Specific embodiment
This utility model is further described below in conjunction with the accompanying drawings.
Referring to as Figure 1-Figure 8, the technical scheme that this specific embodiment is adopted is：It includes cylinder 1；Described cylinder
The side wall of body 1 is sequentially provided with from top to bottom several inlet holes 2, and the inwall of inlet hole 2 is with hole lid 4, and the bottom of cylinder 1 is provided with portals
3,3 outer wall of portalling is provided with out port lid 5；It is described to enter port lid 4 and go out on port lid 5 to be equipped with retainer ring 12, retainer ring 12 be into
Port lid 4 goes out the lateral extension of port lid 5, and retainer ring 12 is connected by screw with the inwall of cylinder 1；Described cylinder 1
Inside be sequentially provided with three irony sieves 6 corresponding with inlet hole 2 from top to bottom, and each irony sieves 6 is respectively provided with
In the lower section of its correspondence inlet hole 2；Described irony sieves 6 is provided with several magnetic stripes 8, and the card that magnetic stripe 8 passes through its bottom
