An operating handle 13 is provided on the top of the base 11. The liquid supply assembly 2 includes a liquid tank 21 and a pump body 22. The liquid tank 21 is installed on the top of the base 11 and is used to hold repair liquid, selected according to actual conditions. The pump body 22 is installed on the side of the liquid tank 21. The input end of the pump body 22 extends to the bottom of the inner cavity of the liquid tank 21 through a pipe, and the output end of the pump body 22 is provided with a diversion pipe. The pump body 22 can inject the liquid in the liquid tank 21 into the diversion pipe. A first connecting hose 23 is provided at the top of the diversion pipe. The spraying assembly 3 includes a support base 31, a telescopic transmission rod 32, and a connecting seat 33. The connecting seat 33 is located on top of the support base 31, which is a hollow cuboid. The telescopic transmission rod 32 passes through the support base 31 and the base 11. A bearing is provided at the connection between the telescopic transmission rod 32 and the support base 31. The upper part of the telescopic transmission rod 32 is connected to the connecting seat 33. The connecting seat 33 is located on top of the support base 31, serving as a support and mounting structure. The bottom of the connecting seat 33 is connected to the top of the support base 31 via an electric telescopic rod (not shown in the figure), and the height of the connecting seat 33 can be adjusted via the electric telescopic rod. The bottom of the telescopic transmission rod 32 is connected to a drive shaft via a bevel gear set (not shown in the figure), which consists of two sets of meshing bevel gears. The inner cavity of the connecting seat 33 is provided with a U-shaped sealing plate 34. A vertical slot 6 is formed on the side of the sealing plate 34. A matching sliding block is slidably disposed within the vertical slot 6. The vertical slot 6 limits and guides the movement of the sliding block. A follower block 38 is fixedly connected to one end of the sliding block, and a nozzle assembly 35 is hinged to the other end of the follower block 38. The nozzle assembly 35 is connected to the output end of the pump body 22 via a first connecting hose 23. Preferably, there are two spraying assemblies 3. The pump body 22 is electrically connected to a power source.

[0026] The connecting seat 33 includes a top plate, a bottom plate, and a side plate. The two opposite ends of the side plate are connected to the top plate and the bottom plate, respectively. The side plate is perpendicular to the top surface of the base 11. The upper part of the telescopic transmission rod 32 moves through the bottom plate of the connecting seat 33, and the top of the telescopic transmission rod 32 moves through the connecting seat 33 and is fixed with a rotating shaft. The rotation of the telescopic transmission rod 32 causes the rotating shaft to rotate. The rotating shaft is rotatably located inside the bottom plate of the connecting seat 33. A rotating column is fixedly sleeved on the outer wall of the rotating shaft. A spiral groove (not shown in the figure) with closed ends is opened on the outer wall of the rotating column. The rotation of the rotating column causes the locking pin to move up and down through the spiral groove, thereby causing the follower block 38 to move up and down. The rotating column is located inside the sealing plate 34. The end of the sliding block away from the follower block 38 is embedded in the spiral groove through the locking pin. A guide rod 37 is installed between the top and bottom plates of the connecting seat 33. A follower block 38 is movably sleeved on the outer wall of the guide rod 37 to ensure stable up-and-down movement of the follower block 38. The guide rod 37 is vertically fixed inside the connecting seat 33 and located outside the sealing plate 34. An L-shaped connecting frame is provided at the bottom of the follower block 38, which serves as a support and installation structure. The connecting frame includes a horizontal plate and a vertical plate. One end of the horizontal plate and one end of the vertical plate are vertically connected. The bottom of the follower block 38 is connected to the top of the vertical plate. A lifting rod is movably inserted into the horizontal plate. The lifting rod can move up and down. A T-shaped slider is hinged to the top of the lifting rod. A T-shaped groove adapted to the T-shaped slider is opened at the bottom of the nozzle assembly 35. The T-shaped slider is installed in the T-shaped groove. The movement of the lifting rod can cause the nozzle assembly 35 to start swinging. A return spring 312 is sleeved on the outer wall of the lifting rod. One end of the return spring 312 is fixed to the top of the L-shaped connecting frame, and the other end is fixed to the top of the outer wall of the lifting rod. The bottom of the lifting rod is equipped with ball bearings to reduce contact wear with the cam 311.

[0027] At the bottom of the horizontal plate of the connecting frame, corresponding to the position of the lifting rod, a cam 311 is rotatably set with the lifting rod via two supports and a rotating shaft. The cam 311 is located between the two supports, and the rotating shaft moves through the upper part of the cam 311 and one support. The cam 311 is movably connected to the two supports via the rotating shaft. The bottom of the lifting rod slides against the outer wall of the top of the cam 311. The rotation of the cam 311 causes the lifting rod to move up and down reciprocally, thereby causing the nozzle assembly 35 to swing.

[0028] The follower block 38 is rotatably equipped with an auxiliary rod, which is rotatably connected to the follower block 38 by a bearing. The auxiliary rod and the rotating shaft are connected by a sprocket drive assembly 310, which consists of a sprocket and a chain. A follower gear 314 is sleeved on the outer wall of the auxiliary rod. A rack 39 is provided on the outer wall of the sealing plate 34 on the side away from the connecting seat 33, and it meshes with the follower gear 314. The follower gear 314 and the rack 39 are connected by meshing. When the follower block 38 moves up and down, the auxiliary rod rotates through the cooperation of the follower gear 314 and the rack 39, which in turn causes the cam 311 to rotate through the sprocket drive assembly 310.

[0029] The nozzle assembly 35 includes a nozzle body 351 hinged to the follower block 38. A flow cavity 352 is provided inside the nozzle body 351 for spraying liquid. The end of the flow cavity 352 away from the connecting seat 33 passes through the nozzle body 351. A rectangular cavity 354 with a rectangular cross-section is provided inside the nozzle body 351 away from the connecting seat 33 to facilitate gas flow. A connector 353 communicating with the rectangular cavity 354 is provided at the top of the nozzle body 351 for connecting the second connecting hose 26. Air outlets 355 communicating with the rectangular cavity 354 are provided at the top and bottom of the end of the flow cavity 352 away from the connecting seat 33. The air outlets 355 spray gas, forming wind at the opening of the flow cavity 352, which blows the sprayed liquid, allowing the liquid to be sprayed out more quickly, while avoiding the liquid being blown away by the wind and wasting liquid, thus improving the spraying quality.

[0030] A hollow block 27 is provided on the inner wall of the bottom of the liquid tank 21. An elastic telescopic rod 28 is vertically inserted into the top of the hollow block 27. A bearing is provided at the connection between the elastic telescopic rod 28 and the hollow block 27. The elastic telescopic rod 28 consists of a sleeve, a movable tube, and a spring. The lower part of the elastic telescopic rod 28 passes through the hollow block 27, the liquid tank 21, and the base 11. The bottom of the elastic telescopic rod 28 is connected to the outer wall of another drive shaft through a bevel gear set. The rotation of the drive shaft causes the elastic telescopic rod 28 to rotate through the bevel gear set. Multiple sets of agitator impellers 29 are provided at the bottom of the outer wall of the elastic telescopic rod 28, above the hollow block 27, and at the top of the outer wall of the elastic telescopic rod 28. When the elastic telescopic rod 28 rotates, the agitator impellers 29 agitate the liquid in the liquid tank 21, improving the quality of the liquid.

[0031] The top of the elastic telescopic rod 28 is equipped with a support plate, and the top of the inner cavity of the liquid tank 21 is equipped with a receiving plate 210. The bottom of the receiving plate 210 is equipped with a mounting plate corresponding to the support plate, and the support plate is connected to the mounting plate. The top of the support plate is equipped with an arc-shaped protrusion 211, and the bottom of the mounting plate is equipped with a contact post 212 that mates with the arc-shaped protrusion 211. The bottom of the contact post 212 is equipped with a ball bearing. The rotation of the elastic telescopic rod 28 causes the support plate to rotate, thereby causing the arc-shaped protrusion 211 to intermittently contact the contact post 212, causing the elastic telescopic rod 28 to expand and contract, thus improving the stirring quality of the liquid.

[0032] A drive shaft 25 is movably inserted into the hollow block 27. One end of the drive shaft 25 is connected to the elastic telescopic rod 28 through a bevel gear set. The bevel gear set is located inside the hollow block 27. The other end of the drive shaft 25 movably passes through the liquid tank 21 and is movably fitted with a support seat 24. The support seat 24 is located on the outside of the liquid tank 21 and is set on the top of the base 11.

[0033] The drive shaft 25 is fixedly fitted with an exhaust fan blade (not shown in the figure) on the outer wall of the receiving seat 24. An air inlet is provided on the side of the receiving seat 24 away from the liquid tank 21. A filter screen is provided at the air inlet. A second connecting hose 26 is provided on the top of the receiving seat 24. The second connecting hose 26 is connected to the connector 353. A solenoid valve is provided inside the second connecting hose 26. The drive shaft 25 drives the exhaust fan blade to rotate, so that gas is sprayed out from the air outlet 355.

[0034] When there are two spraying components 3, there are correspondingly two first connecting hoses 23 and two second connecting hoses 26. The first connecting hose 23 on the same side is connected to the nozzle assembly 35 on the same side, and the second connecting hose 26 on the same side is connected to the connector 353 on the same side. The liquid tank 21 is located above one drive shaft, and the spraying component 3 is located above the other drive shaft. All electrical components in this invention are connected to an external power source via wires.
