In this embodiment, the bending radius of the first hook head 6 and the second hook head 7 is the same as the radius of the broken pin shaft. Because the radius of the chain pin shaft used in the production field is many, the first hook head 6 and the second hook head 7 can be replaced according to the radius of the chain pin shaft.
Specifically, first gib head 6 and second gib head 7 are made with the forging, not only have certain intensity but also certain toughness, make the security performance of first gib head 6 and second gib head 7 improve, and work is more reliable.
The utility model is provided with a first threaded sleeve 1, a second threaded sleeve 2, a square head 3, a first jaw screw rod 4, a second jaw screw rod 5, a first hook head 6 and a second hook head 7; the first threaded sleeve 1 and the second threaded sleeve 2 are symmetrically arranged on two sides of the square head 3; one end of the first jaw screw 4 is screwed with the first thread sleeve 1, and the other end of the first jaw screw 4 is connected with the first hook head 6 through a first pin shaft 8; one end of the second jaw screw 5 is screwed with the second threaded sleeve 2, and the other end of the second jaw screw 5 is connected with the second hook head 7 through a second pin shaft 9. When the square head 3 is rotated by a wrench, the first jaw screw 4 and the second jaw screw 5 can move oppositely or in opposite directions at the same time, when the first jaw screw and the second jaw screw move relatively, two ends of a broken chain can be gradually close to each other, and the broken chain can be connected when the relative movement is enough. The utility model discloses can guarantee that the whole length of instrument is enough short, can not lead to the screw thread section of first jaw screw rod 4 and second jaw screw rod 5 dieback again, can adapt to the broken chain connection of more not equidimension pitches. The interference fit can rotate according to the stress direction, and not only can be connected with a broken chain on a plane, but also can be connected with a broken chain at a certain angle. Meanwhile, the free rotation of the two connecting pieces can be ensured, and the concentricity of the connecting pieces can be ensured. The hook head part is connected with the screw rod part through the pin shaft, can rotate by an angle, can be connected with a broken chain on a plane and can also be connected with a broken chain at a certain angle, namely, the broken chain on the plane and the broken chain at a certain angle can be connected through a tool. Meanwhile, the square head 3 is used for processing four planes, so that the chain breakage at two ends can be conveniently caused to approach constantly. Because the radius of the chain pin shaft used in the production field is many, the first hook head 6 and the second hook head 7 can be replaced according to the radius of the chain pin shaft.
