Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
The structure of the present invention as shown in Figure 1, Figure 2, Figure 3 shows, including stitching devices, the first open-and-close mechanism and the second opening-closing machine
Structure.Stitching devices include the first nail bin 11 and the second nail bin 12.The handle 21, first that first open-and-close mechanism includes being sequentially connected is grasped
Make gear train 22, the first rack 23 and the first folding gear train 24, the first folding gear train 24 is connected with the first nail bin 11.Second
Open-and-close mechanism includes the operation of knob 31, second gear train 32, the second rack 33 and the second folding gear train 34 being sequentially connected, the
Two folding gear trains 34 are connected with the second nail bin 12.During operation, handle 21 is pressed, passes through the first operation gear train 22, the first tooth
