[0006] As a further improvement of the utility model, the driving module comprises sliding cylinders which are uniformly rotatably arranged on the two sides of the support, the interiors of the sliding cylinders are both slidably provided with sliding columns, the ends of the sliding columns away from the sliding cylinders are respectively rotatably connected with adjacent sliding rods, and springs are arranged between the interiors of the sliding cylinders and the sliding columns; a plurality of positioning holes are arranged on the front side of the front side of the arc-shaped seat, and positioning pins are respectively inserted between the sliding rods and adjacent positioning holes.

[0007] As a further improvement of this utility model, a rotating reel is rotatably arranged on the side of the movable frame away from the rotating seat, and a fire hose is wound on the rotating reel. A conveying pipe is arranged between the rotating reel and the movable frame, and the conveying pipe is connected to the fire hose. A nozzle is arranged at the end of the fire hose away from the rotating reel, and a water inlet is arranged at the end of the conveying pipe away from the rotating reel.

[0008] As a further improvement of this utility model, the middle part of the clamping wheels is fitted with an elastic rubber sleeve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] First, rotate the reel to wind up the fire hose. Then, personnel pull out the positioning bolts on both sides to unlock the sliding rod, causing the clamping wheels on both sides to move towards each other under the action of spring rebound force to clamp and fix the end of the fire hose.

[0011] Secondly, when using the fire hose, the personnel remove the positioning bolt to unlock the position of the sliding rod. Sliding the sliding rods on both sides causes the sliding rods to move the clamping wheel away from the end of the fire hose, allowing the positioning bolt to be reinserted into the positioning hole corresponding to the sliding rod. This repositions the clamping wheel so that it does not limit the fire hose, allowing the fire hose to be pulled and unwound.

[0012] Thirdly, the combination of sliding rod, sliding column, sliding cylinder and spring can drive the clamping wheel to stably clamp the end of the fire hose, which can effectively prevent the fire hose from loosening inside the fire box when rewinding, and facilitate use.

[0013] Fourth, the elastic rubber sleeve in the middle of the clamping wheel allows for flexible contact between the clamping wheel and the fire hose, which can effectively prevent damage to the fire hose during the clamping process. Attached Figure Description
