thread bushing 10 can be rotated, so that the counterweight head 9 abuts against the workbench 1, the angle of the placing plate 22 and the workbench 1 is parallel, the angle of the workbench 1 is adjusted by adjusting the distance between the first supporting rod 4 and the second supporting rod 6 below, namely, the placing plate 22 can work at different angles, and meanwhile, the counterweight head 9 can be adjusted to be in contact with the workbench 1 when the device is not used or is transported and moved, and the placing plate 22 stops rotating, so that the whole device is stable in the moving process, and the protection effect can be further achieved.
The device can be stably placed on the ground of the complex terrain by the sliding of the first sliding block 3 and the sliding chute 2, and the placing plate 22 can be kept in a horizontal state by the counterweight head 9, so that the measuring device 23 can work in a horizontal state even when the device is placed in an inclined state in the complex terrain, and the working stability of the whole device is improved.
