Referring to fig. 1 to 5, in a first aspect, the present invention provides a connector, including:
the base 100 is a non-revolving body structure, such as an elliptical column, a cube, etc.;

and the separation mechanism is arranged between the rotation transmission mechanism and the axial movement mechanism and used for keeping the rotation transmission mechanism and the axial movement mechanism to synchronously rotate and separating the rotation transmission mechanism and the axial movement mechanism after rotating for a set angle.
By adopting the connecting piece arranged by the structure,
because the base 100 is a non-revolving body structure, the base cannot rotate when being assembled in the LED display screens for splicing, and can be used for locking the deflection angle between two adjacent LED display screens. In the industry, two adjacent LED display screens are usually locked through the transmission shaft 200, and the locking of the deflection angle cannot be realized, so that the locking effect of the invention is better. Meanwhile, the contact area of the non-revolving body structure is larger, and the connection stability can be improved.
When normally rotating axial displacement mechanism, can drive through separating mechanism and rotate drive mechanism synchronous rotation, transmission shaft 200 rotates along with it in step this moment, consequently, locking portion 201 can rotate and realize rotatory joint function, after rotating the set angle, separating mechanism makes axial displacement mechanism and rotation drive mechanism separation, because transmission shaft 200 and rotation drive mechanism no longer rotate this moment, consequently, when continuing to rotate axial displacement mechanism, can drive transmission shaft 200 along axial displacement, and then control locking portion 201 along the axial displacement of transmission shaft 200, can effectively eliminate the gap between two adjacent LED display screens through the axial displacement of locking portion 201 when being used for the LED display screen concatenation, realize complete fixation.
Obviously, by adopting the above operation steps, only the axial moving mechanism needs to be controlled to complete the two steps of rotation and movement of the locking part 201, the operation is simple and convenient, the assembly and disassembly efficiency is improved, and the practicability is high.
