The thickness of the limiting plate 2 corresponds to the distance between the upper and lower surfaces of the U-shaped groove 4. The limiting plate 2 is at the same height as the U-shaped groove 4.

[0017] When the right ends of the two limiting plates 2 of the left side grid body 1 contact the right side of the U-shaped groove 4 of the right side grid body 1, the right side of the left side grid body 1 contacts the left side of the right side grid body 1. The slot 3 of the front limiting plate 2 is located in front of the front card plate 6, and the slot 3 of the rear limiting plate 2 is located behind the rear card plate 6.

[0018] The driving component includes a rotating rod 10 and a screw 17. A vertical plate 11, fixed within a U-shaped groove 4, is provided between the two connecting plates 5. The vertical plate 11 is a rectangular plate whose upper and lower ends are respectively connected to the upper and lower sides of the U-shaped groove 4. There are two vertical plates 11, and a rotating rod 10 is rotatably connected between the two vertical plates 11. A bevel gear 12 is sleeved and fixed on the rotating rod 10. A torsion spring 18 is sleeved on the rotating rod between the bevel gear 12 and the inner bottom of the U-shaped groove. One end of the torsion spring is connected to the peripheral wall of the rotating rod, and the other end is connected to the inner bottom of the U-shaped groove. A screw 17 is rotatably connected to each vertical plate 11. The threads on the two screws 17... With the same rotation direction, the opposite ends of the two screws 17 are connected to bevel gears 13, and both bevel gears 13 mesh with bevel gears 12. The opposite ends of the two screws 17 are threaded to the connecting plates 5 at the front and rear of the U-shaped groove 4. The small end of bevel gear 12 faces downward, and the large ends of the two bevel gears 13 are connected to the corresponding screws 17. Each upright plate 11 has a retaining ring 16 sleeved on the corresponding screw 17 on its front and rear sides, and both retaining rings 16 slide in contact with the corresponding upright plate 11. When the two connecting plates move to their limit relative to each other, the two clamping plates are located on the right side of the baffle.

[0019] When the torsion spring 18 is in its natural state, the two retaining plates in the U-shaped groove are located on the front and rear sides of the baffle, respectively; the upper end of the rotating rod 10 passes through and is rotatably connected to the grille body 1; the upper end of the rotating rod 10 is provided with a straight groove 15, and the upper end of the rotating rod 10 is flush with the top surface of the grille body 1; the lower end of the rotating rod 10 contacts the inner bottom of the U-shaped groove 4; a limiting rod 14 is fixedly installed on the rotating rod 10 located in the U-shaped groove 4, and the two ends of the limiting rod 14 are located outside the rotating rod 10, with the upper end of the limiting rod 14 extending outside the rotating rod 10 slidingly contacting the inner top surface of the U-shaped groove 4.

[0020] When connecting the two grille bodies 1, firstly, insert the end of a flathead screwdriver into the slot 15 of the rotating rod 10 on the right grille body 1 to drive the rotating rod 10 to rotate.

The bevel gear 13 on the rear screw 17 is engaged by the bevel gear 12, and the rear screw 17 rotates in the opposite direction to the front screw 17 with the connected bevel gear 13. Since the threads on the two screws 17 have the same direction of rotation, rotating the rotating rod 10 in the forward direction can drive the two connecting plates 5 to move relative to each other, and rotating the rotating rod 10 in the reverse direction can drive the two connecting plates 5 to move in opposite directions. Based on this, rotating the screw 17 causes the two connecting plates 5 to move relative to each other, and the torsion spring 18 is twisted until the two connecting plates 5 are connected. Plate 6 is located in the U-shaped groove 4 on the right side of baffle 8, keeping the rotating rod stationary; then, the two limiting plates 2 on the left grille body 1 extend into the U-shaped groove 4 of the right grille body 1 through the front and rear sides of baffle 8 of the right grille body 1, until the right end of each limiting plate 2 contacts the right side of the U-shaped groove 4. At this time, the right side of the left grille body 1 contacts the left side of the right grille body 1, the slot 3 of the front limiting plate 2 is located in front of the front locking plate 6, and the slot 3 of the rear limiting plate 2 is located in front of the rear locking plate 6. Then, the screwdriver releases the limiting of the rotating rod 10. Under the restoring force of the torsion spring, the torsion spring drives the rotating rod to rotate in the opposite direction. At this time, the two connecting plates 5 move in opposite directions, and the locking plate 6 on each connecting plate 5 moves toward the slot 3 on the limiting plate 2 on the same side, until the locking plate 6 extends into the corresponding slot 3 and limits the limiting plate 2. At this time, the connection of the adjacent grille bodies 1 is completed.
