Creation instructions (2) Hitting the impact slot 26 for the hammer shaft χ 6 to rotate against the drive shaft 20, used to loosen or lock the bolts and nuts through the sleeve; There are some problems in the design of the striking part. First, because the hammer 1 6 series is a half-moon arc curved piece, most of the force is concentrated on the edges of both sides of the hammer 丄 6 when the rotary striking action is performed. It will make the hammer 16 deform easily in the process of easy rotation, make it easy to crack during the process of cracking or breaking due to vibration, forming a blow-up jamming phenomenon, affecting the smoothness and accuracy of the pneumatic wrench. , Which further causes damage to the pneumatic wrench and shortens its service life. From the above description, it can be further understood that, because the conventional pneumatic wrench striker has never taught a simple and strong hammer hammer, the conventional striker generally has insufficient structural strength and is easy to deform. : 3 '' It is necessary to make further improvements to enhance its structural strength and extend its service life. = In view of this, the creator has been engaged in research and development in related industries for many years, and has no experience. He deeply explores the above issues and needs, and actively seeks it Ο ί. After long-term research and trial work, he finally successfully developed The structure of the striking part of the aerodynamic wrench with less scoring hammer breaks the structural strength, thereby reducing and cracking the stuck phenomenon, effectively improving its service life.
