DETAILED DESCRIPTION

[0033] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments and drawings, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0034] Example 1: See Figure 1-Figure 4 The purpose of this embodiment is to provide a ground rod extraction auxiliary tool, which includes a tool body 1 and a connecting plate 2.

[0035] like Figure 1 , Figure 2 As shown, the tool body 1 is provided with a round rod-shaped handle 11, one end of the handle 11 is provided with a non-slip handle 16, and the other end of the handle 11 is fixedly provided with a fixing plate 12; the plate surface of the fixing plate 12 is parallel to the central axis of the handle 11; a clamping member 13 is fixedly provided on the side of the fixing plate 12 away from the handle 11; a connecting shaft 14 is vertically fixedly provided on the fixing plate 12, and the connecting shaft 14 extends to both sides of the fixing plate 12, and at the same time, the central axis of the connecting shaft 14 is perpendicular to the central axis of the handle 11.

[0036] The clamping member 13 is in the shape of a bent plate, and its upper part is gradually bent toward the handle 11. The bending part of the clamping member 13 gradually increases its distance from the connecting shaft 14 from bottom to top. A tooth surface 17 is fixedly provided on the side of the clamping member 13 away from the fixing plate 12. The tooth surface 17 is in an arc shape as a whole. A plurality of strip-shaped anti-skid teeth are provided on the tooth surface 17, and the anti-skid teeth are all parallel to the connecting shaft 14. At the same time, the distance between the anti-skid teeth and the connecting shaft 14 gradually increases.

[0037] A plurality of reinforcing ribs 15 are fixedly arranged on one side of the clamping member 13 close to the fixing plate 12 to improve the connection strength between the clamping member 13 and the fixing plate 12 and to strengthen the clamping member 13 to prevent deformation. The reinforcing ribs 15 are distributed on both sides of the fixing plate 12.

[0038] like Figure 3 As shown, a plurality of connection holes 21 are provided on the connection plate 2 , and the diameter of the connection hole 21 is slightly larger than the outer diameter of the connection shaft 14 , so that the connection shaft 14 can be movably inserted into the connection hole 21 .

[0039] When the utility model is used, two tool bodies 1 are horizontally placed on both sides of the ground rod 3 (can be placed on the ground), so that the clamping piece 13 fits the ground rod 3 as much as possible; then two connecting plates 2 are used, and the connecting plates 2 on each side are fitted with suitable connecting holes 21 on the connecting shafts 14 of the two tool bodies 1; then the handle end of the grip 11 is lifted, and the clamping piece 13 will gradually clamp the ground rod 3 (such as the ground rod 3) due to the limit of the connecting plate 2. Figure 4 ); Finally, one person holds the two anti-slip handles 16 and lifts them upward, or two people hold the anti-slip handles 16 and lift them upward to pull out the ground rod 3.

[0040] This embodiment can achieve a firm clamping of the ground rod 3 by providing the tooth surface 17. To further improve the anti-skid performance of the tooth surface 17, the upper side surface of the anti-skid teeth is perpendicular to the clamping member 13, that is, the cross-section of the anti-skid teeth is a right triangle, and the right angle is located at the upper side near the clamping member 13.

[0041] The present embodiment may not be provided with the tooth surface 17, and when the anti-slip handle 16 is held and lifted upward with force, the clamping member 13 can also clamp the grounding rod 3, thereby realizing the extraction of the grounding rod 3. The structure with the tooth surface 17 is suitable for the extraction of steel grounding rods, and the structure without the tooth surface 17 is suitable for the extraction of grounding rods made of softer materials such as copper.

[0042] Example 2: See Figure 5-Figure 6 The ground rod extraction auxiliary tool provided in this embodiment has the following improvements compared with the embodiment 1:

[0043] The clamping member 13 includes a first clamping portion 131 and a second clamping portion 132 located on both sides of the fixing plate 12. The first clamping portion 131 and the second clamping portion 132 are both inclined away from the fixing plate 12, and the angle between the first clamping portion 131 and the second clamping portion 132 is 90°-120°.

[0044] like Figure 6 As shown, the grounding rod 3 can be clamped between the first clamping portion 131 and the second clamping portion 132 . Therefore, the present embodiment uses four tooth surfaces 17 to clamp the grounding rod 3 , so that the present invention clamps the grounding rod 3 more firmly.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
