[0023] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and not to limit the utility model.

[0024] In the utility model, under the condition that no contrary description is made, the orientation words contained in the terms such as "upper", "lower", "inner" and "outer" only represent the orientation of the terms in the normal use state, or the common name understood by the person skilled in the art, and should not be regarded as the limitation of the terms.

[0025] As Figures 1-5 shown, a kind of rapeseed oil detection sampling tool, including: manual piston unit and at least one oil storage bottle, the manual piston unit includes installation cylinder 1 and the piston that can slide in installation cylinder 1;

[0026] The open end of the installation cylinder 1 is provided with a first threaded part 2, each oil storage bottle includes bottle body 4, both ends are provided with bottle cap 3 and are threadedly connected on both end portions, one end of the bottle body 4 can be threadedly assembled on the first threaded part 2, and a one-way oil passage mechanism is assembled on the end portion of the bottle body 4 away from the first threaded part 2.

[0027] When sampling is needed, first, the bottle cap 3 at both ends of the bottle body 4 is unscrewed and removed, the bottle body 4 is assembled on the first threaded part 2, the end portion of the bottle body 4 away from the installation cylinder 1 is inserted into oil, and the piston in the manual piston unit slides upward in the installation cylinder 1, and the negative pressure generated therein can suck oil into the bottle body 4;After sampling is completed, the manual piston unit is lifted upward, the one-way oil passage mechanism can prevent the oil in the bottle body 4 from flowing downward, the bottle body 4 is unscrewed and removed from the installation cylinder 1, a pair of bottle caps 3 are assembled on both ends of the bottle body 4, the bottle body 4 on the other oil storage bottle is assembled on the installation cylinder 1 to continue sampling, which not only can avoid the mutual mixing of different sampled oils to affect the detection result, but also the oil storage bottle can store oil and facilitate carrying.

[0028] When the oil in the oil storage bottle is needed to be taken out, the bottle cap 3 on the end portion away from the one-way oil passage mechanism is unscrewed, the oil can be poured out from the end portion, or a rubber-tipped dropper can be used for sampling.

[0029] The diameter of the bottle body 4 at both ends does not affect the use of the sampling tool.

[0030] The end of the bottle body 4 away from the one-way oil passage mechanism is provided with a second threaded part 5 matched with the first threaded part 2, and one of the bottle caps 3 is provided with a third threaded part 6 matched with the second threaded part 5.
