A connecting block 82 is fixedly connected to the inner side of the connecting plate 81. The connecting block 82 is slidably connected to the surface of the support rod 2 through a through hole. A replacement component 83 is provided at the bottom of the connecting plate 81.

[0026] As a technical optimization solution of the utility model, by setting a connecting component 8, the four fixing rods 7 are connected to each other through the connecting plate 81 and the connecting block 82, so that the fixing rods 7 can rise and fall synchronously, avoiding the situation where the fixing rods 7 are not synchronized when moving, resulting in the base plate 1 being fixed and skewed.

[0027] refer to Figure 2 The limiting assembly 9 includes a limiting hole 91 , which is opened at the bottom of the surface of the support rod 2 , and a limiting rod 92 is inserted into the limiting hole 91 .

[0028] As a technical optimization solution of the utility model, by setting a limit assembly 9, when the operator pulls the fixing rod 7 out of the ground through the connecting assembly 8, the operator inserts the limit rod 92 into the limit hole 91, so that the limit rod 92 limits the connecting block 82, avoiding the situation where the fixing rod 7 is always in contact with the ground when the universal wheel 5 drives the base plate 1 to move.

[0029] refer to Figure 2 The bottom of the fixing rod 7 is fixedly connected with a cone thorn 10.

[0030] As a technical optimization solution of the utility model, by providing the cone thorn 10, the cone thorn 10 is fixedly installed with the fixing rod 7, so that the fixing rod 7 can be easily inserted into the ground through the cone thorn 10, thereby improving the convenience of inserting the fixing rod 7 into the soil.

[0031] refer to Figure 2 A pull rod 11 is fixedly connected to the top of the connecting plate 81 , and a pull ring 12 is fixedly connected to the top of the pull rod 11 .

[0032] As a technical optimization solution of the utility model, by setting the pull rod 11 and the pull ring 12, when the operator needs to pull out the fixed rod 7 through the connecting assembly 8, the operator pulls the pull ring 12 to drive the pull rod 11 and the connecting assembly 8 to move upward, so that the connecting assembly 8 drives the fixed rod 7 to be pulled out from the inside of the ground, thereby improving the convenience of the operator in pulling out the fixed rod 7.

[0033] refer to Figure 4 The bottom of the surface of the fixing rod 7 is fixedly connected with a barb 13, and a plurality of barbs 13 are arranged and distributed in a circular shape with equal distances.

[0034] As a technical optimization solution of the utility model, by providing the barbs 13, when the fixing rod 7 is inserted into the soil, the barbs 13 can increase the friction between the fixing rod 7 and the soil, thereby improving the stability of the fixing rod 7 inserted into the soil.

[0035] refer to Figure 4 The replacement component 83 includes a threaded hole 831, which is opened at the bottom of the connecting plate 81. The top of the fixing rod 7 is fixedly connected with a screw 832 used to match the threaded hole 831. The fixing rod 7 is fixedly connected to the connecting plate 81 through the screw 832 and the threaded hole 831.

[0036] As a technical optimization solution of the utility model, by setting a replacement component 83, when the fixing rod 7 is damaged and needs to be replaced, the operator can rotate the fixing rod 7 in the opposite direction so that the fixing rod 7 drives the screw 832 to disengage from the threaded hole 831, and then the operator can rotate the new fixing rod 7 into the threaded groove through the screw 832, thereby improving the convenience of the operator in replacing the fixing rod 7.

[0037] The working principle and use process of the utility model are as follows: when in use, the limiting rod 92 is in the state of being inserted into the limiting hole 91. When the operator needs to fix the bottom plate 1, the operator pulls the limiting rod 92 out of the limiting hole 91. At this time, the limiting rod 92 no longer blocks the connecting block 82, so that the operator steps on the connecting block 82 and the connecting plate 81 downward, so that the connecting block 82 and the connecting plate 81 generate downward pressure and drive the fixing rod 7 and the cone thorn 10 to penetrate into the soil, thereby completing the fixation, so that the barb 13 can increase the friction between the fixing rod 7 and the soil, thereby improving the stability of the fixing rod 7 inserted into the soil. When the operator needs to pull out the fixing rod 7, the operator pulls the pull rod 81 to release the friction between the fixing rod 7 and the soil. The ring 12 drives the connecting plate 81 and the connecting block 82 to move upward through the pull rod 11, so that the connecting plate 81 and the connecting block 82 drive the fixing rod 7 to be pulled out from the soil, and the operator inserts the limiting rod 92 into the limiting hole 91, so that the limiting rod 92 limits the connecting block 82, avoiding the situation that the fixing rod 7 is always in contact with the ground when the universal wheel 5 drives the base plate 1 to move. When the fixing rod 7 is damaged and needs to be replaced, the operator rotates the fixing rod 7 in the opposite direction, so that the fixing rod 7 drives the screw 832 to disengage from the threaded hole 831, and then the operator rotates the new fixing rod 7 into the threaded groove through the screw 832, thereby improving the convenience of the operator in replacing the fixing rod 7.

[0038] In summary, the laser rangefinder for urban and rural planning is provided with a sliding hole 6, a fixing rod 7, a connecting assembly 8 and a limiting assembly 9. When the operator needs to fix the bottom plate 1 on a soft ground, the operator removes the limiting assembly 9, and then the operator steps on the connecting assembly 8 downward, so that the connecting assembly 8 generates downward pressure and drives the fixing rod 7 and the cone thorn 10 to penetrate into the soil through the sliding hole 6, thereby completing the fixation, ensuring the stability of the laser rangefinder body 4 when used on soft ground, and solving the problem that the above-mentioned equipment adopts a planar supporting structure as a support for measurement, and is prone to tipping over when placed on some soft ground, which affects the measurement work and is relatively limited.
