1. A carrying rack connecting device, including:
a connection rod, including a first through hole extending along a first direction and a second through hole extending along a second direction, configured to be connected to a mounting rod in a third direction, the first direction, the second direction and the third direction being perpendicular to one another; and
a connection assembly, including a base, an urging member and an operation member, the base being positioned inside the connection rod, the base including an operation space, the operation space being in communication with the first through hole and the second through hole, the urging member being received within the operation space and movable along the first direction to be protrusive beyond the first through hole for urging an inner wall of the mounting rod, the urging member including a first abutting portion, the operation member being configured to be disposed through the mounting rod, extending within the operation space via the second through hole and being connected to the base, the operation member being movable in the second direction by rotating the operation member, the operation member including a threaded portion and an enlarged portion connected with each other, the threaded portion having a diametric dimension smaller than a diametric dimension of the enlarged portion, the threaded portion being screwed to the base, the enlarged portion including a second abutting portion, at least one of the second abutting portion and the first abutting portion extending in a direction tilted to the first direction and the second direction;
wherein when the second abutting portion pushes the first abutting portion in the second direction, the first abutting portion slides relatively on the second abutting portion so that the enlarged portion pushes the urging member to protrude out from the first through hole in the first direction.
