[0015] 3. The utility model generates a magnetic force on the iron sheet by energizing the electromagnet, so that the connecting rod drives the fixing pin to be retracted into the first mounting hole, so that the upper connecting block is separated from the lower connecting block, thereby opening the sealing cover, closing the sealing cover, and inserting the lower connecting block into the upper connecting block. When the inclined surface contacts the inner wall of the upper connecting block, the fixing pin is retracted into the first mounting hole. When the lower connecting block is fully inserted into the upper connecting block, the reset spring pushes the fixing pin to insert the fixing pin into the fixing hole, thereby fixing the lower connecting block. The operation is simple and is conducive to improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
