And provided with linking bayonet socket 17, the other end of main shaft 11 is extended at the center hole 18 of cover plate 12 and in the main shaft 11 of the downside of cover plate 12
Main shaft curved surface sliding groove 16 is provided with, cover plate curved surface sliding groove 15 matches composition stopper slot body, limit with main shaft curved surface sliding groove 16
There is Universal caster 8 in the cell body of position；The bottom of main shaft curved surface sliding groove 16 is with one end junction of bearing 6 provided with rolling globule 7；Coil 5
It is connected with power line one end, the power line other end is electrically connected with direct current.
The main shaft curved surface sliding groove 16 has left side main shaft curved surface to slide cell body 161 and right side main shaft curved surface slip cell body
162；The straight line that the top that left side main shaft curved surface slides cell body 161 is formed with bottom is A, right side master with the angle that horizontal plane is formed
The straight line that the top that axle curved surface slides cell body 162 is formed with bottom is B with the angle that horizontal plane is formed；A ＜ B.The stopper slot
Body constitutes spacing sphere, the spacing sphere and ten thousand in the low order end that right side main shaft curved surface slides cell body and cover plate curved surface sliding groove
Fitted to the outer surface of ball, size is identical, plays complete position-limiting action.
The curved surface of cover plate curved surface sliding groove 15 and main shaft curved surface sliding groove 16 can designed size according to the actual requirements, accordingly
The size of Universal caster 8 is designed, Universal caster 8 is the ball bead being made using stainless steel.
Main shaft 11 is rotated in one direction when coil 5 is powered, and curved surface of the Universal caster 8 along spacing cell body is rotated, when ten thousand
When turning to the low order end of spacing cell body to ball 8, the main shaft curved surface sliding groove and cover plate curved surface sliding groove 15 of outer surface contact
Spacing sphere is constituted, main shaft 11 is limited, stopped operating.Because total radian of cover plate curved surface sliding groove 15 is 180 °, so main
Axle 11 is rotated up to angle for 180 °.Because the electricity that coil 5 leads to is direct current, so when main shaft 11 goes to maximum angle, simply
It is limited and stops operating, without resets.
Including secondary rotary magnet 2：Secondary rotary magnet 2 has yoke 4, coil 5, countershaft 21, auxiliary coverplate 24 and rolled small
