The safety hanger 1 〇〇 mainly comprises a hemispherical orphan segment 11 which is worn in the arc a connecting portion 12 at the center of the segment, a supporting pin disposed through the curved portion U and the connecting portion 12, and a bolt 14 screwed to the curved portion and the connecting portion 12, the supporting pin η is used to strengthen the bending of the connecting section 12 by the curved section U, and the screw is used for screwing and fixing the curved section u and the connecting section 12, whereby the above components can constitute the Safety boom (10) and provides support for hanging. However, after the actual use and manufacture, it is found that the safety boom 1 〇〇 still has many disadvantages, for example: I mesh f is combined with the bolt 14 by the branch lock 13 , if the installation is negligent, the bolt is caused If the screw lock of 14 is poor, or the bolt 14 is not secure after long-term use, it is easy to cause the risk of shaking and even falling when the ceiling fan is running. 2. The arc segment " is manufactured separately from the connecting section 12, and the tolerances are limited in manufacturing and drilling, so that the manufacturing cost and difficulty are increased. 3.·There are many components, and the installation is time-consuming and prone to negligence. M350615 4. The curved section U and the material of the connecting section 12 'color and pattern are not consistently consistent', so the appearance is affected. [New Content] Therefore, the object of the present invention is to provide a safety boom that can be manufactured in one piece and that can take advantage of convenience, safety, manufacturing cost, and aesthetics. Thus, the present safety boom comprises an open end, an arcuate section, and a connecting section. The open end is surrounded by an axis in a first radial extent. The arcuate section extends from the open end along the axis and gradually decreases in radial width compared to the first radial extent until a second radial extent is reached. The connecting section is formed around the axis and extends along the axis from the curved section. The arcuate section and the connecting section are integrally formed of a metal material, and jointly define a wearing space extending along the axis. The utility model has the beneficial effects that since the arc segment and the connecting segment are formed by body molding, the manufacturing cost can be greatly reduced, and the appearance is improved, and the screw lock is not required when used, and there is no combination negligence. The dangers that arise are 'capable of taking into account the convenience, safety, manufacturing cost, and aesthetics. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the detailed description of the preferred embodiments. Before the present invention is described in detail, it is to be noted that the parts in the following description of M350615 are denoted by the same reference numerals. As shown in Figures 3 and 4, a first preferred embodiment of the present safety boom 2A includes an open end 21, an arcuate section 20, and a connecting section 30. The open end 21 j λ* 围绕 surrounds an axis χ 疋 with a radial width W1. The arcuate arc segment 20 extends from the open end 21 along the axis , and gradually reduces the radial width compared to the first radial width W1 until the second-to-second width W2, the arc segment 2 ( In the present embodiment, it is hemispherical, and further includes a positioning opening 22 formed on the side, the positioning opening 22 extending from the opening 21 toward the connecting portion 30 along the axis X, the positioning opening 22 Is used to provide - the fixed seat _ on the - bump % for the card engine positioning using the 〆 〆 arc # # 20 in the actual manufacturing thickness is thicker, the positioning opening 22 can also be used without the arc segment 20 0 groove replacement. In the embodiment, the connecting section 3 is surrounded by the second radial width W2 and extends from the curved section 2 along the axis X - body, such as the connecting section 3〇 is jointly defined _ along the axis χ: extended penetration space 40 ′ and is made of an integrally formed metal material, the connecting section 3 〇 can also be made to extend from the brigade section (9) when actually manufactured. The radial width is gradually reduced. When manufacturing the safety boom 200, firstly, a metal pipe is obtained, and the metal pipe is bored in a mold (not shown) having a spherical cavity around the metal pipe and then passing through the high pressure oil. The manner of pouring the metal tube is 'the middle part of the metal tube is formed into the same spherical shape as the spherical cavity, and then the mold is opened to cut the spherical portion in half, and the M350615 segment 3 can be formed and formed. The curved section 20 is constructed to complete the safety rod 200 of the present invention. Thereby, since the arc segment 20 and the connecting segment 3〇 are integrally formed: the manufacturing cost can be greatly reduced, and the components such as the support pin and the screw are not required to be purchased, and the appearance is improved. Then, it is not necessary to combine the screw locks, and there is no danger caused by the inadvertent combination, and the functions of convenience, safety, manufacturing cost, and aesthetics are fully taken into consideration. Lu-5, shown in Figures 5 and 7, the second preferred embodiment of the present invention will be further described below. The second preferred embodiment is substantially the same as the first preferred embodiment described above, except that the arc is The segment 20 further includes a clamping groove 23 formed on one side, and a plurality of ribs 24 projecting from the outer surface of the curved segment at a distance from each other, the positioning groove 23 and the rib 24 are both The opening 钿 21 extends along the axis X toward the connecting section 3 〇. The A connecting portion 30 includes an outer joint portion 3 i which gradually decreases in width relative to the second radial width W2, and an outer positioning portion which protrudes from the outer joint portion 3 toward the φ penetration space 40. 32. The outer positioning portion 32 extends from the end of the connecting portion 30 toward the connecting portion 30 in the present embodiment. The king now protrudes inwardly from the extending space 40 and has a tapered body. The safety boom 200 further includes an extension portion 100 extending along the axis, and the extension portion 50 is assembled from the penetration space 4〇 into the connection portion 3〇 and extends beyond the connection portion 30. The extension portion 5 has an inner joint portion 51 which is tapered in a radial width in cooperation with the outer joint portion 31, an inner positioning portion 52 which is recessed toward the inner portion of the outer positioning portion 32, and an inner joint portion 52 from the inner joint portion The fixing portion 53 extends beyond the connecting portion 30. The inner positioning portion 52 can cooperate with the positioning portion 32 of the outer positioning portion 32, and the inner portion of the groove can be made inside and outside the groove. The fixed section 3 turns, and the inner and outer knots are not relative to the joint:: 延长 the extended section 5. The connecting bundle structure is not integrally worn. In this embodiment, an external thread is formed, and in actual manufacture, it can also be a plug hole for a pin to be inserted. The shape of the positioning groove 23, the ribs 24, the outer joint portion 32, the inner joint portion 51 and the inner positioning mu-die are combined with the high-pressure oil to form the crucible. The formula can also be formed by stamping, and the outer joint portion 31 and the inner knot gob, the 钿 7 β A , 1 J 1 gradually 钿 can also cover the entire connecting portion 30 With this extension 5 〇. Thereby, (4) the effect of increasing the length of 2 30 by the extension 5G, in the embodiment, the extension 50 has a length of - ^ and in actual application, the manufacturer can manufacture various lengths = ...0, in order to match the actual installation environment to achieve the use of different lengths. However, the above-mentioned ones are only a few preferred embodiments of the present invention, 'but the scope of the present invention cannot be limited thereto, that is, simple equivalent changes made according to the scope of the new patent application and the contents of the new manual. And modifications should remain within the scope of this new patent.
