Abstract

The utility model discloses a pair of pincers for installing a spring hoop. The pair of pincers comprises two pincer bodies which are hinged to each other, wherein a part, positioned on one side of a hinging shaft, of each pincer body is a pincer head; the two pincer heads are meshed with each other; a part, positioned on the other side of the hinging shaft, of each pincer body extends to form a handle; a gap which is matched with the ear shape of the spring hoop is formed in the head part of each pincer head; a limiting device which is used for keeping the distance between the handles is arranged between the two handles, and comprises a chain and a limiting hook plate; the chain and the limiting hook plate are connected to the two handles respectively; the chain is of a circular shape formed by end-to-end connection; the limiting hook plate comprises a connecting plate; one end of the connecting plate is connected with one of the handles, and the other end of the connecting plate extends to the direction of the other handle; a plurality of hanging hooks are arranged on the connecting plate. When the spring hoop is clamped by the pincers, two ears of the spring hoop are clamped into the gaps in the pincer heads of the pincers so as to prevent slippage. The limiting hook plate is hooked by the chain, and a clamping state is fixed, so that a worker does not need to continuously grip the pincers, and waste of effort is avoided.

Description

A kind of pliers of mounting spring clip

Technical field

The utility model relates to a kind of tonger, especially relates to a kind of pliers of mounting spring clip.

Background technology

Automotive field, for being satisfied with dissimilar flexible pipe as the needs of the connection lock rings such as bent axle vent hose, vacuum servo flexible pipe, commonly uses a kind of spring hoop.As Mu Beier spring hoop, select alloy spring steel material, centre is a cranse, cranse extends two ears, the outer environment friendly corrosion protection erosion resisting coating in addition of clip.Existing method is mainly by manually joining with two laggard luggages of ear of tooth mouth clamping stirrup of pliers, but common pliers clamps the easy slippage of this clip.As Chinese patent Granted publication number: CN201342634, in the patent document in November 11 2009 Granted publication day, a kind of slip-joint pliers are disclosed, comprise left caliper, right caliper body, left and right caliper binding clip is by straight pin cross-articulation, and left and right caliper front end is binding clip, and rear end is clamp handle; Described binding clip front end is provided with shallow tooth flat pliers mouth, at binding clip middle part, is provided with wire stripping and steel wire jaw, in binding clip rear end, is provided with carp jaw; In described left and right clamp handle posterior end, be respectively provided with groove, in left clamp handle groove, be provided with serrated knife, be provided with in-line sieve and criticize in left clamp handle groove, left clamp handle is provided with file in groove.The utility model collection various tool rolls into one and simple in structure, low cost of manufacture, is applicable to machinery and installation and maintenance and family daily life and uses.But these type of slip-joint pliers, when mounting spring clip, only rely on the shallow tooth of binding clip, are not enough to fixedly secure spring hoop, two ears of spring hoop are affected by spring restoring force, easily slippage.

Utility model content

The utility model is when overcoming mounting spring clip, and common pliers clamping stirrup holds eely deficiency, and a kind of pliers of anti-slip mounting spring clip is provided.

To achieve these goals, the utility model is by the following technical solutions:

The pliers of a kind of mounting spring clip of the present utility model, comprise two calipers that are hinged, two binding clips that two calipers are interlock in a side of jointed shaft, two calipers extend to form two handles at the opposite side of jointed shaft, two binding clip heads are provided with the breach of coupling spring hoop ear shape, are provided with the stopping means that keeps handle spacing between two handles.Binding clip position at pliers arranges breach, while using pliers fastening spring clip, two ears of clip is stuck in breach, prevents slippage when stressed.Then, the stopping means that keeps handle spacing is set between two handles, makes to encounter problems cannot Fast Installation time, workman does not need to continue to hold with a firm grip, use stopping means to keep pliers clamped condition, extenuate workers with long time on the one hand and firmly hold with a firm grip, the situation that hand is ached; On the other hand, reduce artificial de-power, unclamp the situation that pliers flies off spring hoop.

As preferably, two binding clip positions are enclosed with one deck silicagel pad.Spring hoop coating scratch while avoiding clamping.

As preferably, described stopping means comprises chain and spacing hook plate, chain and spacing hook plate are connected on two handles, chain joins end to end circular, spacing hook plate comprises a plate, connecting plate one end connecting handle, the connecting plate other end extends to another handle orientations, and connecting plate is provided with several hooks.Varying in size of different spring hoops, elastic force is different, and during clamping, handle spacing is different in size, and many hooks can meet the fixedly limit function of different distance.

As preferably, jointed shaft is provided with torsion spring, and the two ends of torsion spring are connected on two calipers.Torsion spring applies the thrust that it is opened to two binding clips.Working clearance, separated two binding clips, facilitate workman to use automatically, need not first open before use two binding clips.

The utlity model has following beneficial effect: when (1) uses pliers fastening spring clip, two ears of clip are stuck in the breach of pliers binding clip, prevent slippage; (2) with chain, hook positive stop hook plate, fix to clamp state, do not need workman to continue to hold with a firm grip, waste strength.

Accompanying drawing explanation

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

Fig. 2 is barbed portion structure chart of the present utility model.

Fig. 3 is torsion spring part-structure figure of the present utility model.
