Then, the finger cylinder 52 drives the two unlocking blocks 53 to move toward each other, so that the two positioning pins 44 move toward each other and the two locking pins 45 move toward each other. Then, the carrier pressing plate 41 is driven to move downwards by the pressing plate cylinder 23, so that the two positioning pins 44 are pressed against the lining plate, and the locking pins 45 are inserted into the locking slots 461. Finally, the unlocking block 53 is reset by the movable air cylinder 51 and the finger air cylinder 52.

The magnet lifting assembly 72 drives the magnet material taking rod 63 to drive the round magnet to move downwards again, so that the lower end of the round magnet moves into the space between the three hooks. The secondary magnet transverse moving component 71 drives the circular magnet to transversely move, and the circular magnet is pressed against one or two hooks, so that the hooks are outwards deformed and bent. Then move round magnet down through magnet lifting unit 72, rethread magnet is got material cylinder 61 and cylinder connecting block 62 drive magnet and is got material pole 63 and reset to vertical to make round magnet reset. Then the magnet transverse moving component 71 drives the magnet material taking rod 63 to move, so that the round magnet presses the rest hooks to deform and bend outwards. Finally, the top magnet rod 64 is pushed to move downwards by the top magnet cylinder 66, so that the round magnet is pushed out of the magnet groove 631 and is completely pushed into the magnet jaw. The return spring 65 performs a return function so that the top magnet rod 64 can be returned after the circular magnet is ejected out of the magnet groove 631.

Through above-mentioned structure for when circle magnet installation, circle magnet is difficult for pressing on three pothook and lead to three pothook all not to take place the deformation bending because of supporting simultaneously, helps the installation of circle magnet, thereby has improved the packaging efficiency of gas valve.
