Electromagnetic pinch valve used in ultrasonic stone removing equipment

The utility model provides an electromagnetic pinch valve used in ultrasonic stone removing equipment. The electromagnetic pinch valve used in the ultrasonic stone removing equipment comprises a base and a telescopic assembly; a U-shaped groove is formed in the base; the telescopic assembly comprises an electromagnet, a push rod and a spring, the push rod is arranged in the U-shaped groove to compress a hose when the electromagnet is supplied power, and the push rod returns to be arranged on one side of the U-shaped groove and liquid contained in the hose flows smoothly when the electromagnet loses power. The push rod in the electromagnetic pinch valve is arranged on the base, a connecting rod of the push rod is arranged in the electromagnet of the push rod, and therefore the stability of the overall push rod is better in the movement process; the push rod moves in the determined direction of a first sliding groove, and therefore the movement direction is easy to control.
