A working machine is provided. The working machine includes a working machine body, a hanging plate adapted to be attached to the working machine body and used to hang the working machine body by hooking a hook, and a marker. The hanging plate includes a plurality of holes that penetrates the hanging plate in a thickness direction thereof and allows the insertion of an end portion of the hook. The marker has a function of indicating a position of a specific hole among the plurality of holes.

A connecting tube used in the power tool is arranged with at least a first material layer made of carbon fiber material and a second material layer made of non-carbon fiber material in a radial direction thereof. The stiffness of the second material layer is smaller than the stiffness of the first material layer, and the toughness of the second material layer is greater than the toughness of the first material layer. On one hand, the above-mentioned connecting tube has a small weight, making the power tool lighter, so that an operator can work more easily; on the other hand, since the connecting tube has good stiffness and toughness, the connecting tube has good impact resistance performance and buffering performance.
