A tool attachment device for assisting a power tool in performing nailing includes a shell assembly, a rocker, a connection device, a driving wheel, and a transmission assembly. A side of the shell assembly is formed with a hole passage. The rocker is partially placed in the hole passage and is rotatable in the hole passage. The connection device is connected to the rocker and rotates synchronously with the rocker. Nail feeding structures are formed on the driving wheel along a circumferential direction of the driving wheel. The transmission assembly is connected to the driving wheel and the connection device and is configured to drive the driving wheel to rotate unidirectionally. The transmission assembly is disposed between the connection device and the driving wheel.

A concrete cutting machine, for wet and dry dual-use cutting, includes a saw blade, which is configured to cut concrete, a motor, which is configured to drive the saw blade to rotate about a first axis, and a bottom plate, which is configured to support the motor and the saw blade. The bottom plate is formed with a first cutting space for the saw blade to pass through. The concrete cutting machine further includes a sliding plate assembly, which is at least partially disposed in the first cutting space, to form a second cutting space smaller than the first cutting space.
