[0031] Please refer to Figure 3 - Figure 6The reinforcing mechanism 2 is located at the bottom of the base 1 and is used to improve the stability when the base 1 is in contact with the ground. The reinforcing mechanism 2 comprises a plurality of supporting blocks 6 fixed at the bottom of the base 1, an expansion assembly located at one side of the supporting blocks 6 and used to improve the contact area of the base 1 with the ground, a positioning assembly located at the top of the expansion assembly and used to position the expansion assembly, and a pressing assembly located at the bottom of the base 1 and used to press the expansion assembly. The expansion assembly comprises a fixed plate 21 fixed at one side of the supporting blocks 6 and a movable plate 22 rotatably installed at the bottom of the fixed plate 21. The inside of the movable plate 22 is provided with a receiving cavity, and the receiving cavity is installed with a telescopic plate 28. The positioning assembly comprises a positioning box 23 fixed at the top of the movable plate 22 and a cavity provided in the inside of the positioning box 23.
