Detailed ways

Hereinafter, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be combined arbitrarily to form new implementations. example.

Referring to Figures 1 to 3, a rotary connector according to a preferred embodiment of the present invention is shown. The rotary connector includes a first housing 1 and a second housing 2 arranged in sequence from top to bottom. A shell 1 is provided with a cavity 12, and the top of the first shell 1 is provided with an opening communicating with the cavity 12, the bottom of the first shell 1 is provided with a through hole 11 communicating with the cavity 12, and the second shell 1 is provided with a through hole 11 communicating with the cavity 12. The top of the body 2 is provided with a connecting rod, the free end of the connecting rod passes through the through hole 11, and the free end of the connecting rod is detachably arranged with a limiter, the limiter is located in the cavity 12, and the limit The outer diameter of the stopper is larger than the diameter of the through hole 11, and a gap is left between the stopper and the bottom wall of the cavity 12, so that the first shell 1 and the second shell 2 can be opposed to each other in the circumferential direction. By rotating, the relative installation position adjustment between the first casing 1 and the second casing 2 is realized, and the use is more flexible and convenient.

When in use, it is only necessary to connect the first external part to the first shell 1 and the second external part to the second shell 2 to make the first part and the second part rotate relative to each other, so as to realize Circumferential position adjustment between the first part and the second part.

As a preferred embodiment, the first casing 1 and the second casing 2 are coaxially arranged, so that the rotation between the first casing 1 and the second casing 2 is more balanced and smooth, and the first casing The outer diameter of 1 and the outer diameter of the second housing 2 are equal.
