Description

Technical Field

[0001] The utility model relates to the field of sports equipment, in particular to a table tennis racket for practicing swing speed. Background Art

[0002] The functions of practicing swing speed in table tennis mainly include: 1. Improving skills: Swing speed is one of the key elements of table tennis technique. By increasing the swing speed, the player's reaction and control abilities can be improved; 2. Strengthening muscle strength: The increase in swing speed requires rapid muscle contraction. Swing speed training can enhance muscle strength and endurance; 3. Improving the ball path: The increase in swing speed can make the ball's flight arc smoother, thereby improving the ball path and improving the ball's controllability and stability. Therefore, improving the swing speed plays an important role in table tennis practice. Currently, there are table tennis rackets that can reflect the swing speed, such as the Chinese patent with application number CN201720972086.3, which discloses a new handle of a table tennis racket, including a sensor module for testing the swing speed and collecting user information, and the swing speed can be monitored through the sensor module. Although the current table tennis rackets of this type can detect the swing speed, different people and different exercise periods need to adjust the racket weight according to their usage habits during practice. The current table tennis rackets that can practice the swing speed cannot adjust the weight according to the needs, and the versatility of use is poor. The weight cannot be adjusted according to the needs to meet different training requirements. Utility Model Content
