[0015] The beneficial effects of the present invention are:

[0016] 1. The pull-tab device of the double-head zipper is designed to separate the two clamping claws due to the compression of the return spring during the pulling process. When the clamping box moves, when the push-link contacts the front stop block, the internal push plate moves backward, and the two clamping claws are pulled together by the pull rope to clamp the zipper. The contact of the push plate turns on the contact switch, energizing the electromagnet, so that the two clamping claws can clamp stably.

[0017] 2. The pull-tab device of the double-head zipper is configured to move the push plate so that the protruding top block protrudes from the clip box. When the zipper is pulled out to a specified length, the tail section of the clip box contacts the rear stop block, resetting the protruding top block, de-energizing the contact switch, separating the two clamping claws, and releasing the zipper. The contact of the rear contact plate squeezes the first air cushion inside, compressing the internal gas to the pneumatic push rod. The extension of the pneumatic push rod pushes out the slicing blade, cutting the zipper, so that the pull-tab device pulls the zipper out to a certain length and cuts it off.

[0018] 3. The pull-tab device of the double-head zipper is arranged in the process of clamping the zipper. Due to the conductivity of the electromagnet, the attraction of the metal slide plate on the top decreases, which generates pressure on the second air cushion, compressing the gas into the inside of the clamping claw air box, and compressing and expanding the rubber pad at the bottom. The rubber pad can make the clamping claw have a better clamping effect on the zipper. BRIEF DESCRIPTION OF THE DRAWINGS
