The specific embodiment

Embodiment one is referring to shown in Fig. 1-7, be cutting pliers, comprise binding clip 9, hinge 8, clamp handle 1 with last slice, following sheet pincers handle 3, last slice pincers handle 1 all is with gum cover 2 with following sheet pincers handle 3, binding clip 9 is steel wire binding clips, pliers head clip pore 7 is arranged, described last slice pincers handle 1 is connected a leaf spring 4 with the angle of following sheet pincers handle 3, the bottom of leaf spring 4 is fixed on down on the sheet pincers handle by a rivet 5, between leaf spring 4 and rivet cap portion, be with spring washer 6, rivet cap portion is enclosed in the gum cover 2, and the upper end of leaf spring 4 is positioned at sheet pincers handle side down at two pincers handle closure states, and the upper end of leaf spring 4 is positioned at last slice pincers handle side at two pincers handle open configurations.One of them is staight shank for described last slice pincers handle 1 and following sheet pincers handle 3, and another is to bend handle.

The course of work of the present utility model:

As Fig. 3, the adjustable springs structure adopts adjustable springs, is connected by rivet 5, leaf spring 4 and spring washer 6 on last slice pincers handle 1 of pliers, wherein between leaf spring and the rivet shaft head certain clearance is arranged, and leaf spring can be stirred, regulate in front and back.In order to make leaf spring not too loosening, between leaf spring and rivet shaft head, add a spring washer, leaf spring is adjacent on the then face of following sheet pincers handle 3, can stir adjusting in front and back again, the situation of freely falling body can not appear again in leaf spring.

Referring to Fig. 1-3, the utility model is not with spring function, not operation before use, pliers is at closure state, and leaf spring 4 is close on the side of sheet 9 under the pliers in the back, promptly leaf spring on the left side as shown in Figure 2 is to be in no spring function state, and binding clip closes up always.Referring to Fig. 4, bring into use, at first pliers is opened, shift leaf spring 4 onto front from behind then, leaf spring 4 be supported on the side of pliers last slice, promptly as shown in Figure 5 leaf spring is shifted onto the right, at this moment pliers is to be in the spring function state is arranged, and binding clip is in open configuration always.Carry out operation then, Fig. 6, Fig. 7 cut under the folder state in operation.Treat that operation finishes, shift leaf spring onto back, leaf spring 4 is close to again on the side of sheet under the pliers, binding clip is in again and closes up no spring function state, and so both safety was easy to carry again.

Embodiment two is nipper plier referring to shown in Fig. 8-13, and binding clip 9 is the nipper plier head.

Embodiment three is diagonal cutting nippers referring to shown in Figure 14-19, and binding clip 9 is the diagonal cutting nippers head.

In addition, binding clip 9 can also be the angle jaw tongs head.
