Embodiment Construction

[0012] figure 1 , figure 2 with image 3 It is an embodiment of the present invention. The housing of the key exchange device is composed of a base and an outer cover 1. The base is composed of a base plate 2, a backing plate 4, and inner and outer groove covers 3 on both sides of the inner and outer sides. The middle part of the bottom plate and the backing plate is dug out to form a The gear group groove 20, the inner groove cover is made up of the inner layer inner groove cover 5 and the outer layer inner groove cover 6 two layers, to increase the thickness of the inner groove cover, these base components are combined together by four fixing bolts 14 . from image 3 It shows that a locating gear 15 is installed in the gear set groove, and there is a section around the locating gear that is toothless, and the periphery of the toothless section is recessed between the tooth peaks on both sides. There are also two gears meshing with the positioning gear, one is the exchan...
