[0002] The three-prong bearing is a special type of rolling bearing, mainly used in applications requiring high load-carrying capacity and good self-aligning ability. The three-prong bearing has three rollers or spherical rolling elements, which are distributed in a triangular shape between an inner ring and an outer ring. Due to its design, the three-prong bearing can automatically adjust to a certain extent to compensate for the misalignment between the shaft and the housing. The three-prong design enables the bearing to exhibit high load-carrying capacity when subjected to radial loads and a certain degree of axial loads.

[0010] By adopting the technical scheme, the threaded rod can rotate in the interior of the threaded hole, thereby realizing change of the vertical direction displacement.

[0011] Preferably, the diameter of the threaded rod is greater than the diameter of the connecting rod.

[0012] By adopting the technical scheme, the threaded rod can be extruded and fitted with the outer wall of the connecting rod in the displacement process, thereby quickly positioning and fixing the position of the connecting rod.

[0013] Preferably, the calibration mechanism further comprises a handle fixedly connected to the top end of the threaded rod.
