Abstract

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.A kind of pliers that can maintain clamped condition, comprise two calipers be hinged together, two calipers are two binding clips of occlusion mutually in the side of jointed shaft, two calipers extend to form left clamp handle and right clamp handle at the opposite side of jointed shaft, be primarily characterized in that, described two calipers are manufactured by spring steel to form, and left clamp handle is provided with a positioning rod, backstay is drilled with some pin holes in array distribution, and in the pin hole of backstay lower end, is furnished with 1 to 2 pivot pin for subsequent use; Right clamp handle has the penetrating rectangular indexing holes corresponding with backstay, and when left clamp handle and right clamp handle are closed up, the backstay in left clamp handle can intert in rectangular indexing holes.

Description

A kind of pliers that can maintain clamped condition

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 that can maintain clamped condition, comprise two calipers be hinged together, two calipers are two binding clips of occlusion mutually in the side of jointed shaft, two calipers extend to form left clamp handle and right clamp handle at the opposite side of jointed shaft, be primarily characterized in that, described two calipers are manufactured by spring steel to form, left clamp handle is provided with a positioning rod, backstay is drilled with some pin holes in array distribution, and in the pin hole of backstay lower end, is furnished with 1 to 2 pivot pin for subsequent use; Right clamp handle has the penetrating rectangular indexing holes corresponding with backstay, and when left clamp handle and right clamp handle are closed up, the backstay in left clamp handle can intert in rectangular indexing holes.

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, two clamp handles are closed up, and the backstay in left clamp handle inserts in the locating hole in right clamp handle, and the pivot pin be furnished with in the pin hole of backstay lower end is inserted in from the hithermost pin hole in right clamp handle upper end, at this moment, form because two calipers are manufactured by alloy spring steel material, there is certain elastic force, 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.

Detailed description of the invention

At Fig. 1, in Fig. 2, a kind of pliers that can maintain clamped condition that the utility model provides, comprise two calipers be hinged together, two calipers are two binding clips (2) of occlusion mutually 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), described two calipers are manufactured by spring steel to form, left clamp handle (3) is provided with a positioning rod (5), backstay (5) is drilled with some pin holes (6) in array distribution, and in the pin hole (6) of backstay (5) lower end, be furnished with 1 to 2 pivot pin (7) for subsequent use, right clamp handle (4) has the penetrating rectangular indexing holes (8) corresponding with backstay (5), and when left clamp handle (3) and right clamp handle (4) are closed up, the backstay (5) in left clamp handle (3) can intert in rectangular indexing holes (8).

Claims

1. one kind can maintain the pliers of clamped condition, comprise two calipers be hinged together, two calipers are two binding clips of occlusion mutually in the side of jointed shaft, two calipers extend to form left clamp handle and right clamp handle at the opposite side of jointed shaft, be primarily characterized in that, described two calipers are manufactured by spring steel to form, and left clamp handle is provided with a positioning rod, backstay is drilled with some pin holes in array distribution, and in the pin hole of backstay lower end, is furnished with 1 to 2 pivot pin for subsequent use; Right clamp handle has the penetrating rectangular indexing holes corresponding with backstay, and when left clamp handle and right clamp handle are closed up, the backstay in left clamp handle can intert in rectangular indexing holes.
