Bracket connection structure and bracket

A bracket connection structure, used for connecting a supporting piece with a fixed piece of a bracket and comprising a first connection piece detachably mounted on the supporting piece, wherein at least one group of connection hole structures are arranged on the first connection piece;

• at least one group of convex structures are arranged on the fixed piece;
• the connection hole structures comprise two symmetrically disposed jacks, and the convex structures comprise two symmetrically disposed convex clasps;
• the jacks comprise insertion portions and clamping portions which are communicated with each other;
• a clearance of the clamping portions is smaller than that of the insertion portions;
• and the convex clasps are inserted into the insertion portions and move to be clamped into the clamping portions,
• wherein the bracket connection structure further comprises a second connection piece detachably mounted on the fixed piece;
• the convex structures are arranged on the second connection piece;
• the second connection piece is flake-like;
• and the second connection piece is fixed onto the supporting piece through screws, and
• wherein the insertion portions and the clamping portions are perpendicularly disposed;
• the convex clasps consist of connection portions and bent portions;
• one end of each of the connection portions is connected with the fixed piece, and the other end of each of the connection portions is connected with the corresponding bent portion;
• the bent portions are matched with the insertion portions;
• the connection portions are matched with the clamping portions;
• the bent portions are inserted into the insertion portions;
• the convex clasps move downwards to allow the connection portions to be clamped into the clamping portions;
• the bent portions are pressed on the first connection piece at one side of the clamping portions;
• and the connection portions are in interference fit with the clamping portions.
