Description
Technical field
The utility model relates to a kind of technical field of hand-operated tools, specifically a kind of locking pliers.
Background technology
Existing locking pliers by regular jaw, moving jaw, fixed handle, flexible handle, support plate, lift sheet, extension spring, set screw, rivet and form, during use, the retaining mechanism clamping work pieces of holding with a firm grip is opened retaining mechanism and is unclamped workpiece.After moving jaw was opened, the opening amount was less, can not big object of clamping, as: pipe fitting, joint etc.Existing locking pliers can only the clamping diameter smaller or equal to the pipe fitting of 40mm, have certain defective, the scope of application is restricted.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, reasonable in design, and low cost of manufacture is easy to use, can clamping less than the locking pliers of 55mm object.
The utility model solves the scheme that its technical problem takes: a kind of locking pliers, include regular jaw, moving jaw, fixed handle, flexible handle, lift sheet, support plate, set screw, extension spring, rivet, moving jaw is connected with the fixed handle front portion by rivet, the rear end of fixed handle is provided with set screw, be provided with extension spring between the middle part of fixed handle and the moving jaw, the flexible handle front end is fixedlyed connected with moving jaw by rivet, propping up front edge of board is connected with flexible handle by rivet, lifting sheet is connected with flexible handle by rivet, it is characterized in that being distributed with 27 profiles of tooth at regular jaw, 1-11 profiles of tooth are becoming with horizontal linear on 10 ° the oblique line, the angle of each profile of tooth is 102.7 °, 12-27 profiles of tooth with the tangent radius of oblique line be on the circular arc of 75mm, the angle of its profile of tooth is respectively 103.7 ° and 100.1 °, be distributions separately, be distributed with 25 profiles of tooth at moving jaw, 1-11 profiles of tooth are on the circular arc of 25mm at radius, each profile of tooth angle is 99.5 °, 12-25 profiles of tooth are on the circular arc of 75mm at radius, radius is that circular arc and the radius of 75mm is that the 25mm circular arc is tangent, the 12nd profile of tooth angle is 103 °, the 13rd, 14 profile of tooth angles are respectively 100.1 °, and 15-25 profile of tooth angles are respectively 103.7 °.
Regular jaw of the present utility model, moving jaw flute profile are reasonable in design, the opening amount increases, energy clamping diameter 55mm pipe fitting or joint, and skidding can not appear, have locking function, thus, not only possess the function of common locking pliers, and possess the function of pipe wrench and eagle's beak pliers, the installation that is used for pipe fitting joint is time saving and energy saving, easy to use, applied range.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark among the figure: 1, regular jaw, 2, moving jaw, 3, rivet, 4, extension spring, 5, support plate, 6, flexible handle, 7, lift sheet, 8, fixed handle, 9, set screw.
The specific embodiment
As shown in Figure 1: a kind of locking pliers, include regular jaw 1, moving jaw 2, fixed handle 8, flexible handle 6, lift sheet 7, support plate 5, set screw 9, extension spring 4, rivet 3, regular jaw 1 welds together with fixed handle 8, moving jaw 2 is connected with fixed handle 8 front portions by rivet 3, the rear end of fixed handle 8 is provided with set screw 9, be provided with extension spring 4 between the middle part of fixed handle 8 and the moving jaw, flexible handle 6 front ends are fixedlyed connected with moving jaw 2 by rivet, support plate 5 front ends are connected with flexible handle 6 by rivet, lifting sheet 7 is connected with flexible handle 6 by rivet, be distributed with 27 profiles of tooth at regular jaw 1,1-11 profiles of tooth are becoming with horizontal linear on 10 ° the oblique line, the angle of each profile of tooth is 102.7 °, 12-27 profiles of tooth with the tangent radius of oblique line be on the circular arc of 75mm, the angle of its profile of tooth is respectively 103.7 ° and 100.1 °, be distributions separately, namely 12 profile of tooth angles are 103.7 °, 13 profile of tooth angles are 100.1 °, 14 profile of tooth angles are 103.7 °, 15 profile of tooth angles are 100.1 °, and the like.Be distributed with 25 profiles of tooth at moving jaw 2,1-11 profiles of tooth are on the circular arc of 25mm at radius, each profile of tooth angle is 99.5 °, 12-25 profiles of tooth are on the circular arc of 75mm at radius, radius is that circular arc and the radius of 75mm is that the 25mm circular arc is tangent, the 12nd profile of tooth angle is 103 °, and the 13rd, 14 profile of tooth angles are respectively 100.1 °, and 15-25 profile of tooth angles are respectively 103.7 °.
During use, by flexible handle 6 with lift sheet 7 and support plate 5 constitutes locking mechanism, promote to lift sheet, retaining mechanism is opened, regular jaw 1 and moving jaw 2 open, and unclamp workpiece; The flexible handle of holding with a firm grip, the flat board that lifts the sheet front end is connected with the projection of support plate centre, regular jaw and moving jaw clamping work pieces are adjusted the rear end set screw 9 of fixed handle 8, can change the size of regular jaw 1 and moving jaw 2 opening amounts, regular jaw of the present utility model, moving jaw flute profile are reasonable in design, the opening amount increases, and clamping diameter 55mm skidding can not occur with interior pipe fitting or pipe joint, has locking function, easy to operate, high efficiency.
