The invention provides a simple hoisting device structure which comprises a support, an arc pressing block and a hoisting ring screw. The simple hoisting device structure is characterized in that the support is composed of a lower transverse rod, an upper transverse rod and a connecting rod, and the lower transverse rod and the upper transverse rod are connected through the connecting rod; the included angle between the lower transverse rod and the connecting rod is smaller than or equal to 90 degrees, and the lower transverse rod and the upper transverse rod are located on the same side; the arc pressing block is arc, a hollow groove is formed in the middle of the arc pressing block, and the hollow groove and the upper transverse rod are identical in width; the hollow groove is used for being assembled with the upper transverse rod, and a clearance fit mode is adopted; the arc pressing block is connected with the upper transverse rod in a fastened mode through a screw, and the hoisting ring screw is mounted at one end of the arc pressing block. The simple hoisting device structure can be used for hoisting workpieces of different sizes and thicknesses, and is good in adaptability, safe and reliable.
