PROBLEM TO BE SOLVED: To provide an adjustable collision trigger device and a method of adjusting trigger. SOLUTION: This invention is related to the adjustable collision trigger device and a method of adjusting trigger, and the adjustable collision trigger device of this invention includes a power source supply module, an electronic acceleration sensor module and a microcomputer control module. The microcomputer control module includes at least an immediately processing unit and a beacon operation instruction unit. A determination whether or not a moving material will collide is made by the described device and other method, and in the case wherein a collision is determined, an emergency injecting device is operated for positioning in relation to the moving material. The device of this invention is an electronic device capable of performing three-axis determination at once. A critical acceleration value thereof is adjusted based on mode of the moving material so as to improve sensibility and so as to reduce incorrect report ratio and losing effect ratio of the device.
