The inner surface of the first connecting seat 8 is rotatably connected to the adjusting rod 9. The adjusting rod 9 is rotatably connected to the second connecting seat 10 at one end away from the first connecting seat 8. The first connecting seat 8 and the second connecting seat 10 are connected to the adjusting rod 9 through an axis rod so that the adjusting rod 9 can rotate in the connecting seat. The outer surface of the second connecting seat 10 is fixedly connected to a supporting plate 11, and the lower surface of the supporting plate 11 is slidably connected to the limit seat 4. The inner surface of the limiting slide groove 16 is slidably connected to the limiting slider 17, and the upper surface of the limiting slider 17 is fixedly connected to the support plate 11.
