Internal ignition-free pneumatic repeater and single-channel push-pull rod on automobile pneumatic machine

Abstract

The invention relates to the field of a meson repeater for a welding gun, and in particular to a meson repeater for preventing internal ignition on an automobile meson machine and a single-channel push-pull rod. The invention comprises a meson providing part and a push-out system, wherein the push-out system comprises a shell arranged transversely, and the end of the push-pull rod (39) comprises a copper push rod (13). After the vertical part of the meson top sheet (11) is covered with an insulating convex sleeve (12), it passes through the hole of the push-pull rod (39), and then is fixed on the push-pull rod (39) through an insulating flat pad (14) and a retaining ring. The insulating convex sleeve (12) can move in the middle hole of the meson pressing sheet (22), and the copper push rod (13) can move left and right with the push-pull rod without contacting the meson pressing sheet (22). After the meson top sheet is pushed out, the copper push rod (13) moves to the end and contacts the copper head (18), and then is connected to the push-pull rod (39) and forms a conductive path with the meson sheet pushed out at the end.
