By moving the first handle 14 and the second handle 16 to both sides at the same time, the first rotating ring 12 and the second rotating ring 13 are rotated in opposite directions on the fixed column 1, thereby driving the first connecting block 14 and the second connecting block 15 to rotate. The connecting block 15 and the second connecting block 17 move to open the first clamp head 2 and the second clamp head 3. The first handle 14 and the second handle 16 are movably connected with an arc rod 18. The outer surface of the arc rod 18 is sleeved with a spring 19. The two ends of the spring 19 are respectively fixedly connected to the first handle 14 and the second handle 16. A slide groove 20 is provided in the arc rod 18. Two symmetrical sliders 21 are slidably connected in the slide groove 20. The two sliders 21 are fixedly connected to the side away from each other with an arc slide rod 22. The end of the arc slide rod 22 away from the slider 21 is fixedly connected to a limit block 23. The two limit blocks 23 are respectively fixedly connected to the first handle 14 and the second handle 16. The two sliders 21 slide in the arc rod 18 with the corresponding arc slide rods 22. When clamping When the object is between the first pliers 2 and the second pliers 3, the force of the first handle 14 and the second handle 16 moving to both sides is stopped, and the rebound force of the spring 19 assists the hand to initially clamp and fix the clamped object to prevent the object from slipping. The first pliers 2 and the second pliers 3 are provided with a plurality of evenly distributed protrusions 31 on the opposite side, and the plurality of protrusions 31 on the first pliers 2 and the plurality of protrusions 31 on the second pliers 3 are used to further fix the clamped object.
