[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention is provided with structures such as a servo motor and a lead screw.

[0017] 2. The present invention arranges structures such as pull rods and limit rods. When the movable seat approaches the fixed seat, the push rod will directly slide into the inside of the fixed rod. After the spring part is sprayed with magnetic powder, the movable seat moves backward again, and the top of the limit rod will clamp the fixed rod and pull it to one side. The fixed rod drives the square rod to move through the push rod, and the square rod also moves accordingly, so that the movable plate also moves downward, and the spring part will roll downward. When the push rod moves backward to the limit, the limit rod is also pushed downward, thereby sliding out of the inside of the fixed rod, and pops forward again due to the action of spring 1, so that the support rod also moves forward to block the spring part, and the baffle also rises accordingly to block the subsequent spring parts, so that loading and unloading do not require manual operation.

[0018] 3. The present invention has a base, a protective cover and other structures. Since magnetic powder will be emitted into the air when sprayed, it is easy to pollute the environment and affect the health of workers. Therefore, a protective cover is detachably fixed on the top of the base to prevent the magnetic powder from being emitted to the outside of the protective cover, and the protective cover is made of transparent material for easy observation.
