In other embodiments, the display device can also be computer.
The power source is motor 13, and the gear drive includes the first gear axle being connected with motor 13
12, being provided with first gear axle 12 in first gear 8, first gear 8 has along the uniform gear teeth of circle.Gear drive machine
Structure also includes being provided with the second gear axle 11 being connected with torque sensor 3, second gear axle 11 to be nibbled with first gear 8
The second gear 9 of transmission is closed, second gear 9 is gear wheel, and first gear 8 is little gear, and two meshed transmission gears play deceleration
Effect.In addition, being used for for second gear 9 is 1/ with the ratio that the gear teeth of the engaged transmission of first gear 8 account for the circle of second gear 9
4, that is to say, that the engaged transmission angle of first gear 8 and second gear 9 only has 90 degree.
The pivot center of first gear axle 12 and second gear axle 11 extends in left-right direction, the gear drive
Also include left fixed plate 7 and right fixed plate 5 that left and right be arranged in parallel, left fixed plate 7 and right fixed plate 5 pass through the phase of fixing bolt 4
It is arranged with connection, fixing bolt 4 between left fixed plate 7 and right fixed plate 5 for limiting left fixed plate 7 and right fixed plate 5
The sleeve 6 of spacing.Motor 13 is fixed in left fixed plate 7, is further fixed on being used for the rotating speed of controlled motor 13 in left fixed plate 7 and is turned
To controller（Not shown in figure）.
First gear axle 12 and second gear axle 11 are by the rolling assembling of bearing 10 in left fixed plate 7 and right fixed plate 5
On, first gear 8 and second gear 9 are respectively positioned between left fixed plate 7 and right fixed plate 5.The right-hand member of second gear axle 11 and torsion
The left end drive connection of square sensor 3, the right-hand member of torque sensor 3 is connected by joint 14 with power transmission shaft 2.
The left end of second gear axle 11 stretches out left fixed plate 7 and extension axis and second gear axle is provided with external part
