The ball striking of the volleyball is a very important technical link of volleyball technology, is also an important means for scoring, and is a very difficult technical action to master. In daily teaching, people often practice by beating the hanging ball (namely stretching and fixing two ends of the ball by using rubber bands), but the hanging ball is firstly difficult to find a place to fix and inconvenient to lift, and secondly the hanging ball shakes greatly and does not have continuity, and more importantly, the hanging ball cannot see the effect of buckling the ball. The existing volleyball smash auxiliary equipment generally performs smash training by falling off at fixed points of volleyball at high positions. However, the above scheme still has a certain defect, and researches show that the coming ball route of the actual playing field is generally parabolic, the playing field is generally used for repairing and playing the ball through step transfer, and the playing ball cannot be simulated by the falling of the fixed point, so that the playing ball training effect is poor.

A volleyball smash aid is disclosed in the prior art publication CN215351906U, and includes a volleyball assembly and a roll-off assembly. The rotation rate of adjustment driving motor controls the screen frame to rotate, allows the volleyball to pass through when the screen frame is horizontal to control the whereabouts frequency of volleyball, the volleyball falls to the guide cage in last through closing the guide cylinder steady whereabouts, when needing the simulation ball pitch arc, the pneumatic cylinder control is led cage and guide cylinder and is swung by a small margin from top to bottom, the operation parabola of volleyball when simulating the smash, opens swivel work head control volleyball and throws the mouth and rotate, the volleyball trains through the step in running, when making things convenient for the volleyball dead weight to fall, carries out throwing ball accuracy training to the volleyball, the training of smash is more convenient. However, in an actual match, a ball is generally thrown to a ball catcher by two passes, the ball is often in arc motion rather than in vertical direction, a conventional auxiliary device cannot simulate the actual arc motion of the ball catcher, meanwhile, the ball catcher is driven by a rotating rod or a spring to serve the ball, the operation is difficult, a coach cannot change the launching angle and time of the ball catcher at any time, the training mode cannot be flexibly adjusted according to personal conditions, and effective training cannot be achieved.
