[0037] The utility model has the advantage of supporting the extruded cable by arranging the upright column 301, the connecting column 302 and the arc-shaped supporting bar 303, so that the cable at the extrusion end of the stranding machine is kept horizontal, thereby solving the problem that the cable extruded by the stranding machine has no support at the extrusion position, the cable bends down due to gravity, and the cable will bend and crush the extrusion end of the stranding machine, thus affecting the extrusion of the cable.

[0038] Specifically, the bottom end of the connecting column 302 is rotatably connected to the top end of the column 301 via a rotating shaft; the arc-shaped support bar 303 switches between horizontal and vertical directions; when in use, the arc-shaped support bar 303 is facing the extrusion end of the stranding machine, and when not in use, the arc-shaped support bar 303 is rotated perpendicular to the extrusion end of the stranding machine, and the arc-shaped support bar 303 does not extend out of the way.

[0039] Furthermore, the connection column 302 and the column 301 are positioned and matched with each other through a positioning assembly 304;
