After the sucking disc 99 is being placed by five ribs 97 block at PCB board 2, personnel can be through pushing down sliding shaft 911, thereby make expansion plate 912 extrusion spliced pole 913, and then promote carriage 95 and outwards slide and then drive five ribs 97 and keep away from each other, thereby personnel can easily take off the PCB board 2 of placing on the sucking disc 99, take off and stop pressing sliding shaft 911, then under connecting spring 96's reset effect, five ribs 97, structures such as carriage 95 and sliding shaft 911 reset and resume to initial condition. The outer surface of the grip 45 is provided with anti-slip texture. Since the grip 45 has the anti-slip texture on the outer surface thereof, the grip 45 is less likely to slip when held by a person.
