摘要： A single-tube blowing suction device, including a body, an airflow generation apparatus, a collection apparatus, and a blowing-suction tube. The airflow generation apparatus has an air inlet portion and an air outlet portion and is rotatably mounted on the body. The airflow generation apparatus rotates relative to the body to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion of the airflow generation apparatus is in fluid communication with a first end of the blowing-suction tube, and the air outlet portion is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion is in fluid communication with the first end of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction.

摘要： A chain saw includes a housing, a working head, a protective member, and a pumping mechanism. The working head includes a guide plate and a cutting element arranged around the guide plate. The cutting element moves around the guide plate to implement cutting. The protective member is movably mounted on the housing, and at least partially covered on the working head. The pumping mechanism is configured to deliver a lubricating medium to the working head. The pumping mechanism is configured to output the lubricating medium as triggered by movement of the protective member. When the working head is in a working state, the protective member is pushable by a to-be-cut object to move in a direction away from the working head, to trigger the pumping mechanism to output the lubricating medium.
