[0022] refer to Figure 1 , Figure 2The fixing assembly 8 includes a fixing pin 10, a spring 11 and a pull rod 12. The fixing pin 10 is slidably connected to the inside of the fixing installation cavity 6. The spring 11 is fixedly installed on the inner wall of the fixing installation cavity 6. The end of the spring 11 away from the inner wall of the fixing installation cavity 6 is fixed to one end of the fixing pin 10. The fixing pin 10 is inserted into the inside of the fixing slot 7. The end of the fixing pin 10 away from the spring 11 is an arc-shaped structure. A pull rod 12 is fixedly installed on one end of the fixing pin 10. The pull rod 12 extends to the outside of the fixing cylinder 2. The spring 11 is sleeved. On the outer surface of the pulling rod 12; when the feed hopper 3 is inserted into the interior of the fixed cylinder 2 and the limiting slide block 5 enters the interior of the limiting slide groove 4, at this time, one end of the limiting slide block 5 and the end of the fixed pin 10 away from the spring 11 are an arc structure, and the fixed pin 10 compresses the spring 11 and enters the interior of the fixed installation cavity 6. Then when the fixed slot 7 contacts the fixed pin 10, the fixed pin 10 enters the interior of the fixed slot 7 under the action of the rebound force of the spring 11 to fix the feed hopper 3, so that the feed hopper 3 is more stable inside the fixed cylinder 2.

[0023] refer to Figure 1 , Figure 2 and Figure 3 A circular end cover 13 is provided on the top surface of the feed hopper 3, a U-shaped pull rod 17 is fixedly installed on the top surface of the circular end cover 13, an arc-shaped positioning groove 14 is opened on the top surface of the feed hopper 3, an arc-shaped positioning block 15 corresponding to the arc-shaped positioning groove 14 is fixedly installed on the bottom surface of the circular end cover 13, the arc-shaped positioning block 15 is inserted into the inside of the arc-shaped positioning groove 14, and a sealing gasket 16 is fixedly installed on the bottom surface of the circular end cover 13; the circular end cover 13 is provided to facilitate sealing the top of the feed hopper 3 to prevent external debris from entering the inside of the feed hopper 3, the arc-shaped positioning block 15 is inserted into the inside of the arc-shaped positioning groove 14, so that the circular end cover 13 is conveniently positioned and installed, and the sealing gasket 16 is provided to facilitate improving the sealing between the circular end cover 13 and the feed hopper 3.

[0024] The implementation principle of an analyzer embodiment of the present application for powder property testing is as follows: the user first inserts the feed hopper 3 into the interior of the fixed cylinder 2 and allows the limit slide block 5 to enter the interior of the limit slide groove 4. When the limit slide block 5 enters the limit slide groove 4 and continues to move downward, one end of the limit slide block 5 contacts one end of the arc-shaped structure of the fixed latch 10. At this time, the fixed latch 10 compresses the spring 11 and enters the interior of the fixed installation cavity 6. When the fixed slot 7 contacts the fixed latch 10, the fixed latch 10 enters the interior of the fixed slot 7 under the action of the rebound force of the spring 11 to limit and fix the feed hopper 3 inside the fixed cylinder 2 to improve its stability. After the feed hopper 3 is fully limited and installed in the interior of the fixed cylinder 2, the bottom end will extend from the interior of the fixed cylinder 2 and contact the two semicircular baffles 9 to push it outward. The hopper 3 is convenient for personnel to introduce the powder into the interior of the feed hopper 3, thereby facilitating the powder to enter the interior of the dispersion cylinder through the feed hopper 3. When the feed hopper 3 needs to be disassembled and transported to the powder test analyzer body 1, it is only necessary to pull the pull rod 12 outward so that the fixed latch 10 releases the restriction on the limit slider 5 and the feed hopper 3 to disassemble the feed hopper 3. After the feed hopper 3 is disassembled, the two semicircular baffles 9 are closed together under the action of the torsion spring to seal the bottom end of the fixed cylinder 2, and the dust of the feed hopper 3 is prevented from entering the interior of the dispersion cylinder through the fixed cylinder 2 when the feed hopper 3 is not installed. The device has a simple structure and is easy to operate. It is more convenient to limit and fix the feed hopper 3 by plugging and installing it, and after the feed hopper 3 is plugged and installed in the interior of the fixed cylinder 2, the two semicircular baffles 9 can be effectively pushed open, so that the powder enters the dispersion cylinder.
