specifically, the winding wheel (401) is rotatably installed on the motor connecting shaft (510), and the spring D (403) generates a tensile force to enable the winding wheel (401) to move towards the inclined push plate (512); a rotating shaft is arranged in the middle of the clamping groove B (513), the spring D (403) and the inclined panel (405) are slidably arranged on the rotating shaft in the middle of the clamping groove B (513), when the switch B (511) is in a normal state, the clamping buckle B (404) of the shrinkage switch mechanism (4) is clamped with the clamping groove B (513), and further the winding wheel (401) is prevented from rotating; when the switch B (511) is pressed for a certain distance, the switch B (511) drives the inclined plane pushing plate (512) to push the inclined plane plate (405) to drive the winding wheel (401) to move towards the motor (507), and when the buckle B (404) leaves the clamping groove B (513), the winding wheel (401) rotates under the action of the elastic force of the spring B (203) to further enable the pruning unit fixing mechanism (2) to move upwards to further drive the pruning unit (1) to move upwards; when the switch B (511) is pressed for the maximum distance, the switch B (511) drives the inclined plane pushing plate (512) to push the inclined plane plate (405) to drive the winding wheel (401) to move towards the motor (507), and when the buckle B (404) leaves the clamping groove B (513) and the buckle A (402) enters the clamping groove A (509), the winding wheel (401) is driven by the motor (507) to rotate so as to wind the connecting rope (202) and pull the pruning unit fixing plate (201) downwards, and then the pruning unit (1) is driven to move downwards;
specifically, the switch B (511) with different depths is pressed down, so that the inclined plane pushing plate (512) is driven to drive the shrinkage switch mechanism (4) to complete the locking of the winding wheel (401), and the motor (507) drives the winding wheel (401) to pull the pruning unit fixing mechanism (2) to move downwards; the shrinkage switch mechanism (4) is not clamped with the clamping groove A (509) and the clamping groove B (513) by pressing the switch B (511), so that the pruning unit fixing mechanism (2) moves upwards under the action of the elastic force of the spring B (203);
specifically, through pressing switch A (504), drive belt connecting plate (506) and then drive connecting belt (304) through switch A connecting rod (505), through connecting belt (304) pulling sliding shaft (306) down move and then make bevel gear C (305) and bevel gear D (508) intermeshing, drive bevel gear C (305) and then drive sliding shaft (306) rotation through motor (507), drive sleeve (301) through sliding shaft (306) and drive transmission shaft (109) and drive scissors part (102) and accomplish the pruning.
