The movable ring 9 is fixedly connected, and the outer side of the movable ring 9 is provided with an external thread 10. The movable ring 9 is threadedly connected to the knob 11 through the external thread 10. The knob 11 is located on the adjusting cylinder 2. The knob 11 and the adjusting cylinder 2 can be rotatably connected through a bearing. The first movable inclined block 7 is provided with connecting plates 12 on both sides. One side of the connecting plate 12 is fixedly connected to the movable rod 13. One end of the movable rod 13 is connected to the circular plate 15 through the fixed seat 14 to limit the movement distance of the movable rod 13. The fixed seat 14 is fixedly connected to the adjusting cylinder 2. A spring 16 is sleeved on the movable rod 13.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, when it is necessary to reduce the ink flow, rotating knob 11 moves the moving ring 9 downwards. This downward movement causes the first moving inclined block 7 to move downwards as well. The first moving inclined block 7 contacts the inclined surface of the second moving inclined block 8, causing the second moving inclined block 8 to move towards the flexible tube 6. One end of the second moving inclined block 8 squeezes the flexible tube 6, thereby reducing its cross-sectional area, increasing ink flow resistance, and reducing the ink flow. When it is necessary to increase the ink flow, rotating knob 11 in the opposite direction moves the moving ring 9 upwards. Under the action of spring 16, this causes the second moving inclined block 8 to move in the opposite direction, thereby increasing the cross-sectional area of ​​the flexible tube 6, reducing ink flow resistance, and increasing the ink flow. This design allows users to flexibly adjust the ink flow as needed, greatly improving the user experience and creative effect of watercolor pens, and meeting diverse user needs.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting a first moving inclined block 7 and a second moving inclined block 8, and using a knob 11 to drive the moving ring 9 to move up and down, the pressure on both sides of the hose 6 can be precisely adjusted to achieve compression of the hose 6. This design allows users to flexibly adjust the ink output as needed, and by fitting a spring 16 on the moving rod 13 and connecting it to the fixed base 14 via a connecting plate 12, it is ensured that the first moving inclined block 7 can still operate smoothly under pressure changes. This innovative design greatly improves the user experience and creative effect of watercolor pens, meeting the diverse needs of users. In addition, by using a transparent material for the adjusting cylinder 2, users can directly observe the state of the internal hose 6, facilitating monitoring of the working status of the hose 6 and improving ease of use.
