ABSTRACT:
The limit structure for the hook of the pneumatic tool, and the area that is preset on the pneumatic tool has a cylinder hook assembly part that can be covered by a loop cover of the hook. A ring groove is placed on the circumferential area of the hook assembly part, and radial through holes are located at two radial spaced locations on the loop cover, so the center line of the through hole can pin through the ring groove. The through fixer goes through the radial through hole and through the corresponding ring groove, and the hook reaches the combination of limit state that is rotatable by locking the middle of these two through fixers in the ring groove. With this structure, it helps the limit structure for the hook of the pneumatic tool to achieve practical effects of simpler production and more convenient assembling.
