When the position of the heating ring is shifted during the crimping process, the edge of the heating ring will collide with the limit plate, and will also align the limiter. Pressure is applied to the position plate. Since the piston is fixed at one end of the limit plate, and the limit plate and the piston are both slidably connected to the vertical plate, the resistance of the limit plate by the heating ring will cause the piston to squeeze the gas inside the gas storage tank. In the interior of the air inlet, since the interior of the air passage is slidably connected with a positioning block that can engage with the third gear fixed outside the third pressing roller, when the gas in the air storage tank enters the interior of the air passage through the air pipe, the gas will The positioning block will be squeezed to approach the third gear.
