Abstract

The utility model relates to a hardware and tools, especially a take novel pliers of built-in spring device. The left and right clamp bodies of the novel clamp are movably connected in a staggered manner through rivets, and the joints of the rivets of the clamp bodies are provided with built-in spring devices for applying tension to the clamp bodies. And the opposite binding face of the rivet joint on the pliers body is provided with an annular groove concentric with the rivet hole, and the spring device is embedded in the annular groove. The beneficial effects of the utility model reside in that, change general external spring structure into built-in for the spring is difficult to lose, keeps the good and lasting tension of the pincers body, simple structure, and convenient to use, the outward appearance is more pleasing to the eye.

Description

A kind of novel pliers that has built-in spring assembly

Technical field

The utility model relates to a kind of hardware ﹠ tools, and particularly a kind of pliers belongs to hardware and makes the field.

Technical background

Existing pliers all is made up of caliper, handle, between caliper and the caliper movable interconnection together, the caliper other end is connected with handle.At the caliper rear portion or the medial surface of handle front end a projection or draw-in groove are set respectively, between two relative projections or draw-in groove, the compression spring is set, be convenient to apply tension force to caliper, make caliper keep open configuration.This structure, service time one is long, and spring drops out from projection or in the draw-in groove easily, in case there has not been the tension force that spring applied, pliers just can not open in use naturally, makes troubles to the user.

Summary of the invention

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of novel pliers that adopts built-in spring assembly to replace external spring is provided, and simplifies the structure of pliers, and easy to use, outward appearance is more attractive in appearance.

The technical scheme of the utility model pliers is: a kind of novel pliers, its left and right caliper is cross-linked by rivet is movable, it is characterized in that: described caliper is provided with the built-in spring assembly that caliper is applied tension force in the rivet junction.

Described caliper is provided with the cannelure concentric with rivet hole on the relative binding face of rivet junction, described spring assembly is a torsionspring, and torsionspring is positioned in the set cannelure of caliper.

The end pin of described torsionspring respectively fastening in cannelure on the set draw-in groove.

Described caliper end is hinged with handle.

Especially, described caliper is equipped with the elasticity fastening sheet that prevents the caliper counter-rotating with the inboard of corresponding handle junction.And described elasticity fastening sheet is fixed on the handle, the inner side in the caliper rear end, be provided with when binding clip in use, with the breach of the mutual fastening of tongue piece.

Be provided with in the described handle and hold the cavity of caliper in folding into.And, when being provided with in caliper folds into cavity and the bayonet socket of the mutual fastening of tongue piece in the outside of described caliper rear end.

The rear end of described handle is provided with bearing pin, the multiple blade of movable pivot joint on the bearing pin, and described blade also is placed in the cavity.

The beneficial effects of the utility model are, common external spring structure are changed into built-in, make that spring is not easy to lose, and keep the good and lasting tension force of caliper, and simple in structure, easy to use, outward appearance is more attractive in appearance.

Description of drawings

Accompanying drawing 1 is the front view of the utility model pliers;

Accompanying drawing 2 is for removing the front view of caliper 2A and handle among Fig. 1;

Accompanying drawing 3 is the rearview of caliper 2A among Fig. 1;

Accompanying drawing 4 is the user mode figure of the utility model pliers.

The specific embodiment

Shown in accompanying drawing 1 to 3, the front end of the utility model pliers is

caliper

2,2A, and the rear end is a handle 3, and left and right two calipers 2 of pliers, 2A link together by rivet 1, and

caliper

2,2A and handle 3 are movably connected.At caliper 2, rivet 1 junction on the 2A, two calipers 2, be equipped with the cannelure 4 concentric on the opposite face of 2A with the hole of rivet 1,4A, cannelure 4, the edge of 4A also is provided with the draw-in groove 5 that is used for fastening torsionspring 6,5A, torsionspring 6 is installed in cannelure 4, in the 4A, wherein 7 fastenings of an end pin are in draw-in

groove

5,8 fastenings of another end pin are in the set draw-in groove 5A of the correspondence position of another caliper 2A, pass through rivet 1 then with two

calipers

2,2A is riveted together, like this,

caliper

2,2A is under the effect of torsionspring 6, produce the tension force of nature, make pliers before use jaw keep open state.

Shown in the partial sectional view on the accompanying drawing 1,4, be provided with cavity 11 in the handle 3, be provided with the elasticity fastening sheet 9 that prevents caliper 2 counter-rotatings in the inboard of caliper 2 and handle 3 junctions.Elasticity fastening sheet 9 both sides are fixed on the handle 3, the tongue piece 91 part overheads that stretch out forward are at breach 10 places of caliper 2 bottoms, make caliper 2 can only make one-directional rotation with respect to handle 3, amount to and take in the handle 3, at this moment, the tongue piece fastening in caliper 2 rear ends with the set bayonet socket 12 of breach 10 opposite sides on, keep the folded position of caliper 2 and handle 3.Simultaneously, elasticity fastening sheet 9 also plays a supportive role to caliper 2, makes pliers in use, becomes between caliper 2 and the handle 3 to be rigidly connected, and when pliers does not use, is rotating flexibly connecting between caliper 2 and the handle 3.

As shown in Figure 4, the rear end of handle 3 is provided with bearing pin 20, articulate pocket knife 13, device for releasing closures 14, file 15, screwdriver 16 etc. by bearing pin 20, when these blades do not use, all fold in the cavity 11 of handle 3, and, the locking device that prevents that these blade accidents from opening can also be set on handle 3.In practical application, also be not limited to above-described blade, the blade that can dispose other as required is to satisfy different use needs.
