Description
Technical field
The utility model relates to a kind of hand tools, specifically a kind of Boost pipe tongs.
Background technology
Pipe wrench has brought very big convenience for installation and removal work as a kind of instrument.Common pipe wrench is made up of moving jaw, pincers handle body, adjusting nut, moving jaw is contained in the sleeve pipe of pincers handle body by adjusting nut, rotate adjusting nut, moving jaw can move forward and backward along pincers handle body, adjust jaw size with this, the length of pipe wrench pincers handle is fixed mostly, then needs to change pincers handle longer pipe pincers for the disassemble and assemble work of the big moment of needs, or pipe of suit increases the length of the arm of force on existing pipe wrench pincers handle.
Present Boost pipe tongs is that the pincers handle adopts sleeve type structure mostly, is made up of sleeve pipe and afterburning pull bar, and afterburning pull bar can stretch in sleeve pipe, establishes the stifled ring in a location at the sleeve pipe tail end, is provided with a jump ring in the stifled ring in location, and jump ring radially clamps afterburning pull bar.Afterburning pull bar can only be when a regular length position clamped blocking be circular pipe fitting because sleeve pipe and afterburning pull bar adopt, afterburning pull bar rotates in sleeve pipe easily, thereby can influence the reliability and the security of its work, the scope of application is restricted.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure in order to overcome the deficiency of above-mentioned technology, and cost is low, and easily make, assembling, Boost pipe tongs flexible and convenient to use.
The utility model solves the scheme that its technical problem takes: a kind of Boost pipe tongs, comprise moving jaw, regular jaw, pincers handle body, adjusting nut, it is characterized in that the cylinder that clamps handle body afterbody is provided with external screw thread, the termination is provided with rectangular recess, one end of reference column is rectangular to be entered in the groove, the force application handle two ends are provided with external screw thread, in be provided with flexible force application handle, reference column is fixed in the end of flexible force application handle, the afterbody of flexible force application handle is provided with handle, fixed cover on the flexible force application handle is connected with force application handle, the end of force application handle is provided with outside tapered pad in fixed cover, be provided with taper surface in the fixed cover, force application handle is fixedlyed connected with the cylinder of pincers handle body afterbody by adapter sleeve.Rotation its inner conical face of fixed cover and taper pad break away from, and can adjust flexible force application handle, the length that realization needs, and the rotation fixed cover makes tight contact of its inner conical face and taper pad can fix flexible force application handle.
Taper pad in the fixed cover of the present utility model is two lobe types.
The utility model is simple and reasonable for structure, and is easy to manufacture, easy to use, flexibly flexible, and force application handle is fixed on the pincers handle body by adapter sleeve, and the taper surface in the fixed cover contacts with the taper pad and tightens fixed cover, can reach self-locking, realizes the locking of flexible force application handle.Can make between flexible force application handle and the force application handle fixing on any relative position by the taper surface effect in the fixed cover, because reference column is fixed on flexible force application handle end, handle can not rotate in the use operating process, has increased user's comfort, has increased the pipe wrench integral intensity simultaneously.
Description of drawings
The utility model is described in detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Mark among the figure: 1, moving jaw, 2, regular jaw, 3, pincers handle body, 4, adjusting nut, 5, reference column, 6, adapter sleeve, 7, force application handle, 8, flexible force application handle, 9, fixed cover, 10, the taper pad, 11, handle.
The specific embodiment
By shown in Figure 1: a kind of Boost pipe tongs, comprise moving jaw 1, regular jaw 2, pincers handle body 3, adjusting nut 4, on the cylinder of pincers handle body 3 afterbodys, be provided with external screw thread, the termination is provided with rectangular recess, one end of reference column 5 is rectangular to be entered in the groove, force application handle 7 two ends are provided with external screw thread, in be provided with flexible force application handle 8, reference column 5 is fixed in the end of flexible force application handle 8, the afterbody of flexible force application handle 8 is provided with handle 11, fixed cover 9 on the flexible force application handle 8 is connected with force application handle 7, the end of force application handle 7 is provided with outside tapered pad 10 in fixed cover 9, taper pad 10 is two lobe types, is provided with taper surface in the fixed cover 9, and force application handle 7 is fixedlyed connected with the cylinder of pincers handle body 3 afterbodys by adapter sleeve 6.Rotation its inner conical face of fixed cover and taper pad break away from, and can adjust flexible force application handle, the length that realization needs, and the rotation fixed cover makes tight contact of its inner conical face and taper pad can fix flexible force application handle.
During use, rotation fixed cover 9 breaks away from its inner conical face and taper pad 10, can adjust flexible force application handle 8, because reference column 5 is fixed in the end of flexible force application handle 8, can locate to move and carry out the flexible force application handle 8 of push-and-pull, the length that realization needs, at rotation fixed cover 9 its inner conical face is closely contacted with taper pad 10, the taper pad 10 of two lobe types moves forward with fixed cover 9, when the front end face of taper pad 10 contacts with the end face of force application handle 7, taper pad 10 can not move forward again, continues to tighten fixed cover 9, and this moment, the taper surface of fixed cover 9 exerted pressure for taper pad 10, make two lobe type taper pads, 10 internal diameters tightly embrace flexible force application handle 8, produce the self-locking effect, give fixed cover 9 application of forces big more, the self-locking effect is obvious more.The anti-fixed cover 9 of turning round, fixed cover 9 inner conical faces and two lobe type taper pads 10 break away from, and the gap appears in two lobe type taper pad 10 internal diameters and flexible force application handle 8, can adjust the flexible force application handle 8 of push-and-pull and move in force application handle 7, realizes the arm of force of required pipe wrench.
