Embodiment

To combine accompanying drawing and embodiment that the utility model is further specified below.

Please with reference to Fig. 2-3; The rotation connection structure of the utility model comprises: the upper blocking seat 11 and the following deck 12 that are rotatably connected each other; The cavity of said upper blocking seat 11 and following deck 12 surrounds the space that twist-lock and releasing device can be installed; Said twist-lock and releasing device comprise: gear 2, support the button 4 that upper blocking seat 11 is exposed on elastic component 3 and top between said gear 2 bottom surfaces and following deck 12; The madial wall of said upper blocking seat 11 and following deck 12 cavitys is provided with the internal tooth with said gear 2 engagements, and said elastic component 3 can be with being pushed on the said gear 2 that top is positioned at upper blocking seat 11 cavitys and the bottom is positioned at time deck 12 cavitys; Also be provided with runner 5 between described gear 2 and the button 4; Said runner 5 offsets with gear 2.

Please with reference to Fig. 4; Runner 5 upper surfaces are along the guiding surface 51 that circumferentially evenly is provided with 12 same tilt angles; The clockwise direction that said guiding surface 51 is overlooked along the runner 5 tops square neck that makes progress is oblique; Be provided with stop surface 53 between the adjacent guiding surface 51, guiding surface 51 lowest parts are interval with breach 52 and supporting position 54.

Please with reference to Fig. 2, the bottom of said button 4 is also even must to be provided with 3 guiding tooth groups 42 that cooperate with said guiding surface 51 touchings, and said guiding tooth group 42 comprises 2 guiding teeth 41 that can cooperate with 2 adjacent guiding surfaces 51 simultaneously.

Please with reference to Fig. 5-9, said upper blocking seat 11 be provided with can just ccontaining said runner 5 upper blocking seat inner chamber 111, the inwall of said upper blocking seat inner chamber 111 must be provided with 3 support ledge 112 corresponding to the breach 52 of said runner 5 or supporting position 54 are even.

Please with reference to Fig. 2-12; Press the button 4 o'clock working principle: when button 4 is pressed; Said guiding tooth group 42 is close to said guiding surface 51, said runner 5 said elastic component 3 provide on turn to the position that said stop surface 53 is close to said guiding tooth group 42 under the thrust; Because guiding tooth group 42 comprises 2 guiding teeth 41 that can cooperate with 2 adjacent guiding surfaces 51 simultaneously; Make guiding tooth group 42 must have a guiding tooth 41 finally to be against the position of supporting position 54, prevented that the breach 52 that guiding tooth 41 tops are absorbed in runner 5 from causing stuck problem.Runner 5 can rotation when button 4 was pressed, and made the guiding surface 51 that lug 112 is corresponding different.
