[0024] In this embodiment, a display mechanism 2 is fixedly installed on one side of the inverter 1. The display mechanism 2 is a display screen, which displays the working status of the inverter 1. A slot 3 is provided at the bottom of the display mechanism 2, and a button 4 is installed inside the slot 3. A cavity 14 is provided inside the movable seat 7, and a wiring hole 19 is provided between the cavity 14 and the movable seat 7. A cable 23 is movably installed inside the wiring hole 19, and a copper core 24 is installed inside the cable 23. A limiting slot 15 is provided on the inner wall of the cavity 14, and a supporting mechanism 17 is fixed inside the limiting slot 15. A limiting block 16 is fixed at one end of the supporting mechanism 17, and one end of the limiting block 16 is fixed on the movable plate 8. The supporting mechanism 17 is a supporting spring, and the supporting spring pushes the limiting block 16 to move toward the side of the movable plate 8, thereby driving one end of the movable plate 8 to open outward through the limiting block 16.

[0025] In this embodiment, a receiving groove 18 is provided on the movable plate 8, a groove 25 is provided at the bottom of the cavity 14, a reset mechanism 26 is fixed inside the groove 25, and the reset mechanism 26 is a spring structure. The spring pushes the electrode plate 27 to contact the copper core 24 at all times to realize the connection of the circuit. An electrode plate 27 is fixed at one end of the reset mechanism 26, and one end of the electrode plate 27 is in contact with the copper core 24. A limiting hole 20 is provided on one side of the movable seat 7, and a limiting bolt 21 is movably installed inside the limiting hole 20. One end of the limiting bolt 21 is movably installed inside the fixing hole 9. A connecting hole 22 is provided on one side of the movable seat 7, and a wiring assembly 13 is installed between the connecting hole 22 and the movable seat 7. The limiting bolt 21 is movably installed inside the fixing hole 9 to limit the movable plate 8 as a whole. When the movable plate 8 is received inside the cavity 14, the movable seat 7 can be moved and adjusted inside the support frame 5.

[0026] When the device is in use, first move the movable seat 7 inside the support frame 5, move the movable seat 7 to the rear side of the inverter 1, expose one end of the connecting hole 22 outward, install one end of the external wire inside the connecting hole 22, and squeeze and fix one end of the wire through the wiring assembly 13. After the wiring is completed, rotate and remove the limit bolt 21, and the limit bolt 21 loses the fixing force on the movable plate 8. Under the push of the support mechanism 17, the limit block 16 drives the movable plate 8 to open outward. After the movable plate 8 is opened, it contacts with one side of the support frame 5 for limiting. The fixing bolt is fixed to the inverter 1 through the fixing hole 9 in the use position. When the topological structure needs to be used to expand the number of lines, the copper core 24 at one end of the cable 23 is bent before the movable plate 8 is moved and placed in the wiring hole 19. After the movable plate 8 is shrunk in the cavity 14, an arc groove is opened at the bottom of the movable plate 8, and the copper core 24 passes through the cavity 14. The arc groove is installed on the top of the electrode plate 27. After the copper core 24 is installed, the limit bolt 21 is removed. The movable plate 8 moves outward under the push of the support mechanism 17. The electrode plate 27 and the arc groove are in a left-right misaligned state. The plane at the bottom of the movable plate 8 pushes the copper core 24 to move downward. The copper core 24 moves downward to squeeze the electrode plate 27. Under the squeezing, the reset mechanism 26 of the electrode plate 27 always provides a supporting force. The supporting force ensures that the electrode plate 27 is always in contact with the copper core 24 to complete the circuit connection. One end of the copper core 24 is bent and installed in the storage groove 18. The storage groove 18 and one end of the bent copper core 24 cooperate to achieve limiting. Later, the copper core 24 is taken out from the inside of the storage groove 18 under the pull of external force to avoid external pulling force causing damage to the movable seat 7 as a whole. The movable plate 8 and the connecting hole 22 are displaced front and back to avoid high temperature caused by the wiring position on the same straight line to ensure the normal use of the equipment.
