Claim 9:
10. The carrying rack connecting device of claim 6, wherein the enlarged portion is screwed to and disposed around the threaded portion, and the threaded portion is protrusive out beyond the enlarged portion and screwed to the base; the second abutting portion has rigidity smaller than rigidity of the first abutting portion; the first abutting portion and the second abutting portion extend inclinedly relative to the first direction and the second direction, the urging member includes a channel disposed therethrough, the operation member is disposed through the channel and connected to the base, the first abutting portion extends arcuately at a periphery of the channel, and the second abutting portion extends arcuately at the distal end of the enlarged portion; the base further includes a first inner side wall perpendicular to the second direction and two second inner side walls perpendicular to the second direction, the two second inner side walls are separately arranged and laterally connected with the first inner side wall to define the operation space, and the urging member is kept slidably abutted against the first inner side wall and the two second inner side walls; the base further includes a third inner side wall and a perforation, the third inner side wall corresponds to the first inner side wall and is connected with the two second inner side walls, the third inner side wall inclinedly extends relative to the second direction, the first inner side wall, the two second inner side walls and the third inner side wall define the operation space, the perforation is disposed through the third inner side wall in the second direction, and the perforation is in communication with the operation space and the second through hole; the urging member further includes an inclined wall; in the first direction, the first inner side wall and the two second inner side walls is of the same height, the third inner side wall is lower than the first inner side wall so as to form an opening, and when the inclined wall is abutted against the third inner side wall, the urging member is partially exposed from the opening; the threaded portion has a length larger than a length of the enlarged portion; the enlarged portion is cylindrical; the channel is an open structure; the enlarged portion is detachably connected with the threaded portion; the operation member further includes an extension portion, the extension portion is connected with the threaded portion and configured to be connected with and protrusive out the mounting rod, the extension portion is configured to be connected with a fastener; the extension portion has a diametric dimension smaller than a diametric dimension of the threaded portion, a distal end of the extension portion is arcuate, the first abutting portion faces toward the second through hole, the base further includes a threaded hole within which the threaded portion is screwed, when the operation member is not within the operation space, the urging member is abutted against a bottom wall of the operation space in the first direction and is not protrusive beyond the base so that the first abutting portion and the threaded hole overlap in the second direction; during insertion of the operation member, the distal end of the extension portion pushes the first abutting portion to move the urging member, the urging member is disengaged from the bottom wall and slidably abutted against the extension portion, the operation member moves in a direction through the base, the threaded portion pushes the first abutting portion to further move the urging member, the urging member is slidably abutted against the threaded portion, the operation member keeps moving in the direction through the base, and the second abutting portion pushes the first abutting portion to further move the urging member.
