Abstract: This disclosure concerns a tool fixing mechanism including a hollow grip and a resilient clip body. The grip has a front end and a rear end. The front end is formed with a slot, while the rear end is formed with a cross-shaped socket. Two windows are respectively formed on the top and bottom walls of the rear end of the grip. The resilient clip body is located in the cross-shaped socket of the grip. The resilient clip body is formed with two lugs extending out of the windows of the grip. Therefore, if a user depresses the lugs, the resilient clip body is closed or stretched open so as to fixedly latch or release a tool inserted in the slot of the front end of the grip.

Abstract: To locate a bearing axially and concentrically on a shaft, a resiliently compressible assembly is slid along the shaft until its leading edge is restrained (e.g. by contacting a yoke at the end of the shaft), the bearing is slid along the shaft until it abuts the assembly, and a sleeve is slid along the shaft to abut the bearing. Further movement of the sleeve compresses assembly, whereupon three internally sprung fingers of the sleeve snap into corresponding detents in the shaft. Releasing the sleeve permits the assembly to exert a contrary force whereupon the finger ends engage the ends of the detents and provide axial location of the bearing. Internal cone surfaces of the bearing contact a split cone of assembly and an external cone surface of sleeve. The shaft may be part of a vehicle steering column with reach and rake adjustment.
