The utility model provides a device for adjusting the position of a balance block on an oil pumping unit, which comprises a connecting shaft, a first adjusting rod, a second adjusting rod, a third adjusting rod, a fourth adjusting rod and a fifth adjusting rod. The handle is arranged at the first end of the connecting shaft and can rotate around the axis of the connecting shaft relative to the connecting shaft; and the locking block is rotationally connected to the handle, and when the locking block rotates to be in clamped connection with the first gear, the locking block limits the rotatingdirection of the first gear relative to the handle around the axis of the connecting shaft. According to the utility model, the technical problems in the prior art that the operation difficulty of adjusting the position of the balance block is large and the working efficiency is low are solved. 本实用新型提供了一种调整抽油机上的平衡块的位置的装置，该装置包括：连接轴，其第一端安装有第一齿轮，其第二端安装有第二齿轮；手柄，其设于所述连接轴的第一端，且可相对于所述连接轴绕所述连接轴的轴线转动；锁定块，其转动连接于所述手柄，在所述锁定块转动至与所述第一齿
