Description

Labor-saving plier with adjustable spring

Technical field

The present invention relates to a kind of hand-operated tools, particularly a kind of instrument pincers.

Background technology

Known instrument pincers are made up of two pincers handles and hinge, tradition band spring forceps class, and spring all is to be fixed on the pliers to regulate, finish the back jaw in use is to be in open configuration always, so carry very inconvenient, particularly very dangerous.

Summary of the invention

In order to overcome the deficiency of existing instrument pincers, the present invention provides a kind of labor-saving plier with adjustable spring, solve the conventional tool pincers and carry inconvenience, unsafe technical problem.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of labor-saving plier with adjustable spring comprises binding clip, hinge and last slice pincers handle, sheet pincers handle down, and last slice pincers handle clamps handle with following sheet and all is with gum cover, it is characterized in that:

Said last slice pincers handle is connected a leaf spring with the angle of following sheet pincers handle; The bottom of leaf spring is fixed on down on the sheet pincers handle by a rivet; Between leaf spring and rivet cap portion, be with spring washer; The upper end of leaf spring is positioned at sheet pincers handle side down at two pincers handle closure states, and the upper end of leaf spring is positioned at last slice pincers handle side at two pincers handle open configurations.

Said last slice pincers handle clamps handle with following sheet, and one of them is a staight shank, and another is curved handle.

Said binding clip is steel wire binding clip, nipper plier head, angle jaw tongs head or diagonal cutting nippers head.

Said rivet cap portion is enclosed in the gum cover.

Beneficial effect of the present invention is following:

The present invention has good hand touch, the characteristics that power transmission is good, and its spring is adjustable, and is laborsaving, convenient, and other pincers class traditional with market compares, and shears grip and saves 50%.When using this operation, be adjusted to adjustable springs and have band spring function state, use and render a service highly, after the end of job, be adjusted in the state of no spring function to adjustable springs, make jaw be in closed condition, so carry convenient, safer.Finishing the back jaw in use can be in closed condition always, and solve the conventional tool pincers and carried inconvenience, unsafe technical problem, Nover practical of the present invention, the scope of application is wide, can be applicable to electrician, pincers worker, machinery, vehicle maintenance, open-air installation etc.

Sheet pincers handle, 4-leaf spring, 5-rivet, 6-spring washer, 7-pliers head clip pore, 8-hinge, 9-binding clip under last pincers of Reference numeral: 1-handle, 2-gum cover, the 3-.

The specific embodiment

Embodiment one is cutting pliers referring to shown in Fig. 1-7, comprises binding clip 9, hinge 8 and last slice pincers handle 1, sheet pincers handle 3 down; Last slice pincers handle 1 all is with gum cover 2 with following sheet pincers handle 3, and binding clip 9 is steel wire binding clips, and pliers head clip pore 7 is arranged; Said 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, and between leaf spring 4 and rivet cap portion, be with spring washer 6, rivet cap portion is enclosed in the gum cover 2; 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 said last slice pincers handle 1 and following sheet pincers handle 3, and another is to bend handle.

The course of work of the present invention:

Like 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 present invention is not with spring function before use, not operation, and pliers is at closure state, and leaf spring 4 is close on the side of sheet 9 under the pliers in the back, and leaf spring on the left side promptly 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 open pliers; Shift leaf spring 4 onto front from behind then, leaf spring 4 is supported on the side of pliers last slice, the right of shifting leaf spring onto promptly as shown in Figure 5; 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.
