In addition, as shown in Figure 7, when the peripheral edge of the second disk surface 340b is completely or substantially flush with the peripheral edge of the first disk surface 340a, an airtight tape can be used as a seal on the peripheral edge of the disk surface 340 to cover the first disk surface. The gap between 340a and the second disk surface 340b. Alternatively, in other unillustrated embodiments, the peripheral edge of the second disk surface may also protrude from the peripheral edge of the first disk surface to form a flat disk surface with a larger size.

Fig. 8 is a longitudinal sectional view of various suction holes according to an embodiment of the present invention, and Fig. 9 is a plan view of various suction holes according to an embodiment of the present invention. In short, in order to respond to the various ring styles on the market, the suction holes can have various shapes to provide the best adsorption effect on the ring. For example, as shown in Figure 8-1, the disk surface in this embodiment may be an integrally formed disk surface, and the suction hole may be a straight hole, and the cross-sectional shape of the suction hole may be It is a circle, oval, egg, elongated, square, rectangular, diamond, trapezoid or other polygon as shown in Figure 9. Alternatively, in the embodiment shown in Figs. 8-2 to 8-4, the suction holes can also be a combination of two or more suction holes with different cross-sectional sizes and/or shapes, or That is, the upper opening and the lower opening of the suction hole may have different cross-sectional sizes and/or shapes.

In more detail, as shown in Fig. 8-2, the suction holes in this embodiment are, for example, after two drills of two different sizes are drilled twice to form two sections of coaxial circular holes with different diameters.

The above layers are combined with disk surfaces, and these disk surfaces respectively have suction holes of different sizes and/or shapes. For example, for the embodiment shown in Fig. 8-2, a disk surface with a large circular hole and a disk surface with a small circular hole may be combined. In addition, additional processing methods can be used to change the shape of the suction hole on the bearing surface according to the shape and contour of the ring, so as to improve the vacuum suction force of the suction hole on the ring.

Figure 10 is a schematic diagram showing various combinations of suction holes and notches according to the present invention. In more detail, as shown in Figure 10-1, in a preferred embodiment of the present invention, the inhalation The hole 142 is in the shape of a round hole, and the notch 146 is a single triangular cone-shaped notch that is machined outwards and downwards from the suction hole 142 on the bearing surface 144 by the tool, and its depth is less than The thickness of the disk surface 140. However, in other similar embodiments, the depth of the notch may also be equal to the thickness of the disk surface, that is, the notch will penetrate the disk surface. Alternatively, in other embodiments, a plurality of notches may be formed on the disk surface, and the notches may be arranged radially or asymmetrically around the center of the suction hole.

For example, in Fig. 10-2, there are two triangular pyramid-shaped notches 146 formed in a symmetrical arrangement around the suction holes 142. Furthermore, in Figure 10-3, for example, an elongated hole is formed at one end of the suction hole 142 adjacent to the supporting surface, and the width of the elongated hole is, for example, smaller than the diameter of the suction hole. In addition, in FIG. 10-4, for example, a plurality of notches 146 with different shapes and sizes are arranged asymmetrically around the suction hole 142. These notches can make the suction hole closer to the surface of the ring and help improve the vacuum suction force of the suction hole on the ring.
