It should be noted that, in the present application, the positioning structure 5 is not specifically limited, as a preferred embodiment of the present application, as shown in fig. 2, the positioning structure 5 includes a stop portion 51 disposed on a side wall of the transmission shaft 4 and limit switches 52 disposed on a top end and a bottom end of an inner wall of the extension portion, and the limit switches 52 are connected to the motor 3, and when the transmission shaft 4 is located in the first position and the second position, the stop portion 51 is respectively abutted to the two limit switches 52.

The positioning structure 5 is arranged to comprise the stop part 51 arranged on the side wall of the transmission shaft 4 and the limit switch 52 arranged on the top end and the low end of the inner wall of the extension part, and the limit switch 52 is connected with the motor 3, so that when the transmission shaft 4 moves upwards to a first position, the stop part 51 is abutted with the limit switch 52 on the top end, and the limit switch 52 is triggered, and the limit switch 52 controls the motor 3 to stop rotating or reversing, so that the condition that the transmission shaft 4 continues to move upwards to cause damage to a machine body is avoided; meanwhile, when the transmission shaft 4 moves downwards to the second position, the stop part 51 is abutted against the limit switch 52 at the bottom end, so that the limit switch 52 is triggered, the limit switch 52 controls the motor 3 to stop rotating or reversing, the condition that the transmission shaft 4 continues to move downwards to cause damage to a machine body is avoided, meanwhile, the whole control is accurate, the control logic is simple, and the reliability of the machine operation is ensured.

The technical solution protected by the present utility model is not limited to the above embodiments, and it should be noted that, the combination of the technical solution of any one embodiment with the technical solution of the other embodiment or embodiments is within the scope of the present utility model. While the utility model has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
