Below in conjunction with accompanying drawing, the utility model is described in further detail.
Detailed description of the invention
As shown in Figure 1, a kind of slide fastener being convenient for changing pull head, comprise pull head 1, two chain bands 2 with chain tooth 3, above only 32 and lower only (not shown), only 32 be at least arranged on the chain tooth 3 of a chain band 2 on described, structure is simple, decreases the procedure in production process, improve production efficiency significantly, greatly reduce production cost, effectively can prevent the slippage of pull head 1 simultaneously, well ensure the normal use of slide fastener.
As shown in Figures 2 and 3, described chain tooth 3 comprises end tooth 31, described end tooth 31 is positioned at the end of chain tooth section, end tooth 31 is provided with the through hole 311 running through end tooth 31 end face and bottom surface, in described through hole 311, installation is described above stops 32, the end tooth 31 of described two chain bands 2 is equipped with and stops 32, can better prevent the slippage of pull head 1, well ensures the normal use of slide fastener; Stop 32 on described and comprise siphunculus 321, stage clip 325 and block 322, described block 322 is arranged on siphunculus 321 opening two ends, described stage clip 325 is positioned at the inner chamber of siphunculus 321, two ends and the block 322 of stage clip 325 offset, on described, only the end of 32 is stretched out from chain tooth 3 end face and/or bottom surface, upper only 32 stop advancing of pull head 1 with offseting from the Duan Nengyu pull head 1 that stretches out of chain tooth 3 end face and/or bottom surface, described upper only 32 the section of stretching out can be retracted in chain tooth 3 under the effect of pressing force.
