[0002] Wood shredders are mainly used to crush wood and other timber to maximize their utilization value and reduce environmental pollution. They are one of the fastest, most ideal, and most affordable wood shredders available. Most existing wood shredders use crushing rollers as their crushing components, with wood crushing teeth welded to the rollers. Crushing is achieved through compression and rotation. However, under prolonged exposure to high rigidity and compression, the mechanical connections of the crushing teeth can loosen, leading to tooth loss. Furthermore, the crushing teeth are inconvenient to replace and install, thus limiting the crushing effect. Utility Model Content

The two ends of the secondary shaft 8 are respectively inserted into the secondary shaft end hole 11 and secondary shaft end hole 21. Both the outer edges of the secondary shaft end hole 11 and the secondary shaft end hole 21 are provided with a groove. An outer fixing pressure plate 14 is provided in the groove. Both ends of the secondary shaft 8 are fixed to the outer fixing pressure plate 14 by screws. In order to prevent the secondary shaft 8 from rotating, the secondary shaft end hole 21 is a limiting secondary shaft hole to prevent rotation.
