furthermore, the surfaces of the third gear 222 are uniformly and fixedly connected with teeth, the two groups of teeth are internally provided with the contact block 224, when the third gear 222 rotates under stress, the third gear 222 drives the teeth to continuously contact with the contact block 224, and after the contact block 224 is stressed, vibration can be quickly transmitted;

further, the fixing mechanism 230 includes a fixing member 231, one end of the fixing member 231 is connected to an inner wall of one end of the second moving groove 225 through a hinge shaft, one side of the fixing member 231 passes through the second moving groove 225 and extends into the second fixing support plate 210, one end of the shaft rod 213 is fixedly connected to a fixing plate 234, the surface of the fixing plate 234 is uniformly provided with fixing grooves 235, one side of the fixing member 231 is connected to the fixing member 231 through a hinge shaft, one side of the pulling block 232 is connected to a screwing member 233 through an embedded bearing, and one side of the screwing member 233 passes through the second fixing support plate 210 and extends to the outer side of the second fixing support plate 210, after the pouring is completed, an operator can press the pedal 215 downwards with force until the pedal 215 is stressed, and when the pedal is inclined downwards, the operator can continuously screw the screwing member 233 into the second moving groove 225, so as not to make the fixing member 231 quickly rotate and move out of the inside of the second moving groove 225 under force, until the fixing piece 231 rotates and moves to the inside of the fixing groove 235, the fixing disc 234 and the shaft rod 213 are quickly fixed, and the pedal 215 can be in a fixed state, so that an operator can conveniently pull the filling hose 110 back and forth, and the pedal 215 quickly rubs concrete surfaces after pouring, so that the concrete surfaces are quickly leveled.

The working principle is as follows: when a user uses the device to fill concrete, an operator can firstly continuously twist the twisting handle 119 to force the twisting handle 119, one end of the twisting handle drives the bevel gear to continuously mesh with the bevel gear sleeved on the surface of the linkage rod 116 in the communicating groove 114, the linkage rod 116 rapidly rotates in the communicating groove 114, and when the linkage rod 116 rotates, the bevel gear sleeved on two ends of the linkage rod can continuously mesh with the bevel gear sleeved on one end of the surface of the reverse threaded rod 115, so that the reverse threaded rod 115 is rapidly forced to rotate in the first moving groove 113, and when the reverse threaded rod 115 rotates, the reverse threaded rod 115 is mutually matched with the thread structure arranged on the thread sleeve 117, the thread sleeve 117 can rapidly slide close to each other on the surface of the reverse threaded rod 115, and when the thread sleeve 117 slides continuously, the surface continuously pulls two sides of one end of the folding support frame 112 through the hinging shaft, the folding support frame 112 is stressed to rapidly extend downwards on the surface of the filling hose 110, the moving sleeve 118 is pushed, the moving sleeve 118 can rapidly slide on the surface of the filling hose 110, the surface of the filling hose 110 is continuously wiped until the surface is in a vertical state, and then a user can rapidly hold the holding handle 120 with a hand, so that the filling hose 110 can be conveniently mastered;

then, when the user uses the device to pour concrete to the ground, until the concrete surface submerges the spring vibrating piece 223, the operator can insert the feet into the foot-restraining piece 216 and continuously step on the pedal 215, so that the pedal 215 drives the sector gear 214 to make a rotating motion in the second fixing support plate 210, the surface of one side of the sector gear 214 is continuously engaged with the surface of the turbine rod 212 while moving, the turbine rod 212 is stressed to quickly rotate in the second fixing support plate 210, and when the turbine rod 212 rotates, the turbine rod 212 drives the first gear 217 to rotate in the ring plate 211, when the first gear 217 rotates, the rotating piece 218 is quickly stressed, so that the rotating piece 218 continuously rotates in the ring plate 211, when the rotating piece 218 rotates, the inner portion of the rotating piece 218 can be quickly engaged with the second gear 221, the second gear 221 is stressed to rapidly drive the rotating rod 220 and the third gear 222 to rotate in the second fixing support plate 210, when the third gear 222 rotates, the third gear 222 continuously abuts against the abutting block 224, and after the abutting block 224 is contacted, the spring vibrating piece 223 is stressed to rapidly vibrate in the concrete, so that air bubbles doped in the concrete during pouring are removed by vibration;

after pouring is completed, an operator can forcibly step the pedal 215 downwards until the pedal 215 is stressed and is inclined downwards, the operator can continuously screw the screwing piece 233 into the second moving groove 225, after the screwing piece 233 is stressed, the surface of the screwing piece 233 is matched with a thread structure arranged on the inner wall of the second moving groove 225, the screwing piece 233 can quickly displace towards the inner wall of the second moving groove 225, the screwing piece 233 continuously moves and simultaneously continuously pushes the pull block 232 and the fixing piece 231, so that the fixing piece 231 is stressed to quickly rotate and move out of the second moving groove 225 until the fixing piece 231 rotates and moves into the fixing groove 235, the fixing disc 234 and the shaft lever 213 are quickly fixed, the pedal 215 can be in a fixed state, and then the operator can continuously pull the filling hose 110 back and forth, so that the pedal 215 quickly scratches the concrete surface after pouring, and quickly screeding the concrete surface.
