[0027] In some optional specific embodiments, such as Figures 1 to 5 As shown, a connector 8 is provided at one end of the front face of the junction box housing 1, and a slide rail 9 is fixedly connected to the other end of the front face of the junction box housing 1. A supporting and stabilizing seat 10 is slidably connected to the outer side of the slide rail 9. The supporting and stabilizing seat 10 and a connecting support block 11 are rotatably connected to one end of the bottom of the supporting and stabilizing seat 10. A fastener 2 12 is provided at one end of the connecting support block 11. The supporting and stabilizing seat 10 is slidably connected to the junction box housing 1 through the slide rail 9.
