side of the control plate 13, then the control plate 13 is loosened, the reset spring 17 pushes the reset block 16 to rotate and reset, then the reset block 16 drives the reset hole 14 and the reset slot 15 to rotate and reset to the position not corresponding to the clamping plate 20 and the support rod 21 through the control plate 13, then the support rod 21 and the clamping plate 20 cooperate to support the positioning sleeve 19 to one side of the control plate 13, cooperate with the sliding block 40 and the sliding slot 41 to limit the positioning sleeve 19, so that the positioning sleeve 19 cannot move, then the positioning sleeve 19 limits the outer end of the locking rod 42, so that the locking rod 42 cannot move, then the locking rod 42 and the locking slot 43 cooperate to lock the speed adjusting sleeve 11 to the outside of the fixed tube 5, prevent the speed adjusting sleeve 11 from rotating, so as to ensure the structural stability after the flow rate is adjusted, and further ensure the stable use of the equipment.

[0045] In all the above-mentioned solutions, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut cooperation connection, bolt or screw connection or other known connection mode, which will not be described one by one, and the welding is preferred for the fixed connection in the above-mentioned solutions. Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
