Pressing plate isolation sealing tool

The invention discloses a pressing plate isolation sealing tool, and relates to the technical field of pressing plate protection. The sides, close to the opening end of the U-shaped shell, of the two inner side walls of the U-shaped shell abut against a base of the wire spring type pressing plate, and strong magnets are oppositely arranged on the two inner side walls of the U-shaped shell. The sides, away from the opening end of the U-shaped shell, of the two inner side walls of the U-shaped shell are each provided with a fixing block, and each fixing block is provided with an inclined face. The inclined faces of the two fixing blocks are oppositely arranged in parallel, and a connecting piece groove is formed between the two fixing blocks in the opposite direction and used for containing a connecting piece of the wire spring type pressing plate. A protection column is arranged on the side, facing the opening end, of the fixing block and used for being connected with an electrode insertion hole of the wire sp
