A bottom slider 3608 is fixed to the bottom of the inner slider 3604, and a bottom slide channel connected to the inner slide groove 3603 is provided on the bottom surface of the support rod 32. The bottom end of the bottom slider 3608 passes through the bottom slide channel to the bottom of the support rod 32 and is fixed with a bottom shift block 3609. In the later stage, it is only necessary to pull the bottom shift block 3609 sideways so that the inner slider 3604 moves out of the limit hole 3606 with the limit block 3605, so as to release the limit on the support rod 32 and realize the quick disassembly and assembly operation of the support rod 32 and the support block 31.
