The provided clamping protrusion 7 can be embedded and clamped in the inner side of the connecting tube 2 to achieve the limitation of the connecting tubes 2 on both sides;

[0027] The locking assembly is symmetrically arranged on the upper and lower sides of the fastening tube body 1, and is used to drive the sliding assembly to work.
