The invention relates to a digital distribution tightening pliers directed at the connection of hardware of a digital distribution system. The pliers comprise five function structures of pliers handles, a fixing shaft, pliers heads, elbows and a circular jaw. The pliers handles are in a splayed arc shape, of the pliers heads and the pliers handles are opposite in moving directions and connected through the fixing shaft. The pliers heads are connected with the elbows, and the circular jaw is formed in the elbows. The pliers are used for helping completing mounting and dismounting of 2M cables and 2M connection rings on a digital distribution frame. By adding the elbows, the jaw direction is changed, and the jaw shape is changed, so that the jaw can be tightly snapped with a 2M head conveniently.
