[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3, a multi-purpose fire extinguisher for fire fighting, comprising a tank body 1, a pressure handle 2 is installed at the top of the tank body 1, and a fixed handle 3 is connected to the inner side of the top of the tank body 1, the fixed handle 3 is connected to the pressure handle 2 through an elastic member, and the fire extinguishing agent can be output by holding the fixed handle 3 and the pressure handle 2 at the same time, a connecting pipe 4 is connected to the upper part of the outer wall of the tank body 1, and a nozzle 6 is installed at the other end of the connecting pipe 4, a collar 5 is sleeved on the outer wall of the connecting pipe 4, and a first pull rope 8 is connected to the outer wall of the collar 5, a block 9 is connected to the middle part of the first pull rope 8, the block 9 is arranged in a truncated cone structure, and the bottom diameter of the block 9 is equal to the inner diameter of the reserved hole 11, the first pull rope 8 is synchronously straightened with the traction of the connecting pipe 4, and the block 9 connected at the first pull rope 8 passes through the reserved hole 11, so that the block 12 can limit the block 9, and at this time, the pressure handle 2 and the fixed handle 3 are in a relatively pressed state, so the output of the fire extinguishing agent can be stably completed;

[0022] A reserved hole 11 is provided on the inner side of the fixed handle 3, and a stopper 12 is inserted into the interior of the fixed handle 3. The stopper 12 is slidably connected to the fixed handle 3, and there are two groups of stoppers 12. The stopper 12 is mainly used to limit the block 9 passing through the reserved hole 11. A spring 13 is connected to the end of the stopper 12, and the other end of the spring 13 is connected to the fixed handle 3. A second pull cord 14 is arranged on the inner side of the fixed handle 3, and one end of the second pull cord 14 is connected to the end of the stopper 12, and the other end of the second pull cord 14 is connected to a movable block 15, and the movable block 15 is movably connected to the fixed handle 3, and the movable block 15 forms an elastic connection with the fixed handle 3 through an elastic member. The movable block 15 forms a transmission structure with the block 12 through the second pull rope 14. When it is necessary to release the limiting operation of the block 12 on the block body 9, the movable block 15 is manually pressed down to pull the second pull rope 14 to move. Therefore, the second pull rope 14 can pull the block 12, and the block 12 is retracted into the fixed handle 3, which is convenient for the block body 9 to be separated from the reserved hole 11 and the pressure handle 2 to be reset. A sloped area 10 is provided on one side of the bottom end of the block 12, and a bearing seat 7 is connected to the lower part of the outer wall of the tank body 1, and the bearing seat 7 and the connecting pipe 4 are clamped. The bearing seat 7 is mainly used to place the connecting pipe 4, so that when the fire extinguisher is in a non-working state, the connecting pipe 4 is not easy to shake excessively.

[0023] Working principle: When in use, the staff first holds the fixed handle 3 with one hand and pulls the connecting tube 4 with the other hand, and pulls the connecting tube 4 off the bearing seat 7, and then stretches the connecting tube 4, so that the first pull rope 8 can be pulled, so that the block 9 connected to the middle of the first pull rope 8 passes through the reserved hole 11, and the block 12 is used to limit the block 9, so that the pressure handle 2 is in a stable traction state, and the auxiliary connecting tube 4 and the nozzle 6 output the fire extinguishing agent stably. Finally, by manually pressing the movable block 15, it pulls the second pull rope 14 to move, so the second pull rope 14 can pull the block 12, and the block 12 retracts into the fixed handle 3, so that the block 9 is convenient to be separated from the reserved hole 11, and the pressure handle 2 is convenient to be reset.
