Step 2: starting motor (303), the output shaft of motor (303), which rotates forward, drives driving wheel (304) to rotate forward, main
Driving wheel (304) drives the first driven wheel (307) to rotate forward by the first synchronous belt (314), and the first driven wheel (307) drives the
Two lead screws (305) rotate forward, and the second lead screw (305) drives the second nut (309) to move up along the second lead screw (305), the
Two lead screws (305) drive the second driven wheel (308) to rotate forward, and the second driven wheel (308) is driven by the second synchronous belt (315)
Third driven wheel (310) rotates forward, and third driven wheel (310) drives third lead screw (306) to rotate forward, and makes the second lead screw
(305) with third lead screw (306) rotate synchronously, third lead screw (306) drive third nut (311) along third lead screw (306) to
Upper movement, the second nut (309) and third nut (311) move up simultaneously drives fixed link (312) to move up, fixed link
(312) supporting plate (313) are driven to move up, supporting plate drives adjustable end stop (302) to rise；
Step 3: reversely shaking hand handle (25), and hand handle (25) drives the first lead screw (26) to rotate backward, the first lead screw
(26) drive the first nut (27) moved to the right along the first lead screw (26), the first nut (27) drive the second connecting rod (23) with
Second connecting rod (23) and first crossbar (21) hinged place rotate clockwise for the center of circle, and the second connecting rod (23) drives second crossbar
(22) decline, when the second connecting rod (23) and the contact of adjacent second connecting rod (23), stop shaking hand handle (25), at this time
Second crossbar (22) is in extreme lower position；
Step 4: starting motor (303), the output shaft of motor (303), which rotates backward, drives driving wheel (304) to rotate backward, main
Driving wheel (304) drives the first driven wheel (307) to rotate backward by the first synchronous belt (314), and the first driven wheel (307) drives the
Two lead screws (305) rotate backward, and the second lead screw (305) drives the second nut (309) to move down along the second lead screw (305), the
Two lead screws (305) drive the second driven wheel (308) to rotate backward, and the second driven wheel (308) is driven by the second synchronous belt (315)
Third driven wheel (310) rotates backward, and third driven wheel (310) drives third lead screw (306) to rotate backward, and makes the second lead screw
(305) with third lead screw (306) rotate synchronously, third lead screw (306) drive third nut (311) along third lead screw (306) to
Lower movement, the second nut (309) and third nut (311) move down simultaneously drives fixed link (312) to move down, fixed link
(312) supporting plate (313) are driven to move down, adjustable end stop (302) decline.
