Concrete operations are as follows: when large arm 30 turns clockwise, and first drives motor 2211 to be rotated through first counterclockwise
Gear 2212 and the second gear 2215 drive the second drive shaft 2214 to rotate, and thus drive large arm 30 to turn clockwise;Simultaneously
Second drives motor 2236 to drive the first threaded rod 2235 to rotate by the first worm screw 2237 and the first worm gear 22351, drives the
Two gripper shoes 2234 and the first gripper shoe 2233, to left movement, stop ratchet 2232 the most clockwise and to left movement and are resisted against up time
On pin ratchet 2231, so prevent from large arm 30 and turn clockwise inversely;
When large arm 30 rotates counterclockwise, first drives motor 2211 to turn clockwise by the first gear 2212 and second
Gear 2215 drives the second drive shaft 2214 to rotate, and thus drives large arm 30 to rotate counterclockwise;3rd drive motor simultaneously
2226 drive the second threaded rod 2225 to rotate by the second worm screw and the second worm gear 22251, drive the 4th gripper shoe 2224 and the
Three gripper shoes 2223 move right, and stop ratchet 2222 the most counterclockwise and move right and be resisted against on ratchet 2221 counterclockwise, this
Sample prevents from large arm 30 and rotates against pin reverse;
When large arm 30 turns clockwise, ratchet 2221 counterclockwise reclaims to the left;When large arm 30 rotates counterclockwise, up time
Pin ratchet 2231 reclaims to the right, does not affect the normal rotation of large arm 30.
