The convenient component includes a scale 12, the outer wall of the scale 12 is fixedly connected to the outer wall of the storage tube 2, the interior of the storage tube 2 is fixedly connected with a perspective window 13, the interior of the inner baffle 19 is slidably connected with an extension plate 20, the top of the inner baffle 19 is fixedly connected to the inner wall of the storage tube 2, the interior of the partition plate 17 is slidably connected with a cleaning plate 21, the outer wall of the cleaning plate 21 is attached to the inner wall of the storage tube 2, the interior of the cleaning plate 21 is fixedly connected with a telescopic rod 22, and one end of the telescopic rod 22 is fixedly connected to the inner wall of the partition plate 17;

[0027] Specifically, first pull the rotating sleeve 6 to slide along the outer wall of the outer shell 1, which will drive the storage tube 2 to move out from one end of the outer shell 1. As the storage tube 2 moves out, the connecting plate 5 will fit with the bottom of the outer shell 1, so that the lower buckle 8 moves to the inside of the female buckle 4 at the bottom of the outer shell 1, thereby fixing the connecting plate 5 and the storage tube 2. Next, insert the storage tube 2 into the interior of the N-phenylpyrrolidone finished powder and pass it through the through hole on one side of the storage tube 2 so that the finished powder fills the interior of the storage tube 2. Then rotate the rotating sleeve 6 so that it rotates on the outer wall of the connecting plate 5. , the limit block 11 will slide inside the rotating sleeve 6, and then drive the rotating rod 7 and the sub-button 8 to rotate through the sliding shaft 10. When the sub-button 8 rotates 90 degrees, the connecting plate 5 will no longer be constrained. At this time, the storage tube 2 can be pulled back to its original position, and the sub-button 8 on the upper side of the connecting plate 5 can be moved to the inside of the female buckle 4 on the top of the outer shell 1, and the storage tube 2 can be fixed again. At this time, the sealing baffle 3 will block the through hole of the storage tube 2, thereby realizing the storage of the finished powder, so that it can be carried and moved separately. Finally, the interior can be observed through the scale 12 and the perspective window 13.

[0028] Reference Figure 1 、 Figure 5 and Figure 6 The storage tube 2 is rotatably connected to a telescopic rod 14, one end of the telescopic rod 14 is fixedly connected to a rotating seat 15, and the other end of the telescopic rod 14 is fixedly connected to a screw 16. The outer wall of the outer shell 1 is fixedly connected to a handle 24, and the outer wall of the screw 16 is threadedly connected to a partition plate 17.

[0029] Specifically, the driving rotating seat 15 drives the telescopic rod 14 and the screw 16 to rotate, so that the partition plate 17 slides on the outer wall of the screw 16, and then the partition plate 17 slides on the inner wall of the storage tube 2. When the partition plate 17 moves, it will drive the outer baffle 18 and the cleaning plate 21 to move. Through the movement of the outer baffle 18, the inner baffle 19 and the extension plate 20 will be pulled out to close the upper side of the storage tube 2 to prevent the finished powder from entering, thereby achieving the effect of adjusting the storage space inside the storage tube 2. When the cleaning plate 21 moves, it will produce friction on the inner wall of the storage tube 2 with the push of the spring 23, and then clean the inner wall of the storage tube 2, ensuring the convenience and safety of operation.

[0030] Working principle: When the N-phenylpyrrolidone finished product sampling device is needed, first pull the rotating sleeve 6 to slide on the outer wall of the outer shell 1, thereby driving the storage tube 2 to move out from one end of the outer shell 1, and then drive the connecting plate 5 to fit with the bottom of the outer shell 1, so that the lower side buckle 8 moves to the inside of the female buckle 4 at the bottom of the outer shell 1, to achieve the fixation of the connecting plate 5 and the storage tube 2, and then insert the storage tube 2 into the interior of the N-phenylpyrrolidone finished product powder. At this time, the finished product powder is filled into the storage tube 2 through the through hole on one side of the storage tube 2, and then the rotating sleeve 6 is rotated to fit on the connecting plate 5. The outer wall rotates, causing the limit block 11 to slide inside the rotating sleeve 6, and then drives the rotating rod 7 and the sub-button 8 to rotate through the sliding shaft 10. When the sub-button 8 rotates 90 degrees, the connecting plate 5 is no longer constrained, and then the storage tube 2 is pulled back to its original position, so that the sub-button 8 on the upper side of the connecting plate 5 moves to the inside of the female buckle 4 on the top of the outer shell 1, and the storage tube 2 is fixed again. At this time, the sealing baffle 3 will block the through hole of the storage tube 2, thereby realizing the storage of the finished powder, so that it can be carried and moved separately. Finally, the interior can be observed through the scale 12 and the perspective window 13;

[0031] In addition, the driving rotating seat 15 drives the telescopic rod 14 and the screw 16 to rotate, so that the partition plate 17 slides on the outer wall of the screw 16, and then the partition plate 17 slides on the inner wall of the storage tube 2. When the partition plate 17 moves, the outer baffle 18 and the cleaning plate 21 are driven to move. The movement of the outer baffle 18 will pull out the inner baffle 19 and the extension plate 20 to close the upper side of the storage tube 2 to prevent the finished powder from entering, thereby achieving the effect of adjusting the storage space inside the storage tube 2. When the cleaning plate 21 moves, the push of the spring 23 will form friction on the inner wall of the storage tube 2, thereby cleaning the inner wall of the storage tube 2.
