The invention relates to a sport apparatus, in particular to a rotary snapline type ball picking device. The rotary snapline type ball picking device comprises a handle, brackets, elastic lines, line-fixing discs, lantern rings, gaskets and shaft discs. The L-shaped brackets are respectively fixed on both sides of the lower end of the cylindrical handle, and the lower ends of the two brackets arerespectively welded with the annular lantern rings. Rotating shafts of the shaft discs and the line-fixing discs form stationary-fit relationship, the gaskets are sleeved on the rotating shafts of theshaft discs, and the lantern rings are sleeved on the gaskets. The line-fixing discs are in a flat cylindrical shape, a plurality of through holes are distributed on the edge of the line-fixing discsin an equal circumference mode, and both ends of a plurality of mutually parallel elastic lines distributed in a circumference shape are respectively fixed in the through holes of the two line-fixingdiscs. Because ping pong can be collected only by rolling, the invention greatly enhances the efficiency of ball picking, and physical force and the time of athletes are saved in the training of theping pong.
