[0002] Fasteners are a type of mechanical part used for fastening connections and are widely used in various industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, hydraulics, etc. Quality inspection fixtures are required when producing such fixtures.
[0003] The quality inspection fixtures currently available on the market have the following problems when used:
[0004] 1. When fasteners are being inspected during production, traditional inspection fixtures typically use a clamping structure to hold the fasteners directly. There is no connection between the fasteners and the inspection fixture. When the clamping structure becomes loose, the fasteners will fall off directly, making the fastener clamping unstable.
[0005] 2. Traditional quality inspection fixtures require a clamping structure to hold them in place. If the clamping structure becomes loose during quality inspection, it can easily affect the inspection results and cause fasteners to fall off, making them inconvenient to use. Utility Model Content
