Embodiment:
Below in conjunction with accompanying drawing and preferred embodiment, to according to dual-axis differential formula trigger architecture embodiment, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
Referring to Fig. 1 to Fig. 3, dual-axis differential formula trigger architecture of the present utility model, comprise axle I, axle II, housing 1, wherein: axle I is comprised of ring flange 3, support 4, the end of ring flange 3 is connected with housing 1 by bearings D 11, and support 4 one ends are connected with ring flange 3, the other end is connected with housing 1 by bearing B5; Axle II is comprised of sleeve 7, metal slip ring 9, axle 10, sleeve 7 is fixed in the end thread hole of axle 10 by bolt 8, metal slip ring 9 is set on axle 10, the axle 10 at metal slip ring 9 two ends respectively by bearing C6 be connected with support 3 one end endoporus, bearing A2 is connected with ring flange 3 endoporus, metal slip ring 9 outer circumference surfaces are provided with collets 12.
