The main technical purpose is to install and insert a plastic fitting sleeve into the body of the angle club head, so that the plastic fitting sleeve is firmly combined with the body to obtain the ball of the embedded group. The head has the functions of precise positioning, no looseness, increased rotation angle, and durability. [Previous technology] ·· According to the conventional universal joint structure, as shown in Figures 1 (A),), and 1 (C): a hollow body J is provided with a rubber bushing 2 and a rubber bushing 2 In the inserting group, a rotation angle rod 3 ball head 4 is provided, and a cover 5 and a riveting are arranged in the upper body 丨 to prevent the rotation angle rod 3 ball head 4 from coming out, and it is fitted below-dustproof rubber sleeve 6, 'In fact, there are the following (1) the colloidal bushing 2 has the upper half of the supporting ball 5 | 4, ... 枓 诂 stands ^ θ each head 4, as shown in Figure 1 (B), so the ball head 4 is in a relatively In the high position, the rotation angle is 0. (2) The gel bushing 2 is an independent entity, and then put into the body i to integrate with the body 1, so there must be 2, that is, a non-ball head. The 4-turn angle lever 3 cannot be precisely positioned up and down. The appearance of “A” (3) The rubber bushing 2 will loosen up and down, causing problems with the internal cutting of the body. This friction will cause increased wear and abrasion of the soil a. , T, even easy to break (4) If you want to increase the rotation angle θι, you need to reduce the rotation angle rod 3 will affect the durability and safety.

四、創作說明（2) 請參閱圖二、三，係一中* 形凹槽n，再於本體10内；=，於1内壁設有環 f型膠質嵌合_，膠質嵌合;2角：=^ 且可形成具有阻定凸緣21結合於本體i。之環：丄 【實施方式】： 本創作之製成··初始時如圖二（ 一 度桿3球頭4置入具有環形凹上二)。：不再 模具中予本體1〇内壁與球頭4間射出成型膠質嵌：=( 丨^圖三B)，得膠料填滿本體1〇之環形凹槽u，:得形成 膠質嵌合套20及膠質嵌合套2〇具有阻定凸緣21，並且盥 體10内壁結合一體，再於本體1〇上方鉚合一封蓋5及^方 套合一防塵膠套6，即完成成品（如圖三c )。 本創作之膠質欲合套20係採用「耐磨」之膠料，而本 體10内壁可設成粗糙面、轉角度桿3之球頭4表面設成光滑 面’因此，可形成膠質嵌合套2 0與本體1〇内壁牢固結合一 體、球頭4轉角度桿3可旋轉角度。 藉由上述之結構，得具有下列功效、優點： (1) 設成膠質嵌合套20呈一體射出結合於本體1〇内壁，得 丨定位牢固之效果，且，本體10又設有環形凹槽丨丨、膠 質嵌合套20形成有阻定凸緣21，更使膠質嵌合套2〇得 定位牢固之效果，而得使膠質嵌合套2〇不會有上下鬆 動之虞。 (2) 膠質欲合套20不會上下鬆動，得確保球頭4轉角度桿34. Creation instructions (2) Please refer to Figures II and III. The * -shaped groove n in the first middle is in the body 10; =, a ring f-shaped gel-fitting _ is provided on the inner wall of the -1, gel-fitting; 2 corners : = ^ And can be formed with a blocking flange 21 coupled to the body i. Ring: 丄 [Embodiment]: The creation of this creation is initially shown in Figure 2 (a 1-degree rod 3 ball head 4 is placed with a ring-shaped concave upper 2). : No longer injection molding gel insert between the inner wall of the body 10 and the ball head 4 in the mold: = (丨 ^ Figure 3B), the rubber material fills the annular groove u of the body 10, and a gel fitting sleeve is formed 20 and the gel-fitting sleeve 20 have a blocking flange 21, and the inner wall of the toilet body 10 is integrated, and then a cover 5 and a square sleeve are riveted above the body 10 to form a dust-proof rubber sleeve 6 to complete the finished product ( See Figure 3c). The gelatinous sleeve 20 created by this creation is made of "wear-resistant" rubber, and the inner wall of the body 10 can be set as a rough surface, and the surface of the ball head 4 of the angle rod 3 can be set as a smooth surface. 20 is firmly integrated with the inner wall of the body 10, and the ball head 4 rotates the angle rod 3 to rotate the angle. With the above structure, the following effects and advantages can be obtained: (1) The colloidal fitting sleeve 20 is integrally projected and combined with the inner wall of the body 10 to obtain a firm positioning effect, and the body 10 is provided with an annular groove.丨 丨 The colloidal fitting sleeve 20 is formed with a blocking flange 21, so that the colloidal fitting sleeve 20 can be firmly positioned, so that the colloidal fitting sleeve 20 does not risk loosening up and down. (2) The plastic fit sleeve 20 will not loosen up and down, so that the ball head 4 turns the angle rod 3

(3) The colloidal fitting sleeve 20 will not loosen up and down, so there will be no problem of "rubber fitting sleeve rubbing with the inner wall of the body 10 due to looseness". It has no abrasion with the inner wall, and can have high precision and durability. efficacy. (4) Because there is no problem of loosening, the ball head 4 can be located at a lower position of the gel fitting sleeve 20, so that the ball head 4 rotation angle rod 3 can have a larger rotation angle (9 2 effect. (5 ) In addition, the groove 11 of the body 10 can also be set in a straight strip shape, and the injection molded plastic fitting sleeve 20 resists the flange 21 also in a corresponding straight strip shape. In summary, The structure does have excellent practicability and > enhanced efficacy, which is in line with the gist of the new patent, and I would like to ask for a patent.
