At present, a football positioning ball pass-through technology training and testing field usually draws three concentric circles on the football field by taking 2 meters, 3 meters and 4 meters as radiuses, inserts a marker post tied with a colored small flag at the center of the circle, then draws an arc line with the length of 5 meters from the center of the circle to any direction as a pass-through limiting line by taking the length of 25 meters (boy students) and 20 meters (girl students) as the radiuses; the positioning ball passing evaluation method comprises the following steps: the examinee places the ball on the restriction line, and passes the ball into the circle with either foot, and it is effective that the ball falls into or on the circle. The people with the radius of 2 meters in each kick get 6 points, the people with the radius of 3 meters in each kick get 4 points, the people with the radius of 4 meters in each kick get 2 points, and the people without the kick do not get points. The football positioning ball passing technology training and evaluation by adopting the small flag inserting and field drawing modes has the following defects: 1. the circle line on the field is generally marked by scattering white and gray on the field, and the circle line becomes fuzzy after being trodden for many times or blown by wind, so that the judgment of an examiner is influenced. 2. When each examinee tests, examiners must perform field visual measurement scores near the circle, the examiners can influence the aiming of the examinees when standing near the circle, and the examiners are hard. 3. The scores of examinees are determined by visual inspection of examinees, and the examinees are too subjective and easy to cheat. 4. The small flag in the middle of the bulls can influence the falling point of the football, and if the football is just hit on the flag, the score of the examinee can be directly influenced.

In view of the above problems, some solutions are disclosed in the prior art, such as patent numbers: 201420021747.0, with patent names: the Chinese invention patent of the football positioning ball accurate transmission mark ring discloses a method which comprises the following steps: a football positioning ball standard mark ring comprises a main structure of an outer ring wall, universal casters, an upper support, a lower support, a central pier, a mark rod, a mark ball and a ring net; wherein, outer lane wall lower extreme respectively with the one end fixed connection of six upper cradles and six lower cradles, the other end of six upper cradles respectively with central mound upper end fixed connection, the other end of six lower cradles respectively with central mound lower extreme fixed connection, central mound upper end and marker post lower extreme fixed connection, marker post upper end and marker ball lower extreme fixed connection, be equipped with the couple on outer lane wall, six upper cradles and the central mound respectively, connect the circle net on the couple, the circle net comprises the inner circle net of different colours, well circle net and outer lane net, outer lane wall lower extreme is equipped with a plurality of universal castor that take the standing valve. The football positioning ball aligning marker ring with the structure just solves the problem of marking, namely the first problem in the defects mentioned above. However, when the method is still practical, the three defects of the

problems

2, 3 and 4 still exist.

In conclusion, the prior art lacks an auxiliary football positioning ball pass-through tester which has clear boundary lines, is not easy to be worn, does not need examinees to observe visually, automatically inputs scores into a computer, has little influence on the scores by target mark and can effectively prevent cheating.
