Height adjustment mechanism and leveling adjustment device

Abstract

The present invention provides a height adjustment mechanism and a leveling adjustment device. The height adjustment mechanism is adapted to be installed between a fixed plate and a load-bearing plate for adjusting a distance between the fixed plate and the load-bearing plate, comprising: a screw rod having one end threaded into a screw hole of the load-bearing plate and the other end extending toward the fixed plate and having an arcuate surface; a gasket disposed between the screw rod and the fixed plate, a surface of the gasket facing the screw rod being in surface contact with the arcuate surface of the screw rod; and a fixing member extending through both the screw rod and the gasket and being fixed to the fixed plate. This design reduces displacement errors caused by tilt and improves the accuracy of height adjustment. The most illustrative drawing: FIG. 2
