The proximity sensor 6 is connected to an external controller. When the push rod 4 cannot push the product, the push rod 4 moves in a direction close to the proximity sensor 6 so that the push rod 4 contacts the proximity sensor 6. When the proximity sensor 6 detects that the push rod 4 contacts the proximity sensor 6, it sends a signal to the controller, and the controller can send a signal to the alarm to sound an alarm.

[0025] Specifically, such as Figure 4 As shown, the push rod 4 includes a first push rod portion 41, a second push rod portion 42, and a third push rod portion 43. The diameter of the second push rod portion 42 is larger than the diameters of the first push rod portion 41 and the third push rod portion 43. The through slot includes a first through slot portion, a second through slot portion 32, and a third through slot portion 33. The diameter of the second through slot portion 32 is larger than the diameters of the first through slot portion and the third through slot portion 33. Furthermore, the diameter of the second push rod portion 42 is larger than the diameters of the first through slot portion and the third through slot portion 33, preventing the push rod 4 from moving away from the position sensor under the elastic force of the spring 5. The second push rod portion 42 is located within the second through slot portion 32, and the spring 5 is located within the second through slot portion 32. Driven by the elastic force of the spring 5, the second push rod portion 42 is positioned at the end of the second through slot portion 32 near the first through slot portion.

For example, if the product is square, the shape of the limit space enclosed by the limit assembly 8 is square; for another example, if the product is round, the shape of the limit space enclosed by the limit assembly 8 is round. In this embodiment, if the product is square, the shape of the limit space enclosed by the limit assembly 8 is square.
