The battery 15 energizes the coil 19 in the magnet 17 through the connecting line 18, so that the magnet 17 can generate a strong adsorption force to firmly absorb the piston 13 in the box groove 29. Finally, the magnetic attraction mechanism is driven by the rotating mechanism to return to the top of the clamping mechanism, and then the hydraulic cylinder 16 on the magnet 17 is started to lift the piston 13, so that the piston 13 can be accurately placed in the piston cylinder. When the piston 13 is placed, the piston 13 can be released by simply deenergizing the coil 19 in the magnet 17.
