[0007] Further, it further comprises a top rod, and two top rods are fixedly connected to the fixed frame.
[0008] Further, the top rod is provided with an inclined surface at the bottom.
[0009] The utility model discloses a beneficial effect is: 1, the cutting line knife will contact with the roof in the process of descending, and the roof will extrude the cutting line knife, make the cutting line knife remove the direction of the roof, one pressure spring is compressed, and the cutting line knife is cut to the yarn through the mode of transverse movement, make the yarn cutting port more level, improve the cutting quality.
[0010] 2, in the process that the pressing plate is inserted into the sliding sleeve rod, the sliding sleeve rod will be extruded by the jacking rod, so that the two sliding sleeve rods will move away from each other, the reset spring is stretched, and the sliding sleeve rod is reset, so that the sliding sleeve rod and the jacking rod are separated, and the reset spring resets the two sliding sleeve rods. Through the mode, after the pressing plate presses the yarn, the sliding sleeve rod will drive the two pressing plates to move away from each other, so that the yarn can keep straight, so that the cutting knife can cut the yarn more smoothly.
