[0012] The working principle and beneficial effects of the present application are as follows:

[0013] 1. The terminal block designed in a cubic shape can better adapt to the shape and size of the terminal box, and through the action of the jack screw, cables of more diameters can be adapted and locked, so that when the specifications of the cables to be connected change, the terminal block and the terminal box do not need to be replaced, and the universality is strong.
