摘要

Apparatus for training with tennis racket, characterized by being constituted by an arm composed of two telescopic sections, gradually extendable, whose base and point of support for its tilting mobility is embedded in a pin shaft inserted in the internal faces of a prismatic body, whose upper face has a slotted opening able to give free passage to the oscillating mobility of up to 90 degrees, to the said lever arm, said arm having its angularly curved upper end, to end up presenting on its tip the appropriate linkage of a tennis ball, which is the one that receives the impact of the racket.
