The adjustable overtravel high current relay as claimed in claim 6, wherein: a second step with a downward step surface is arranged at the position, corresponding to the hook head, of the bottom of the second clamping hole; the upper portion of the second hook component is provided with a third step which is used for preventing overpressure and is provided with a downward step, when the second hook component is matched with the second clamping hole, the hook head of the second hook component is hooked at the second step of the second clamping hole, and the third step of the second hook component is abutted against the side of the upper hole edge of the second clamping hole, so that the integral component is limited in the vertical direction at the position corresponding to the second clamping hole.
8. The adjustable overtravel high current relay as claimed in claim 7, wherein: the second hook component is in transition fit with two opposite hole walls of the second clamping hole along the horizontal direction perpendicular to the axis of the iron core mounting hole, so that the integral component is limited at the position corresponding to the second clamping hole along the horizontal direction perpendicular to the axis of the iron core mounting hole; one of two opposite hole walls of the second clamping hole in the horizontal direction perpendicular to the axis of the iron core mounting hole is also set to be a wavy wall surface, so that after the first gap and the second gap are used for adjusting the over travel of the contact, the second hook member and the base are fixed together through hot melting treatment between the wavy wall surface of the second clamping hole and the second hook member, the integral component is limited at the position corresponding to the second clamping hole in the axial direction of the iron core mounting hole and in the horizontal direction perpendicular to the axis of the iron core mounting hole, and fine adjustment of the integral component in the position corresponding to the second clamping hole in the horizontal direction perpendicular to the axis of the iron core mounting hole is realized through the wavy wall surface.
9. The adjustable overtravel high current relay as claimed in claim 6, wherein: further, the iron core further comprises a yoke, the yoke is provided with a mounting foot, the mounting foot of the yoke is matched with the second hook component in the second clamping hole, and the mounting foot of the yoke is closer to the position right below the axis of the iron core mounting hole relative to the second hook component; one of two opposite hole walls of the second clamping hole along a horizontal direction perpendicular to the axis of the iron core mounting hole is farther away from the axis of the iron core mounting hole relative to the other hole wall and is just below the axis of the iron core mounting hole.
