[ detailed description ] embodiments

Example (b):

referring to fig. 1 to 3, the present embodiment is a rack and pinion type pivot device 100 with a telescopic function, which includes a first rotating member 1 having a first rotating shaft 11 fixedly disposed at one side, a second rotating member 2 disposed opposite to the first rotating member 1 and having a second rotating shaft 21 fixedly disposed at an opposite side, a first set of gears 3 fixedly disposed on the first rotating shaft 11, a second set of gears 4 fixedly disposed on the second rotating shaft 21, an end connecting member 6 connecting the same ends of the first rotating shaft 11 and the second rotating shaft 21 and surrounding the same to form a telescopic space 5, and a telescopic movable plate 7 located in the telescopic space 5 and driven by the first set of gears 3 and the second set of gears 4 to perform telescopic motion.

The front and rear side surfaces of the telescopic movable plate 7 are provided with racks 71 engaged with the first group gear 3 or the second group gear 4.

The first rotating member 1 and the second rotating member 2 have the same structure and each include a connecting block 12 fixed at the middle of the first rotating shaft 11 or the second rotating shaft 21, and a mounting plate 14 connected with the connecting block 12 through a connecting rod 13. The mounting plate 14 can be used to mount other structural components or functional structural members.

The first group of gears 3 or the second group of gears 4 are provided with two gears which are respectively arranged at the left side and the right side of the connecting block 12.
