[0039] Working principle: When the present invention is used, when testing electrical grade magnesium oxide particles, the electrical grade magnesium oxide particles are first placed in the placement box 4, and then the electric push rod 27 is turned on, and the rectangular frame 16 is driven to move by the contraction of the movable end of the electric push rod 27, and the movement of the rectangular frame 16 is divided into two processes:

[0040] Process 1: Under the action of the extrusion spring 17, the movable block 23 moves synchronously with the rectangular frame 16, thereby driving the bar-shaped toothed plate 18 to move, thereby driving the gear 19 to rotate, and further driving the connecting shaft 24 to rotate. The rotation of the connecting shaft 24 drives the connecting plate 2 to rotate, and then drives the sleeve 12 and the rectangular plate 29 to rotate, thereby driving the placement box 4 to rotate. When the sleeve 12 contacts the limiting plate 3, the placement box 4 rotates 90°;

[0041] When the placement box 4 rotates, the short cylinder 26 enters the arc groove 901. When the placement box 4 rotates 90°, the short cylinder 26 moves to the end of the return groove 902. At the same time, the second push rod 20 contacts the sliding plate 8.

[0042] When the sleeve 12 rotates, it drives the connecting rod 14 to rotate, and the connecting rod 14 moves upward along the top rod 5, thereby driving the fixing rod 30 to move upward. When the placement box 4 rotates to 90 degrees, the fixing rod 30 just disengages from the fixing hole, releasing the fixation of the rectangular plate 29.

[0043] Process 2: As the rectangular frame 16 continues to move, the push rod 20 will be driven to move, and then the sliding plate 8 will be driven to move, so as to push the slideway 15, and then the placement box 4 will be driven to move, thereby driving the short cylinder 26 to move, and the placement box 4 will move back and forth along the return groove 902 by the short cylinder 26, so that the electrical grade magnesium oxide particles in the placement box 4 move, and then the electric push rod 27 is controlled to make the short cylinder 26 move back and forth along the return groove 902 until the electrical grade magnesium oxide particles are flattened;

[0044] Then, the rectangular frame 16 is moved further, and the short cylinder 26 is moved along the straight groove 903, and finally the placement box 4 is moved to the bottom of the laser particle size analyzer body 6, and then the uniformity of the electrical grade magnesium oxide particles is detected by the laser particle size analyzer body 6;

[0045] After the uniformity of the electrical grade magnesium oxide particles is detected, the movable end of the electric push rod 27 is controlled to extend to drive the rectangular frame 16 to reset, and then the sliding plate 8 is reset under the action of the second extrusion spring 21, and then the placement box 4 is reset under the action of the first tension spring 28; wherein, when the placement box 4 is reset, when the short cylinder 26 moves to the end of the arc groove 901, the fixing rod 30 is inserted into the fixing hole under the action of the second tension spring 31 to fix the rectangular plate 29; finally, the placement box 4 is reset to the front end surface of the workbench 1;

[0046] When cleaning the electrical-grade magnesium oxide particles in the placement box 4, first remove the sealing plate on the placement box 4, and then push the cleaning plate 25. The movement of the cleaning plate 25 pushes the electrical-grade magnesium oxide particles in the placement box 4 to flow out from the discharge port, making it easy to quickly clean the electrical-grade magnesium oxide particles in the placement box 4.

[0047] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
