According to the fact that the deeper the bottom of the gun head is pressed, the larger the reaction force is, and the larger the pressure applied to the pressure sensor is. At this time, when the cloth tension is equal to the reaction force, the current base cloth tension value can be indirectly read through the pressure sensor.
