[0020] Please see Figures 1-3In this embodiment of the present invention, a multifunctional vehicle-mounted simple water-based fire extinguisher includes a pressure-resistant tank 1, which is filled with a water-based fire extinguishing agent and a propellant (usually compressed nitrogen or compressed carbon dioxide). A valve is fixedly installed inside the opening of the pressure-resistant tank 1. The medium inlet of the valve is located inside the pressure-resistant tank 1, and a drain pipe is fitted on the medium inlet. The medium outlet of the valve is located outside the pressure-resistant tank 1, and a nozzle 3 is fixedly fitted on the medium outlet. A cap 2 is fixedly fitted on the outside of the opening of the pressure-resistant tank 1. The nozzle 3 is slidably installed inside the cap 2. A nozzle 4 is provided at the front end of the nozzle 3.

[0029] When the safety cover 8 is pushed off the window breaker bar 7 using the lever 12, the force can be transmitted through the cooperation of the slot 15 and the insert 14 to prevent the blade 11 from being directly subjected to the force from the lever 12.

[0030] Specific combination Figure 3 Furthermore, based on the previous embodiment, both the safety cover 8 and the lever 12 are produced by injection molding. The inner walls of the openings on both sides of the opening groove 10 are provided with positioning grooves 17. The lever 12 is integrally formed with positioning protrusions 16 at the corresponding positions of the positioning grooves 17. The positioning protrusions 16 are adapted to the size of the positioning grooves 17.

[0031] By setting the positioning groove 17 and the positioning protrusion 16, the lever 12 can be positioned on the safety cover 8 to prevent the lever 12 from falling out of the opening groove 10 without human operation, and the lever 12 can be pulled out of the opening groove 10 by simply pulling it.

[0032] Specific combination Figure 2 In one embodiment of this utility model, the bottle cap 2 is provided with a movable groove 5 and a pressing groove 6. By setting the movable groove 5 and the pressing groove 6, interference with the movement of the nozzle 3 can be avoided when pressing the nozzle 3.
