AI Technical Summary
Existing sample extraction devices are difficult to operate with one hand and can only extract liquid samples, which cannot meet the needs of multiple sample types.
A quick-gripping device including a gripping mechanism and a protective device was designed. It enables one-handed operation through a sliding squeeze cap and a replaceable nozzle, facilitating the extraction of liquid and powder samples. The threaded nozzle allows for easy replacement and supports the extraction of different sample types.
It enables convenient sample extraction with one hand, supports efficient extraction of liquid and powder samples, and improves operational efficiency and the versatility of the device.
