the specific working mode of the self-locking device 6 is as follows: when the handle is not lowered, under the downward pulling force of the handle spring 63 on the lifting rod 61, one side of the ball 62 is abutted against the ball accommodating wall 612 of the lifting rod 61, and the other side passes through the ball hole 52 on the handle and is abutted against the side edge of the limit group 41; when the handle 5 is lowered to the lowest position: the ball hole 52 can be opposite to the groove 411 on the limit group, the ball 62 loses the support of the side edge of the limit group 41, the lifting rod 61 moves downwards relative to the handle 5 under the action of the tension of the handle spring 63, so that the ball 62 is pushed into the groove 411, one side of the ball 62 is abutted against the pressing wall 611 of the lifting rod 61, and the other side is abutted against the groove 411, so that the handle 5 is kept fixed;
4. after the operation is finished, the self-locking device 6 is pulled upwards, so that the self-locking device 6 is unlocked, the handle automatically moves upwards by means of the upward acting force of the lifting spring group 42, the air extraction assembly leaves the side face of the cup cover 3, and the micro switch is in a trigger state.
The method comprises the following specific steps: pulling the lifting rod 61 upwards to enable the pressing wall 611 of the lifting rod 61 to leave the ball 62, and automatically leaving the groove 411 after the ball 62 loses the pressure of leaving the pressing wall 611, so that the handle 5 can automatically move upwards under the acting force of the lifting spring set 42; after the handle 5 moves upwards, the pushing part 51 moves upwards and leaves the sucker fixing frame 71, the sucker fixing frame 71 loses the pushing force action of the pushing part 51 and automatically leaves the side surface of the cup cover 3 with the sucker 72; the vertical push rod 83 of the micro switch leaves the convex block 34 after moving upwards along with the handle 5, and the horizontal elastic push rod 82 of the micro switch automatically restores to the original state after losing the pushing force of the vertical push rod 83 of the micro switch, thereby releasing the trigger of the micro switch.
The foregoing is merely illustrative of specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the design concept shall fall within the scope of the present invention.
