Abstract

A reinforcing pipe wrench comprises a movable jaw, a wrench body, an adjusting screw nut, a fixing jaw, a fixed wrench handle, a movable wrench handle, and is characterized in that a spring ring is arranged between the tail part of the fixed wrench handle and a fix cap, and the spring ring is used for clamping the movable wrench handle radially. Therefore, the structure is simple, the component processing technique is simple, the cost is low, the assembling is very easy, the using is flexible, convenient, and reasonable, and the reinforcing pipe wrench is particularly suitable for being used in oil field and used for pipeline mounting and maintenance.

Description

Boost pipe tongs

Technical field:

The utility model relates to hand tools---the pipe wrench of a kind of clamping and rotation round steel pipe class workpiece, particularly a kind of Boost pipe tongs.

Background technology:

Pipe wrench is the hand tools of a kind of clamping and rotation round steel pipe class workpiece, through being usually used in connection or operations such as detaching pipelines and maintenance.At present, China generally uses and effect Boost pipe tongs preferably, is made up of moving jaw, regular jaw, adjusting nut, caliper, sleeve pipe and boosting-rod.By rotating adjusting nut, moving jaw moves forward and backward along caliper, the size of holding diameter with this adjustable pipe clamp; Establish a locating ring at the sleeve pipe afterbody, be provided with a jump ring in the locating ring, jump ring radially clamps boosting-rod.Though this structure can be implemented the location to boosting-rod,, the strict complexity of the processing technology of jump ring and locating ring, the processing cost height, and it is also very difficult that jump ring is installed in locating ring, and make Boost pipe tongs assembling difficulty, cost up.

Summary of the invention:

The purpose of this utility model just provides a kind of simple in structure, the operation of parts processing technology, and cost is low, and very easily assembling, Boost pipe tongs flexible and convenient to use.

The purpose of this utility model is achieved in that it is made up of moving jaw, caliper, adjusting nut, regular jaw, fixing pincers handle, adjustable clamp handle, it is characterized in that between the afterbody of fixing the pincers handle and locking cap a turn being set, turn radially clamps the adjustable clamp handle.Along with the axial stretching of adjustable clamp handle in fixing pincers handle, produce frictional force between the outer wall of turn and adjustable clamp handle, the adjustable clamp handle is located in fixing pincers handle automatically at any time, flexible flexibly.

The advantage that the utility model compared with prior art has is: owing to be provided with turn between the afterbody of fixing the pincers handle and locking cap, turn radially clamps the adjustable clamp handle, along with the axial stretching of adjustable clamp handle in fixing pincers handle, produce frictional force between the outer wall of turn and adjustable clamp handle, thereby assurance adjustable clamp handle is located at any time automatically in fixing pincers handle; Locking cap and turn can stop effectively that the oil stain and the silt that are bonded on the adjustable clamp handle are brought into fixing pincers handle, and the adjustable clamp handle can be stretched in fixing pincers handle flexibly; And simple in structure, the parts processing technology is simple, and cost is low, and very easily assembling, and is flexible and convenient to use.

Below in conjunction with accompanying drawing the utility model is made concrete implementation:

In the drawings, the utility model is made up of moving jaw, caliper, adjusting nut, regular jaw, fixing pincers handle, adjustable clamp handle.Regular jaw is fixed in caliper by rivet; Moving jaw is contained in the caliper by adjusting nut; The fixing pincers of tubular type handle front end is fixed by screw thread and caliper; The adjustable clamp handle is positioned at fixing pincers handle; Afterbody at fixing pincers handle is equipped with a locking cap by screw thread, to prevent that the adjustable clamp handle from all being pulled out; As shown in Figure 2, be provided with a turn between the afterbody of fixing the pincers handle and locking cap, turn radially connects the adjustable clamp handle.

During use,, moving jaw is moved forward and backward in caliper by rotating adjusting nut, and the distance between change and the regular jaw, to satisfy the change of clamping diameter; Along with the axial pulling of adjustable clamp handle in fixing the pincers handle, produce frictional force between the outer wall of turn and adjustable clamp handle, and assurance adjustable clamp handle is located at any time automatically in fixing pincers handle; Simultaneously, locking cap and turn have stopped that effectively the oil stain and the silt that are bonded on the adjustable clamp handle are brought in the fixing pincers handle.

Claims (1)

1. Boost pipe tongs outside it is made up of moving jaw, caliper, adjusting nut, regular jaw, fixing pincers handle, adjustable clamp handle, is characterized in that being provided with a turn between the afterbody of described fixedly pincers handle and the locking cap, and turn radially clamps the adjustable clamp handle.
