接著，以下將對壓體20進行說明。壓體20係包含有一樞接 部21以及一抵持部22，其中，壓體20中的一部或全部係大致上 的由一線材撓曲而成。舉例來說，於本具體實施例t，樞接部21 以及柢持部22係由一線材一體撓曲而成。更明確的說，壓體2〇 之形狀係大致上的包含有兩個撓成小寫字母b字狀之子結構配合 一分別連接於子結構二末端之一連接部而形成，如圖二所繪述。 除此之外，有鑑壓體20需要一定程度的彈性變形能力以及剛性， 故=，在實際應用時’壓體2〇之材質建議為一粗細適中的高強度 金屬線體，如鋼琴線，即為一例。 。再者，相對應於基座1〇的第一部件n，本創作的樞接部21 ，樞接於第一部件11來使該壓體20得以該第一部件1丨為支點作 旋轉。以圖二為例，其壓體20係樞接於複數個第一部件u ^， ，，，其不以此為限，視壓體2〇設計的不同，每個壓體2〇得僅 糟早一個第一部伴Π來樞接於基座1〇之表面，如圖三所繪述。Next, the pressing body 20 will be described below. The pressing body 20 includes a pivoting portion 21 and a resisting portion 22, wherein one or all of the pressing bodies 20 are substantially bent by a wire. For example, in the specific embodiment t, the pivoting portion 21 and the holding portion 22 are integrally bent by a wire. More specifically, the shape of the compact 2 is substantially formed by two substructures that are bent into a lowercase b-shape, and are respectively connected to one of the two ends of the substructure, as shown in FIG. . In addition, the pressure-sensing body 20 needs a certain degree of elastic deformation ability and rigidity, so = in practical application, the material of the pressing body 2 is recommended to be a medium-strength high-strength metal wire body, such as a piano wire. This is an example. . Furthermore, the pivoting portion 21 of the present invention is pivotally connected to the first member 11 corresponding to the first member n of the base 1 to rotate the pressing body 20 by the first member 1 丨 as a fulcrum. Taking FIG. 2 as an example, the pressing body 20 is pivotally connected to the plurality of first parts u ^, ,, which are not limited thereto, and each pressing body 2 is only badly different depending on the design of the pressing body 2〇. The first part of the mate is pivoted to the surface of the pedestal 1 ,, as depicted in Figure 3.

More specifically, in the case of Fig. 2, the pressing portion 22 of the pressing body exerts a vertical direction of pressure on the pair 3 to press the target 3 against the horizontal surface S1 of the base 10. 3 j note ί is the resisting part 22 mentioned above, not directly pressed against the target object 矣 1 2 . For example, the designer has to provide an interface structure 25 at either end of the resisting portion 22 with respect to the direction of the pressing body to adjust the gap between the resisting portion 22 and the target object 3: The fixing effect of 2G on the target 3 is shown in Fig. 4. Further, the abutting portion 22 of the pressing body 20 is formed of at least one resisting structure 221. Referring to FIG. 2 again, in this embodiment, the resisting portion of the pressing body 2〇 22 9 M442680 is fixed: ΐ : : The four A series depicts the object of the creation, the solid state, the i ΐ embodiment in the lock solid state Schematic diagram of F1.

Escape a silver f-frequency remuneration towel, the base 10 and the pressing body 2G have further steps to include the ί ίίίί 13 and the yucking holding portion 24. When in the storage state F3, the pressure damper 24 is held against the third member 13 at a temporary position or at the surface of the susceptor 1 , as depicted in Fig. 4B. τ - 二ΐ Γ f and the design depicted in Fig. 4, for example, the third component 13 is formed or ί ϊ ί ΐ on the surface S2 from the vertical surface S2 to the side of the compact 20, while the card is _ The holding portion 24 is extended by the pivoting portion 21: ^More precisely, in the specific embodiment, the pressing body 2 Π + 21 is extended outward by the box of 11 boxes, and the wing is formed. The holding portion 24. Here, the aforementioned holding portion 24 is surrounded by the second member 13 to hold the position therein. ^ The width of the width is slightly wider than the width of the foregoing, and accordingly, the subtraction portion is -=3 13 22 1〇S2^. It should be noted that the holding portion 24 and the third member 13 are not allowed to be opened.
