[0004] By setting up a safety protection structure for the tower-type oil pumping unit guide device, the guide mechanism of the tower-type oil pumping unit is structurally changed. However, there may be a state where the belt and the guide wheel cannot fit tightly together. This will cause the belt to be offset and unstable when sliding on the guide wheel, causing the belt to shake, which may pose a safety hazard.

At the same time, the working principle of the driving device 2 is the same as that of the prior art.

[0030] The middle of the slider 804 is connected with a clamping rod 805, and the surface of the clamping rod 805 is sleeved with a first spring 806.
