The conventional universal sleeve 10 mainly includes a female seat 11, a joint piece 12, a pin 13, a sliding sleeve 14 and a spring 15. The female seat 11 At one end is provided with a driving end 111 for the sleeve connection of pneumatic or electric tools (not shown), and at the other end is provided with a receiving slot 112 into which the connector 12 is placed. The female seat 11 is located on the inner wall of the receiving slot 112 Two longitudinal grooves 113 are further recessed on both sides of the connector 12, one end of the joint 12 is made with a ball head 121, and the other end is provided with a tool head (not shown) of a predetermined pattern for nesting installation At the end 122, the neck of the ball head 121 is restricted by the convex top of the female seat 11 embedded with two steel balls (not shown), so that the joint piece 12 can be connected with the female seat 11, passing through the center of the ball head 121 A pin hole 123 is provided for the plug pin 13 to penetrate transversely. The two ends of the plug pin 13 protrude from both sides of the ball head 121 and are clamped into the two longitudinal long grooves 113, thereby enabling the joint 12 and the female seat 11 to form a linkage The joint part 12 can be tilted and swiveled in the female seat 11 by using the ball head 121, thereby changing the connection angle of the tool head, so that the pneumatic or electric tool can drive the tool head to rotate at a high speed through the universal sleeve 10, The tool head can use the universal sleeve 10 to conveniently change various angles to disassemble and assemble the bolt.

上述專利案揭示以插銷13穿設於球頭121所構成之接頭件12,普遍應用在目前常見的萬向套筒10結構中,然而此種萬向套筒10結構卻存在有下列問題: The above-mentioned patents disclose that the joint member 12 formed by inserting the pin 13 through the ball head 121 is commonly used in the current common universal sleeve 10 structure. However, this universal sleeve 10 structure has the following problems:

1.利用插銷13穿入銷孔123所構成之接頭件12,由於插銷13與接頭件12是兩個分開獨立的構件,兩者必須分別製造、分別控制其配合精密度,且在組裝上也必須先行將插銷13穿入銷孔123內,該接頭件12接著才能組入母座11內進行組裝,在現今人力成本不斷提高的前提下,此種製造及組裝步驟過多,勢必會造成製造與組裝成本的增加,不利於後續產品之競爭。 1. The connector 12 formed by inserting the pin 13 into the pin hole 123, since the pin 13 and the connector 12 are two separate and independent components, they must be manufactured separately, and the precision of their matching must be controlled separately, and the assembly is also The plug pin 13 must be inserted into the pin hole 123 first, and the connector 12 can then be assembled into the female seat 11 for assembly.

2.利用插銷13穿設於銷孔123內所構成之接頭件12,由於插銷13與接頭件12互為兩個獨立構件,在實際使用上,插銷13與接頭件12銷孔123之間必然存在有相互磨擦而造成破損的問題,一旦插銷13與接頭件12之間有磨擦破損情況時,容易導致該接頭件12在使用過程中產生鬆動滑脫,在萬向套筒10高速旋轉作業下,可能會造成其內部零件有甩出之工安問題發生。 2. The connector 12 is formed by inserting the plug 13 into the pin hole 123. Since the plug 13 and the connector 12 are two independent components, in actual use, there must be a gap between the pin 13 and the pin hole 123 of the connector 12 There is a problem of damage caused by mutual friction. Once there is friction and damage between the plug 13 and the joint 12, it is easy to cause the joint 12 to loosen and slip during use, and the universal sleeve 10 rotates at a high speed. , It may cause industrial safety problems that its internal parts are thrown out.

The reinforcing ribs 313 connect the ball head 311 and the convex portion 312 in an integral shape. The structural strength of the protruding portion 312 is indeed improved, so that the joint member 30 can withstand long-term working conditions and has the effect of increasing the service life.

此外,本發明所提供之製造方法並不僅以上揭實施例為限,如第7圖所示,為本發明提供第二實施例的接頭件70構造,該接頭件70同樣設有一接頭端71,該接頭端71具有一球頭部711及二凸部712,其同樣具有簡化組裝步驟以減少製造時間與成本之功效,以及可徹底解決習知以插銷13穿設於接頭件12銷孔123中之組裝結構,在使用一段時間後,插銷13與銷孔123之間容易因磨擦產生破損的問題,與上揭第一實施例之差異在於:該接頭件70的凸部712是被加工機具切製成多角柱狀,可為三角柱狀、四角柱狀或五角柱狀等多角柱形狀,本實施例係以四角柱狀為例,利用此種多角柱形狀設計,可減少凸部712在一體成形之鍛造加工後的切邊工作,製造上可更為容易。 In addition, the manufacturing method provided by the present invention is not limited to the above-discussed embodiment. As shown in FIG. 7, the structure of the connector 70 according to the second embodiment of the present invention is provided. The connector 70 also has a connector end 71, The joint end 71 has a ball head 711 and two protrusions 712, which also have the effect of simplifying the assembly steps to reduce manufacturing time and cost, and can completely solve the conventional problem by inserting the plug 13 into the pin hole 123 of the joint 12 After using for a period of time, the plug 13 and the pin hole 123 are easily damaged due to friction. The difference from the first embodiment mentioned above is that the convex portion 712 of the joint 70 is cut by a processing tool. It can be made into a polygonal column shape, which can be a triangular column shape, a quadrangular column shape, or a pentagonal column shape. This embodiment takes the quadrangular column shape as an example. The design of this polygonal column shape can reduce the convex part 712 in the integral shape. The trimming work after forging is easier to manufacture.

惟,以上各實施例之揭示僅用以說明本發明,並非用以限制本發明,故舉凡數值之變更或等效元件之置換仍應隸屬本發明之範疇。 However, the disclosures of the above embodiments are only used to illustrate the present invention, and not to limit the present invention. Therefore, all changes in numerical values or replacement of equivalent components should still belong to the scope of the present invention.

綜上所述,當可使熟知本項技藝者明瞭本發明確可達成前述目的,實已符合專利法之規定,故依法提出申請。 In summary, when people who are familiar with this technique can understand that this invention can clearly achieve the aforementioned purpose, it has actually complied with the provisions of the Patent Law, so they file an application in accordance with the law.
