DETAILED DESCRIPTION

[0016] like Figure 1-6As shown: A construction surveying and mapping device includes a suitcase, which includes a box body 1 and a box cover 2; the box body 1 and the rear side wall of the box cover 2 are rotatably connected, two lock buckles 3 are arranged between the front side wall of the box body 1 and the box cover 2, the front side wall of the box body 1 is fixedly connected with a handle 4, the bottom of the box body 1 is rotatably connected with three supporting legs 5, the top center of the box cover 2 is provided with a measuring instrument 6, the bottom of the box body 1 is provided with a plurality of mounting holes 7, the top of the supporting leg 5 is rotatably connected with a mounting plate 56, the four corners of the mounting plate 56 are all plugged with screws 57, the screws 57 and the mounting holes 7 are threaded In coordination, four mounting holes 28 are provided in the center of the top of the box cover 2, and the mounting holes 28 are square. The bottom of the measuring instrument 6 is fixedly connected with a mounting seat 61, and the bottom of the mounting hole 28 is provided with a screw 262, which penetrates the mounting hole 28 and is threadedly connected with the mounting seat 61. A plurality of limit blocks 9 are fixedly connected to the inner bottom wall of the box body 1, and placement grooves are formed between the limit blocks 9. The limit blocks 9 are clamped with four supporting legs 5 and the measuring instrument 6. A plurality of hexagonal wrenches 10 are nested on the inner bottom wall of the box body 1, and the hexagonal wrenches 10 are compatible with the screw 1 57 and the screw 2 62.
