Embodiment
Like Fig. 1, shown in 3, comprise shell 1, output shaft 3, power shaft 2, lower flange 4, upper flange 5, output sleeve 6, lock-screw 7, drag link sleeve 8, pull bar 9, connecting lever 10, compression spring 11.
Coaxial from bottom to top overlapping power shaft 2 and the output shaft 3 of being provided with in the above-mentioned shell 1.Lower surface and upper surface that the outer end of power shaft 2 and output shaft 3 is stretched out shell 1 respectively.
Concrete: the lower surface of shell 1 is stretched out in the lower end of power shaft 2, is connected with axle sleeve a through lower flange 4 between the lower surface of output shaft 2 and shell 1.The lower end axis body of output shaft 3 is partially submerged into the axis hole at center, power shaft 2 upper end, and between is provided with axle sleeve c, and the upper surface of shell 1 is stretched out in the upper end of output shaft 3, is connected with axle sleeve b through upper flange 5 between output shaft 3 and shell 1 upper surface.
Be connected with output sleeve 6 through key outside the output shaft 3, and be locked by lock-screw 7.The lower surface of output sleeve 6 is connected through bayonet arrangement with power shaft 2 upper ends.
The bayonet socket concrete structure is:
Like Fig. 2,4,5,6, shown in 7, the lower surface of output sleeve 6 is symmetrical set a pair of output shaft claw 61, and the angle that output shaft claw 61 both sides and its axle center form is 60 °, forms draw-in groove 62 between the adjacent output shaft claw 61; The upper surface of power shaft 2 is symmetrically arranged with a pair of arc-shaped slot 21, forms convexity 22 between the adjacent arc-shaped slot 21, and the angle that the both sides of arc-shaped slot 21 and its axle center form is 150 °.Output shaft claw 61 embeds in the arc-shaped slot, and along power shaft, the free rotating certain angle in output shaft axle center, this angle is 90 °.
One drag link sleeve 8 also is installed in the shell 1, the pull bar 9 that is slidingly connected in the drag link sleeve 8, an end of pull bar 9 is hinged with the connecting lever 10 that is fixed on the output sleeve 6, and compression spring 11 is installed on the pull bar 9.In the present embodiment, pull bar 9 comprises rod head and pull bar body, and an end and the connecting lever of rod head are hinged, and the other end is threaded with the pull bar body, and at the other end of pull bar body the adjusting keyway is set.
