The ball connection components 3, 4 are plate-shaped structures, and the arc-shaped groove 7 is provided on the side surface of the ball connection components 3, 4 facing the welded ball 1. In order to make the ball connection components 3, 4 able to fit the outer surface of the welded ball 1 and the overall mass of the ball connection components 3, 4 is light and convenient for operation during use, in this embodiment, preferably, the ball connection components 3, 4 are arc-shaped plate-shaped structures, their outer surfaces are curved surfaces, and an arc-shaped groove 7 is provided on their inner surfaces. The arc-shaped groove 7 is a curved surface structure and is adapted to the outer surface of the welded ball 1, so that when the ball connection components 3, 4 are installed on the welded ball 1, the arc-shaped groove 7 can fit the welded ball 1; when the first connection component and the second connection component are buckled, the two ends of the two ball connection components 3, 4 can contact and be buckled together, and the connection structure is sleeved on the welded ball 1. In this embodiment, preferably, the projection of the ball connection components 3, 4 on the horizontal plane is fan-shaped, that is, when the two ball connection components 3, 4 are buckled, the large-diameter end is circular, and the small-diameter end is also circular, and the corresponding arc-shaped grooves 7 inside construct a curved surface receiving cavity for receiving a part of the welded ball 1, and its inner surface fits a part of the outer surface of the welded ball 1. Preferably, the radius of the arc-shaped groove 7 is adapted to the radius of the welded ball 1 so that the inner surface of the arc-shaped groove 7 can fit the outer surface of the welded ball 1.

A groove 6 is provided on the side surface of the rod connection component 5 facing the rod member 2, and the shape of the groove 6 is adapted to the shape of the outer surface of the rod member 2. In this embodiment, preferably, the cross-sectional shape of the rod connection component 5 is semi-circular. When the two rod connection components 5 are buckled, a cylindrical structure with a through hole in the middle is constructed. When the connection structure is installed, the rod member 2 is located in the cylindrical through hole. Preferably, the radius of the groove 6 is adapted to the radius of the rod member 2 so that the inner surface of the groove 6 can fit the outer surface of the rod member 2.

[0044] The rod connecting member 5 is fixedly installed at the small-diameter ends of the spherical connecting members 3 and 4. The rod connecting member 5 is coaxially arranged with the spherical connecting members 3 and 4. The groove 6 communicates with the arc-shaped groove 7 so that the connecting structure can be installed on the welded ball 1. The welded ball 1 is welded to the rod member 2. The groove 6 is in contact with the rod member 2, and the arc-shaped groove 7 is in contact with the welded ball 1. The connecting structure is sleeved on the welded ball 1.

[0045] In this embodiment, it is set that: the spherical connecting member of the first connecting assembly is the first spherical connecting member 3, and the spherical connecting member of the second connecting assembly is the second spherical connecting member 4. The first spherical connecting member 3 and the second spherical connecting member 4 have the same structure. When installed on the welded ball 1, the first spherical connecting member 3 and the second spherical connecting member 4 are symmetrically arranged; the rod connecting member 5 of the first connecting assembly is the first rod connecting member, and the rod connecting member 5 of the second connecting assembly is the second rod connecting member. When installed on the rod member 2, the first rod connecting member and the second rod connecting member are symmetrically arranged.

[0046] On the other side surface of the spherical connecting member of the first connecting assembly, a guiding groove 12 is provided. One end of a limiting member is rotatably connected to the other side surface of the spherical connecting member of the second connecting assembly. One end of the limiting member is inserted into the guiding groove 12 and slides along the guiding groove 12 to limit the position after the first connecting assembly and the second connecting assembly are buckled, so as to prevent the first connecting assembly and the second connecting assembly from separating. The guiding groove 12 is provided on the outer surface (the side away from the side in contact with the welded ball 1) of the first spherical connecting member 3. The guiding groove 12 is provided at a position near one end of the outer surface of the first spherical connecting member 3. The guiding groove 12 is formed by being recessed inward from the outer surface of the first spherical connecting member 3, and one end of the guiding groove 12 penetrates through the end of the first spherical connecting member 3 and communicates with the outside. For the convenience of the guiding groove 12 and the limiting member to cooperate to limit the buckling of the first spherical connecting member 3 and the second spherical connecting member 4 and prevent the first spherical connecting member 3 and the second spherical connecting member 4 from separating, the shape of the guiding groove 12 is arc-shaped, which can be a quarter circle arc or a semi-circle arc. The shape of the guiding groove 12 is selected and set according to actual needs, and no specific requirements are made here.

[0047] The above-mentioned limiting member is arranged on the outer surface of the second spherical connecting member 4 (the side far from the side in contact with the welding ball 1), and the limiting member is located at one end of the outer surface of the second spherical connecting member 4 corresponding to the end provided with the guiding groove 12 of the first spherical connecting member 3. The limiting member includes a rotating member 13, a connecting rod 14 connected to the rotating member 13, and a movable rod 15 connected to the connecting rod 14. The rotating member 13 is rotatably connected to the second spherical connecting member 4, such as by a rotating shaft. One end of the connecting rod 14 is connected to the rotating member 13, and the other end is connected to the movable rod 15. The axis of the movable rod 15 intersects with the axis of the connecting rod 14, so that the movable rod 15 can be inserted into the guiding groove 12. When the rotating member 13 rotates, it drives the connecting rod 14 to swing, and then drives the movable rod 15 to slide along the guiding groove 12. For the convenience of installing the movable rod 15, a guiding groove is also opened at the corresponding position of the movable rod 15 on the outer surface of the second spherical connecting member 4. The guiding groove penetrates through the end of the second spherical connecting member 4 and communicates with the outside. When the first spherical connecting member 3 and the second spherical connecting member 4 are buckled, the ends provided with the guiding groove 12 are in contact. The guiding groove 12 on the first spherical connecting member 3 is communicated with the guiding groove on the second spherical connecting member 4. The movable rod 15 can slide along the guiding groove 12 on the second spherical connecting member 4 to the guiding groove 12 on the first spherical connecting member 3. At the same time, due to the arrangement of the connecting rod 14 and the rotating member 13, the first spherical connecting member 3 and the second spherical connecting member 4 are buckled together, limiting the buckling of the first spherical connecting member 3 and the second spherical connecting member 4, and preventing the first spherical connecting member 3 and the second spherical connecting member 4 from being separated under force.

[0048] Connecting plates 8 are respectively arranged on the spherical connecting members of the first connecting assembly and the spherical connecting members of the second connecting assembly. The two connecting plates 8 are hinged, so that the first connecting assembly and the second connecting assembly can rotate relative to each other. A connecting plate 8 is arranged at one end of the first spherical connecting member 3 where the guiding groove 12 is not provided, and a connecting plate 8 is arranged at one end of the second spherical connecting member 4 where the limiting member is not provided. This end of the first spherical connecting member 3 corresponds to this end of the second spherical connecting member 4. When the first spherical connecting member 3 and the second spherical connecting member 4 are buckled, the connecting plate 8 on the first spherical connecting member 3 and the connecting plate 8 on the second spherical connecting member 4 are buckled together correspondingly, preferably they can be in contact. The connecting plate 8 is a triangular plate, one end is connected to the rod connecting member 5, the other end is connected to the spherical connecting members 3 and 4, and a first groove 9 is provided at the third end. The first groove 9 on the connecting plate 8 of the first spherical connecting member 3 corresponds to the first groove 9 on the connecting plate 8 of the second spherical connecting member 4.

[0049] On one side of the ball connecting member of the first connecting assembly and the ball connecting member of the second connecting assembly facing the welding ball 1, a chute 16 is provided. The chute 16 is arranged along the circumferential direction of the ball connecting members 3, 4. The chute 16 is arranged on the inner surface of the ball connecting members 3, 4 at the end not connected to the rod connecting member 5.

The limiting blocks 21 can slide along the limiting groove 17, so that both the first limiting member 18 and the second limiting member 19 can move relative to the ball connecting members of the first connecting assembly and the second connecting assembly. The arrangement of the limiting groove 17 and the limiting blocks 21 enables the first limiting member 18 and the second limiting member 19 to be connected to the first ball connecting member 3 and / or the second ball connecting member 4, connects the connecting structure and the positioning structure together, and can freely slide on the first ball connecting member 3 and the second ball connecting member 4 and move to any position. The cross-sectional shape of the slider 20 is adapted to the cross-sectional shape of the chute 16, and the cross-sectional shape of the limiting block 21 is adapted to the cross-sectional shape of the limiting groove 17. The limiting block 21 is arranged on one side surface of the slider 20. The cross-sectional shapes of the slider 20 and the limiting block 21 are approximately L-shaped, so that the slider 20 and the limiting block 21 can freely slide in the chute 16 and the limiting groove 17 respectively.

[0051] Both the first limiting member 18 and the second limiting member 19 are plate-like structures. In this embodiment, preferably, the cross-sectional shapes of both the first limiting member 18 and the second limiting member 19 are arc-shaped, so that the first limiting member 18 and the second limiting member 19 can be attached to the surface of the welding ball 1 to accurately position the welding position of the rod member 2.

[0052] The first stopper 18 and the second stopper 19 are provided with through grooves 22 at the opposite ends. When the first stopper 18 contacts the second stopper 19, the corresponding through grooves 22 form a receiving channel adapted to the shape of the rod, so that the rod passes through the receiving channel and contacts the welding ball 1 to position the welding position of the rod. The through grooves 22 are formed by the inward depression of the end of the first stopper 18 and the end of the second stopper 19. In this embodiment, preferably, the through grooves 22 are semicircular grooves. When the first stopper 18 contacts the second stopper 19, the two through grooves 22 form a circular receiving channel. When the rod passes through the receiving channel and contacts the welding ball 1, the inner surface of the through grooves 22 fits the outer surface of the rod to position the rod.

If the first positioning member 11 is set at the end position of the ball connector 3, 4, the first positioning member 11 is a quarter-circular. Except for the end positions at both ends, the first positioning members 11 located at other positions of the ball connector 3, 4 are all semicircular, and the first positioning member 11 is flush with the large diameter end of the ball connector 3, 4, so that the first positioning member 11 is aligned with the second positioning member 23; there are multiple first positioning members 11, which are set at different positions of the ball connector 3, 4, and the positioning rod 2 is welded at different welding positions of the welding ball 1. The second positioning member 23 is arranged at the corresponding ends of the outer side surfaces of the first limiting member 18 and the second limiting member 19. In the present embodiment, the second positioning member 23 is a quarter semicircle. When the first limiting member 18 contacts the second limiting member 19, the two second positioning members 23 are assembled into a semicircle. When the first positioning member 11 is aligned with the second positioning member 23, the first positioning member 11 and the second positioning member 23 are assembled into a circle so that the first positioning member 11 is aligned with the second positioning member 23.
