Abstract

[Use of item]; This designed item is a ratchet wrench used to tighten or loosen screw joints. ;[Design Description];The characteristics of this design are: from the top and bottom views, the ratchet wrench is long in shape, with the head on the left end and the neck and grip extending to the right. The head is roughly concentric and adjacent to a lightbulb-like knob. The front and back of the neck are concave curved surfaces. The holding part is divided into two sections: conical and rectangular. The wide end of the conical section is connected to the neck, and its narrow end is connected to the rectangular section. A drop-shaped recess is formed in the center of the top surface of the conical section. The tip of the recess is in contact with the button. The narrow ends face each other. In the left side view, the head is oblate with stepped convex portions above and below it. From the right side view, four convex curved surfaces are formed around the grip, forming four ridges extending to the tail end of the rectangular segment. In the front and rear side views, above the neck is the suspended tail end of the button, and the thickness of the holding portion gradually decreases from the wide end of the tapered section to the tail end of the rectangular section. In this way, the ratchet wrench is given a streamlined outline. Not only does the overall shape have a visual aesthetic that is different from traditional wrenches, but it also enriches the strong effect of the mechanical design.
