The piston cover is internally provided with an upper pressure sleeve. A piston is equipped in the piston cover, the upper pressure sleeve and the piston cylinder. A connecting rod is provided above the piston. The middle part of the connecting rod is connected with a driven deflector rod sleeve, and the upper part is connected with a driven deflector rod. An end of the connecting rod is provided with a force-bearing bearing. The piston cover is externally provided with a cylindrical rotation jacket. An upper bearing and a lower bearing are provided between the rotation jacket and the piston cover. The bottom of the rotation jacket is provided between the driven deflector rod sleeve and the force-bearing bearing. A driving deflector rod is provided downwards and is provided in a same periphery with the driven deflector rod. A belt groove is provided outside the rotation jacket. According to the manometer piston rotation device, the pressure of physical weight is transferred to the piston through the force-bearing bearing and the connecting rod.
