The inlet of the control valve 5 is communicated with the connecting ring 16, so that the storage cavity 7 of the hand-held rod 1 is communicated with the inlet of the control valve 5 through the connecting ring 16.

[0026] A piston rod 8 is slidably installed in the storage cavity 7 of the hand-held rod 1. The end of the piston rod 8 is fixedly installed with a guide rod 9. A connecting sleeve 10 is threadedly installed at the tail of the hand-held rod 1. A pressing rod 11 is slidably installed in the connecting sleeve 10. The guide rod 9 is slidably inserted into the pressing rod 11. A return spring 12 is sleeved on the surface of the guide rod 9. The two ends of the return spring 12 respectively abut against the end of the piston rod 8 and the pressing rod 11. A locking bolt 13 is threadedly installed on the surface of the connecting sleeve 10.

[0027] Working principle: Remove the hand-held rod 1, pull out the pressing rod 11, the piston rod 8 slides in the storage cavity 7, so that a negative pressure is formed in the storage cavity 7, and the paint can be sucked into the storage cavity 7 through the negative pressure. Then assemble the hand-held rod 1 and the mounting frame 2 together. During use, press the pressing rod 11 and tighten the locking bolt 13 to fix the pressing rod 11. The return spring 12 is compressed and stores a certain amount of elastic potential energy. At this time, the control valve 5 is in a closed state, and the piston rod 8 is in a static equilibrium state. When the control valve 5 is opened, the elastic potential energy of the return spring 12 is released, driving the piston rod 8 to slide in the storage cavity 7, squeezing out the paint inside it. The paint is introduced into the support shell 4 through the feed pipe 6, so that the surface of the painting roller 3 can dip the paint and paint the wall.

[0028] In this embodiment, the painting device further includes an auxiliary roller 17. A threaded hole is provided at the end of the assembly sleeve 14, and a threaded rod is provided at the end of the auxiliary roller 17.

An external threaded groove is provided at the end of the connecting sleeve 10, and the tube body 19 is threadedly connected to the external threaded groove of the connecting sleeve 10. By providing the extension rods 18, according to the required length, the multiple extension rods 18 are butted against each other and then assembled with the tail of the hand-held rod 1, increasing the length of the device and expanding the working range. By pressing the telescopic rod 20, the reset spring 12 can also be worked on and energy stored. The operation is convenient and practical, meeting the usage requirements of different working environments.

[0031] For the wall painting device for interior decoration and fitment, by providing a pressing rod 11 at the tail of the hand-held rod 1 and pressing the pressing rod 11 against the ground, the reset spring 12 is compressed, and kinetic energy is stored by the reset spring 12. After the control valve 5 is opened, the reset spring 12 does work on the piston rod 8, squeezing the paint in the storage cavity 7 into the support shell 4.
