This invention provides a training gun with adjustable trigger force, comprising a gun body, a trigger, a connecting shaft, a
firing pin, and a striking element. It also includes a pressure adjusting component and an aiming unit. One end of the pressure adjusting component is threadedly connected to the connecting shaft via a first elastic element, used to adjust the trigger
pull force. The aiming unit is located on the
barrel of the gun body. This training gun realistically simulates the
impact force generated by trigger pull, changing the previous situation where training guns could only aim but not fire. Trainees can use this training gun to master the coordination of aiming, firing, and timing. During training, the aiming unit is activated, emitting a beam of light onto the target. The trainee pulls the trigger and observes the change in the beam's position on the target, thus achieving the training objective. Simultaneously, the pressure adjusting component can simulate the trigger force of various types of firearms, allowing training with this gun to achieve the purpose of training with various types of firearms.
