[0022] During the specific implementation, it is only necessary to rotate the support column 15 so that the support column 15 is level with the protective block 12, and then push the protective block 12 so that the protective block 12 pushes the fixed block 23 to move and leave the fixed groove 22. At this time, rotate the protective block 12 so that it is aligned with the through-hole 21 to remove the protective block 12. To install the protective block 12, you only need to align the fixed block 23 with the through-hole 21, and then push the protective block 12 so that it drives the fixed block 23 to pass through the through-hole 21 and push the reinforcement block 25 to compress the spring 26. At this time, rotate the protective block 12 so that it drives the fixed block 23 to rotate and align with the fixed groove 22. At this time, let go, and the compressed spring 26 will push the reinforcement block 25 to move, so that the reinforcement block 25 pushes the fixed block 23 into the fixed groove 22, completing the installation. At this time, rotate the support column 15 so that its bottom contacts the base plate 1 and it can be used normally.

[0023] like Figure 2 The fixing device 3 shown includes a support platform 31, which is slidably installed in the slide groove 16. A motor 32 is fixed on the top of the support platform 31, and a handle 33 is rotatably installed on the top of the motor 32.

The rotor part of the motor 32 passes through the base plate 1 and is fixedly connected to the drill string 35. A pair of hooks 34 are provided, and a pair of hooks 34 can better support the column motor 32 to prevent the motor 32 from moving downward. A magnetic coupler 5 is fixedly installed at the connection between the rotor part of the motor 32 and the drill string 35. The drill string 35 is fixedly connected to the rotor part of the motor 32 through the magnetic coupler 5. The magnetic coupler 5 can adopt a model such as HSFO8, which can be disconnected when the load is too large, thereby protecting the motor 32.

[0024] During the specific implementation, it is only necessary to hold the handle 33, lift the motor 32 upwards and then rotate the handle 33, so that the handle 33 leaves the hook 34 and then start the motor 32. The rotation of the motor 32 will drive the drill string 35 to rotate. At this time, hold the handle 33 to slide the motor 32, so that the drill string 35 contacts the ground, and then the drill string 35 drills into the ground, thereby fixing the base plate 1.

[0025] like Figure 4 The mobile device 4 shown includes a threaded hole 41, which is opened at the bottom of the base plate 1. A threaded column 42 is connected to the threaded hole 41, and a universal wheel 43 is fixedly installed at the bottom of the threaded column 42.
