During the competition, appropriate scoring in accordance with the rules can increase the enthusiasm of each participant and improve the quality of the competition.
[0004] Traditional scoring methods for games mostly use simple scoreboards, and scores are scored by manually flipping the scoreboards. This scoring method requires personnel to supervise and control the scoring throughout the game, which takes up too much manpower and is prone to errors. When recording large data, it needs to be replaced, which is troublesome to operate. The scoreboard used to support the scoreboard is large in size, resulting in a large overall structure, which is inconvenient to carry and store, and occupies a large space. In addition, traditional scoring devices have poor stability. When used outdoors and encountering strong winds that blow the scoreboard, the support frame will shake, causing the scoreboard to break, affecting the game scoring, and it is inconvenient to transport and store the scoreboard and the bracket separately.
[0005] In view of this, the designer has made in-depth considerations on the many deficiencies and inconveniences caused by the imperfect structural design of the existing scoreboard, and has actively researched, improved and trial-made to develop the present utility model. Utility Model Content
