The rotation of the threaded rod 12 can drive the threaded slider 13 to move. The movement of the threaded slider 13 can drive the mounting plate 16 to move. The movement of the mounting plate 16 can drive the fixing frame 10 and the delivery pump 4 to move.

[0029] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0030] In use, when maintenance of the spray mechanism 1 is required, pulling the pulling block 28 causes the sliding plate 24 to move. The movement of the sliding plate 24 causes the toothed plate 27 to move, which in turn causes the drive gear 26 and the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 causes the two driven gears 19 to rotate, which in turn causes the toothed plate 20 to move. The movement of the toothed plate 20 causes one end to disengage from the snap-fit ​​groove 23, thereby releasing the fixation of the plug-in rod 22. Then, pulling the fixing bracket 10 separates the fixing bracket 10 from the mounting plate 16, and then separating the delivery pump 4 from the connecting hose 3, thus completing the disassembly of the delivery pump 4. This allows the staff to easily and quickly disassemble the delivery pump 4 when maintaining the spray mechanism 1, improving the convenience of maintenance. Furthermore, by reversing the above steps, the staff can easily and quickly install the delivery pump 4.
