[0034] Working principle: When using the elevator buffer pile with positioning and adjustment function, the transmission slider 3 is driven to slide by rotating the adjusting screw 2, so that the transmission slider 3 drives the lower end of the supporting rotating arm 4 to move horizontally to support the buffer box 5. During operation, the upper connecting block 7 is driven to slide into the groove of the lower connecting block 6 through the contact baffle 8, so that the upper connecting block 7 pushes the supporting slide plate 9 and the first tooth plate 10 to descend, and the first tooth plate 10 drives the linkage gear 11 to rotate through the tooth block, so that the linkage gear 11 drives the second tooth plate 12 to rise and squeeze the first friction block 13.

After the upper connecting block 7 drives the lower connecting block 6 to descend, it pushes the two extrusion sliders 14 to slide horizontally, and drives the first piston column 15 through the extrusion slider 14 to push the oil to the second piston column 16, so that the second piston column 16 drives the second friction block 17 to slide to suppress and damp the lower connecting block 6 for further buffering, thereby increasing the overall practicality.
