The solution is easy to operate, and adding paint at one time ensures long operation time, avoids the situation of frequent dipping of paint, and can be used in different operation scenarios. The storage capacity of the plastic liquid storage tank 2 is small, which reduces the burden on the operator without affecting the operation. The overall use is convenient, the structure is simple and easy to maintain.

[0023] In another embodiment, Figure 1 As shown, the grooves 13 are linearly and evenly distributed on the outer wall of the inner cylinder 12 , and the specifications and dimensions of the fixing bolts 14 are adapted to the specifications and dimensions of the grooves 13 .

[0024] The groove 13 is opened on the outer wall of the inner tube 12 and does not penetrate through it, so that the fixing bolt 14 is inserted into the groove 13 at one end of the outer tube 9 to fix the position of the inner tube 12, which is convenient for adjustment and fixation, and increases the function of adjusting the length of the outer tube 9 and the inner tube 12, which is convenient for auxiliary adjustment.

[0025] In another embodiment, Figures 1-4 As shown, one side of the sealing cone sleeve 21 is fixedly mounted on the outside of the hollow rotating rod 20, and the inside of the sealing cone sleeve 21 is movably sleeved on the outside of the connecting pipe 17. One side of the sealing cone ring 25 is fixedly mounted on one end of the connecting pipe 17, and the outside of the sealing cone ring 25 is movably sleeved on the inner wall of the hollow rotating rod 20.
