[Prior Art] Press, technology is changing with each passing day. Many products and components are manufactured and assembled by machine instead of labor, which greatly increases production capacity. Despite this, many pieces of fasteners, as well as industrial products, are locked, combined, and even repaired. Due to the difference in structure and precision, they can be used for applications such as heavy industry such as aviation, shipbuilding and sedan. The screw locks must be assembled with a wrench with a considerable strength to achieve a solid structure, which can withstand the impact of gas and power; and the above-mentioned screw locks assembled with a relatively strong torque are mostly large-volume workpieces. 'In order to loosen the tightening screw, it is necessary to apply a stronger force f to force the force to dismantle the torque* and not to achieve the purpose of loosening the lock. It may happen that the screw is too large in torque, which causes the screw to collapse before unscrewing, which increases the difficulty of the operation; therefore, the wrench tool acts as a control torque, and the cover screw is in the Group bad = When slamming, insufficient torque or excessive torque may cause the screw lock to collapse and the method achieves its intended effect, resulting in the structure of the industrial finished product. 3 M400389 [New content] In view of the above problems, the author believes that it is necessary to design a manual impact wrench structure that is easy to rotate large workpieces while preventing the workpiece from being driven and damaged.
