The root of cantilever 5 welds in the top of pivot 4, when pivot 4 rotated, drives cantilever 5 and uses the pivot as the centre of a circle in the horizontal plane internal rotation to make the free end of cantilever 5 rotate to the top of drawing the track.

As shown in fig. 3, the cantilever 5 is a hollow tubular structure, the diameter of the rotating arm 6 is matched with the inner diameter of the cantilever 5, and the rotating arm 6 extends into the cantilever 5 and can rotate in the cantilever 5. As shown in fig. 1 and 3, a raised mandril 10 is welded at the top of the root of the rotating arm 6, a horizontal limiting plate 11 is installed at the end part of the rail 1, the height of the limiting plate 11 is slightly lower than the top height of the mandril 10, before the free end of the cantilever 5 does not extend to the upper part of the traction track, the mandril 10 is positioned in front of the limiting plate 11, when the cantilever 5 needs to extend and the cantilever 5 rotates, the mandril 10 is pressed into the lower part of the limiting plate 11, the limiting plate 11 presses and pushes the mandril 10, and the mandril 10 drives the rotating arm 6 to rotate anticlockwise. The movable clamping plate 7 is an arc-shaped plate bent downwards, the movable clamping plate 7 is welded at the free end of the rotating arm 6, and when the rotating arm 6 rotates anticlockwise, the movable clamping plate 7 on the rotating arm 6 is lifted and opened to wait for feeding of the aluminum profile 18.

As shown in fig. 2 and 3, the free end of the cantilever 5 is provided with a movable hole 12 matching with the length of the movable clamp plate 7, the movable clamp plate 7 extends out of the cantilever 5 from the movable hole 12, and the root of the movable clamp plate 7 can rotate in the movable hole 12. The movable hole 12 provides a movable space for the rotation of the movable clamping plate 7, and the movable clamping plate 7 is limited in the length direction, so that the movable clamping plate 7 is prevented from freely sliding along the axial direction of the cantilever 5, and the stability of the action of the movable clamping plate 7 is ensured. In order to further prevent the movable clamping plate 7 from sliding in the length direction, a limiting sleeve 13 is installed at the root of the rotating arm 6, the limiting sleeve 13 can be fixedly connected with the root of the rotating arm 6 in a threaded mode, and the outer diameter of the limiting sleeve 13 is larger than or equal to that of the cantilever 5.

An upright supporting plate 15 is welded at the free end of the cantilever 5, and the fixed clamping plate 8 is horizontally welded on the supporting plate 15 and is positioned right below the movable clamping plate 7. When the free end of the cantilever 5 rotates to the position above the traction track, the front end of the aluminum profile 18 is conveyed to the fixed clamping plate 8 by the forming machine and is supported by the fixed clamping plate 8, the motor drives the tractor to leave the limiting plate 11, the ejector rod 10 on the rotating arm 6 loses the pressure of the limiting plate 11, the movable clamping plate 7 rotates clockwise and downwards under the action of gravity, and the movable clamping plate and the fixed clamping plate 8 clamp the aluminum profile 18 tightly.

As shown in fig. 2, a counterweight 14 is fixed at the bottom of the limiting sleeve 13, the counterweight 14 cooperates with the movable clamp plate 7 to pull the rotating arm 6 downwards, so that the rotating arm 6 is smoothly rotated and reset, and the movable clamp plate 7 reliably clamps the aluminum profile 18; the balancing weight 14 also strengthens the clamping force of the movable clamping plate 7 on the aluminum profile 18, and avoids the movable clamping plate 18 from shaking up and down.
