Powder quantitative sampling spoon

The quantitative powder sampling spoon comprises a spoon head, a spoon handle, a scraping plate and a push rod, a limiting ring is arranged at the end, close to the spoon head, of the spoon handle, a push rod is movably arranged in the limiting ring in a sleeved mode, and the limiting ring is used for limiting and guiding the push rod and forcing the bottom of the scraper to be tightly attached to the edge of the spoon head all the time. The moving direction of the push rod is the same as the length direction of the spoon handle; a scraper is arranged at one end, close to the spoon head, of the push rod. The push rod is pushed to enable the scraper to move close to the edge of the spoon head, so that redundant samples in the spoon head can be effectively scraped off, the sampling quantity of each time is ensured to be consistent as much as possible, and the sampling efficiency is improved. 本实用新型公开了一种粉末定量取样勺，包括勺头、勺柄、刮板和推杆；所述勺柄靠近勺头的一端设有限位环，所述限位环内活动套设有推杆，所述限位环用于对推杆起到限位和导向的作用，迫使刮板底部始终紧贴勺头边沿；所述推杆的运动方向与勺柄的长度方向相同；所述
