Fig. 2 is a birds-eye view shown in Figure 1.

Fig. 3 is the block diagram of teeth cutter blade sheath shown in Figure 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model adhesive tape machine safety device is described in further detail:

Embodiment one: see Fig. 1, Fig. 2, shown in Figure 3, comprise the gummed paper wheel 1 on the adhesive tape machine body, solid paper piece 2 and teeth cutter blade 3, also comprise teeth cutter blade sheath 4, at the top end face of teeth cutter blade sheath 4 import and export 41 of teeth cutter blade 3 and the swing window 42 of solid paper piece 2 are arranged; Have a sheath spring 43 1 ends to cooperate with teeth cutter blade sheath 4, the other end is against on the adhesive tape machine body, and teeth cutter blade sheath 4 has certain distance with adhesive tape machine body bottom surface.So when the end user will cut off gummed paper, gummed paper was attached on the solid paper piece 2, and the gummed paper that is tightened up moves down teeth cutter blade sheath 4, and teeth cutter blade 3 exposes from the import and export 41 of teeth cutter blade sheath 4, cuts off gummed paper.This moment, gummed paper was had no progeny, and teeth cutter blade sheath 4 loses pressure return under the elastic force effect of sheath spring 43, and teeth cutter blade 3 is from import and export 41 withdrawals of teeth cutter blade sheath 4.

Embodiment two: on the basis of embodiment one, in described teeth cutter blade sheath 4, described solid paper piece 2 cooperates with teeth cutter blade sheath 4 by wheel shaft 21, and paper piece 2 can be swung in the certain angle in swing window 42 so admittedly; One fixing lug boss 6 is arranged on the adhesive tape machine body, the sub-fraction of the bottom of described solid paper piece 2 is against on the fixing lug boss 6, so when unused state, because some is stuck in the bottom of solid paper piece 2 on the fixing lug boss 6, so no matter on teeth cutter blade sheath 4, how to exert oneself, teeth cutter blade sheath 4 can not move down yet, and teeth cutter blade 3 just can not expose from teeth cutter blade sheath 4 yet.When the end user uses, cut off gummed paper, gummed paper is attached on the solid paper piece 2, the gummed paper that is tightened up forces solid paper piece 2 to rotate around wheel shaft 21, this moment, the described sub-fraction of the bottom of paper piece 2 admittedly left fixing lug boss 6, teeth cutter blade sheath 4 can be moved down, and teeth cutter blade 3 exposes from the import and export 41 of teeth cutter blade sheath 4, cuts off gummed paper.When gummed paper is had no progeny, teeth cutter blade sheath 4 loses pressure return under the elastic force effect of sheath spring 43, and teeth cutter blade 3 is from import and export 41 withdrawals of teeth cutter blade sheath 4.

Embodiment three: see Fig. 1, shown in Figure 2, on the basis of embodiment two, be fixed with shifting block 11 on the described gummed paper wheel 1, this shifting block 11 drives a link gear 5, these link gear 5 other ends cooperate with teeth cutter blade sheath 4, and the pull back spring 51 that makes these link gear 5 returns is installed in the adhesive tape machine body; At this link gear 5 deck 52 is arranged, the bottom of described teeth cutter blade sheath 4 is positioned on the deck 52 and cooperates with deck 52, and the thickness of deck 52 is greater than the distance between teeth cutter blade 3 and the teeth cutter blade sheath 4.So when the end user uses adhesive tape machine, cut off gummed paper, gummed paper is attached on the solid paper piece 2, the gummed paper that is tightened up forces solid paper piece 2 to rotate around wheel shaft 21, this moment, the described sub-fraction of the bottom of paper piece 2 admittedly left fixing lug boss 6, gummed paper wheel 1 also has and rotates counterclockwise simultaneously, also will drive link gear 5, deck 52 is moved right, the deck 52 and the bottom of teeth cutter blade sheath 4 are misplaced, teeth cutter blade sheath 4 can be moved down, and teeth cutter blade 3 exposes from the import and export 41 of teeth cutter blade sheath 4, cuts off gummed paper.When gummed paper is had no progeny, teeth cutter blade sheath 4 loses pressure return under the elastic force effect of sheath spring 43, and teeth cutter blade 3 is from import and export 41 withdrawals of teeth cutter blade sheath 4; The gummed paper wheel 1 that loses pulling force can drive solid paper piece 2 and rotate simultaneously by clockwise rotating under the effect of pull back spring 51, sets back.
