[0022] The present embodiment provides a screw assembly for a juicer, comprising a screw 1 that is in direct contact with fruits and vegetables during squeezing, the screw 1 comprising a screw body 2, and a stepped portion 4 (shaped like a circular shaft) integral with the screw body 2. The stepped portion 4 has a height of A, and eight spiral threads 5 are provided from the bottom surface 3 of the screw to the stepped portion 4. The highest spiral thread 5 (the one closest to the top surface 6 of the screw) has a height of B from its highest point to the top surface 6 of the screw. In the present embodiment, B is two-thirds of A. A central rotating rod 7 is tightly fitted inside the screw 1, and a screw seal 8, a metal screw blade 9, and a blade fixing member 10 are sequentially installed on the top of the central rotating rod 7 from bottom to top. Finally, these three parts are fixed to the central rotating rod 7 with a fixing screw 11.

[0023] In the embodiments of the present invention, please refer to Figure 4 The outer diameters of the stepped portion 4, the screw seal 8 and the metal screw blade 9 are equal, and after assembly, the outer circumferences of the three are in the shape of a smooth circular shaft without any concave or convex gaps.

[0024] In the embodiments of the present invention, please refer to Figure 3 The angle C between the outer side of the spiral thread 5 and the horizontal plane is 82 degrees. This structural angle allows the screw 1 to tilt downward as it moves radially outward, which can better squeeze out the juice of fruits and vegetables.

[0025] In the embodiments of the present invention, please refer to Figure 4 The top of the central rotating rod 7 is shaped like a square stepped shaft 12, and the inner holes of the screw seal 8, the metal screw blade 9, and the blade fixing member 10 are all square holes. This square hole-shaft design, because it is limited in the X and Y directions, only needs to tighten the fixing screw 11 in the Z direction (i.e., the vertical direction) to completely fix it.

[0026] The beneficial effects of this utility model are as follows: the metal screw blade 9 is detachable, with a large spacing between the metal screw blade 9 and the spiral thread 5 on the screw 1. Moreover, the outer periphery of the stepped portion 4, the outer periphery of the screw seal 8, and the outer periphery of the metal screw blade 9, when assembled, presents a smooth, circular shaft-like outer periphery, with no concave or convex gaps. This novel structure prevents fruit and vegetable debris from entering the gap between the screw top surface 6 and the metal screw blade 9 due to rotation when cutting fruits and vegetables, eliminating the need for cleaning residue and disassembly of parts, and providing a good user experience.
