At this time, the clamping block 205 is located above the valve core. Then the electric push rod 104 is started to drive the clamping block to move downward to a suitable position, and then the dual-axis drive motor 207 is started to make the two fixed blocks 202 slide and shrink along the fixed rod 201 to clamp the valve core, wherein the damping spring shock absorber 203 is used to slow down the shrinkage speed of the clamping block 205 to avoid damage, and then the valve core is transferred by the transverse movement component 106. Similarly, the position of the moving component 101, that is, the valve core seat 103, is adjusted to clamp the valve core in turn, and then the receiving plate 102 can be replaced to start clamping the next valve core. When the clamping block 205 needs to be replaced, the limit rod 3 is pulled upward. At this time, the compression spring 302 and the telescopic rod 301 shrink, so that the limit rod is separated from the limit hole 206, and the clamping block 205 is separated from the fixed block 202 and replaced with a new one;

The valve core is then transferred using the lateral moving component 106. Similarly, under the condition that the first screw nut and the receiving plate frame 102 are fixedly connected, the position of the moving component 101, i.e., the valve core seat 103, is adjusted to clamp the valve core in turn. Then, the receiving plate frame 102 can be replaced to start clamping the next valve core. When the clamping block 205 needs to be replaced, the limit rod 3 is pulled upward. At this time, the compression spring 302 and the telescopic rod 301 are contracted, so that the limit rod is disengaged from the limit hole 206. The clamping block 205 is separated from the fixed block 202 and then replaced with a new one.
