The utility model provides an overhead paddle trapping apparatus. The device includes: hollow have a first cylinder of magnetic, has magnetic baffle, pin and magnet piece, wherein, first cylinder bothends are open structure, first cylinder inner wall is equipped with first recess, the baffle with the size phase -match of first recess, the one end of baffle is passed through the pin with the one end of first recess is connected, the other end of baffle passes through the adsorption of magnet piece fixes the other end of first recess, the magnet piece is located on the outer wall of first cylinder. Because whole baffle moves crosswise on first cylinder inner wall, strengthen the hindrance effect to the plunger downstream among this overhead paddle trapping apparatus, improved the success rate of catching the plunger.
