Working principle: When the steel bars need to be hoisted, first adjust the positions of the two first connecting blocks 23 and the second connecting blocks 25 according to the length of the steel bars. When the length of the steel bars to be hoisted is relatively short, the first connecting block 23 and the second connecting block 25 are relatively close. When the length of the steel bar to be hoisted is relatively long, the first connecting block 23 and the second connecting block 25 are far away from each other. According to different steel bar lengths, the first connecting block 23 and The spacing of the second connection block 25 is different to prevent that when hoisting the steel bar, single-point hoisting of the steel bar causes the steel bar to be unstable during hoisting, and when the output shaft of the motor 21 drives the screw mandrel 26 to rotate, the screw mandrel 26 is a two-way screw mandrel 26. When the screw mandrel 26 rotates clockwise, the first connecting block 23 and the second connecting block 25 are close to each other; The first connecting block 23 and the second connecting block 25 slide on the inside of the chute 22, so that the sliding of the first connecting block 23 and the second connecting block 25 is more stable, so that the first connecting block 23 and the second connecting block 25 are connected according to the reinforcement. The distance between the two clamping components 3 can be adjusted accurately and quickly, thereby improving the practicability and flexibility of the lifting and clamping equipment, and at the same time improving the working efficiency of the lifting and clamping equipment.
