[0002] A grounding device is a general term for a grounding electrode buried underground and the connecting wire from the grounding electrode to the equipment. The grounding device consists of a grounding electrode, a grounding busbar, a grounding down conductor, and a frame grounding. The grounding device is also called an integrated grounding device, which is a device that establishes an electrical connection between electrical equipment or other objects and the ground. It is used to connect the electrical system to the earth. The metal object that is in direct contact with the earth to achieve electrical connection is the grounding electrode.

[0003] The new grounding devices in the prior art generally emphasize the stability of the grounding device. The current grounding devices are generally installed with a tripod support and inserted into the soil. However, it should be considered that when a problem occurs with the grounding device and it needs to be removed for maintenance, excessive fixation of the grounding device will cause trouble for the staff to remove it, increasing the workload of the staff. At the same time, if the staff uses too much force when removing it due to leakage due to firm fixation, accidents are likely to occur.

[0004] In summary, in order to avoid over-fixation and ensure the stability of the grounding device, a new type of grounding device is designed, the purpose of which is to ensure that the grounding device can be fixed while ensuring portability when taken out. Utility Model Content
