Abstract

The utility model belongs to benchworking tool technical field, in particular to a special vice for mounting outer circlip. The utility model discloses special outer circlip pliers comprising two plier handles and a rotation shaft. The two plier handles are respectively provided with a rotation shaft hole. The rotation shaft is mounted between the two rotation shaft holes. The two plier handles are of non-staggered form. The handle end parts of the pliers handles are respectively fixed with spring blades by rivets. The two spring blades are crossed together. The clamping end parts of the pliers handles are cylindrical pivot-ends. The utility model of outer circlip pliers has the advantages of convenient usage and high production efficiency.

Description

The outer Circlip tongs of a kind of special use

(1) described technical field

The utility model belongs to the technical field of small tool, particularly a kind ofly assembles the special vice that outer jump ring is used.

(2) background technology

In automobile production or other production process, when assembling outer jump ring, instrument commonly used is nipper plier.With the outer jump ring of nipper plier assembling, nipper plier during jump ring, gets loose outside opening easily; When nipper plier opened jump ring, exerting oneself of hand was tension force, is not easy operation.

(3) summary of the invention

The utility model is at the deficiencies in the prior art, and provide a kind of and outside assembling, during jump ring, can conveniently clamp outer jump ring, and convenient and strength-saving special vice.

The utility model is realized by following technical measures:

The utility model discloses the outer Circlip tongs of a kind of special use, include two pincers handles and a rotating shaft, two pincers handles respectively have a shaft hole, between two shaft holes rotating shaft are installed; Two pincers handles are non-staggered form; The handle end of pincers handle is fixed with spring leaf by rivet respectively, and two spring leafs intersect; The clamping end of pincers handle is a cylindrical nib.

The outer Circlip tongs of special use of the present utility model, described spring leaf, one end is a groove, and there is projection another end, and projection is inserted in the groove.

Because two pincers handles are non-staggered form, when clamping the handle end of handle when holding with a firm grip, open the clamping end of pincers handle; Otherwise, the clamping closed end of pincers handle.When outer jump ring is installed like this, more laborsaving.Simultaneously, the handle end at the pincers handle is equipped with two cross one another spring leafs, after loosing one's grip, utilizes the tension force of spring leaf, the pincers handle can be opened automatically.Respectively there is a cylindrical nib clamping end of pincers handle, can insert easily in the aperture of outer jump ring.

Therefore, outer Circlip tongs of the present utility model, have easy to use, the production efficiency height.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is made specific description

Fig. 1 is a structural representation of the present utility model

Fig. 2 is a pincers handle structure schematic diagram of the present utility model

Among the figure, 1 rivet, 2 spring leafs, 3 pincers handles, 4 rotating shafts, 5 shaft holes

(5) specific embodiment

As Fig. 1 and Fig. 2 is the specific embodiment of the utility model structural representation.The special-purpose outer Circlip tongs of present embodiment, having two pincers handles 3 and 4, two pincers of rotating shaft handle 3 respectively has and 4, two of rotating shafts is installed between 5, two shaft holes 5 of a shaft hole to clamp handle be non-staggered form.Hold with a firm grip when clamping the handle end of handle, open the clamping end of pincers handle; Otherwise, the clamping closed end of pincers handle.

It is fluted that the handle end of pincers handle 3 is fixed with the end of 2, one spring leafs of spring leaf by rivet 1 respectively, and there is projection the end of another spring leaf, and projection is inserted in the groove, and two spring leafs are intersected.

The clamping end of pincers handle is a cylindrical nib, can insert easily in the aperture of outer jump ring.

During use, two apertures of outer jump ring are enclosed within respectively on the cylindrical nib of pincers handle, catch two handle end that clamp handles with hand, compress, then jump ring has just opened, jump ring is enclosed within on the workpiece, open openhanded then, outer Circlip tongs makes pincers handle return by the tension force of spring leaf, take out from jump ring, a jump ring has just assembled.

Claims

1. the outer Circlip tongs of special use includes two pincers handles (3) and a rotating shaft (4), and two pincers handles respectively have a shaft hole (5), between two shaft holes rotating shaft are installed, and it is characterized in that: two pincers handles are non-staggered form; The handle end of pincers handle is fixed with spring leaf (2) by rivet (1) respectively, and two spring leafs intersect; The clamping end of pincers handle is a cylindrical nib.

2. the outer Circlip tongs of special use according to claim 1 is characterized in that: described spring leaf, and one end is fluted, and there is projection another end, and projection is inserted in the groove.
