The upper circular cylinder 139 is not in contact with the lifting guide rod under normal conditions, but the axial direction during installation can be ensured by referring to the relative position of the upper circular cylinder 139 and the lifting guide column 131, and the self-lubricating graphite copper bush 137 can still play a good guiding role for the guide column bush 133 after being seriously worn so as to ensure the level of the lifting support plate 134. In addition, lubricating oil is filled between the upper circular cylinder 139 and the lifting guide post 131, so that the smooth lifting can be ensured.
The lifting of the lifting base 132 on the base 1 can be achieved by connecting the lifting mechanism 13 to the lifting connecting plate and fixing the lifting mechanism 13 to the base 1.
