Abstract:
Disclosed is a fastening connection structure, comprising an appendage body (101), a parent body (102) and a fastening connection assembly comprising two or more screw rods (103, 104) and rotation stopping sleeves (117, 119). In the fastening connection assembly, the rotation stopping sleeves (117, 119) are provided with rotation stopping through holes (4), a hole wall of the rotation stopping through hole (4) being provided with a first rotation stopping portion (118); outer peripheries of the rotation stopping sleeves (117, 119) are provided with rotation-stopping insertion strips (121) and/or rotation-stopping insertion slots (120); the parent body (102) and the appendage body (101) are fastened and connected to each other via the screw rods (103, 104); the rotation stopping sleeve (117) is installed outside a rotation-stopping resisting portion (108) of the screw rod (103) and is axially limited, and a second rotation stopping portion (110) cooperates with the first rotation stopping portion (118) so as to restrain the screw rod (103) from rotating relative to the rotation stopping sleeve (117); and the rotation-stopping insertion strip (121) of the rotation stopping sleeve (117) is inserted into the rotation-stopping insertion slot (120) of the rotation stopping sleeve (119) adjacent thereto so as to restrain the adjacent rotation stopping sleeves (117, 119) from relative rotation, and the two adjacent screw rods (103, 104) and the two adjacent rotation stopping sleeves (117, 119) jointly restrain the rotation stopping sleeves (117, 119) from rotating relative to the appendage body (101). The screw rods (103, 104) are both non-rotatably installed together with the parent body (102) and the appendage body (101). The present invention has the advantages of not requiring a rotation stopping piece and any rotation stopping structure, for restraining the rotation stopping sleeves (117, 119) from rotating, on the appendage body (101). The present invention requires no disassembling tool. The rotation stopping sleeves (117, 119) are quick and convenient to disassemble.
