[0039] Refer to Figure 1 , Figures 4-6, there are also multiple fixing rods 2 provided on the frame body 1, and the multiple fixing rods 2 are detachably connected in a plurality of mounting grooves 12. Second threaded holes 13 are formed on the side walls of the plurality of mounting grooves 12, and third threaded holes 29 are formed at one end of each of the multiple fixing rods 2, and the third threaded holes 29 penetrate through the corresponding fixing rods 2. The frame body 1 is also provided with a plurality of second limiting parts 5 for restricting the fixing rods 2 in the mounting grooves 12, and the second limiting parts 5 are second bolts 51.
