The sleeve I needs to be slightly 7 in a circular groove 910, and the outer diameter of the circular groove * is slightly smaller than that of the rod 9 280 M280891浐+ Injury 90 This focus is on the body of the pedestal 90 y - the splicer, as shown in the sixth figure, placed at the entrance of the circular groove 91 。. 5 1352648 then 'punches the top surface of the rod 90' to force the lower portion 901 of the rod 9 插入 into the circular groove 910, as shown in the seventh figure. Thus, the work of closely fitting the rod 90 into the sleeve 91 is completed. It can be clearly seen in the eighth figure that each of the corners of the lower portion 9〇1 of the rod 9〇 is an acute angle and is caught in the inner wall of the slot 910 of the sleeve 91 such that the circular groove 91〇 The inner wall is formed with a corresponding recess 912. This is a result of forcing the lower portion of the rod 9 to be inserted into the circular groove 910 of the sleeve 91. Here, it is noted that the sides of the lower portion 901 of the rod 90 are not in contact with the inner wall of the circular groove 910 of the sleeve 91. Therefore, in the case of using the hand tool connecting rod 9 to loosen or tighten a screw, all the torque is concentrated on each corner of the lower portion 9〇1, and on the inner wall of the circular groove 910. Groove 912. The concentrated mud which is subjected to the torsion force causes the respective corners of the lower portion of the 〇1 to concentrate the force==force the corresponding groove 912, causing the grooves 912 to break and expand again, thereby causing the rod body 9 to be broken. The looseness of the cockroach. "Although the publication M28〇891 further mentions the use of a buckle to axially displace the shaft 90, this can only avoid the rod body and cannot overcome the looseness problem described above. The lower section 9〇1 is a hexagonal column. The circular groove 910 of the 91-direction is not easy to align to the concentric position because of the difference in shape. This makes the lower section 901 may not be inserted straight into the circle. The problem of insufficient concentricity after the combination of the rod body 9〇 and the sleeve 91 is formed in the groove 910. The invention provides a new hand tool connecting rod, which comprises a rod body and a rod The sleeve has a connecting section, a polygonal section continuing the connecting section, and a cylindrical section continuing the polygonal section. The sleeve has a polygonal groove and a cylindrical groove continuing from the polygonal groove. The polygonal slot receives the polygonal section of the shaft and has an inner wall that abuts against the periphery of the polygonal section. The cylindrical slot receives the cylindrical section of the shaft and tightly engages the cylindrical section. Can further be in the cylinder of the rod The surface of the segment is provided with an annular groove, and a convex portion is formed on the inner wall of the cylindrical groove for extending into the annular groove. The convex portion can be used to further ensure that the rod does not fall off the sleeve. In the present invention, by the feature that the inner wall of the polygonal groove of the sleeve abuts against each side of the polygonal segment, the problem that the rod of the conventional hand tool connecting rod is easily loosened can be solved. The cylindrical groove and the rod (four) circle (four) (four) are the characteristics of _, which can overcome the problem that the concentricity of the rod and the sleeve of the conventional hand king money post is not 7 1352648 feet.

佳例子。第一圖顯示該手工具連接桿包括一桿體W 及—套筒20，但該桿體10尚未被植入該套筒2〇。第 一、二圖顯示該桿體1〇已被植入該套筒2〇。 如第一圖所示，該桿體10有一連接段1〇1、接續 該連接段101之一多邊形段u、及接續該多邊形段二 之—圓柱形段12。該連接段1(H、該多邊形段u、與 該圓柱形段12三者同心。該連接段1〇1可以圖中所= 地有-部份非為六邊形，其餘部份均為六邊形，也= :全部均六邊形。該多邊形段u的形狀係為相同於該 ;接段1G1的六邊形。該圓柱形段12的表面有三道環 形槽13(也可，签、 多邊#^ 道），且其最Α外徑是小於該 夕透开又11的外徑。 接择參閲第一圖，該套筒2°有-多邊形槽2卜 形槽二夕邊一形槽21之一圓柱形槽22、及接續該圓柱 曰之一套接槽23。該多邊形槽21盥該套接#% 的形狀為相μ / 接槽23 22的深产”…夕形段11的六邊形。該圓柱形槽 又雨等於或大於該圓柱形段12的長度。更重 8 要的是該圓柱形槽22内徑需略小於該圓柱形段12的 最大外徑。 在第二、三圖中顯示該桿體1〇已被植入該套筒 20的情形。該桿體1〇是用衝壓方式植入到該套筒2〇 内的。如第三圖所示，藉由衝壓的力道，可以強迫該 杯體10的圓柱形段12擠入該套筒20的圓柱形槽22 内，這使得該圓柱形段12被該圓柱形槽22緊緊地束 住，整支桿體1〇也因而不會從該套筒2〇上脫離。 如果需要，也可以讓該套筒20的多邊形槽21的 外徑略小於該桿體的多邊形段11的外徑。如此， 藉由衝壓的力道，也可以強迫該桿體1〇的多邊形段 11擠入該套筒20的多邊形槽21，使得該多邊形槽21 係緊束住該多邊形段11。這可以進一步確保該桿體ι〇 不會從該套筒20上脫離。 請再參閱第三圖，在該桿體10的圓柱形段12擠 入該套筒20的圓柱形槽22内的過程中，因為談圓柱 形槽22内徑較小，所以，該圓柱形段12 一定會推迫 到該圓柱形槽22内壁，被推迫到的部份將依材料延= 性而流動到該圓柱形段12上的環形槽丨3内。4 ， 於在該圓柱形槽22内壁上形成一些凸部22〇，'言此 部220係伸入相對應的環形槽13内，因而具有進一步 1352648 限制該圓柱形段12轴向位移之作用。這意味著，本發 明可以在不使用扣環的情況下，更進—步地確保該桿 體10不會從該套筒2〇上脫離。Good example. The first figure shows that the hand tool connecting rod includes a rod W and a sleeve 20, but the rod 10 has not been implanted into the sleeve 2 . The first and second figures show that the rod 1 has been implanted into the sleeve 2〇. As shown in the first figure, the rod body 10 has a connecting section 1〇1, a polygonal section u continuing from the connecting section 101, and a cylindrical section 12 continuing the polygonal section 2. The connecting segment 1 (H, the polygonal segment u, and the cylindrical segment 12 are concentric. The connecting segment 1〇1 can be in the figure = the ground is partially non-hexagonal, and the rest is six The shape of the polygon is also: all hexagonal. The shape of the polygonal segment u is the same as the hexagon of the segment 1G1. The surface of the cylindrical segment 12 has three annular grooves 13 (also, Multilateral #^道), and its outermost outer diameter is smaller than the outer diameter of the eleventh open. 11. Referring to the first figure, the sleeve has a 2°-polygonal groove 2 a cylindrical groove 22 of the groove 21, and a set of groove 23 connecting the cylindrical cymbal. The polygonal groove 21 形状 the shape of the socket #% is the deep production of the phase μ / the groove 23 22 "... The hexagonal groove is rained to be equal to or greater than the length of the cylindrical section 12. It is more important that the inner diameter of the cylindrical groove 22 is slightly smaller than the maximum outer diameter of the cylindrical section 12. 2 and 3 show the case where the rod body 1 has been implanted into the sleeve 20. The rod body 1〇 is implanted into the sleeve 2〇 by punching. As shown in the third figure, By the force of the stamping, Forcing the cylindrical section 12 of the cup 10 into the cylindrical groove 22 of the sleeve 20, which causes the cylindrical section 12 to be tightly held by the cylindrical groove 22, thereby It will not be detached from the sleeve 2. If necessary, the outer diameter of the polygonal groove 21 of the sleeve 20 can be made slightly smaller than the outer diameter of the polygonal section 11 of the rod. Thus, by the force of the stamping, The polygonal section 11 of the rod body 1 can be forced into the polygonal groove 21 of the sleeve 20 such that the polygonal groove 21 is fastened to the polygonal section 11. This further ensures that the rod body does not escape from the sleeve The cylinder 20 is detached. Referring to the third figure, during the process of the cylindrical section 12 of the rod 10 being squeezed into the cylindrical groove 22 of the sleeve 20, since the inner diameter of the cylindrical groove 22 is small, The cylindrical section 12 must be urged to the inner wall of the cylindrical groove 22, and the portion to be pushed will flow into the annular groove 3 on the cylindrical section 12 according to the material extension. 4 , Forming a plurality of convex portions 22〇 on the inner wall of the cylindrical groove 22, which means that the portion 220 extends into the corresponding annular groove 13 and thus has Further 1352648 limits the axial displacement of the cylindrical section 12. This means that the present invention can further ensure that the shaft 10 does not detach from the sleeve 2 without using a buckle. .
在第四圖中可清楚看到該桿體10的多邊形段u 的每-邊是貼靠著該套筒2〇的内壁，因此，當該桿體 1〇與套筒20承受一扭力時，該扭力是分散到該桿體 10的多邊形段U的每—邊與該套筒2G上相對應的内 壁面’而不是集中在該桿體10的多邊形段u的每一 轉角與該套筒20上相對應的内壁面。因此，習知手工 具連接桿的桿體容㈣㈣問題，並不存在於本發明。It can be clearly seen in the fourth figure that each side of the polygonal section u of the rod body 10 abuts against the inner wall of the sleeve 2〇, so that when the rod body 1〇 and the sleeve 20 are subjected to a torsion, The torsion is an inner wall surface that is distributed to each side of the polygonal section U of the shaft 10 corresponding to the sleeve 2G instead of focusing on each corner of the polygonal section u of the shaft 10 and the sleeve 20 Corresponding inner wall surface. Therefore, the problem of the body capacity (4) (4) of the conventional hand-jointed connecting rod is not present in the present invention.
