Ultimately, it can not only provide shielding for the staff during maintenance, but also be more convenient in use.
[0015] Secondly, the utility model provides a cabinet, a shielding cross bar and an expansion top plate and their respective objects. When it is necessary to expand the shielding range, the positioning rod can be manually pulled to make the bevel block away from the inside of the expansion slide slot through the connecting part, so that the sliding block is no longer blocked by the bevel block. Since the expansion slide slot is in an inclined state, the expansion top plate and the connecting plate will be expanded outward. When it is necessary to retract, the expansion top plate can be pushed to make the sliding block slide inside the expansion slide slot. When sliding to the bevel block, the bevel block will be pushed to both sides, and then the expansion top plate will be retracted under the rebound of the spring part. Finally, not only can the shielding range be expanded, but the operation is also simple. BRIEF DESCRIPTION OF THE DRAWINGS
