The invention discloses a crankshaft mechanism of a double-support piston compressor and the piston compressor. The crankshaft mechanism comprises a crankshaft body, wherein the crankshaft body comprises a main shaft, an auxiliary balance block, an eccentric shaft, a receding section and an auxiliary shaft which are fixedly connected in sequence from bottom to top, the axis of the main shaft coincides with the axis of the auxiliary shaft, the receding section is cylindrical, the upper end of the receding section is fixedly connected with the lower end of the auxiliary shaft, and the lower end of the receding section is fixedly connected with the upper end of the eccentric shaft. The crankshaft mechanism adopts the cylindrical receding section, the minimum thickness of an oil hole is large, no overturning moment exists, the strength is improved, the operation is reliable, and the service life of the crankshaft mechanism is prolonged. 本发明公开一种双支撑活塞压缩机的曲轴机构及活塞压缩机，该曲轴机构包括曲轴本体，所述曲轴本体包括由下到上依次固定连接的主轴、副平衡块、偏心轴、避让段以及副轴
