Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The T-shaped end grounding rod of a kind of distribution as shown in Figure 1, including insulating bar 1, all-teeth screw 2, outer tube 3, ground connection
Line 4 and attaching nut's seat 5, the bottom end of the all-teeth screw 2 is provided with a prism 21, and the insulating bar 1 is by being set to it
The prism hole 11 on top and the 21 activity plug connection of prism of 2 bottom end of all-teeth screw, 3 screw thread of outer tube are rotatably connected in full tooth spiral shell
