Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

referring to fig. 1 to 4, an anti-slip wrench structure,

the anti-slip wrench structure includes:

the wrench comprises a wrench handle 1, a first tong head 2 and a second tong head 3;

the first tong head 2 and the second tong head 3 are fixedly connected to the working end of the wrench handle 1;

the opposite surfaces of the first binding clip 2 and the second binding clip 3 are parallel to each other;

the anti-skid wrench structure further comprises a movable clamp 4, an action rod 6 and a fulcrum 10;

the middle part of the movable clamp 4 is rotationally 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 long guide hole 5;

one end of the action rod 6 is fixedly connected with a guide rod 7 matched with the long guide hole 5, the other end of the action rod 6 is freely suspended, and the guide rod 7 can slide in the long guide hole 5;

the fulcrum 10 is fixedly connected to the outer side of the first binding clip 2, and the lower side surface of the action rod 6 is contacted with the upper end of the fulcrum 10.

When the wrench is used, one end of the action rod 6 is pressed to enable the guide rod 7 on the other end of the action rod 6 to push the movable pliers 4 to rotate at the upper end of the first plier head 2, so that the action surface of a bolt and the wrench is provided with one more movable pliers, and the wrench slippage prevention effect is achieved.

The distance from the fulcrum 10 to the end close to the elongated guide hole 5 of the action lever 6 is smaller than the distance from the fulcrum 10 to the free end. The lever principle is utilized to push the movable pliers (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 in the clockwise direction is more than 0 degree and less than 180 degrees. The inconvenience of operation caused by the overlong suspended end of the action rod 6 is avoided.

The fulcrum 10 is rotatably connected with the action rod 6 through a rotating shaft. The action lever 6 is fixed by two points so as not to rotate disorderly.

The working end of the action rod 6 is bent towards the movable clamp 4. Further avoiding the inconvenience of operation caused by the overlong suspended end of the action rod 6.

The action lever 6 further includes:

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 greater than the width of the long guide hole 5 at the tail part of the movable clamp 4, and the two ends of the guide rod 7 are respectively fixedly connected between the first mounting plate 11 and the second mounting plate 12. Which serves to prevent the guide rod 7 from slipping out of the elongated guide hole 5.

One side of the wrench handle 1 close to the action rod 6 is provided with a groove 8 with the width matched with that of the suspended end of the action rod 6. During the use, on the one hand, 6 unsettled one ends of action bars can imbed in recess 8, avoid outstanding spanner handle 1 to use uncomfortable, and on the other hand increases 6 turned angle of action bars for movable clamp 4 is inseparabler with the combination of bolt, further avoids the spanner slippage.

A layer of rubber 9 is fixedly connected to the position 5cm-10cm away from the suspended end of the action rod 6 on the action rod 6. Avoiding the action lever 6 being too stiff and increasing the operating comfort.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
