A guide wheel 12 is installed on both sides of the top of the support 1. The bottom end of the outside of the support 1 is welded with a limit plate 2, and the interior of the support 1 below the limit plate 2 is opened. The wire taking-up hole 20 and the support plates 21 are installed on both sides of the bottom of the limit plate 2, and a machine shaft 23 is connected between the support plates 21. The machine shaft 23 synchronously penetrates the support plate 21. A wire taking-up drum 24 is sleeved on the outside of the machine shaft 23.
