An adjustment cavity 19 is provided at the bottom end of the distribution box 1 near the adjustment plate 9, and the side wall of the adjustment plate 9 is slidably connected to the inner wall of the adjustment cavity 19, and a maintenance door 20 is hinged at one end of the adjustment cavity 19, so as to facilitate the inspection of the working condition of the adjustment plate 9.

[0027] The threaded hole 10 is connected with a rotating column 11 inside, and a driven bevel gear 14 is sleeved on the outer wall of the bottom end of the rotating column 11. The surface of the driven bevel gear 14 is meshed and connected with the driving bevel gear 15. A connecting rod 21 is installed on the rotating shaft at one end of the driving bevel gear 15. A clamping groove 16 is provided at one end of the connecting rod 21, and a clamping block 17 is connected inside the clamping groove 16. The rotating column 11 is rotatably installed inside the adjustment cavity 19. The top outer wall of the rotating column 11 is provided with an external thread 12. The outer wall of the rotating column 11 and the inner wall of the threaded hole 10 are threadedly connected through the external thread 12, so that the adjusting plate 9 can be driven to move up and down in the adjustment cavity 19 through the rotation of the rotating column 11. The driven bevel gear 14 is fixedly sleeved on the outer wall of the rotating column 11, and a limiting ring 13 is fixedly connected on the outer wall of the rotating column 11 close to the driven bevel gear 14, and the limiting ring 13 is located at the bottom of the external thread 12, so as to limit the adjusting plate 9 to prevent the adjusting plate 9 from colliding with the driving bevel gear 15 and the driven bevel gear 14.
