plate 503 deforms, when the lifting plate 504 rises, the dial rod 505 is pushed, the dial rod 505 is limited by the small hinged block 507, so that the water pushing plate 506 is driven by the push of the dial rod 505 to push the cutting fluid in the rotating dial plate 306, so that the cutting fluid in the rotating dial plate 306 is extruded, and the water pushing plate 506 can synchronously push the cutting fluid in the interior, and then the residues deposited in a short time and on the top of the rotary stirring plate 306 are pushed by the water pushing plate 506 to be mixed into the cutting fluid, and then the residues are extruded out along with the rotation of the rotary stirring plate 306, so that the short-term deposition is prevented, the uniform mixing efficiency of the cutting fluid is improved, and the due lubricating effect can be exerted to the maximum.
