[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the novel universal joint comprises a joint base 1, a fixed shaft 2 is provided on the joint base 1, and a ball head 3 is provided on the upper part of the fixed shaft 2, a universal swing component swinging around the ball head 3 is provided outside the ball head 3, the universal swing component is composed of a swing chassis 4 and a swing upper plate 5, a conical connecting plate 6 is provided on the top of the swing upper plate 5, a sealing component is provided between the swing upper plate 5 and the swing chassis 4, under the action of the ball head 3, the universal swing component can perform universal swing, and the universal swing is not cast, but is formed by combining and connecting the swing chassis 4 and the swing upper plate 5 which are divided into upper and lower parts, so that it is convenient to replace individual parts after the ball head 3 is worn.

[0014] To further explain, the sealing assembly includes a sealing ring 7 and sealing retaining protrusions 8 formed on the top and bottom of the sealing ring 7. Both the swing base plate 4 and the swing upper plate 5 are provided with grooves for positioning and installing the corresponding sealing retaining protrusions 8. The sealing ring 7 is positioned to seal between the two, preventing water from entering between the two and remaining on the ball head 3 to cause rust, thereby reducing the wear of the ball head 3.

[0015] Preferably, a connection disk 9 is provided on the top of the conical connection disk 6, and the connection disk 9 has an external thread.

[0016] Preferably, the fixed shaft 2 is fixed to the joint base 1 through a fixing cap.

[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0018] Although the present invention uses more terms such as joint base 1, fixed shaft 2, ball head 3, swing bottom plate 4, swing upper plate 5, conical connecting plate 6, sealing ring 7, sealing positioning protrusion 8, connecting plate 9, etc., it does not exclude the possibility of using other terms. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
