It is beneficial to improve the accuracy of the sampling data and improve the service life of the device.

[0003] However, the device requires manual assistance by pulling the handle during the sampling process, which consumes a lot of physical energy for the operator and easily makes him feel tired after long-term operation. Since it relies entirely on manual operation, a certain degree of manual error is inevitable, which will affect the stability and accuracy of the sampling. Utility Model Content
