[0032] The second slider 27 cooperates with the bidirectional screw rod 26 to adjust the position of the junction box body 3.

[0033] In this embodiment, a wire structure 9 is provided on one side of the junction box body 3, and the wire structure 9 includes two racks 31, which are fixedly connected to the junction box body 3. A one-way screw rod 2 32 is rotatably provided on the inner side of one of the racks 31, and a fixed rod 1 33 is fixedly installed on the inner side of the other rack 31, and a baffle 2 34 is slidably provided between the outside of the one-way screw rod 2 32 and the fixed rod 1 33, and a rotating roller 1 35 is rotatably connected between the two racks 31, a fixing rack 36 is fixedly provided on the inner side of the junction box body 3, and a rotating roller 2 37 is rotatably provided on the outside of the fixing rack 36.

[0037] In this embodiment, the spring 25 is located at the periphery of the corresponding guide rod 23, and the bolt fastener 30 is composed of a bolt and a nut.

[0038] The spring 25 cooperates with the guide rod 23 to provide elastic support for the triangular block 24 .

[0039] It should be noted that the present invention is a junction box for power supply transfer. Before use, the device can be placed in a required location to achieve working conditions. First, when two adjacent lines need to be connected, with the junction box in the closed state, the bidirectional screw rod 26 is rotated so that the two sliders 27 carry the two junction box bodies 3 to slide toward the two ends to the predetermined position and then stop. At this time, the junction box is in the fully open state; Then, according to the needs of the line connection direction, remove the bolt fastener 30, and then rotate the junction box body 3 clockwise or counterclockwise 90 degrees as needed and then install the bolt fastener 30. In addition, if two adjacent lines are collinearly connected, the junction box body 3 does not need to be rotated. According to the number of lines to be connected, the slider 3 40 is moved to the corresponding position so that the two adjacent rotating rollers 3 42 separate the lines to prevent them from being entangled. Then, one end of the line is installed on the terminal 4 to complete the connection between the one end of the line and the terminal 4. Then, rotate the one-way screw rod 22 to move the baffle 24 downward until it contacts the outside of the wires and stops. Then, rotate the two-way screw rod 26 to move the two junction box bodies 3 toward the hollow box 10 until the junction box bodies 3 contact both ends of the hollow box 10. At this time, the corresponding hollow block 29 is inserted into the small hole 20 of the hollow box 10. Rotating the one-way screw rod 12 causes the slider 13 to move upward. The slider 13 acts on the baffle 18 through the connecting arm 19, causing it to move with the conductive tube 2 17 toward the conductive plate 15 and insert it into the circular hole of the insulating sleeve 6 to fit the conductive plate 5. During the process, the conductive tube 2 17 pushes the two triangular blocks 24 apart. Under the action of the spring 25, the triangular blocks 24 fit the outside of the conductive tube 2 17. At this time, when the circuit is energized, the two adjacent circuits are energized due to the mutual connection between the conductive plate 15, the conductive tube 2 17, the conductive tube 16, and the conductive plate 2. If the circuit needs to be repaired, the position of the two conductive tubes 2 17 is adjusted by the one-way screw rod 12 to disconnect the conductive tube 2 17 from the conductive plate 5 at the corresponding position, thereby de-energizing the two adjacent circuits.
