Description

Technical Field

[0001] This utility model relates to a square-hole faucet wrench sanding clamp. Background Technology

[0002] A faucet wrench (also known as a tap wrench) is a wrench used in sinks, kitchens, and other places to control the flow of water, including hot and cold water. Square-hole faucet wrenches, such as... Figure 7 As shown, it includes a wrench handle 60 and a wrench docking part 61. The wrench docking part 61 has a wrench docking cavity 62, and the wrench docking cavity 62 has a square mounting seat 63 and a mounting seat reinforcing rib 64. The wrench mounting seat 64 has a square hole 65. The square hole 65 is designed to accurately align with the faucet mounting seat, which is efficient and labor-saving. During the manufacturing process, the surface of the faucet wrench needs to be sandblasted to improve surface roughness, enhance anti-slip effect, and improve the adhesion of coatings or plating. However, existing faucet wrench sandblasting fixtures still have the following shortcomings in sandblasting operations for specific square hole faucet wrenches: 1. Existing fixture designs are difficult to match the square hole structure of faucet wrenches, which easily leads to displacement or offset during sandblasting, affecting processing accuracy and surface quality; 2. Traditional fixtures are difficult to effectively clamp the square mounting seat, and the clamping force is insufficient or uneven, which may cause the wrench to loosen during processing, increasing the possibility of processing defects. Improvements and optimizations are made to address these issues. Utility Model Content
