[0026] After the reducer is connected to the solar photovoltaic module and installed and fixed, the concentricity of the output shaft of the reducer and the connecting part is adjusted by rotating the adjustment disk 4 and rotating the four screw rods 76 respectively, thereby avoiding the problem of concentricity deviation between the reducer and the solar photovoltaic module, which is conducive to the long-term use of the reducer.

[0027] like Figure 1 and 5 A second embodiment is shown, which mainly differs from the first embodiment in that the shock absorbing assembly 6 includes a damper 61 and a connecting member 62, the damper 61 is rotatably connected to the inner surface of the circular groove 5, the connecting member 62 is fixedly connected to the annular surface of the support plate 71, one end of the telescopic rod of the damper 61 is rotatably connected to the connecting member 62, a shock absorbing spring 63 is arranged between the damper 61 and the connecting member 62, and the shock absorbing spring 63 is sleeved on the surface of the telescopic rod of the damper 61.
