[0025] Reference Figure 2-Figure 3 The triangle plate 45 is hinged on the inner wall of one side of the support frame 1 close to the spur gear 44, and the movable rod 46 is clamped on the bottom outer wall of the triangle plate 45. The end of the movable rod 46 away from the triangle plate 45 is fixedly connected with a pull handle 47. The movable rod 46 cooperates with the pull handle 47 to pull out and plug in the movable rod 46. The end of the rotating column 2 away from the support frame 1 is fixedly connected with an adjusting disk 48. The outer walls on both sides of the dust cover 41 are fixedly connected with transparent glass 49. The transparent glass 49 is provided to facilitate personnel to penetrate the use of the internal steel strand. The top inner wall of the dust cover 41 is hinged with a sealing cover 410. The rotating column 2 penetrates the inner wall of one side of the support frame 1. The rotating column 2 is rotatably connected to the outer wall of one side of the support frame 1 through a bearing, and the bottom outer wall of the support frame 1 is fixedly connected with a base 3.

[0026] Reference Figure 3-Figure 4 The auxiliary mechanism 5 includes a threaded groove 51, which is provided on an inner wall of one side of the dust cover 41. The inner circle of the threaded groove 51 is threadedly connected with a threaded column 52. An opening and closing cover 53 is hinged on the top inner wall of the threaded column 52. After the opening and closing cover 53 is opened, the sponge 54 can be conveniently disassembled and replaced. A sponge 54 is fixedly connected to an inner wall of one side of the opening and closing cover 53. The surface of the steel strand is wiped and cleaned in real time by setting the sponge 54. There are two sponges 54. The two sponges 54 are respectively clamped on the inner wall of one side of the threaded column 52 and the opening and closing cover 53. The opening and closing cover 53 is clamped on the side inner wall of the threaded groove 51.

[0027] Working principle: the finished steel strand is placed on the steel strand drum 43, and then one end of the steel strand is passed through the sponge 54 in the threaded column 52. Then the staff pulls the steel strand to release the wire. At the same time, it is blocked by the dust cover 41 and the sealing cover 410 during the rainy season and when there is a lot of dust. When the steel strand is cut, the excess steel strand will rebound and cause the steel strand drum 43 to rotate. The rotation of the steel strand drum 43 drives the rotating column 2 to rotate. The rotating column 2 rotates the spur gear 44 to rotate instantaneously. When the spur gear 44 rotates instantaneously, it collides with the triangle plate 45 to limit the engagement and prevent rebound. At the same time, when releasing the wire, the steel strand is wiped clean by the sponge 54. After long-term use, it is separated from the threaded groove 51 by rotating the threaded column 52, and then the opening and closing cover 53 is opened to conveniently disassemble and replace the sponge 54.
