Specific implementation mode
The utility model will be further described below in conjunction with the accompanying drawings.
The structure of the utility model is as shown in Figure 1, Figure 2, Figure 3 shows, including stitching devices, the first open-and-close mechanism and the second folding
Mechanism.Stitching devices include the first nail bin 11 and the second nail bin 12.First open-and-close mechanism includes sequentially connected handle 21, first
Gear set 22, the first rack 23 and first folding gear set 24 are operated, the first folding gear set 24 is connect with the first nail bin 11.The
Two open-and-close mechanisms include that sequentially connected knob 31, second operates gear set 32, the second rack 33 and second folding gear set 34,
Second folding gear set 34 is connect with the second nail bin 12.When operation, handle 21 is pressed, passes through the first operation gear set 22, first
Rack 23 and first opens and closes the transmission of gear set 24, can control the rotation of the first nail bin 11；Turn knob 31 passes through the second operation
The transmission of gear set 32, the second rack 33 and second folding gear set 34, can control the rotation of the second nail bin 12.
