[0026] Still further, as Figure 1-Figure 4As shown, the reinforcement member 7 includes a first reinforcement plate 701, a second reinforcement plate 702 is arranged at the lower end of the first reinforcement plate 701, a plurality of evenly distributed nuts 703 are arranged on one side of the second reinforcement plate 702, and a plurality of evenly distributed reinforcement bolts 704 are fixedly arranged on the upper end of the first reinforcement plate 701, the reinforcement bolts 704 penetrate the first reinforcement plate 701 and the second reinforcement plate 702 and extend to one side of the second reinforcement plate 702, and the reinforcement bolts 704 penetrate the first reinforcement plate 701 and the second reinforcement plate One end of 702 is threadedly connected to the nut 703.
