Abstract: A terminal pliers structure includes a seat, a drive mechanism, and a clamping mechanism. The clamping mechanism includes a first clamping block, a second clamping block, and a spring. In operation, the first clamping block and the second clamping block are forced to pivot in concert with each other, thereby facilitating the user operating the terminal pliers structure, and thereby saving the manual work. In addition, the first teeth of the first clamping block mesh with the second teeth of the second clamping block to enhance the clamping force between the first clamping block and the second clamping block, so that the clamped terminal head can be clamped between the first clamping block and the second clamping block rigidly and stably.

Abstract: A contraction tool includes a main body, and a pressing unit mounted on the main body. The pressing unit includes two press plates each having an upper section formed with a positioning recess and a lower section formed with a tapered face. The contraction tool further comprises a push rod moved relative to the main body and inserted into the positioning recesses of the two press plates of the pressing unit, and an urging member mounted on the push rod to move therewith synchronously and inserted between the tapered faces of the two press plates of the pressing unit. Thus, the contraction tool has an enhanced pressing force and is operated easily and conveniently.
