Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention is shown: the connecting device comprises a shaft body mounting plug 1, a main connecting plate 2 arranged at the end part of the shaft body mounting plug 1, a rotating connecting rod 3 arranged at the center of the end part of the main connecting plate 2 and an embedding mounting groove 4 arranged inside one end of the rotating connecting rod 3, wherein the rotating connecting rod 3 is provided with a main limiting rod 5 protruding outwards at the center of the embedding mounting groove 4, the end part of the main limiting rod 5 is provided with a spherical body 7 with an integrated structure, the main limiting rod 5 and the spherical body 7 are connected through a tangent plane, the tangent plane forms a main arc-shaped structure 6, one end of the spherical body 7 is provided with an auxiliary limiting rod 8 with an integrated structure, the auxiliary limiting rod 8 and the spherical body 7 form an auxiliary arc-shaped structure 12 at the connecting part, the middle part of a rod body of the auxiliary limiting rod 8 is sleeved with a limiting ring 10 through the main connecting rod 9, a limiting area 11 is formed between the inner wall of the limiting ring 10 and the side surface of the auxiliary limiting rod 8, and a plurality of plastic line bodies 13 are embedded at the circumferential gap of the embedding mounting groove 4, the open end of the plastic wire body 13 is opposite to the inner part of the limit area 11 passing through the space position.

The arc slope of the main arc-shaped structure 6 is lower than that of the auxiliary arc-shaped structure 12, so that the plastic wire body 13 cannot be bent too much in the non-working state.
