Abstract
A kind of multi-functional, to object clamping easily, the firm instrument of turning round of pulling, it is that the modular construction of existing pipe vice and adjustable wrench has been done thorough improvement.It pulls hook by V-arrangement, and circular arc head tommy bar and cylindrical pin are formed.Pulling hook because of V-arrangement can freely rotate around bearing pin, thus to the object of different profiles and different big or small thicknesses automatically firm the pulling of clamping turn round.
Description
The present invention relates to a kind of instrument of turning round circle, many prismatics and irregular contour object of pulling.
Existing, known pulling turned round the instrument pipe vice and adjustable wrench is by the handle spanner, Flexible spanner is chewed with adjustable screw and is formed, their use all is to rotate earlier spiral to promote Flexible spanner and chew opening and become big or small shape just can pull to turn round object, pull when turning round big or small thickness object and also will regulate the size that Flexible spanner is chewed opening repeatedly, bother very much, and pipe vice can only be pulled and turns round circular object, adjustable wrench can only be pulled and turn round two opposed objects in plane, they do not have a holding function to object is actual, turn round but rely on self so-called size openings that object is pulled along the edge tangent line, therefore trackslip when being pulled the object of turning round.
The purpose of this invention is to provide one and pull the instrument of turning round, it is not only pulled and turns round circular object, can pull again and turn round many prismatics and irregular contour object, reaches the object clamping of being turned round pulling easily, the firm purpose of turning round of pulling.
The object of the present invention is achieved like this: designed an internal orifice drift angle 30 °-90 ° and often got 60 ° of inwalls and have the V-arrangement of the contrary sawtooth tooth of system and pull and collude, oppose and pulled two bites turning round object, with one also have movable circular arc head, the cover of the contrary sawtooth tooth of system to be clipped in and can clamping V shape to pull the tommy bar head that colludes, oppose and pulled the 3rd bite of turning round object, become triangle clamping shape, the running fix of movable circular arc head is controlled by alignment pin, is assemblied in one by cylindrical pin after tommy bar clamping V shape is pulled and colluded and becomes the present invention to pull the instrument of turning round.V-arrangement is pulled and is colluded and can freely rotate around bearing pin, turns to any angle and all becomes triangle clamping shape with the movable circular arc head of tommy bar head, and any object all is subjected to three extruding at this.Therefore to size, thickness, circle, many prismatics and the clamping automatically of irregular contour object, firm pulling turned round.
The present invention is further described below in conjunction with accompanying drawing:
Among the figure, 1, there is the tommy bar pulled of folder in generation; 2, cylindrical pin; 3, V-arrangement is pulled and is colluded; 4, alignment pin; 5, movable circular arc head.
In the drawings, the folder above the tommy bar (1) is pulled clamping V shape and is pulled and collude (3) and be assembled into one by cylindrical pin (2), and the tommy bar head also is with movable circular arc head (5), and movable circular arc head (5) running fix is controlled by alignment pin (4).
Claims (1)
- A kind of wrench, by V-arrangement pull collude, garden arc head tommy bar and garden axis pin of column form, V-arrangement is pulled and is colluded mouthful inwall and tommy bar garden ogive all has the contrary sawtooth tooth of system.
