The invention discloses a four-connecting-rod mechanism for a trolley pole, and relates to the technical field of trolley buses. The four-connecting-rod mechanism comprises a base plate and a supporting base connected with the base plate. A large arm and a first connecting rod are connected to the supporting base. The first connecting rod is connected with a second connecting rod. A third connecting rod is connected between the second connecting rod and the large arm. A spring is connected between the large arm and the supporting base. Due to the fact that force applied by the spring on the large arm can be controlled by adjusting the lengths of the second and third connecting rods, the large arm can ascend and descend at different speeds to carry out active net touch and active net disengagement work, and meanwhile a trolley bus can be effectively prevented from being disengaged from a net in the driving process.
