[0038] In this embodiment, the support leg 3 is provided with a fixing slot 24 , and the telescopic leg 4 is telescopically disposed in the fixing slot 24 .

[0039] The support member further includes a fixing bolt 23, a fixing plate 25 and a knob 26. The fixing bolt 23 is arranged in the fixing slot 24, one end of the fixing bolt 23 is fixedly connected to the telescopic leg 4, and the other end protrudes to the notch of the fixing slot 24. The fixing plate 25 and the knob 26 are arranged in the notch, the fixing plate 25 is sleeved on the fixing bolt 23, and the knob 26 is threadedly connected to the fixing bolt 23, and the knob 26 is turned to make the fixing plate 25 press against the surface of the supporting leg 3, so that the position of the supporting leg 3 and the telescopic leg 4 is fixed.

[0040] In a possible embodiment, the support member further includes a ground block 5 and a protective cover 6, wherein the ground block 5 is fixedly connected to one end of the telescopic leg 4 away from the supporting leg 3, and the protective cover 6 is rotatably connected to one end of the telescopic leg 4 away from the supporting leg 3, and the protective cover 6 can be rotated to a position corresponding to the ground block 5 to protect the ground block 5.

[0041] In this embodiment, the protective cover 6 is rotatably connected to the telescopic foot 4 via a bolt.

[0042] In a possible embodiment, the protective cover 6 is provided with a groove, the groove includes an arc groove 7 and a limit groove 8, the limit groove 8 is provided at both ends of the arc groove 7, the limit groove 8 is connected with the arc groove 7, and a limit rod 9 is movably provided in the groove, and the limit rod 9 can be moved into the limit groove 8 under force to fix the protective cover 6.

[0043] In this embodiment, the limiting groove 8 includes a first groove 8a and a second groove 8b. One end of the arc groove 7 is connected to the first groove 8a, and the other end is connected to the second groove 8b.

[0044] The telescopic foot 4 is provided with a groove 11, and a tension spring 12 is provided in the groove 11. One end of the tension spring 12 is fixedly connected to the side wall of the groove 11, and the other end is connected to the limit rod 9. The limit rod 9 protrudes from the groove 11 to the channel and extends to the side of the channel away from the groove 11. The protective cover 6 rotates on the telescopic foot 4 so that the limit groove 8 corresponds to the groove 11, so that the tension spring 12 pulls the limit rod 9 into the limit groove 8, and the limit rod 9 abuts against the groove side wall of the limit groove 8 to fix the protective cover 6. When the limit rod 9 enters the first groove 8a, the protective cover 6 is fixed at a position away from the ground piercing block 5, so that the ground piercing block 5 is exposed; when the limit rod 9 enters the second groove 8b, the protective cover 6 moves to a position corresponding to the ground piercing block 5, so that the protective cover 6 covers the ground piercing block 5.

[0045] The end of the limiting rod 9 away from the groove 11 is fixedly connected to the pressing plate 10, and the pressing plate 10 is flat. This is conducive to applying a force to the pressing plate 10 to drive the limiting rod 9 to overcome the elastic force of the tension spring 12, so that the limiting rod 9 moves from the limiting groove 8 to the arc groove 7.

[0046] The end of the protective cover 6 away from the limiting rod 9 is connected with a supporting foot 22. When the protective cover 6 rotates to the position corresponding to the ground-fixing block 5, the supporting foot 22 contacts the ground instead of the ground-fixing block 5. When the ground is muddy, the ground-fixing block 5 is fixed to the ground; when the ground is cemented, the supporting foot 22 contacts the ground, so that the ground-fixing block 5 can be protected and prevented from being worn.

[0047] When the urban planning survey measuring device of this embodiment is in use, the connecting rod 17 is folded into a handle shape through the rotating shaft 18 to rotate the threaded rod 19, and the threaded rod 19 drives the threaded sleeve 20 to move downward on the surface of the threaded rod 19, and the threaded sleeve 20 drives the hinged rod 21 to move, and then the support leg 3 is unfolded through the hinged rod 21, and then the telescopic leg 4 is adjusted for fine adjustment, and the measuring instrument 31 is adjusted to a horizontal state in combination with the observation level 28. When the urban planning survey measuring device is on the mud, the ground block 5 is used to penetrate the mud. When it is on a hard ground such as a cement ground, the ground block 5 may be worn and damaged. At this time, the pressing plate 10 is pressed downward, and the limit rod 9 leaves the first groove 8a and enters the arc groove 7. At this time, the protective cover 6 rotates. When the support foot 22 at the bottom of the protective cover 6 falls to the ground, the limit rod 9 is stuck in the second groove 8b to fix the position of the protective cover 6, and the protective cover 6 then protects the ground block 5.

[0048] In summary, the legs 3 of the urban planning surveying device of this embodiment are simultaneously spread out and maintained at the same angle, which can provide more stable support, reduce measurement errors, and make the results of urban planning surveys more accurate. When used on hard ground, the protective cover 6 can protect the ground block 5, making the urban planning surveying device suitable for various terrains. The protection of the ground block 5 helps to reduce wear and damage of the equipment, extend its service life, and reduce maintenance costs.

[0049] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
