the middle part of the movable clamp 4 is rotatably connected to the upper end of the first clamp head 2 through a rotating shaft, the head part of the movable clamp 4 points to the second clamp head 3, and the tail part of the movable clamp 4 is provided with a strip guide hole 5;
one end of the action rod 6 is fixedly connected with a guide rod 7 matched with the strip guide hole 5, the other end of the action rod 6 is freely suspended, and the guide rod 7 can slide in the strip guide hole 5;
the fulcrum 10 is fixedly connected to the outer side of the first clamp head 2, and the lower side surface of the action rod 6 is in contact with the upper end of the fulcrum 10.
When the wrench is used, one end of the action rod 6 is pressed, the guide rod 7 at the other end of the action rod 6 pushes the movable clamp 4 to rotate at the upper end of the first clamp head 2, so that the action surface of the bolt and the wrench is one more movable clamp, and the wrench slipping prevention effect is achieved.
The distance from the fulcrum 10 to the end near the long guide hole 5 of the action bar 6 is smaller than the distance from the fulcrum 10 to the suspended end. The lever principle is utilized to push the movable clamp 4 to rotate, so that the labor is saved.
The included angle between the strip guide hole 5 and the head of the movable clamp 4 is larger than 0 DEG and smaller than 180 deg. The operation inconvenience caused by overlong suspending end of the action rod 6 is avoided.
The fulcrum 10 is rotatably connected with the action bar 6 through a rotating shaft. The action bars 6 are fixed by two points so as not to rotate in disorder.
The working end of the action bar 6 is bent towards the direction of the movable clamp 4. Further avoiding the inconvenient operation caused by overlong suspending end of the action rod 6.
The action bars 6 further comprise:
a first mounting plate 11 and a second mounting plate 12;
the lower ends of the first mounting plate 11 and the second mounting plate 12 are fixedly connected with the working end of the action rod 6, the distance between the first mounting plate 11 and the second mounting plate 12 is larger than the width of the long guide hole 5 at the tail part of the movable clamp 4, and two ends of the guide rod 7 are respectively and fixedly connected between the first mounting plate 11 and the second mounting plate 12. Acting to prevent the guide bar 7 from slipping out of the elongated guide hole 5.
