The invention is driven by a small motor, thereby facilitating the random rotation of the cricket, thereby facilitating the use of different rubbers for catching the ball, and facilitating the improvement of students' judgment on the rubbers.

Description

technical field [0001] The invention relates to the field of sports, in particular to a rotary racket for table tennis training. Background technique [0002] During the table tennis competition, many players use the combination of positive and negative glue to play, so that many students are not used to it, and some use long glue and reverse glue alternately, so that students make misjudgments during the game.

Causes people to be caught off guard. During normal training, the teacher usually changes the rubber surface of the racket to catch the ball and let the students make judgments. However, it is slower when the surface of the racket is manually rotated, giving students enough time to judge, and never being able to strengthen the judgment. Random training with different rubber surface ball types, and it is tiring when turning the racket, and it is not convenient to quickly change the rubber surface of the racket. It takes a long time to train the rotation of the racket, which is troublesome. When the coach is not around , it is inconvenient for the students to train, because it is inconvenient for the students to master the skills of turning the racket, which brings inconvenience to the training of the students
