[0025] The screen quick fixing assembly 6 cooperates with the screen box 3 and the screen connection area 4 to form an inspection fixing area, and the screen 5 to be inspected is fixed in the fixing area by the screen quick fixing assembly 6 .

[0026] The screen quick fixing assembly 6 includes a connecting seat 61, a movable frame 62, a rotating connecting shaft 63, a handle 66, a locking spring 65 and a handle 66;

[0027] The connecting seat 61 is fixed to the side of the screen box 3, the movable frame 62 is installed on the outside of the connecting seat 61 through a rotating shaft, the rotating connecting shaft 63 is installed on the inside of the movable frame 62 through a rotating shaft, the fixed hook 64 is sleeved inside the rotating connecting shaft 63 and can slide vertically along the rotating connecting shaft 63, the locking spring 65 is sleeved outside the lower end of the fixed hook 64 and respectively contacts the bottom ends of the rotating connecting shaft 63 and the fixed hook 64, the handle 66 is fixed to the end of the movable frame 62, and one side of the screen box 3 is provided with through holes matching the number of the screen mesh quick fixing assembly 6, and the end of the fixed hook 64 passes through the through hole and enters into the screen box 3;

[0028] When fixing the screen 5, the movable frame 62 is driven to rotate by the handle 66, and the rotating movable frame 62 drives the end of the fixed hook 64 to move upward, and the end of the fixed hook 64 moves upward and passes through the through hole to extend into the fixed hole of the screen 5, and the handle 66 is pressed down. The handle 66 drives the movable frame 62 to rotate, and the rotated movable frame 62 drives the rotating connecting shaft 63 to rotate synchronously, and the fixed hook 64 in the rotating connecting shaft 63 rotates synchronously with the rotating connecting shaft 63. At the same time, the rotating connecting shaft 63 plays a downward pressing role on the locking spring 65, causing the locking spring 65 to deform and accumulate force, and the locking spring 65 pulls the fixed hook 64 downward, so that the end of the fixed hook 64 is in close contact with the screen 5. At the same time, the deformed locking spring 65 plays a role in limiting the position of the pressed movable frame 62, so that the movable frame 62 maintains the downward pulling and locking state of the fixed hook 64.
