DETAILED DESCRIPTION
[0014] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments.
[0015] As Figs. 1-3 shown, the grating gear linkage type roller switch, including roller 1, gear elastic sheet 2, grating gear 3 and roller support 4, grating gear 3 is connected through detachable mode and roller 1 to form a whole and then is rotationally connected with roller support 4, roller 1 side has annular wave type gear part 101, and wave type gear part 101 is located at the side close to grating gear 3, gear elastic sheet 2 is installed on roller support 4, gear elastic sheet 2 has positioning protrusion 201 on it, and positioning protrusion 201 can be clamped into any one valley part of wave type gear part 101, and positioning protrusion 201 and wave type gear part 101 cooperate, which is the prior art.
[0016] Roller 1 side has connecting groove 102, and connecting groove 102 is located at the same side with wave type gear part 101, grating gear 3 has guide column 301 and connecting column 302 on it, the size of guide column 301 is less than the size of connecting column 302, and connecting column 302 can be tightly matched with connecting groove 102, when installing, guide column 301 plays a guiding role, so that connecting column 302 and connecting groove 102 are tightly matched to realize more smoothness.
