The level fixing plate 6 is horizontally arranged above the mounting plate 1, and the level fixing plate 6 is vertically adjusted through the adjusting device 3 arranged below the level fixing plate 6. Damping component 5 installs in 6 bottom both sides of spirit level fixed plate, can improve this bearing structure's stability through damping component 5, and the effectual engineering surveying level that prevents receives vibrations in the use and leads to the measuring result inaccurate.

Specifically, 3 supporting legs 2 adopt, set up along 1 outer wall circumference equidistance interval of mounting panel, are tripod bearing structure, and in this embodiment, mounting panel 1 is regular hexagon, and three supporting legs 2 upper end evenly distributed articulate in 1 outer wall of mounting panel. The lower extreme of supporting leg 2 is connected with connecting rod 20, and this connecting rod 20 upper end and supporting leg 2 lower extreme can be articulated also can be the rigid coupling, connecting rod 20 lower extreme is fixed with callus on the sole 21, callus on the sole 21 lower surface is fixed with first cushion 210 and second cushion 211 along length direction symmetry respectively, first cushion 210 with it has first sharp foot 23 and second sharp foot 24 to articulate between the second cushion 211, promptly first sharp foot 23 with second sharp foot 24 can the level hold in holding tank 213 that first cushion 210 and second cushion 211 constitute or be splayed structure and place in holding tank 213. Specifically, the heights of the first cushion block 210 and the second cushion block 211 are consistent, a rotating shaft 22 is transversely arranged between the first cushion block 210 and the second cushion block 211, and the rotating shaft 22 is located in the middle of the lengths of the first cushion block 210 and the second cushion block 211.

When the first and

second prongs

23 and 24 rotate outward (the first and

second prongs

23 and 24 both rotate outward away from the rotating shaft 22) to a horizontal position, the first and

second prongs

23 and 24 are accommodated in the accommodating groove 213 formed by the first and

second pads

210 and 211; and the first and

second prongs

23 and 24 are in a splayed configuration when relatively closed.

When the first sharp foot 23 and the second sharp foot 24 are spread when the first sharp foot 23 and the second sharp foot 24 are limited by the sharp foot when the terrain of different measuring places, such as complex terrains like potholes and sloping fields, needs to be limited by the sharp foot, the two elastic stop pieces 25 move from the second cushion block 211 to the corresponding grooves 2110, the elastic stop pieces 25 are limited in the grooves 2110, the first sharp foot 23 and the second sharp foot 24 are limited to rotate continuously, the first sharp foot 23 and the second sharp foot 24 are in a splayed structure at the moment, and then the first sharp foot 23 and the second sharp foot 24 are inserted into the ground, so that the support of the level is more stable and firm, and the anti-skid pad 212 can also assist in fixing on special occasions.

The elastic stopper 25 includes: a hollow rod 250, a movable rod 251, and a compression spring 252. One end of the hollow rod 250 is fixedly connected with the side wall of the first sharp foot 23 or the second sharp foot 24; the movable rod 251 is movably arranged in the hollow rod 250; the compression spring 252 is disposed in the hollow rod 250, and one end of the compression spring is connected to the inner bottom surface of the hollow rod 250, and the other end of the compression spring is connected to one end of the movable rod 251 inserted into the hollow rod 250. Therefore, when one end of the movable rod 251, which is far away from the compression spring 252, abuts against the inner wall of the second pad 211, the movable rod 251 compresses the spring 252, and the compression spring 252 gives a certain pressure to the movable rod 251, so that the first pointed leg 23 and the second pointed leg 24 are generally limited from moving, and the pointed legs can be stably and horizontally accommodated in the accommodating grooves 213. When the movable bar 251 moves into the groove 2110, the compression spring 252 pushes the movable bar 251 into the groove 2110 due to the restoring force of the compression spring 252, thereby restricting the first and

second prongs

23 and 24 from continuing to rotate.
