[0008] Preferably, the limiting mechanism includes a limiting rod, a through hole is opened at the top of the installation box, the limiting rod is movably inserted into the inside of the through hole, the lower end of the limiting rod is set as a wedge-shaped end face and is movably plugged into the corresponding limiting groove, and the limiting of the rectangular frame can be achieved by plugging into the corresponding limiting groove. At the same time, the wedge-shaped end face set at the lower end of the limiting rod can enable the rectangular frame to be freely flipped upwards.

[0009] Preferably, the rod wall of the limit rod fixes the limit plate, and a spring movably sleeved with the rod wall of the limit rod is fixedly connected between the upper surface of the limit plate and the inner wall of the installation box. By utilizing the set spring, the limit plate can be squeezed by the elastic force of the spring, so that the limit rod can maintain a stable plug-in state with the corresponding limit groove when there is no external force.

[0010] Preferably, a driving block is fixedly connected to the upper end of the limiting rod, and the provided driving block can be used to drive the limiting rod to move, so as to move the limiting rod out from the inside of the corresponding limiting groove.

[0011] Preferably, a bellows movably sleeved with the rod wall of the limiting rod is fixedly connected between the driving block and the installation box. The provided bellows can be used to seal the through hole position to prevent oil smoke from entering the interior of the installation box.
