Grounding resistor

The invention relates to the technical field of construction devices, in particular to a grounding resistor. In the embodiment of the invention, the plurality of limiting pieces are arranged to be matched between the moving piece and the first part of the grounding piece, and the moving piece can move along the first direction relative to the first part under the condition that the first part of the grounding piece is inserted into the target pit and the acting force is applied to the barrel body to enable the barrel body to rotate; in the process that the moving piece gets close to or away from the first part in the first direction, the limiting piece can move close to or away from the central axis of the grounding piece. Therefore, through the mutual cooperation of the grounding piece, the moving piece, the limiting piece and the cylinder body, the grounding resistor can be conveniently used in the construction process, and the construction cost is reduced. 本申请涉及施工装置技术领域，本申请涉及一种接地电阻。在本申请实施例中，通过设置多个限位件配合于移动件
