[0058] The traditional integrated insulating support reserves a fixed number of clamping ports (such as 5), which will be wasted when the cable is 3-wire core. However, the design allows the user to choose to use only the upper support or the lower support according to actual needs, realizing flexible configuration and avoiding resource waste.
