A connecting arm 27 is fixedly installed on the outer wall of the center plate 28, and a slider 26 is fixedly installed on one end of the connecting arm 27 away from the center plate 28. The slider 26 is slidably connected to the outer wall of the alloy arm 24. An elastic component 281 is fixedly installed on the right side of the center plate 28. The right side of the elastic component 281 is fixedly connected to the left side of the fixed circular plate 25. The end of the towing rod 29 is connected to an external object. Before the wire rope tends to be straightened during the towing process, the center plate 28 will slide on the outer wall of the alloy arm 24 through the connecting arm 27 and the slider 26, and compress the elastic component 281 at the same time. The elastic deformation generated by the elastic component 281 can achieve the function of buffering the instantaneous force of the wire rope, thereby increasing safety.

[0022] As an implementation method in this embodiment, Figure 2 As shown, the fixed circular plate 23 is fixedly installed on the right side of the positioning circular seat 21, and an ear plate 22 is welded on the outer wall of the positioning circular seat 21.

The left side of the elastic component 282 is fixedly connected to the right side of the fixed circular plate 23, and the ear plate 22 is installed on the rear anti-collision beam 13 by a plurality of bolts to increase the stability of the installation.

If it is inconvenient for the user to perform the connection operation, the No. 1 threaded rod 292 is unscrewed from the inside of the threaded groove 291, and then screwed into the No. 2 threaded rod 294, and then the end of the wire rope is passed through the inner cavity of the circular groove 296, and then through the inner cavity of the square groove 297, and then the clamping bolt 299 is manually rotated to drive the anti-slip pad 2 to move and cooperate with the anti-slip pad 1 298 to position the wire rope. When the limiting rod rotates the clamping bolt 299, it limits the translation of the anti-slip pad 2.

[0024] Working principle: The external object is connected to the end of the towing rod 29 through a steel wire rope. Before the steel wire rope tends to be straightened during the towing process, the median plate 28 will slide on the outer wall of the alloy arm 24 through the connecting arm 27 and the slider 26, and at the same time, the elastic component 1 281 is compressed and the elastic component 2 282 is stretched. The elastic deformation generated by the elastic component 1 281 and the elastic component 2 282 can achieve the function of buffering the instantaneous force on the steel wire rope.
