Claim 19:
20. An apparatus comprising:
a base, the base defining a first arc-shaped concave cavity and a second arc-shaped concave cavity, the base further defining an outer side portion, the outer side portion comprising:
a first rack located on a first end of the base;
a second rack located on a second end of the base;
a connecting column positioned between the first rack and the second rack, the connecting column further comprising an end that includes a limit flange and a convex block in a middle of the connecting column; and
a sector block that protrudes from a curved wall of the limit flange; and

an upper cover, the upper cover defining a first pressing concave cavity corresponding to the first arc-shaped concave cavity and a second pressing concave cavity corresponding to the second arc-shaped concave cavity, the upper cover and the base are configured to form a pipe cavity when assembled together, the upper cover further comprising:
a perforation corresponding to the connecting column, the perforation comprising a hook configured to stop the limit flange to prevent the upper cover from coming out and at least one first stopper provided on an inner wall of the perforation, the connecting column configured to penetrate through the perforation so that the upper cover can rotate around the connecting column;
a first insertion slot corresponding to the first rack, the first insertion slot further comprising a first clamping edge configured to act on the first rack; and
a second insertion slot corresponding to the second rack, the second insertion slot further comprising a second clamping edge configured to act on the second rack,

wherein when the first and second clamping edges act on the first and second racks, the upper cover and the base are locked relative to each other,
wherein when the sector block and the at least one first stopper are axially overlapped or partially overlapped, an axial displacement of the connecting column is restricted, and
wherein the axial displacement of the connecting column is restricted, the convex block is pressed against the hook.
