The lifting mechanism has adjustable inner and outer angles.

Abstract

The useful solution refers to a lifting structure with adjustable inner and outer angles, comprising a positioning frame and a recessed frame. One side of the positioning frame is arranged with a connecting part, and the assembly chamber is formed inside the positioning frame and connecting part. The recessed frame is arranged inside the assembly chamber, and one side of the recessed frame is arranged with a side plate. By integrating two core functions—lift adjustment and internal / external angle adjustment—the structure can flexibly adjust the height and internal / external angles according to actual usage requirements, thereby adapting to different installation situations and application needs. The structure can adapt to workpiece machining requirements at different heights by adjusting the lifting height, and also adapt to workpiece bevel angles by adjusting the inner / outer angle without replacing different support structures. The main spindle is double-fixed by a bearing and screw B to ensure stable guidance. The connecting plate slides along the axial direction of the main axis, and the bushing is fitted with a sliding assembly against the inner wall of the recessed frame, thereby effectively preventing tilting and displacement during lifting, and improving the stability of the lifting adjustment.
