Problems solved by technology

[0002] At present, due to the simple, convenient and fast process of laboratory sample analysis, transportation and installation, it has become an important part of the analytical instrument system, and thus is widely used in food, hygiene, medicine, chemical and other inspection and testing fields. In the inspection field, needs A large number of samples are accurately transmitted, but in the process of sample transmission, due to the lack of a suitable sample transmission limit mechanism, the sample transmission is often skewed, resulting in the inability to accurately transmit to the next process, making the next process abnormal analysis and detection of samples. At present, during the sample transfer process of the existing sample transfer device, the sample transfer limit mechanism cannot be adjusted quickly and efficiently according to the width of the sample, resulting in the inability to limit the sample well, resulting in Deviations in sample delivery often require the experimenter to make adjustments, which affects the analysis efficiency of the sample and greatly increases the labor intensity of the experimenter, and the legs of the existing sample delivery device bracket are not firmly fixed on the bottom surface, due to the vibration of the sample The amplitude is large, resulting in the displacement of the sample bracket during the sample transfer process, which affects the normal analysis of the sample transfer device and cannot meet the normal measurement needs
[0003] In addition, in the transmission equipment, the transmission of samples also has the risk of falling. The existing transmission equipment is often carried out with manual assistance, which is less automated, time-consuming and laborious, and there is a danger of injury. In order to ensure safety, the sample The transmission requires reasonable mechanical equipment
