Problems solved by technology

Because they are hard-connected, they have the disadvantages of occupying a large space after shrinking, small working stroke and heavy weight after expansion, and once the stretching force exceeds the strength of the sub-rod, the sampling rod will fail as a whole

Description

1. Technical field [0001] The invention relates to an automatically controlled sampling rod, in particular to a coil spring type retractable sampling rod with small volume and large stroke. 2. Background technology [0002] Against the background of the rapid development of automatic control and robot technology, humans are increasingly relying on robots and other automated equipment to collect materials for analysis in inaccessible and dangerous places, such as relying on automatic samplers to collect materials from the moon, Mars and other space fields, as well as north-south Ores, soil, ice and snow in polar, nuclear or chemically polluted areas. The power of automation equipment such as robots working in the above places is generally provided by solar energy, wind energy, etc., and the power of these green energy sources is limited, which puts forward requirements on the power of the autosampler. At the same time, since the autosampler needs to be transported from the l...
