2 tops of montant are equipped with horizontal pole 22, and horizontal pole 22 upside is equipped with two linear guide 23 that are parallel to each other, one of them linear guide 23 with mount pad 3 sliding connection, slidable mounting has balancing weight 291 on another linear guide 23, linear guide 23's both ends are equipped with band pulley 24, two install round belt 29 on the band pulley 24, in the belt 29 one with mount pad 3 fixed connection, another and balancing weight 291 fixed connection in the belt 29, band pulley 24 is connected with driving motor 25, driving motor 25 is connected with battery 32, control panel 21 electricity. When the embroidery ball is thrown for practice, a practitioner can start the driving motor 25 through the control panel 21 to rotate forwards and backwards, the belt 29 on the belt wheel 24 drives the mounting seat 3 and the color rings on the mounting seat to move leftwards and rightwards on the linear guide rail 23, the practice difficulty is further improved, the playing methods of games can be enriched, the ornamental value and the entertainment value of the games are enhanced, meanwhile, the counter weight block 291 and the mounting seat 3 move relatively to carry out gravity balance, and the phenomenon that the center of gravity of the embroidery ball frame moves to turn on one side is avoided.

A 180-degree turnover base 26 is arranged between the cross rod 22 and the vertical rod 2, a steering engine 27 for driving is arranged on the 180-degree turnover base 26, and a transverse electric telescopic rod 28 is arranged on the lower side of the cross rod 22. The control panel 21 can start the steering engine 27, turn down the color ring by 180 degrees through the 180-degree turning base 26, and then control the transverse electric telescopic rods 28 at the two sides to extend out to serve as a height standard when throwing the embroidery ball, and if the throwing of the embroidery ball does not reach the height of the throwing of the embroidery ball, the judgment fails.

The holder 4 overcoat still is equipped with ripple protective case 43, can protect, avoids drenching with the rain to make the equipment rust, and the edge of ripple protective case 43 twines the colored ribbon, and is more pleasing to the eye.

The ball embroidering frame is further provided with a set of video monitoring system 6 comprising a wind driven generator 61, a camera 62, a dividing screen 63, a storage unit 64, a display 65 and a control unit 66, the camera 62 is located near the vertical rod 2 and used for shooting images of ball embroidering movement, the dividing screen 63 is arranged on the vertical rod 2 and used for displaying the dividing, the storage unit 64 and the display 65 are arranged on the background and are integrally connected to the control unit 66, the control unit 66 is wirelessly connected with the control panel 21 through a wireless module transceiver module 67, the camera 62 collects video images at a ball throwing ring in real time and wirelessly transmits video image data to the background to be stored in the storage unit 64, a worker checks the field images through the display 65 and uses the control unit 66 to beat the dividing screen 63 of the two parties to ensure the accuracy of ball entering statistics, the wind generator 61 may power the battery 32, the score screen 63 and the camera 62.

The vertical rod 2 can further adopt a lifting rod structure, and the ball throwing height can be adjusted when basic action exercise is carried out, so that the principle that the ball throwing distance is from near to far from low to high is followed, and the exercise quality of an exerciser is improved.

The structure and function of the ball embroidering frame of the invention are further explained in combination with the competition method.

The competition method 1: when a match is played, an embroidery ball rack is erected in the middle of the field, a referee starts the steering engine 27 through the control panel 21, turns down the color ring for 180 degrees through the 180-degree turning base 26, and then controls the transverse electric telescopic rods 28 on the two sides to extend out to serve as a height standard when the embroidery ball is thrown, and the referee fails when the height of the thrown embroidery ball is not reached. In the game, when the players throw the embroidery ball, the embroidery ball is thrown in different predetermined postures, for example, the first round is thrown with one hand on the side, and the second round is thrown with the back. The team member of the catching team needs to clearly see the appearance of the embroidery ball, select the position and the angle for catching the embroidery ball and have an elegant catching posture, if the team member can catch the embroidery ball, the catching party wins, otherwise, the throwing party wins. The winner can remove a team member who has lost the winner, and then the winner can serve the ball. And rotating in turn until one party is 'full army coverage' and the competition is finished.

The competition method 2: increasing difficulty on the basis of the match method 1, starting a steering engine 27 by a referee through a control panel 21, turning up the color ring by 180 degrees through a 180-degree turning base 26, and throwing the ball from the color ring by a ball throwing party, otherwise, failing to throw the ball, automatically rejecting a player, and keeping the other rules unchanged.

The competition method 3: increasing difficulty on the basis of the match method 2, in the ball throwing process, the judge can reduce the diameter of the color ring once after throwing the ball for a plurality of times, the ball throwing party must throw the ball from the color ring, otherwise, the ball throwing party fails, one player is automatically rejected, and the judge can determine whether to further reduce the color ring of the loser, and other rules are unchanged.

The competition method 4: increasing difficulty on the basis of the match method 2, a judge can start the driving motor 25 to rotate forwards and backwards, drive the mounting seat 3 and the color ring on the mounting seat to move left and right on the linear guide rail 23 through the belt 29 on the belt wheel 24, and throw the ball from the color ring by the ball throwing party, otherwise, the ball throwing party fails, one team member is automatically rejected, and other rules are not changed.
