To achieve the above object, the utility model provides following technical scheme：One kind can adjust gap according to steel plate thickness
Lifting tongs, including suspension ring, self-locking spring and adjusting nut, the suspension ring are arranged on the upper left of lifting tongs body,
The lifting tongs body is internally provided with weight sensor, and middle position is set on the right side of the preceding surface of lifting tongs body
Fixing nut is equipped with, the adjusting nut is arranged on the preceding lower face of lifting tongs body, the right side of the lifting tongs body
Side middle position is provided with fixed installation plate, is provided with self-locking suspension ring on the right side of the fixed installation plate, and plate is fixedly mounted
Lower right be provided with connection chain, the self-locking spring is arranged on the lower section that plate is fixedly mounted close to the right side of connection chain
Side, biting teeth is provided with the left of the adjusting nut, pad is provided with the left of the biting teeth.
Preferably, the adjusting nut is provided with two altogether, and two adjusting nuts are installed in lifting tongs body
Preceding lower face.
Preferably, the self-locking spring is fixedly connected with plate is fixedly mounted by nut.
Preferably, the fixed installation plate is fixedly connected with self-locking suspension ring by being connected chain.
Preferably, the biting teeth is fixedly connected with lifting tongs body by adjusting nut.
Compared with prior art, the beneficial effects of the utility model are：This can adjust the lifting in gap according to steel plate thickness
Tongs is scientific and reasonable for structure, safe and convenient to use, and an adjusting nut is provided with lifting tongs body, passes through adjusting nut
The gap between biting teeth and pad is adjusted, so that lifting tongs body can lift by crane different steel plates, reduces the office of tongs
It is sex-limited；A weight sensor is provided with tongs, is issued by reminding when overweight, avoids the hanging object for lifting by crane load from occurring unexpected
The problem of accident.
