DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a universal joint, and more particularly to a universal joint which can be placed at a high angle and has a high torque. [Related Art] FIG. 1 shows a related universal sleeve 1 including a socket 2 and a swinging member 3 pivotally mounted to the socket 2, the swinging member 3 being provided with a ball having a joint portion 4 having a through hole 6. The portion 5 is connected to the neck portion 7 between the joint portion 4 and the ball portion 5 and the pin 8 which is bored through the core 2 and the through hole 6. The distance between the lowest point G1 of the neck 7 depression (ie, the thinnest portion of the neck flesh) and the center of the perforation (ie, the center of the ball portion) is L1, which is smaller than the radius 球 of the ball portion, the neck portion The distance between the lowest point G1 and the center of the ball is short, which causes the drag of the rotating member to be restricted, and the pivoting of the large limb cannot be performed, and the shaft is inconvenient. ❹ Figure 2 shows another related universal sleeve 10 which is designed to be able to pivot at a large angle. The neck 17 is made into a concave shape and the side of the socket 10 is placed. Wall 11 is set lower. The neck 17 concave = the lowest point G2 has a shortest distance between the center of the perforation 16 and the distance U is smaller than the radius η of the ball portion ls, and the swing of the universal sleeve 1〇 = 13 can be performed relative to the socket The pivoting of the large angle, the structural strength of the thin neck 17 is obviously insufficient, and the neck 17 which is long or high-torque is easily deformed, cracked, or even broken, and is not safe and reliable.乂一结构5 200946291 Referring to FIG. 3, since the side wall n of the bearing ίο is low, the neck portion 17 and the ball portion 15 of the oscillating member 13 do not abut against the side wall 11 of the socket n when rotated, so that The torsion of the oscillating member η is transmitted only to the pin 18, so that the pin 18 is extremely compliant, and the life of the universal sleeve is not ideal. τ sin and [invention] Ά 发 发 解决 解决 解决 解决 解决 解决 解决 解决 解决 最低 最低 最低 最低 最低 最低 最低 最低 最低 最低 最低 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' It is more inconvenient. And its slender neck 冓 strength is obviously insufficient, long-term or high-torsion is easy to produce deformation, brakes, Gan rβ Γ this head ρ reliable ▲ 义, even 疋 fracture, this structure is not safe, a capacity The J® soil is provided with two lr_pieces at one end thereof. The swinging member includes a joint portion, a pivoting invention, and a universal joint, which includes a socket, a connection between the portion and the pivot portion. The _ part and the _ part == the connection has a lowest point, the radius of the lowest part. The most button distance, the shortest distance is greater than the pivotal distance between the edge of the paste wall, and the swing y is made at the seat for a large angle, stable and smooth or long f has better structural strength and can withstand The high durability of the big duck has its working performance's better 200946291. [Embodiment] Referring to Figures 4 and 5, a preferred embodiment of the universal joint of the present invention includes a socket 20 and a pivoting The swinging member 3 of the socket 20 is. Referring to Fig. 6, one end of the socket 20 is provided with a receiving portion 21'. The receiving portion 21 is surrounded by a side wall 22, and the side wall 22 is provided with two opposite lateral through holes 23. The other end of the socket 20 is provided with a card portion 24 which, in the preferred embodiment, can be joined by a driving tool such as a wrench or a post. One end of the oscillating member 30 is provided with a pivoting portion 31. The other end of the oscillating member 3 is provided with a joint portion 32. A connecting portion 33 is disposed between the pivot portion 31 and the joint portion 32. The pivoting portion 31 is rotatably received in the receiving portion 21 of the socket 2'. The center of the portion 31 is provided with a pivot hole 34 extending through the pivoting portion 31. The pin-pin 4 is bored through the through hole 23 of the socket 2 and the pivot hole 34' of the swinging member 3'-turning portion 31 so that the swinging member 30 can be pivotally coupled to the socket 2''. In the preferred embodiment, the pivoting portion 31 is substantially spherical, and the pivoting hole is substantially X-shaped in the outer width and the inner portion. The coupling portion 32 can be combined by a driving tool such as a sleeve. 6. Further showing that the connecting portion 33 has a lowest point 3 of the recess (ie, the thinnest portion of the connecting portion), the lowest point (7) of the connecting portion % and the center of the pivot hole 34 (ie, the center of the pivot portion) The shortest distance is l3, and the height of the side wall between the end edge of the side wall 22 and the center of the pivot hole 34 is L4, the sea distance L3 is larger than the radius r3 of the pivoting portion 31 (L3> r3), which is preferably known. In the mode, the L3/r3>l.b L3/L4>1.3. The lowest 200946291 point G3 of the connecting portion 33 is longer than the center of the pivoting portion 31 and the end edge of the side wall 22, and the swinging member 30 can be pivoted with a large angle, stable and smooth with respect to the socket 20. It has improved its working performance and made it easier to operate. Referring to FIG. 7 'the longest distance between the maximum end of the pivot hole 34 of the pivoting portion 31 of the swinging member 30 and the center of the pivot hole 34 is L5, which is not greater than the lowest point G3 of the connecting portion 33 and the center of the pivot hole 34. The shortest distance between L3 (L5SL3). Thus, the swinging member 30 has a better structural strength when pivoting at a large angle, and can withstand high torque or long-term rotation without being susceptible to deformation or cracking. This structure is quite safe and reliable, and its durability and life cycle are better. 8 and 9 show a second embodiment of the present invention, and the difference between the second embodiment and the first embodiment is that the second embodiment adds a bomb body 60. The elastic body 6 is disposed in the receiving portion 2丨 of the socket 2〇 and is elastically pushed against the pivoting portion 31 of the swinging member 30, thereby reducing the shaking of the swinging member 30 and providing a more stable pivot. put. 10 and 11 show a third embodiment of the present invention. The difference between the third embodiment and the second embodiment is that the third embodiment adds two, and the pivoting portion 31 of the movable member 30 is The abutment 6〇 between the elastic bodies 5〇. The sin 60 has an arcuate sinus surface 61' corresponding to the pivoting portion of the oscillating member 3〇, so that the abutting member 6 is pushed against the agitating portion of the oscillating member 30 by the elastic member 5〇. At 31 o'clock, the piece is pivoted. As stated on π, the present invention complies with the requirements of the invention patent, and stipulates according to law. However, the above description is only for the preferred modification of the preferred embodiment of the present invention.
