The horizontal portion 211 acts as a lever to save more effort for the operator in turning. At this time, the movement of the rack 52 is limited, so the gear 51 cannot rotate, and the rotating shaft 6 drives the ratchet wheel 131 to rotate clockwise until the ratchet of the ratchet wheel 131 collides with the limit strip 141. At this time, the ratchet teeth of ratchet wheel 131 push stopper 141 in a direction away from rotation shaft 6, compressing compression spring 16, flexible cord 17 is bent, and stopper 141 is rotated in a direction away from ratchet wheel 131 until the ratchet teeth of ratchet wheel 131 pass stopper 141. Thereafter, the ratchet wheel 131 continues to rotate, and continues to compress the coil spring 11. By increasing the number of turns of the rotating crank 21, the elastic force of the coil spring 11 is increased, so that the push plate 27 can push the water in the flushing pipe 22 more easily, the size of the water flow at the flushing port 7 is increased, and the water flow is adjusted.

The implementation principle of the uniform control device of the flusher in the embodiment of the application is as follows: when the flusher works, an operator installs the flusher on the support 1 through the fixing piece 19, then the flushing port 7 extends into water, the push plate 27 is pulled, and the flushing pipe 22 absorbs water through the flushing port 7 until the first limiting block 9 is abutted to the second limiting block 10. Then, the operator rotates the rotation shaft 6 by the crank 21, adjusts the elastic force of the coil spring 11, and then removes the crank 21 from the rotation shaft 6. At this time, the elasticity of the coil spring 11 is restored and the push plate 27 is pushed to move toward the rinsing port 7, and the water in the rinsing tube 22 enters the oral cavity of the patient through the rinsing port 7. In operation, the circular motion of the gear 51 indirectly drives the linear motion of the piston push rod 25, and the elastic force of the coil spring 11 can be balanced with the resistance of the water in the flushing pipe 22, so that the water leaves the flushing port 7 at a uniform speed, thereby reducing the possibility of influencing the treatment effect when the flow rate of the water flow at the water outlet is changed.
