Abstract: A bicycle kettle support with a tool-storing box including a kettle support haing a lower threaded portion, and a tool box composed of multiple layers of box members and screwed on the lower threaded portion of the kettle support, wherein each of the box members is divided into several chambers by partitioning boards for containing various tools and a cap is rotatably mounted over the box member by a shaft, the cap being formed with an opening corresponding to the shape of the chamber, whereby the cap can be rotated through a certain angle to make the opening aligned with the chamber for the user to take out the tools contained therein while closing other chambers to prevent the tools stored therein from dropping out, the lateral wall of at least one of the box members being formed with a tool insert hole so that the tool can be inserted thereinto, permitting the box member to serve as a handle to increase the wrenching torque exerted on the tool.
