Detailed Description

Given by fig. 1-5, the utility model discloses an installation casing 1, dysmorphism round hole 2 has been seted up at the top of installation casing 1, dysmorphism lead screw 3 has been cup jointed in the inside activity of dysmorphism round hole 2, driven gear 10 is installed to dysmorphism lead screw 3's surface thread, the bottom joint of installation casing 1 has cardboard 4, the both sides of installation casing 1 bottom surface all are equipped with the buckle, can cooperate with cardboard 4, and it is spacing to utilize driven gear 10 to carry out, the bottom fixed mounting of cardboard 4 has recipient 5, the bottom fixed mounting of recipient 5 has sharp mouth pipe 6, the surface joint of recipient 5 has plastic card 7, the fixed surface of plastic card 7 installs push type switch 8, the top fixed mounting of installation casing 1 has protective housing 9, plastic card 7 can block in arbitrary department on recipient 5 surface, in order to satisfy different operating personnel's use custom.
