[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the embodiment of the present invention provides a control cable stranding device, comprising: a base plate 1, a stranding assembly 2 and a tensioning assembly 3 are arranged on the top of the base plate 1; the stranding assembly 2 comprises a fixing plate 201 mounted on the base plate 1, the outer wall of the fixing plate 201 is fixedly equipped with a motor 1 202 providing a driving force, the end of the output shaft of the motor 1 202 is fixedly equipped with a rotating shaft 203, an inner cavity 204 is opened inside the rotating shaft 203, the inner wall of the inner cavity 204 is fixedly equipped with a motor 2 205 providing a driving force, the end of the output shaft of the motor 2 205 is fixedly equipped with a bidirectional threaded rod 206, the outer wall of the bidirectional threaded rod 206 is threadedly connected with a moving ring 207, and the moving ring 207 is fixedly equipped with a moving ring 207. The outer wall of the connecting rod 208 is rotatably connected to the connecting rod 208, and the connecting rod 208 passes through the rotating shaft 203. The end of the connecting rod 208 away from the movable ring 207 is rotatably connected to the annular plate 209. The bottom of the annular plate 209 is rotatably connected to the rotating rod 210. The end of the rotating rod 210 away from the annular plate 209 is rotatably connected to the rotating shaft 203. There are four groups of connecting rods 208, annular plates 209 and rotating rods 210, and the four groups of connecting rods 208, annular plates 209 and rotating rods 210 are evenly distributed on the circumferential side of the rotating shaft 203. By limiting the number and position of the connecting rods 208, annular plates 209 and rotating rods 210, it is beneficial to improve the tension of the winding when the control cable is twisted.

[0027] like Figure 1 and Figure 3 As shown, the tensioning assembly 3 includes a fixing frame 301 installed on the top of the base plate 1, the top of the inner wall of the fixing frame 301 is fixedly equipped with a spring 302, the inner wall of the fixing frame 301 is fixedly equipped with a sleeve 303, the inner wall of the sleeve 303 is slidably connected to the moving rod 304, the bottom ends of the spring 302 and the moving rod 304 are both fixedly equipped with a connecting plate 305, the inner wall of the connecting plate 305 is rotatably connected to the roller 306, the control cable is attached to the outer wall of the roller 306, and the spring 302 pushes the connecting plate 305 and the roller 306 to press against the control cable, thereby stretching the control cable, thereby improving the winding effect of the control cable.

[0028] like Figure 1 and Figure 2 As shown, a groove 4 is provided on the outer wall of the annular plate 209, and an anti-slip pad 5 is fixedly installed on the inner wall of the groove 4.
