Embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model.

Fig. 1 is the structure chart of the utility model one preferred embodiment, and together with reference to shown in other each figure, can be clear that from figure the utility model mainly comprises: insulating base frame 1, the terminal group 2 of changeing setting in pressing plate 3 and the insulating base frame 1, wherein:

Insulating base frame 1 inside has and is the grafting space 11 that connects shape, and grafting space 11 1 sides are provided with socket 111, and extend the plurality of terminals groove 12 that can be connected backward, and the groove 13 that can articulate for the axial region 31 that changes pressing plate 3 is set the outside respectively relatively with respect to terminal groove 12 2 in insulating base frame 1 with grafting space 11 in socket 111.
