and 5: the steps are repeated, so that the sewing work can be carried out on the positions to be sewn of the automobile cushion one by one.

When the automobile cushion sewing work needs to be carried out, the discharging frame 9 is initially positioned on one side of the upper surface of the operating platform 1, the reset spring 23 is in a stretching and force-storing state, the clamping rod 27 is positioned outside the clamping groove 26, an operator firstly places the automobile cushion to be sewn inside the discharging frame 9 and then pushes the discharging frame 9 towards the direction of the clamping groove 10, the discharging frame 9 drives the linkage block 22 to move, the linkage block 22 and the guide rod 21 extrude the connecting sleeve 6, so that the connecting sleeve 6 slides inside the through groove 5, the connecting sleeve 6 drives the sliding block 8 to slide along the inside of the sliding groove 7, when the discharging frame 9 completely moves to the port of the clamping groove 10, the reset spring 23 drives the linkage block 22 to descend, the linkage block 22 drives the clamping rod 27 to be clamped into the inside of the clamping groove 26, so as to limit the discharging frame 9 to shake, at this time, the position of the automobile cushion to be sewn is aligned to the lower part of the sewing needle, finally, an operator operates the machine head 4 to drive the sewing machine head to sew the side of the automobile cushion.

When the sewing position of the automobile cushion needs to be adjusted, an operator firstly pulls the handle 14 towards the outer side of the operating platform 1, the handle 14 drives the positioning rod 29 to gradually slide out from the inside of the positioning groove 30, then the operator presses the handle 14, the handle 14 presses one end of the movable plate 13 to descend, the movable plate 13 drives the connecting rod 17 to rotate in the connecting bearing 16, the other end of the movable plate 13 is lifted and ascends in an arc shape, the movable plate 13 drives the other two connecting rods 17 to rotate in the other two connecting bearings 16 and ascend in the arc shape, the connecting rod 17 provides an upward acting force for the supporting rod 19 and is limited by the circular groove, the supporting rod 19 can only ascend vertically, the supporting rod 19 can lift up the guide rod 21 after sliding out from the inside of the circular groove, the guide rod 21 lifts up the linkage block 22 under the force, and the linkage block 22 lifts up the discharging frame 9 to slide out from the inside of the clamping groove 10, the guide rod 21 can also drive the reset spring 23 to extend and accumulate force, meanwhile, the linkage block 22 drives the clamping rod 27 to slide out of the clamping groove 26, the discharging frame 9 is not limited at the moment, and finally, an operator pushes the discharging frame 9 to rotate ninety degrees, so that the position of the automobile seat cushion to be sewn can be adjusted to the position below the sewing needle.

After the position of the automobile cushion is adjusted, an operator releases the pressing force on the handle 14, then under the action of the resilience force of the return spring 23, the linkage block 22 drives the clamping rod 27 to descend synchronously until the lower surface of the linkage block 22 and the upper surface of the connecting sleeve 6 are attached to each other, the clamping rod 27 stops after being clamped into the clamping groove 26, the linkage block 22 drives the guide rod 21 to press the support rod 19 to descend along the inside of the circular groove, the support rod 19 descends while driving the connecting rod 17 to press the movable plate 13, then one end of the movable plate 13 descends, the movable plate 13 drives the connecting rod 17 to rotate inside the connecting bearing 16, so that the other end of the movable plate 13 returns to the initial position, finally, the operator pushes the handle 14 towards the operation table 1, the handle 14 drives the positioning rod 29 to be clamped into the inside of the positioning groove 30, and finally the movable plate 13 is fixed, avoided external force factor to lead to the phenomenon emergence that fly leaf 13 rocked, the operator can move aircraft nose 4 once more after the adjustment finishes and drive the sewing needle and carry out the sewing work, repeat above-mentioned step alright with treating the position of sewing up to car cushion one by one and sew up the work.
