ABSTRACT:
A non-sectional locking buffer device. The device utilizes a screw ascending and descending principle as a buffering function, wherein ball bearings or outer screw grooves are configured on a central shaft of the buffer device to operate in coordination with inner screw grooves or ball bearings configured on an inner wall of a buffer chamber. The inner and outer screw mechanisms rely on slippage of the ball bearings in the screw grooves, to reduce a jolting force from repositioning or returning of an upright support, thereby reducing buffer malfunction.
