The protective shell 11 is connected to the pelletizing blade 12 through the positioning column 14, and the other end of the positioning column 14 is connected to the pull ring 15. A buffer pad 16 is provided below the groove. The hydraulic rod 10 extends and drives the protective shell 11 downward, so that the pelletizing blade 12 pelletizes the plastic rod. When the pelletizing blade 12 is severely worn, the pelletizing blade 12 falls onto the buffer pad 16 driven by the hydraulic rod 10, and the pull ring 15 is pulled, so that the positioning column 14 is separated from the pelletizing blade 12 under the compression of the first spring 13, so that a new blade is replaced, making it more convenient to use.

[0020] The fixing mechanism 6 includes a servo motor 17, a screw rod 18, a slider 19, a second spring 20, a first sleeve 21 and a second sleeve 22. Slide grooves are provided on both sides of the inner wall of the support frame 2, and a servo motor 17 is provided in the slide groove. The output shaft of the servo motor 17 is connected to the screw rod 18. A slider 19 is provided on the screw rod 18. One side of the slider 19 is connected to the fixing plate 4.
