The utility model discloses a probe scanning survey mechanism for the rotary device rotatory with making the insulator cooperates, including rotary driving mechanism, sharp actuating mechanism, probe bracket and accuracy of measurement, rotary driving mechanism's output shaft with straight line actuating mechanism's kinematic axis is connected, the first end of probe bracket with the straight line actuating mechanism connect, the second of probe bracket end with accuracy of measurement connects. Probe scanning survey mechanism need not additionally to design the spin control of insulator, and motion control is simple, can realize the all standing scanning survey to the insulator surface. After the scanning survey finishes, can be rotatory with the probe bracket, making the probe bracket press close to insulator surface charge, to measure the cavity shell of experimental apparatus inboard, and simple structure is compact, it is small to occupy, save the experimental apparatus inner space, reduces the air consumption of experimental apparatus, shortens the run time.
