I.e. when the number of teeth of said second gear 3032 is equal to the number of teeth of said first gear 3031, the moving speed V of the driving member 401And the speed V of the movement of the functional module2Are equal. At this time, the moving speed of the function module 10 can be controlled by controlling the moving speed of the driving member 40.

Specifically, in the present embodiment, the speed at which the driving member 40 moves is V1The moving speed of the functional module 20 is V2Since the root circle diameter of the second gear 3032 is larger than that of the first gear 3031, the transmission device 30 constitutes a speed change mechanism. For example, when the second gear 3032 has a root diameter D 220, the root diameter D of the first gear 30311When 10, it can be known from the calculation that: v2＝2V1. At this time, it is shown that when the driving member 40 moves by one unit distance, the function module 10 moves by two unit distances, thereby realizing that the driving member 40 moves by a small displacement, resulting in that the function module 10 moves by a large displacement, and reducing the number of usersThe work done in the process of sliding the driving member 40 achieves the effect of saving time and labor.
