plate 402 to rise, the push plate 402 pushes the elastic plate 404 through the push rod 403, the elastic plate 404 pushes the piston 405 through the elasticity of the elastic plate 404, after the air storage tank 401 expands to a certain degree to push the push plate 402 to rise to a certain distance, the huge elasticity of the elastic plate 404 pushes the piston 405 to be separated from the clamping connection with the elastic strip 407, and meanwhile, the elastic strip 407 deforms and separates, at this time, when the huge resilience of the elastic plate 404 pushes the piston 405 upwards instantly, air is blocked by the one-way valve C of the air inlet slot 409 to enter the air storage slot 408 through the one-way air outlet valve 410, and then the fan 411 is blown to rotate, the fan 411 reciprocally stirs the fixed shifting block 414 through the metal shifting block 413 connected with the top spring 412, so as to generate high-frequency sound, which can be greatly different from low-frequency noise generated by the operation of a machine, so that a worker can immediately perform manual ice water spraying cooling and close the electric perforating machine 312 and the electric telescopic rod 1 when hearing the high-frequency sound, thereby greatly reducing the occurrence of over-high temperature and internal part damage caused by long-time work or internal fault of the electric perforating machine 312, push pedal 402 descends in step after the inside air cooling of air receiver 401 and passes through stay cord 406 pulling piston 405 and elastic strip 407 joint once more, the air that returns normal position piston 405 top gets into through air inlet duct 409, thereby can stir the stirring board 502 and make stirring board 502 stir slip ejector pad 503 and go up and down the slip at shower nozzle 307 inner wall when being sprayed cutting fluid simultaneously, it descends to promote filter screen sliding frame 505 through connecting rod 504 and carry out the slip of horizontal direction to slide ejector pad 503 simultaneously, thereby reciprocal drive filter screen 506 shakes under the bounce effect of little elastic plate 507, thereby also can shake the cutting fluid that will adhere to the surface solidification in filter screen 506 through vibrations and scatter when cutting fluid to the whereabouts is tight filterable, thereby promote the water flowing rate and the filtration efficiency of filter screen 506, the condition of reduction jam takes place.
