[specific embodiment]
The technical solution of inventive embodiments is explained and illustrated below with reference to the attached drawing of the embodiment of the present invention, but following
Embodiment is only the preferred embodiment invented, and not all.Based on the implementation example in the implementation mode, those skilled in the art are not having
Obtained other embodiments under the premise of creative work are made, the protection scope of invention is belonged to.
In the following description, occur term "inner", "outside", "upper", "lower", the indicating positions such as "left", "right" or
Positional relationship, description embodiment merely for convenience and simplified description, rather than the device or member of indication or suggestion meaning
Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as the limitation to invention.
Embodiment one:
As shown in Figures 1 to 4, the present embodiment is a kind of telescoping mechanism, including fixing seat 50, and fixing seat 50 is equipped with axis
Hole, telescoping mechanism further include first rotating shaft 101, the second shaft 102, the first transmission arm 201, and first rotating shaft 101 is mounted on fixation
In the axis hole of seat 50,201 both ends of the first transmission arm are rotatablely connected with first rotating shaft 101 and the second shaft 102 respectively, and described first
