This application can detect the pressure value during hot-melt connection, which is convenient for people to accurately control the connection pressure at the molten end faces of the two pipe fittings, improve the stability of the hot-melt quality, and at the same time, it can try to prevent the digital pressure gauge from being damaged due to excessive instantaneous impact force.
