Claims

[Scope of utility model registration request]

A tube welding device for sandwiching the middle part of a tube made of a heat-fusible material between a pair of electrodes and welding the middle part with the tube's cross section crushed, the tube welding device comprising: a substrate; a first electrode fixed to the upper surface of one end of the substrate; a guide implanted on the upper surface of the intermediate portion of the substrate at right angles to the substrate; and a sliding block loosely fitted to the guide;
provided between this sliding block and the substrate,
a spring that biases the sliding block in a direction away from the substrate; and a second electrode that is fixed to a portion of the lower surface of the extending piece that is fixed to the front surface of the sliding block and faces the first electrode. , a first swinging arm having one end pivoted to a fixed part near the end of the guide; one end pivoting to the sliding block and the other end of the first swinging arm; Connected to the other end so that it can swing freely,
a second swinging arm that constitutes a toggle mechanism together with the first swinging arm, and a tensioning arm that has one end pivoted at the connection between the second swinging arm and the first swinging arm. and,
and a solenoid pivotally supported on the other end of the substrate and pulling the tension arm along the substrate when energized.
