Detailed Description

For the purpose of further illustrating the various embodiments, the present utility model provides the accompanying drawings, which are a part of the disclosure of the present utility model, and which are mainly used to illustrate the embodiments and, together with the description, serve to explain the principles of the embodiments, and with reference to these descriptions, one skilled in the art will recognize other possible implementations and advantages of the present utility model, wherein elements are not drawn to scale, and like reference numerals are generally used to designate like elements.

According to an embodiment of the present utility model, there is provided a grounding copper bar for ductile use.

Embodiment one:

as shown in fig. 1, a grounding copper rod capable of being used in an extending mode comprises a copper-clad steel rod, wherein the copper-clad steel rod is formed by a first rod body 1 and a second rod body 2, the second rod body 2 is inserted into the first rod body 1, a clamping hole 3 is formed in the left side of the upper end of the first rod body 1, a limiting groove 4 is formed in the upper end of the second rod body 2, a limiting clamping rod 5 is arranged in the limiting groove 4, a spring 6 is fixedly connected to the inner end of the limiting clamping rod 5, the outer end of the limiting clamping rod 5 is clamped into the clamping hole 3, an external thread groove 7 is formed in the outer wall of the upper portion of the second rod body 2, and an internal thread groove 8 is formed in the inner wall of the bottom of the first rod body 1.

Embodiment two:

the top end of the first rod body 1 is provided with a wire connecting plate 9;

the other end of the spring 6 is fixedly connected to the inner wall of the limit groove 4;

the external thread groove 7 is matched with the internal thread groove 8, so that the second rod body 2 can be screwed with the first rod body 1 after being extended;

the working principle of the utility model is as follows:

when the length of the grounding copper rod needs to be prolonged, the limiting clamping rod 5 is pressed firstly, the limiting clamping rod 5 is pressed into the first rod body 1, then the second rod body 2 is pulled out from the first rod body 1, and when the second rod body 2 reaches the inner bottom of the first rod body 1, the first rod body 1 and the second rod body 2 are screwed up through the external thread groove 7 and the internal thread groove 8;
