In other embodiments of the present application, the number of the accommodating chambers 115 may be one or more. It is to be understood that the present embodiment does not limit the number of the accommodating cavities 115, as long as the number of the accommodating cavities 115 corresponds to the number of the guiding assemblies 130.
With continued reference to fig. 2-7, in the present embodiment, two accommodating cavities 115 are concavely disposed in parallel on the side wall of the first mounting portion 111. Providing two receiving chambers 115 in parallel can provide better space savings, resulting in a smaller housing 110.
It should be noted that, by parallel arrangement, it is meant that the two receiving chambers 115 each extend from the first mounting portion 111 toward the second mounting portion 113, and that a slight angle may be considered to be parallel arrangement, and that the parallel arrangement does not define absolute parallelism of the two receiving chambers 115, and may allow for the existence of errors.
In other embodiments of the present application, the two receiving chambers 115 may not be disposed in parallel. For example, the two accommodating chambers 115 are located in the same horizontal plane, and an included angle is formed between the two accommodating chambers 115. The included angle may be 5 °, 10 °, or other angles. It should be understood that the present embodiment does not limit that the two receiving chambers 115 must be disposed in parallel, but only allows the two receiving chambers 115 to be disposed in parallel for better space utilization.

The second chamber 123 is partially disposed at the top of the two accommodating chambers 115, so that the upper half position can be well utilized, and the volume of the housing 110 is smaller. Second, the placement at the top may complement and avoid the bottom of the storage case 310, so that the height of the dispensing device 300 is not increased as a whole.
In other embodiments of the present application, the second chamber 123 may also be partially provided with lower portions of the two receiving cavities 115.
In the present embodiment, two mounting holes 125 are provided in the mounting wall 122.
