In a preferred embodiment of the present invention, the fixed shaft and the top member are And the phase-retaining member is made of a rotating material. M285639 In a preferred embodiment of the present invention, the fixing member is a nut. In one embodiment, the outer peripheral surface of the fixing member has a hexagonal shape. In a preferred embodiment of the present invention, the first shaft portion has two sides, and the inner circumference of the magnetic ring has two and the first shaft. The side surface of the portion corresponds to the side surface, whereby the magnetic ring does not rotate in place when the magnetic ring is sleeved on the first shaft portion. In a preferred embodiment of the present invention, the pressing member is The outer peripheral surface has two sides corresponding to the sides of the magnetic ring, so that the pressing member can be embedded in the inner circumferential surface of the magnetic ring. [Embodiment] FIG. The structure and function of the present invention are described in detail; the drawings are briefly described as follows: The first figure is a front view of a preferred embodiment of the present invention; the second figure is taken along line 2-2 in the first figure. A cross-sectional view of the line; the second drawing is a schematic view of a combination of a preferred embodiment of the present invention. The fourth drawing is a side view of the fourth embodiment of the fixed axis of the fixed shaft provided by the present invention. FIG. 6 is a front view of the magnetic ring provided by a preferred embodiment of the present invention. Figure 8 is a side view of the second embodiment; the eighth figure is a front view of the pressing member provided by the preferred embodiment of the present invention; the ninth figure is a side view of the eighth figure; A front view of the fastener provided by the example; and 5 is a side view of the tenth diagram. Referring to the first to third figures, a non-contact transmission unit (10) according to a preferred embodiment of the present invention includes a fixed shaft (20), a magnetic ring (30), and a pressing member (40). ), as well as a fixture (50). As shown in the fourth and fifth figures, the fixed shaft (2〇) is made of a plastic material, the fixed shaft (2〇) has a substantially circular base portion (22), and a base portion (22) a first shaft portion (24) integrally extended, a second shaft portion (26) extending from the first shaft portion (24) body L, and a second shaft portion (26) a third shaft portion (28) extending integrally, wherein the first shaft portion (24) has two mutually parallel sides (242), and the second shaft portion (26) is obliquely from the first shaft portion ( 24) Extending @出, such that the outer peripheral surface of the second shaft portion (26) forms a slope (262)' and the outer peripheral surface of the third shaft portion (28) has a thread. As shown in the sixth and seventh figures, the magnetic ring (3〇) is sleeved on the first shaft portion (24) and the second shaft portion (26), and one of the magnetic rings (3〇) The side system abuts against the base portion (22), the outer circumference of the magnetic ring (30) is circular, and the inner circumference 2 has two sides corresponding to the side surface (242) of the first shaft portion (24). The side surface (32), when the magnetic ring (30) is sleeved on the first shaft portion (24), the magnetic ring (30) can be fixed to the first shaft portion (24) without in situ Rotating, in addition, when the magnetic ring (30) is sleeved on the second shaft portion (26), the inner circumferential surface of the magnetic ring (3〇) forms an inlay with the outer circumferential surface of the distal first shaft portion (26). Slot (34). 7 M285639 As shown in the eighth and ninth figures, the pressing member (40) is made of a plastic material, and the pressing member (40) is sleeved on the second shaft portion (26) and embedded. Provided in the recessed groove (34), the outer peripheral surface (42) of the pressing member (40) has two sides (422) corresponding to the side faces (32) of the magnetic ring (30), the pressing member ( The inner surface 5 (44) of the inner circumference is inclined, and the inclined direction of the inner circumferential surface (44) of the pressing member (40) is inclined to the inclined surface (262) of the second shaft portion (26). The inclination direction is the same, so that when the distal pressing member (40) is embedded in the recessed groove (34), the inner circumferential surface φ (44) of the pressing member (4) abuts against the second shaft portion ( 26) a bevel (262), in addition, one side of the pressing member (40) protrudes from the magnetic ring (3〇), and the pressing member (4〇) protrudes from the magnetic ring (30) One side has a first tooth portion (46). As shown in the tenth and eleventh figures, the fixing member (5〇) is a nut made of a plastic material, and the outer surface of the fixing member (50) is hexagonal, and the fixing member (50) The inner peripheral surface has a thread corresponding to the outer peripheral surface of the third shaft portion (28) such that the fixing member (50) can be screwed to the third shaft portion (28), and further, the fixing member (5〇) having a second φ tooth portion (52) on one side of the pressing member (40), the second tooth portion (52) being engageable with the first tooth portion (46) such that the The fixing member (50) can abut the pressing member (40). When the user wants to combine the non-contact transmission unit (1〇) provided by the creation, as shown in the third figure, the magnetic ring (3〇) is first set on the fixed shaft (2〇), 2〇 One side of the magnetic ring (30) is abutted against the base portion (22), and then the pressing member (40) is embedded in the recessed groove along the outer peripheral surface of the second shaft portion (26). 4) inside, at this time, the pressing member (40) has one side of the first tooth portion (46) protruding from the magnetic ring (30), and then the fixing member (5〇) is screwed and locked. The third shaft portion (28) is such that the second tooth portion (52) is fitted to the first tooth portion (46), 8 M285639, so that the fixing member (50) can abut the pressing member (40). ), in this way, the non-contact transmission unit (1〇) provided by the present invention is combined; since the fixed shaft (20), the pressing member (40), and the fixing member (5〇) are Made of a plastic material, when the fixing member (5〇) is locked to the third shaft portion (28), the fixing member 5 (50) and the pressing member (40) are not easily generated by friction. The particles affecting the air quality, in addition, the pressing member (4〇) is fastened by the top of the fixing member (5〇) The magnetic ring (3〇) is such that the magnetic ring (3〇) is fixed to the fixed shaft (2〇), and the magnetic ring (30) is not easily broken due to the locking member (5〇) being too tight. . 0 Therefore, the non-contact transmission unit (1〇) provided by this creation is not easy to affect the quality of the air, and the magnetic ring (30) is not easily damaged.
