| Zusammenfassung: | The utility model relates to a tension mechanism, in particular to a tension mechanism of an egg stripping needle pulling instrument. The tension mechanism is composed of a left tension output device, a right tension output device and pull ropes, wherein the left tension output device and the right tension output device are symmetrical to each other, the pull ropes are connected to the left tension output device and the right tension output device respectively, and the left tension output device and the right tension output device are each composed of a supporting plate, a driving shaft, a winch and a linkage gear which are arranged side by side. The tension mechanism can synchronously pull the pull rope and can apply consistent tension to the pull rope, so that the tension at the two ends of the glass tube can be synchronous and consistent in size, the consistent fracture length can be ensured, the same position can be heated all the time, the heating efficiency can be effectively improved, and the tension p |
