[0019] The upper and middle ends of the movable slots 8 are respectively provided with limit plates 9, and the upper and middle ends of the opposite sides of the inner cavities of the two movable slots 8 are respectively provided with movable through slots 15, and the opposite sides of the limit plates 9 on both sides are both provided with pull plates 7 through the movable through slots 15 by bolts;

The fixing springs 10 are made of spring steel. In this way, when performing communication connection installation tests and needing to use different wiring ports, it is only necessary to pull the limit plate 9 and the upper ends of the first pair of joints 11 or the second pair of joints 12 to separate them, so that the first pair of joints 11 or the second pair of joints 12 lose their restraining force, and the elastic push rod 14 in a compressed state is lifted up to directly take them for use, thereby increasing the scope of application during use and reducing the limitations during use. In addition, the scope of connection work can be increased by lengthening the wire coil 13, thereby further increasing the applicability during use.

[0021] A plurality of round balls are movably mounted around the top of the first pair of joints 11 and the second pair of joints 12. The top of the first pair of joints 11 and the second pair of joints 12 are provided with mounting circular grooves at positions opposite to the round balls, and the top of the round balls are in contact with the bottom of the limiting plate 9, so that the round balls are driven to rotate when the limiting plate 9 moves, and the friction force of the limiting plate 9 when moving is reduced by the rotation of the round balls;
