Description

Technical Field

[0001] This utility model belongs to the field of detection technology, and in particular relates to an intelligent measuring device for trigger characteristics. Background Technology

[0002] Shooting stability is a core factor determining shooting accuracy and competitive level. It depends on the shooter's psychological and physiological stability and is closely related to trigger force control. The magnitude and variation of trigger force directly affect the shooter's muscle control, action timing, and firing accuracy; therefore, precise measurement and optimization are of great significance. Current shooting training lacks intelligent devices capable of real-time and precise measurement of parameters such as trigger force, trigger travel, and pulling speed. This not only limits data analysis in athletes' technical training and scientific guidance from coaches but also hinders the improvement and quality enhancement of shooting equipment in training performance. Therefore, there is an urgent need for a device capable of intelligently and precisely measuring trigger characteristics to improve the scientific level of shooting training and competitive performance.
