Problems solved by technology

The problem with this connecting device is that it can only be positioned in one direction in the X or Y directions. If simultaneous positioning in the X and Y directions is required, two or more connecting devices must be combined and used together, and the combined device High installation requirements
In this invention, the rigidity of the connection without the driving pin is often very low, and only small parts can be processed. At the same time, the driving pin is very easy to wear due to the wear and tear caused by friction.
[0005] To sum up, the disadvantage of the existing connection device is that it is difficult to realize the use of large and small parts on a set of universal fixtures at the same time, and at the same time ensure high rigidity and durability, especially the accuracy of repeated positioning and repeated positioning of circulation. hard to guarantee
