The hole 309c is distributed to partially expose the magnet 34c. Of course, the shrapnel and the movable assembly should be correspondingly shaped to match the fixed assembly 30c.
當然，該置磁部307c亦可由固定體32c之內壁向其外壁凹陷形成 。 Of course, the magnetic portion 307c may also be recessed from the inner wall of the fixing body 32c toward the outer wall thereof. .
請參閱圖5，其為本發明第四實施例所提供之固定裝組30d，該固定裝組30d具有一固定體32d及四個裝設於固定體32d上之圓弧形磁鐵34d，該固定體32d為一具有與側壁一體成型之底板322d之筒狀結構，其具有一圓角形之環狀之第一端面35d及與該第一端面35d相對之第二端面36d，該第一端面35d之位於四個圓角處之部分端面向該第二端面36d之位於四個圓角處之部分端面凹陷形成四個圓弧形之置磁部307d，該置磁部307d用來收容該磁鐵34d，且該置磁部307d之形狀與該磁鐵34d之形狀相匹配，以使該磁鐵34d緊密地收容於該置磁部307d中，該固定體32d之四個圓角處之內壁上還分別開設有孔309d，以使磁鐵34d部分露出。當然，彈片及活動裝組應相應之變為與固定裝組30d相匹配之形狀。 Referring to FIG. 5, a fixed assembly 30d according to a fourth embodiment of the present invention has a fixed body 32d and four arc-shaped magnets 34d mounted on the fixed body 32d. The body 32d is a cylindrical structure having a bottom plate 322d integrally formed with the side wall, and has a rounded first end surface 35d and a second end surface 36d opposite to the first end surface 35d. The first end surface 35d is located a portion of the four rounded corners facing the second end surface 36d is recessed at a portion of the four rounded corners to form four arc-shaped magnetic portions 307d for receiving the magnet 34d. The shape of the magnetic portion 307d is matched with the shape of the magnet 34d so that the magnet 34d is tightly received in the magnetic portion 307d, and the inner walls of the four rounded portions of the fixed body 32d are respectively opened. The hole 309d is such that the magnet 34d is partially exposed. Of course, the shrapnel and the movable assembly should be correspondingly shaped to match the fixed assembly 30d.
當然，該置磁部307d亦可由固定體32d之內壁向其外壁凹陷形成。 Of course, the magnetic portion 307d may be formed by recessing the inner wall of the fixed body 32d toward the outer wall thereof.
可理解，該磁鐵之個數亦可為五個、六個或更多個，不限於本實施例，只要該固定體設有個數與磁鐵個數相同之置磁部即可。 It can be understood that the number of the magnets may be five, six or more, and is not limited to the embodiment, as long as the fixed body is provided with a magnetic portion having the same number as the number of magnets.
當然，該固定體亦可為三角形、四邊形、五邊形、六邊形等其他幾何結構。 Of course, the fixing body may also be other geometric structures such as a triangle, a quadrangle, a pentagon, a hexagon, and the like.
當然，若該固定體由磁鐵可吸附之材料(例如鎳鐵、不銹鐵或鍍鋅鐵等)製成，則，此時可將磁鐵直接吸附於固定體之內壁上。 Of course, if the fixed body is made of a material that the magnet can adsorb (for example, ferronickel, stainless iron, or galvanized iron, etc.), the magnet can be directly adsorbed on the inner wall of the fixed body.
綜上所述，本發明確已符合發明專利之要件，遂依法提出專利申請。惟，以上所述者僅為本發明之較佳實施方式，自不能以此限 制本案之申請專利範圍。舉凡熟悉本案技藝之人士爰依本發明之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。 In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and cannot be limited thereto. The scope of the patent application for this case.
