Material life such as clothing, food, housing, transportation, and spiritual life such as culture, art, and entertainment all need chemical products to serve them. The demand for chemical industry increases year by year, and the demand for chemical tools and equipment also increases accordingly. Take the sampler of liquid chemical products as an example. It is mainly used for sampling and testing liquid chemical raw materials. However, in the process of sampling liquid chemical raw materials, the existing sampler often requires workers to hold the sampler close to the liquid chemical product storage tank and pull the sampler's liquid extraction rod hard to extract and sample the liquid raw materials. Therefore, there are problems such as low degree of automation, waste of manual labor, and the risk of workers falling when they are too close to the storage tank.

[0003] For example, Chinese patent No. CN202021534830.X discloses a low-melting-point chemical product detection sampler, during the design process, the liquid drawing block is inserted into the chemical product solution, and the handle is pulled upward by hand. The upward movement of the handle will drive the pull rod to move upward, and the upward movement of the pull rod will drive the sealing disk at the bottom of the pull rod to move upward close to the inner wall of the sample tube, and the sealing disk will absorb the chemical product solution into the inner wall of the sample tube; however, it has the problem that the worker needs to hold the sampler close to the liquid chemical product holding pool and pull the liquid drawing rod of the sampler hard to extract and sample the liquid raw material. Therefore, there is a low degree of automation, waste of manual labor, and the worker is prone to fall when he is too close to the holding pool, so it needs to be improved. Utility Model Content
