Specific embodiment
The technical solution of the utility model, but protection domain of the present utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
As shown in FIG. 1 to 3, a kind of multi gear position rotating mechanism, it includes rotating shaft 3, disk 1, plunger 2, axle is mounted
Hold 4 and jump ring 5；Disk 1 is mounted and is provided with the mounting groove 1.2 of bearing 4, the outer ring of bearing 4 is inlaid in spacing peace by interference fit
In the mounting groove 1.2 of bearing 4 of sabot 1, rotating shaft 3 passes through the inner ring of bearing 4, and spacing with jump ring 5 in case rotation stop axle 3 is exited, rotating shaft 3
It is interference fit with inner ring；Plunger 2 is arranged in rotating shaft 3, and plunger 2 includes plunger body, hoodle and spring, a part for hoodle
It is arranged in plunger body, hoodle is against plunger body end by the spring in plunger body, disk 1 is mounted according to positioning
Needs are provided with the hemispherical groove 1.1 matched with plunger 2, the quantity at least two of hemispherical groove 1.1.
Preferably, the utility model also includes damper 6, and damper 6 is arranged on and is mounted on disk 1 and and rotating shaft 3
End coordinates, and damping is provided in the rotary course of rotating shaft 3.
Preferably, the quantity of described hemispherical groove 1.1 is five.
Preferably, the annular groove for the motion of plunger 2 is provided with described limit installation disk 1, annulus trench bottom is provided with
Five equally distributed hemispherical grooves 1.1.
Preferably, the annular groove for the motion of plunger 2 is provided with described limit installation disk 1, annulus trench bottom sets half
