The utility model provides forceps, which comprise a first clamp arm and a second clamp arm, wherein the first clamp arm and the second clamp arm are respectively provided with a fixing end. The forceps are characterized in that the fixing end of the first clamp arm and the fixing end of the second clamp arm are correspondingly provided with a plurality of fixing holes respectively. The forceps further comprise a plurality of fixing parts, and the fixing holes on the first clamp arm and the corresponding fixing holes on the second clamp arm are combined together respectively by the fixing parts. The two clamp arms of the forceps are combined together by the fixing parts, and accordingly the clamp arms of the forceps can be replaced so as to save cost.

Description

Tweezers

[technical field]

The utility model relates to a kind of tweezers, the particularly a kind of tweezers that can change jig arm.

[background technology]

Tweezers commonly used at present are integrated clip with two jig arm basically, and this forceps constructions is simple, easy to use, use general in industry and life.But the jig arm of this tweezers is in use fragile, again because this tweezers be integrated, thereby whole tweezers will scrap, so just caused the waste of resource.

In view of this, the utility model provides a kind of novel tweezers, and this tweezers can be changed jig arm, thereby can save cost.

[summary of the invention]

The purpose of this utility model is to provide a kind of tweezers that can change jig arm, so that save cost.

For achieving the above object, the utility model provides a kind of tweezers, comprise one first jig arm and one second jig arm, described first jig arm and described second jig arm respectively have a stiff end, it is characterized in that, respectively offer the plurality of fixed hole on the stiff end of the stiff end of described first jig arm and described second jig arm accordingly; Described tweezers also comprise the plurality of fixed part, and it is combined fixing hole corresponding on the fixing hole on described first jig arm and described second jig arm respectively.

Preferably, described fixing hole is a circular hole.

Preferably, described fixture is supporting bolt and nut

Preferably, described fixing hole is a slot or tri-angle-holed.

Compared to prior art, the utility model is by using described fixture that two jig arm of described tweezers are combined, thereby can realize the replacing of the jig arm of tweezers, to reach the purpose of saving cost.

For making the purpose of this utility model, structural feature and function thereof there are further understanding, cooperate diagram to be described in detail as follows now:

Fig. 1 is the decomposing schematic representation of the utility model tweezers first embodiment.

Fig. 2 is the combination schematic diagram of the utility model tweezers first embodiment.

Fig. 3 is the decomposing schematic representation of the utility model tweezers second embodiment.

Fig. 4 is the combination schematic diagram of the utility model tweezers second embodiment.

[specific embodiment]

Seeing also Fig. 1 and Fig. 2, is the schematic diagram of first embodiment of the present utility model, and the utility model tweezers comprise: first jig arm 1 and second jig arm 2.Wherein, first jig arm 1 has stiff end 11, and offers two identical circular holes 111 on the stiff end 11, similarly, also has stiff end 21 on second jig arm 2, and also offers on the stiff end 21 and circular hole 111 corresponding two circular holes 211.

The utility model tweezers also comprise the fixture that first jig arm 1 and second jig arm 2 are combined, in present embodiment, the quantity of fixture is two groups, and every group of fixture is made up of a supporting bolt 3 and a nut 4, wherein, bolt 3 has head 31 and screw rod 32.

During assembling, the screw rod 32 of bolt 3 is penetrated the circular hole 111 of first jig arm 1 and the circular hole 211 of second jig arm 2 successively, and pass at screw rod 32 in the bar portion of circular hole 211 and screw on nut 4, thereby first jig arm 1 and second jig arm 2 are fixed together.

An if damage in first jig arm 1 and second jig arm 2, then nut 4 is unloaded, screw rod 32 is extracted out from circular hole 211 and circular hole 111, is got one again and have the jig arm of same circular fixing hole, with its with the jig arm of not damaging to combine to get final product according to above-mentioned number of assembling steps.

In present embodiment, offer two circular holes 111 and two 211, be to arrange the position in order to make first jig arm 1 and second jig arm, 2 relative fixed, not produce.During concrete enforcement, can certainly offer the circular hole of other quantity.

Seeing also Fig. 3 and Fig. 4, is second embodiment of the present utility model, and in present embodiment, the fixing hole on first jig arm 1 and second jig arm 2 is respectively a slot 112 and a slot 212.Be used for the fixture that slot 112 and slot 212 are combined is made up of assembly 1 and assembly 26, wherein, the main part of assembly 1 is a cuboid 51, one projection 52 is set on one end of cuboid 51, and offer a square groove 53 on its other end, and the end side surface of the groove 53 place ends of cuboid 51 is just suitable with square opening 112 and slot 212; Assembly 26 is a cuboid, and the one end just can insert in the groove 53.

During assembling, the end of the groove 53 place ends of cuboid 51 is passed slot 112 and slot 212 successively, and in the groove 53 that passes slot 212 plug-in package 26, at this moment, the part of assembly 26 is inserted in the groove 53, a part is exposed to outside the groove 53, thus with first jig arm 1 and second jig arm, 2 fixed combination in together.

Certainly, when concrete enforcement, the fixing hole on first jig arm 1 and second jig arm 2 can also be for tri-angle-holed.

Embodiment described herein manyly utilizes preferred embodiment of the present utility model, and sets forth by the mode of explanation rather than restriction here.It will be apparent to one skilled in the art that it should be apparent that, do not break away from itself under the prerequisite of the utility model spirit and scope that appended claims limits, can make many other embodiment.
