Background
In the field of fire fighting, the starter of a non-pressure storage type fire extinguisher is mostly of a pure mechanical type, a pure electric starting type or a mechanical and electric combined type, and the existing starter has a single starting mode, so that the reliability is low. In the face of the change of the installation environment, the types of the starters required by field installation are different, and the existing starter generally cannot be provided with more than two starting modes at the same time, which is not beneficial to large-scale and standardized production of the starter.

The striker 30 is cylindrical in shape, and a pin hole 80 is formed at one end of the striker 30, and a central axis of the pin hole 80 is perpendicular to a central axis of the striker 30. The other end of the striker 30 is integrally formed with a circular stopper piece 301. One end of the piston pin 31 is shaped to fit into the pin hole 80 of the striker 30 and enables the piston pin 31 to be detachably coupled to the striker 30. The other end of the piston pin 31 is positioned in the second mounting opening 12, and the diameter of the other end of the piston pin 31 is the same as the caliber of the second mounting opening 12. An annular groove 311 is formed on the outer wall of the other end of the piston bolt 31, the rubber ring 35 is sleeved on the other end of the piston bolt 31, and the rubber ring 35 is located in the annular groove 311.
