Abstract
A hinge has a pivot assembly and a holding assembly. The pivot assembly has a securing panel, a connecting seat, a pivot shaft, and two positioning sets. Each of the positioning sets has a positioning ball and a silencing positioning element filled with lubricating grease. The holding assembly has two holding sheets holding the pivot shaft. With the holding sheets and the pivot shaft abutting each other with tooth or embossed surfaces, friction between the holding sheets and the pivot shaft is increased. Thus, the pivot shaft and the holding sheets do not pivot relative to each other easily. The lubricating grease in the silencing positioning elements can be smeared on the positioning balls, such that the positioning balls can smoothly roll on the pivot shaft without abrasion and no noise will occur.
