Detailed Description

As shown in fig. 1-3, the present invention includes a flat tongs body 1, a fixed tongs mouth 3, a movable tongs mouth 2, a moving device and a tool 4, wherein the side of the flat tongs body 1 where the movable tongs mouth 2 is located is defined as the front side, and the side where the fixed tongs mouth 3 is located is defined as the rear side.

The fixed jaw 3 is fixedly arranged at the rear end of the flat-nose pliers body 1, the movable jaw 2 is positioned in front of the fixed jaw 3, a tooling part 4 is arranged between the movable jaw 2 and the fixed jaw 3, the tooling part is in an inverted convex shape, a sliding groove 10 is arranged on the top surface of the flat-nose pliers body 1, the convex part of the tooling part 4 is inserted into the sliding groove 10 to form clearance fit with the sliding groove 10, and the tolerance is 0.01-0.02 mm. The distance between the top surfaces of the two side vertical surfaces of the sliding chute 10 is a fixed value and is formed by grinding.

A moving device for pushing the sliding jaw 2 to move is arranged in front of the movable jaw 2, the moving device comprises a push block 5 arranged in front of the movable jaw 2 and a lead screw 6 in threaded connection with the push block 5, and the lead screw 6 penetrates through the push block 5 and one end of the lead screw is in contact with the movable jaw 2. A threaded hole 8 is provided at the bottom of the slide groove 10, a fastening screw 7 is fastened to the push block 5, and the push block 5 and the flat-nose pliers body 1 are fixedly connected by the fastening screw 7.

In order to make the push block 5 slide on the flat-nose pliers body 1 more smoothly and not easy to fall off, the bottom end of the sliding groove 10 is in an inverted T shape, and the push block 5 is provided with a connecting part corresponding to the push block.
