[0028] The inner side of the outer sleeve support tube 1 is sleeved with a protective isolation sleeve 201, and the inner side of the protective isolation sleeve 201 is bonded with a waterproof fixing tube 202. The side ends of the outer sleeve support tube 1 are fixed with anti-slip support sleeves 203. A length fixing sleeve 204 is fixed at the position of the anti-slip support sleeve 203 at one end of the outer sleeve support tube 1. A sleeve fixing frame 205 is fixed at the position of the anti-slip support sleeve 203 at the other end of the outer sleeve support tube 1. The sleeve fixing frame 205 and the inner side of the length fixing sleeve 204 are fixed with a sleeve fixing frame 205. One end is fitted with the side end of the waterproof fixing tube 202 to achieve a steady snap connection and ensure the tightness of the connection. One end of the long and short fixing sleeve 204 and the sleeve fixing frame 205 are welded with a raised snap head 206. The water inlet pressure sealing bag 208 is sleeved on the inner end of the raised snap head 206, so that it can effectively cooperate when the snap seal is engaged to improve the sealing effect. The inner sides of the long and short fixing sleeve 204 and the sleeve fixing frame 205 are fixed with a porous support ring 207. The cam 208 is connected to the support frame 207 at one end, and the side ends of the two water inlet pressing bags 208 are respectively bonded to the sleeve fixing frame 205 and the inner end of the long and short fixing sleeve 204 to achieve steady water inlet extrusion and improve the stability of extrusion. A sliding fixing groove 209 is provided on the inner side of the sleeve fixing frame 205. A movable screw 210 is connected to the position of the sliding fixing groove 209 at one end of the sleeve fixing frame 205 through a screw seat. The movable screw 210 is rotated and placed on the inner side of the sliding fixing groove 209 to achieve steady rotation and drive. The side end of the movable screw 210 is connected to the isolation support plate 211 through the screw seat. The guide support column 212 is symmetrically welded on the inner side of the sliding fixing groove 209. The isolation support plate 211 is slidably installed on the inner side of the sliding fixing groove 209. The guide support column 212 slides and fits with the isolation support plate 211, so that the isolation support plate 211 can be steadily supported and restricted during the movement, thereby improving the accuracy of the movement and positioning.

[0029] A sliding assembly 3 is provided at the side end of the outer sleeve support tube 1. The sliding assembly 3 includes a clamping support groove 301, a positioning spring 302, a clamping movable plate 303, a semicircular closing cover 304 and a universal ball 305;

[0030] Several engaging support grooves 301 are equidistantly provided at the outer end of the outer sleeve support tube 1, and several positioning springs 302 are equidistantly installed at one end of the engaging support groove 301. One end of the several positioning springs 302 is welded with an engaging movable plate 303, and the middle part of one end of the engaging movable plate 303 is welded with a semicircular closing cover 304. The engaging movable plate 303 is slidably fitted with the engaging support groove 301, and the semicircular closing cover 304 is placed on the inner side of the engaging support groove 301 to achieve steady movement and replacement, and steady operation of lifting support and fixation. A universal ball 305 is rotatably connected to the inner side of the semicircular closing cover 304.

[0031] When the fire hose is in use, the firefighter unfolds the fire hose and puts the raised engaging head 206 at the position of the long and short fixing sleeve 204 onto the fire hydrant. During the process of pulling the fire hose, the side end of the fire hose contacts the ground. At this time, the positioning spring 302 pushes the engaging moving plate 303 to move along the engaging support groove 301. When the engaging moving plate 303 is pressed, the positioning spring 302 is squeezed, and the engaging moving plate 303 is completely embedded in the inner side of the engaging support groove 301. At this time, the universal ball 305 does not completely enter the inner side of the engaging support groove 301. During the process of the fire hose being pulled by the firefighter, the universal ball 305 is used to move along the semicircular closing cover 304 to convert the sliding friction into rolling friction, thereby reducing the force consumption of the fire hose during the pulling process, improving the convenience of pulling, and facilitating the operation of the firefighter.

[0032] When the water hose is in use, the nozzle is fixed and engaged by using the protruding engaging head 206 located at the position of the sleeve fixing frame 205. After the engagement is completed, the water valve of the fire hydrant is opened, and water flows into the nozzle position along the long and short fixing sleeves 204, the waterproof fixing pipe 202 and the sleeve fixing frame 205. The movable screw 210 drives the isolation support plate 211 to move from the waterproof fixing pipe 202 to the inner side of the sliding fixing groove 209 along the sliding fixing groove 209 and the guide support column 212, and the sleeve fixing frame 205 is opened. During the water inlet process, the water flows along the porous support ring 20 7 Enters the inner side of the water inlet pressing bag 208, and when water is injected into the inner side of the water inlet pressing bag 208 by using high pressure, the water inlet pressing bag 208 is squeezed into the gap between the protruding snap-fitting head 206 and the fire hydrant and the protruding snap-fitting head 206 and the nozzle, and the gap is filled to achieve a tight snap fit to ensure a steady water supply. In addition, the movable screw 210 is used to drive the isolation support plate 211 to move and control the water discharge of the fire hose, so that different nozzles can be switched according to the needs of fire extinguishing during the fire extinguishing process, which is convenient for firefighters to switch fire-fighting equipment in time and improve the efficiency of fire extinguishing.
