A drain groove 11 is opened on the inner wall of the second drain seat 7. A drain grid 12 is provided on the inner wall of the drain groove 11. The pump 8 at the ends of the first drain seat 6 and the second drain seat 7 that are far apart from each other is started at the same time, so that the quenching liquid is drawn out at the filter frame 9 at the bottom end of the quenching fixture box 1, and then sprayed evenly from the drain grid 12 of the drain groove 11 to carry out the surface quenching liquid flow quenching operation of the workpiece inside the quenching fixture box 1.

[0025] Working Principle: During use, the operator first places the workpiece to be quenched into the quenching fixture 1. Then, simultaneously starting the pumps 8 at opposite ends of the first and second drain seats 6 and 7, the quenching liquid is drawn from the filter frame 9 at the bottom of the quenching fixture 1 and evenly sprayed from the drain grid 12 of the drain tank 11. This allows for surface quenching of the workpiece inside the quenching fixture 1. The first and second drain seats 6 and 7 can also work in conjunction with the spray grid 5 of the four corner distribution pipes 4 to spray quenching liquid at the four corners of the quenching fixture 1, ensuring full contact between the quenching liquid and the workpiece. Simultaneously, the filter element 14 can be inserted and installed inside the filter frame 9 via the sealing side seat 13. The filter screen 10 inside the filter frame 9 filters the waste inside the quenching liquid and recycles the quenching liquid. In daily use, the operator can place the workpiece in the center of the quenching fixture box 1, and then activate the shrinkage airbags 3 inside the shrinkage covers 2 on both sides of the quenching fixture box 1 to make them simultaneously connect with the center of the quenching fixture box 1, and connect with the heat insulation plate 15 at one end.
