[0002] GNSS receivers are used to monitor the displacement of the ground surface online for a long time. After the equipment is installed, it is no longer manually moved. When the ground surface is slightly displaced, the data monitored by the GNSS equipment will also change, thereby monitoring the displacement of the ground surface. GNSS receivers are suitable for monitoring the surface settlement and slope of mines with large ranges, many monitoring points, and low observation frequency, as well as monitoring the displacement of landslides and earth-rock dams.

[0004] When the above-mentioned receiver is in use, a support assembly and a fixing assembly are arranged, and the above-mentioned assemblies cooperate with each other. When the fixing rod is inserted into the ground, the support is unfolded, and the contact area between the receiver and the ground is increased through the support rod and the base. However, the support rod is only used to provide auxiliary support for the fixing rod. When the receiver is placed on an inclined terrain, the supporting effect of the support rod will be poor.

The receiver body 1 is arranged on the top of the placement tube 2. When in use, the receiver body 1 can be installed by placing the placement tube 2 on the corresponding ground. In order to make the placement tube 2 more stable when placed on the ground, a plurality of through holes 3 can be opened at the bottom of the placement tube 2, and a plurality of through holes 3 are movably provided with limit pins 4. A driving member is arranged inside the placement tube 2, and the driving member is used to drive the plurality of limit pins 4 to move away from each other.
[0032] like Figure 1-Figure 4 As shown, the plurality of limit pins 4 have a first working state and a second working state. When the plurality of limit pins 4 are in the first working state, that is, Figure 1 and Figure 2 In the state shown, the plurality of limit pins 4 are respectively located in the corresponding through holes 3. The staff can insert the bottom of the placement tube 2 in this state downward into the corresponding ground soil, and then the plurality of limit pins 4 in this state can be transformed to the second working state. When the plurality of limit pins 4 are in the second working state, that is, Figure 3 and Figure 4 In the state shown, multiple limit pins 4 are away from each other and respectively penetrate the corresponding through holes 3. Multiple limit pins 4 penetrate the through holes 3 and are inserted into the soil to further support the placement pipe 2 around, thereby ensuring the installation stability of the placement pipe 2.
[0033] like Figure 1 and Figure 3 As shown, when the ground is rugged, such as slope, as long as the pipe 2 is placed Figure 1 After the state shown is installed, the driving member can be used to make the multiple limit pins 4 pass through the multiple through holes 3 respectively, so that the multiple limit pins 4 can be inserted into the soil around the placement pipe 2 to better support and limit the placement pipe 2. This state can be Figure 3 In order to facilitate the installation of the placement pipe 2 on the corresponding ground, the bottom of the placement pipe 2 can be arranged in a conical shape, and a plurality of limit pins 4 are arranged at the conical position of the placement pipe 2.
