Disclosed is a telescopic swing structure and an electric bubble bar, comprising a swing scaffold (11) and a supporting part (12), wherein three studs are formed at the back end of the swing scaffold (11), the outer side of the stud is provided with a spring (13), the supporting part (12) is fixed on a shell (14) of the electronic equipment, and the supporting part (12) is located at the back of the swing scaffold (11), the supporting part (12) is provided with three through holes (121) corresponding to the studs, the aperture of the through holes (121) is greater than the diameter of the studs and less than the diameter of a spring (13), the supporting part (12) is also provided with three limiting screws (14) corresponding to the studs, the limiting screws (14) are screwed into the corresponding screw holes (121) of the studs through the corresponding through holes (121), so as to make the spring (13) be limited between the swing scaffold (11) and the supporting part (12). The telescopic swing structure utilizes the flexibility of the spring (13), which makes the swing scaffold (11) of the head part of the electronic equipment be capable of being tilted to a certain angle after arbitrarily compressing.Linvention concerne une structure télescopique oscillante et une barre de bulles électrique, comprenant un échafaudage oscillant (11) et une partie de support (12), trois plots étant formés au niveau de lextrémité arrière de léchafaudage oscillant (11), le côté extérieur du plot est doté dun ressort (13), la partie de support (12) est fixée sur une coque (14) de léquipement électronique, et la partie de support (12) est située à larrière de léchafaudage oscillant (11), la partie de support (12) est dotée de trois trous traversants (121) correspondant auxdits plots, louverture des trous traversants (121) est plus grande que le diamètre des plots et moins grande que le diamètre dun ressort (13), la partie de support (12) est également dotée de trois des vis de fin de c
