Description of the Related Art Conventionally, various crushing tools for removing slag accumulated in groove portions between plate materials of a slat surface plate in which plate materials are erected at predetermined intervals are known. For example, there are hydraulic crushing tools and air crushing tools. Among them, the hydraulic crushing tool has a large crushing force, but it is difficult to operate by hand. When the slat (plate material) is hit directly, the slat (plate material) is deformed, and it supports the reaction force and its own weight. It is a heavy muscle work.

  Various types of pneumatic crushing tools are commercially available, such as jet chisel (pneumatic high-speed multi-needle chisel), super keren (high-speed air chisel), lye topic hammer, and the like. Such an air-type crushing tool is inferior in crushing force compared to a hydraulic-type crushing tool, but can be operated manually, and is easier to use than a hydraulic-type crushing tool (see, for example, Patent Document 1).

  Also, a stand for standing work in which various air-type crushing tools can be selectively attached to the tip of a straight arm having a handle and a floor running wheel behind the clamp is commercially available. .

  In addition, a detachable handle is provided at the center of the peeling machine body that has a blade for peeling the flooring material at the tip and a moving wheel at the lower rear part so that the flooring peeling work can be performed in a standing position.
