The socket 2 is provided with a breaking portion 6 for receiving a ball portion 7 of the swinging member 3, ‘9. Alpha has a pivot hole 8. The lock 4f is disposed on the pivot hole 8 and fixed to the bearing member 3 and pivoted to the socket 2. The spring 5 is provided on the ball portion 7 of the socket 2 and mixed with the county member 3. At the same time, referring to the figure end foot ί, the ball portion 7 of the oscillating member 3 is directly contacted, and the spring 5 of the spring 5 is more likely to emit a periodic noise, and the spring 5 and the pivot hole are more worn by each other. Reduce the life of the product. [Description of the Invention] The magazine of the above-mentioned universal joint is intended to directly contact the rotation, and the end of the magazine is often caught in the ball and the ball is stuck, and the method is smooth. The periodic noise holes are also used to reduce the service life of the product due to mutual wear. The utility model provides a universal joint, a body, a oscillating head, an elastic body and an abutting member. The end of the 200948545 of the main body is provided with an accommodating space, and one end of the oscillating head A pivoting portion is disposed at the other end, and the pivoting portion is pivotally disposed in the accommodating space of the body. The slewing portion is provided with a pivot hole to pass a fixing member to the pivoting portion. The pivot hole is fixed to the body to pivot the rocker to the body, and the elastic body is disposed in the accommodating space of the body. The abutting member is disposed between the pivoting portion of the oscillating head and the elastic body. The abutting member is pushed against the pivoting portion of the oscillating weight by the elastic body. The end leg of the elastic body is prevented from contacting the pivoting σ of the oscillating head by the abutting of the abutting member, so that the oscillating head can smoothly swing, and the swaying portion and the elastic body do not wear each other. The problem, the service life and reliability of the product can be greatly improved. [Embodiment] Referring to Figures 3 and 4, a preferred embodiment of a universal joint of the present invention comprises a body 20, a oscillating head 30, an elastomer 50 and an abutment member 6''. One end of the body 20 is provided with an accommodating space 21 surrounded by a side wall 22, and the side wall 22 is provided with two opposite horizontal holes 23 . The other end of the body 20 is provided with a joint portion 24 which, in the first embodiment, can be combined with a driving tool such as a wrench or a post. One end of the oscillating head 30 is provided with a pivoting portion 31, and the other end of the oscillating head 3 is provided with a joint portion 32. The pivoting portion 31 is rotatably received in the accommodating space 21 of the body 2, and a pivot hole 33 extending through the pivoting portion 31 is disposed at the center of the slewing portion 31. A fixing member 40 is disposed through the hole 23 of the side wall 22 of the body 20 and the pivot hole 33 of the pivoting portion 31 of the oscillating head 30, so that the oscillating weight Dengzhou 200948545 is disposed on the body 20. In the first embodiment, the pivoting portion 31 is substantially spherical, and the engaging portion 32 is engageable by a driving tool such as a sleeve. The elastic body 50 is disposed in the accommodating space 21 of the body 20. The abutting member 60 is disposed between the pivoting portion 31 of the oscillating head 30 and the elastic body 5 ,, and the abutting member 60 is disposed facing the surface of the pivoting portion 31 - corresponding to the shape of the pivoting portion 31 The surface 61 is provided with a card portion 62 on the side of the abutting member 6 toward the elastic body 5'. The card portion 62 can be received and restrained by the end 51 of the elastic member 5''. In the first embodiment, the abutting member 60 has a substantially disk shape, and the abutting surface " 61 is substantially curved. Referring to FIGS. 5 and 6, since the abutting member 60 is located between the pivoting portion 31 of the oscillating head 30 and the elastic body 50, the end leg 51 of the elastic body 50 is abutted by the engaging portion 62 of the abutting member 60. The stop position is such that the elastic body 5 〇 does not contact the pivot portion 31 ′ of the oscillating head 30 ′. The end leg 51 of the elastic body 50 is unlikely to fall into the pivot hole 33 of the pivoting portion 31 , and the oscillating head 30 There is no possibility of jamming and it can be smoothly pivoted. Moreover, there is no problem of mutual wear and tear between the pivoting portion 31 and the elastic body 5, and the service life and reliability of the product can be greatly improved. FIG. 6 further shows that the abutting surface 61 of the abutting member 60 corresponds to the shape of the pivoting 31, so that the abutting member 60 is pushed against the pivoting portion 31 of the oscillating head 30 by the elastic force of the elastic body 50. At this time, the oscillating head 3 〇 can still pivot smoothly. 7 and 8 show a second embodiment of the present invention, and the second embodiment is substantially identical to the first embodiment. The difference is that the abutment member 70 of the second embodiment is embodied in a generally circular shape. An abutting surface 71 corresponding to the shape of the pivoting portion 31 is disposed on a side of the abutting member 7 toward the pivoting portion 31. The abutting member 7 is disposed on a side of the elastic body 50 with a latching portion 72. The end 51 of the elastic member 7 200948545 50 is accommodated and limited. FIG. 8 further shows that the end 51 of the elastic body 5 is located in the clamping portion π of the abutting member 70 and does not contact the pivoting portion 31 of the oscillating head 3〇. The oscillating head 30 can be smoothly pivoted and used. Life and reliability can be greatly improved. According to the above description, the invention complies with the supplementary parts of the invention, and New Zealand proposes a patent application. However, the above description is only the preferred embodiment of the present invention. Those skilled in the art will be able to cover the equivalent modifications or variations of the present invention. ‘ [Simple description of the drawing] Figure 1 is a cross-sectional view of the relevant universal joint.
