[0026] The effect achieved by the entire embodiment 1 is that, by setting the hexagonal probe rod 12, when the valve core body 9 is pressed into the interior of the valve housing body 7, it can be detected whether the valve core body 9 is pressed down to the specified position. During the downward pressing process of the valve core body 9, the hexagonal probe rod 12 will be pushed downward. When the copper sheet 16 and the copper contact 17 fit each other, the external indicator light 8 will light up. At this time, the valve core body 9 is pressed into the specified position inside the valve housing body 7, and the assembly can be completed.
[0027] Example 2, as Figure 1-4As shown, the two copper contacts 17 are located directly below the two copper sheets 16. The two copper contacts 17 are electrically connected to the indicator light 8. A spring 15 is fixed to the bottom of the movable plate 14 near the edge of the outer surface. The bottom of the spring 15 is fixed to the inner bottom surface of the adjustment cavity 13. The bottom of the hexagonal probe 12 slides through the bottom of the workbench 1. A side opening 5 is opened at the top of the workbench 1 near one side edge. A tightening screw 6 is provided on the inner wall of one side of the side opening 5. One end of the tightening screw 6 penetrates into the limit groove. 4, a pressing plate 11 is fixed to one end of the pressing screw 6, a valve housing body 7 is provided inside the limiting groove 4, one side of the pressing plate 11 is in contact with the outer surface of one side of the valve housing body 7, and the top of the hexagonal probe 12 extends to the inside of the valve housing body 7.

[0028] The effect achieved by the entire embodiment 2 is that the valve housing body 7 is placed inside the limiting groove 4, so that the top of the hexagonal probe rod 12 extends to the inside of the valve housing body 7, and then the valve housing body 7 is pressed and fixed inside the limiting groove 4 by the compression screw 6 driving the compression plate 11, and then the valve core body 9 is placed above the valve housing body 7, and the pressure column 10 is driven downward by the extension of the electric telescopic rod 3, so that it presses the valve core body 9 into the interior of the valve housing body 7.
