Zusammenfassung:The utility model relates to a novel quickly-adjusting pipe tongs- a common tool. The novel scheme can solve the problem that speed for adjusting jaw opening is too slow for the prior-art pipe tongs.The pipe tongs is mainly composed of a fixed jaw, a movable jaw, a racket wheel, a spring, a pawl, a movable pin and a connecting pin; wherein the racket wheel is a parallel double gear structure; the pawl is closely contacted with the gear wheel of racket wheel under the pressure of the spring so as to guarantee invariability of the jaw opening size. The quickly-adjusting pipe tongs has advantages that the usage method is simple; manual operation for the movable pin can separate the paw and the racket wheel, and then adjust the movable jaw opening to quickly flex until the jaw opening size is proper, thus the jaw is locked and large quantities of time can be saved.
