The upper end of the two racks 5 away from the connecting rod 3 is fixed with a first connecting block 9. A spring 10 is connected between the first connecting block 9 and the second connecting block 11. A convex plate is fixed on the side of the two fixed blocks 6 away from each other.

[0027] Specifically, stacking multiple loading trays 1 inside the housing 2 is beneficial to preventing the turnover fixture from shifting during the transfer process, causing damage to the semiconductor devices; pulling the connecting rod 3 drives the rack 5 to move, and the rack 5 drives another rack 5 to move through the gear 8, which is beneficial to driving the two connecting rods 3 away from each other, thereby driving the two fixing columns 4 away from each other, and then disengaging from the fixing holes 13, making it convenient to adjust the height of the fixing block 6; the moving convex plate drives the fixing block 6, the connecting rod 3 and the fixing column 4 to move. When the fixing column 4 is aligned with different fixing holes 13, the spring 10 pulls the No. 1 connecting plate 15, driving the rack 5 to move, so that the two racks 5 return to their original position, and then driving the fixing column 4 to insert into the fixing hole 13, which is beneficial to fixing the fixing block 6 at different heights, aligning the No. 1 groove 7 with the loading tray 1, and taking out the loading trays 1 of different heights. There is no need to take out the loading trays 1 one by one, which is beneficial to improving work efficiency and reducing the workload of users.

[0028] Reference Figure 3 、 Figure 4, a grid disk 101 is fixedly provided at the upper end of the main body 102, and a No. 1 convex strip 103 is fixedly provided on both sides of the upper end of the main body 102, and two protrusions 104 are fixedly provided on the front side of the upper end of the main body 102, and a No. 2 convex strip 105 is fixedly provided on both sides of the lower end of the main body 102, and a No. 2 groove 106 is provided at the lower end of the two No. 2 convex strips 105.

[0029] Specifically, when multiple loading trays 1 are stacked on each other, the two No. 2 ridges 105 of the upper loading tray 1 and the two No. 1 ridges 103 of the lower loading tray 1 will be locked together, which helps to prevent the grid tray 101 from being squeezed and thus damaging the internal semiconductor devices; when pulling the loading tray 1, when the grid tray 101 is pulled out of the shell 2, the protrusion 104 will block the No. 2 ridge 105, preventing the loading tray 1 from being completely pulled out, causing the upper loading tray 1 to fall downward; at the same time, the part of the main body 102 that is more than the grid tray 101 is located between the two loading trays 1, which helps to prevent the loading tray 1 from tilting to one end.

[0030] Working principle: When the device is in use, the semiconductor device is placed inside the grid disk 101, and then multiple grid disks 101 are stacked up and placed inside the shell 2, which is beneficial to avoid multiple loading disks 1 being stacked together and offset during transportation, resulting in damage to the semiconductor device. When taking out the loading disk 1, the loading disk 1 can be taken out from top to bottom in sequence. In addition, the connecting rod 3 can also be pulled, and the connecting rod 3 drives the rack 5 to move. The rack 5 moves the other rack 5 in the opposite direction through the gear 8, driving the two connecting plates 15 away from each other, so that the two fixing columns 4 are disengaged from the fixing holes 13, and then the fixing block 6 is pulled to fix the fixing columns 4 inside the fixing holes 13 at different heights, so that the No. 1 groove 7 is aligned with different loading disks 1, and then the loading disk 1 aligned with the No. 1 groove 7 is pulled out of the shell 2, and the semiconductor device inside it can be taken out. There is no need to take out the loading disks 1 one by one, which is beneficial to improve work efficiency and reduce user consumption.
