The two sets of clamping plates 308 are clamped on both sides of the placement plate 208 to be suitable for supporting the placement plate 208.

[0031] In order to prevent the powder from falling out of the measuring funnel 310, Figure 2 As shown, a fastening unit is sleeved on a group of support rods 301, and a shielding mechanism 5 is installed on the fastening unit. The shielding mechanism 5 includes a receiving plate 501 installed on the fastening unit, a leak hole 503 is opened on the receiving plate 501, and a baffle 502 is slidably inserted on the side of the receiving plate 501, and the baffle 502 is suitable for shielding the end of the measuring funnel 310 close to the bottom plate 1;

[0032] In order to solve the problem that after the same powder is tested, there will be powder remaining in the measuring funnel 310, so as to facilitate the next test.

[0039] After the detection of a powder is completed, the sliding bar 401 is slid downward, and then the scraper 405 is moved into the measuring funnel 310, and then the fixing pin 406 is inserted to fix the sliding bar 401, and then the motor 403 is started to drive the scraper 405 to rotate, so as to clean the powder remaining on the inner wall of the measuring funnel 310;

[0040] In summary, by using the supporting rod 301, the clamping block 302, the inserting plate 304, the fixing plate 305, the second screw rod 306, the handle 307, the clamping plate 308, the measuring funnel 310, the buckle hole 311, the sliding rod 401, the connecting rod 402, the motor 403, the vertical rod 404 and the scraping rod 405, the height of the measuring funnel 310 and the receiving container 102 and the distance between the measuring funnel 310 and the receiving container 102 can be adjusted to improve the diversity of powder property testing.
