Description

A kind of pliers

Technical field

The utility model relates to a kind of hand-operated tools, relates to a kind of pliers that workpiece can be made to keep clamped condition in particular.

Background technology

Existing pliers can not Automatic-clamping need processing workpiece, it mainly makes workpiece maintain the state of clamping by the grip of operator to two clamp handles, when operator also will process another operation in the process completing this operation, just pliers must be put down, now be applied on two handles without pressure, the workpiece be originally clamped will come off due to the lax of jaw.When operator then will complete this procedure, re-use pliers clamping work pieces again, had a strong impact on the operating efficiency of operator like this.

Utility model content

For above-mentioned Problems existing, the utility model provides a kind of pliers, and this pliers can maintain the clamped condition of workpiece, improves the operating efficiency of operator.

For achieving the above object, the technical scheme that the utility model is taked is, a kind of pliers, comprise two calipers be hinged together, described two calipers are manufactured by spring steel to form, and two calipers are two binding clips of occlusion in the side of jointed shaft, and two calipers extend to form left clamp handle and right clamp handle at the opposite side of jointed shaft, left clamp handle is provided with some in the progressive backstay increased of display distribution, the top of backstay is provided with pin hole; Right clamp handle has the penetrating rectangle locating slot corresponding with backstay; 1 to 2 pivot pin matched with pin hole is fastened at the end of right clamp handle.

The utility model is reasonable in design, structure is simple, when operating this pliers, first workpiece is placed in the jaw of two binding clips, firmly hold left clamp handle and right clamp handle, now, jaw just can clamp workpiece, and two clamp handles are closed up, backstay in left clamp handle inserts in the locating slot in right clamp handle, fastening in the pin hole that the pivot pin of right clamp handle end is inserted in a minimum backstay, at this moment, just workpiece can be maintained the state of clamping; When taking off workpiece, again firmly holding left clamp handle and right clamp handle, pivot pin being extracted in the pin hole of backstay, unclamps both hands, now, workpiece just can take out from jaw.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is knot schematic diagram of the present utility model.

In figure: 1, jointed shaft; 2, binding clip; 3, left clamp handle; 4, right clamp handle; 5, backstay; 6, pin hole; 7, locating slot; 8, pivot pin.

Detailed description of the invention

In FIG, a kind of pliers that the utility model provides, comprise two calipers be hinged together, described two calipers are manufactured by spring steel to form, two calipers are two binding clips (2) of occlusion in the side of jointed shaft (1), two calipers extend to form left clamp handle (3) and right clamp handle (4) at the opposite side of jointed shaft (1), and left clamp handle (3) is provided with some in the progressive backstay (5) increased of display distribution, the top of backstay (5) is provided with pin hole (6); Right clamp handle (4) has the penetrating rectangle locating slot (7) corresponding with backstay (5); 1 to 2 pivot pin (8) matched with pin hole (6) is fastened at the end of right clamp handle (4).
