[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] As Figure 1 and Figure 5 shown, the pliers wrench includes a plier body 1, a first jaw arm 2 and a movable jaw head 3. A second jaw arm 4 and a fixed jaw head 5 are fixedly arranged on the plier body 1. The movable jaw head 3 is slidably arranged on the plier body 1, specifically realized through the slide groove 6 arranged on the plier body 1. The first jaw arm 2 is hinged on the plier body 1, so that the first jaw arm 2 can swing relative to the plier body 1.

[0023] In order to realize the position adjustment of the movable jaw head 3, a plurality of card slots 7 are arranged at intervals on the side of the movable jaw head 3. Correspondingly, a plurality of blocks 8 are arranged at the end of the first jaw arm 2. These blocks 8 and the card slots 7 are arranged correspondingly. When the first jaw arm 2 swings, the blocks 8 will interact with the card slots 7, thereby driving the movable jaw head 3 to approach or move away from the fixed jaw head 5 in the slide groove 6.

[0024] Compared with the existing pliers wrench, by arranging a plurality of card slots 7 and blocks 8, the adjustment distance of the movable jaw head 3 can be increased, thereby bringing convenience in use and improving the use experience.

[0025] Furthermore, in order to enhance the cooperation stability between the block 8 and the card slot 7, the card slot 7 is arranged to extend inwards along the side of the movable jaw head 3, and card projections 9 are formed between the card slots 7.
