[0033] Working principle: First, when clamping an object through the carp joint jaw 1, the length of the lever arm can be changed through different lengthening methods to make the use of the carp joint pliers more labor-saving. The positioning block 306 can be pulled out from the positioning slot 305 so that the adjusting slide block 307 can be adjusted. The adjusting slide block 307 is slid along the adjusting slot 303 by stretching the block 304 until it is engaged with the sliding block 302. After the adjustment is completed, the position is re-fixed by the positioning block 306. If the length is not enough after adjustment, the folding rotating block 401 can be rotated and expanded along the opening and closing slot 402 The folding rotating block 401 is opened until the engaging hook block 407 engages with the engaging adjustment groove 406. When it is needed to be opened, the opening and closing adjustment shaft 408 can be pulled outward.
