Currently, in the operation of a pumping well, due to various reasons, the abrasion of a polish rod of the pumping well has an eccentric wear phenomenon, and the eccentric wear can shorten the service life of the polish rod and shorten the repair-free period of the oil well. In order to reduce the eccentric wear degree of the polish rod, an effective means adopted at present is to improve the oil pumping unit so that the polish rod continuously rotates when reciprocating up and down in work, and further the uniform wear of the polish rod is achieved. After the improvement, the indicator diagram testing device arranged on the polished rod is required to rotate along with the polished rod, and the indicator diagram testing device is arranged on the polished rod, so that the following problems exist: the mounting hole is used as the center, the circumferential overall dimension of the mounting hole is not uniform, the space occupied by the shell on one side of the mounting hole is large, the span of two polished rods of the polished rod eye of the pumping unit is smaller than the rotating radius of the shell, and when the indicator diagram testing device rotates along with the polished rod, the shell can be blocked by the polished rod eye and is difficult to rotate.
