[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a convenient adjustment device for a spray bar of a sprayer, including a pull-out spray bar and an adjustment assembly installed on the pull-out spray bar. The pull-out spray bar includes a hollow rod 1, a hollow rod 2, a connector 3, and a nozzle 4. The tail of the hollow rod 1 is connected to the connector 3, and the end of the hollow rod 2 is connected to the nozzle 4. The hollow rod 2 is fitted into the end of the hollow rod 1. The adjustment assembly includes a handle sleeve 5, a traction plate 6, a floating side plate 7, a drive wheel 8, and a limiter 9. The glove tube 5 is fixed to the hollow rod 1 and has an installation port 10 on its surface. The inner cavity of the glove tube 5 has a guide cavity 11. The traction plate 6 is located in the guide cavity 11 and its outer end is connected to the end of the hollow rod 2. The floating side plates 7 are divided into two groups and are symmetrically installed on both sides of the installation port 10. The drive wheel 8 is built into the installation port 10 and its two ends are rotatably connected to the floating side plates 7 on both sides. The drive wheel 8 is used in conjunction with the traction plate 6. The limiter 9 is installed on one side of the installation port 10 and is used in conjunction with the drive wheel 8.

[0020] Further improvements, such as Figure 1 As shown, both hollow rod 1 and hollow rod 2 have flow guiding channels 12 machined inside. Hollow rod 2 is movably fitted onto hollow rod 1 for flow guiding.

[0021] Further improvements, such as Figure 1 As shown, the traction plate 6 has a long, arc-shaped plate structure and several sets of protruding teeth 13 are machined on its surface. The traction plate 6 is used to adjust the position of the hollow rod 2.

[0022] Further improvements, such as Figure 3 As shown, the floating side plate 7 includes a laminated plate 14 and a mounting plate 15 fixed above the laminated plate 14. The laminated plate 14 is made of elastic metal material and its surface is processed into a laminated structure. The mounting plate 15 is rotatably connected to the drive wheel 8. This design facilitates the up and down movement of the drive wheel 8.

[0023] Further improvements, such as Figure 3As shown, the drive wheel 8 includes a wheel body 16 and several sets of teeth 17 machined and formed on the edge of the wheel body 16. The teeth 17 mesh with the protruding teeth 13. The rotation of the drive wheel 8 acts on the traction plate 6, causing the traction plate 6 to move laterally, thereby achieving the purpose of adjusting the position of the hollow rod 2.

[0024] Specifically, the limiter 9 includes an L-shaped support frame 18 fixed to the handle sleeve 5 by bolts and a limiting block 19 fixed to the end of the L-shaped support frame 18. The width of the limiting block 19 is equal to the distance between two adjacent sets of teeth 17. The limiting block 19 is used to engage with the teeth 17 of the drive wheel 8 to limit the drive wheel 8, thereby achieving the purpose of limiting the traction plate 6 and the pull-out spray bar.

[0025] In use: Connector 3 is connected to the sprayer via a pipe. The sprayed medicine is guided along connector 3, hollow rod 1, and hollow rod 2 and sprayed out through nozzle 4. The operator holds the handle and sleeve 5 to operate the spray bar. When the length of the pull-out spray bar needs to be adjusted, the operator presses down on the drive wheel 8 with their thumb. During the pressing process, the stacked plate 14 is compressed, the drive wheel 8 moves down and contacts the traction plate 6. At this time, the limiter 9 disengages from the drive wheel 8. The operator can then move the drive wheel 8 with their thumb to drive the traction plate 6 to move laterally, thereby pulling the hollow rod 2 to move laterally, achieving the purpose of adjusting the extension and retraction of the pull-out spray bar. After the adjustment is completed, the operator releases the pressure on the drive wheel 8, the drive wheel 8 resets, and the limiter 19 engages with the teeth 17 of the drive wheel 8 to achieve the purpose of limiting the position. This operation method is simple and convenient and does not affect the normal use of the spray bar.
