[0042] When the flow monitor 7 detects that the flow is too large (small), the telescopic push rod 103 pushes the speed to be reduced (increased), the two regulating wheels 304 are simultaneously driven to rotate by the servo motor 402 to make the width of the regulating cavity channel 3043 be narrowed (widened), so as to achieve the effect of reducing (increasing) the cross section through which the flow passes. In the whole process, the extrusion columns 303 will be stretched and contracted to different degrees along with the rotation of the regulating wheels 304, and always maintain the abutting state. Meanwhile, the rotation direction of the regulating wheels 304 can be defined along the flow direction of the grease, so that the regulation is smoother.
