The limiting sheet 672 is separated from the strip-shaped limiting groove 673 after moving to the strip-shaped mounting hole 81, and the limiting sheet 672 rotates in the strip-shaped mounting hole 81; the limiting sheet 672 contacts with the limiting member 82 in the rotating process, and the limiting sheet 672 presses against the limiting member 82 through the third inclined surface 83 and pushes the limiting member 82 to move upwards.

One embodiment of the present embodiment comprises the steps of attaching the bottom surface of the frame of the mesh sheet to the top surface of the strip-shaped plate 11, placing the square box 21 above the base to be installed with the mesh sheet, fixing the square box 21 on the surface of the base by screwing the fixing screw 3, and driving the U-shaped frame 14 to move downward during the rotation of the fixing screw 3. The connecting plate 15 moves downward relative to the bearing plate 22, and the bearing plate 22 applies upward supporting force to the mesh frame. In the process that the bearing plate 22 moves upwards relative to the connecting plate 15, the second pressing piece 56 moves upwards along with the bearing plate 22, the second pressing piece 56 presses and pushes the first pressing piece 55 to move towards the side far away from the bearing plate 22, the first pressing piece 55 presses and pushes the abutting groove 58 through the first inclined surface 59, and the first pressing piece 55 pushes the plug connector 53 to move towards the side close to the square box 21; after the plug member 53 is separated from the bar-shaped insertion hole 51, the insertion plate 43 is inserted into the bar-shaped insertion groove 41 by the elastic force of the first return spring 44. When the extending seat 65 moves upwards relative to the vertical plate 12, the rotating round pipe 66 moves upwards relative to the rotating shaft 64; the spiral groove presses the spiral protrusion 642 upwards and applies a rotating torque to the spiral protrusion 642, so that the rotating shaft 64 is driven to rotate by rotating the circular tube 66, the rotating shaft 64 drives the second bevel gear 641 to rotate through the first bevel gear 621, and the second bevel gear 641 drives the screw 67 to rotate through the first connecting shaft 62; under the limit of the guide assembly 7, the screw 67 drives the connecting plate 15 to move towards the side close to the top plate 13. After the net piece frame is arranged, the connecting plate 15 is folded towards one side close to the net piece frame, one side of the baffle plate 16 close to the connecting plate 15 is attached to one side of the net piece frame away from the vertical plate 12, and the net piece frame is limited through the baffle plate 16. The connecting plate 15 drives the second connecting shaft 71 to move, the second connecting shaft 71 is in contact with the arc-shaped plate 77 and then pushes the second inserting block 78 to move towards the side far away from the connecting plate 15, and the second inserting block 78 is separated from the second square slot 79; the first insertion block 74 is inserted into the first square insertion groove 75 by the elastic force of the third return spring 76, thereby limiting the second connection shaft 71.
