Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figure 1, a kind of Multifunctional pipe wrench screw wrench, including spanner handle 1, fixed plier 2 and movable plier 3, Gu Determine the upper end that plier 2 is fixed on spanner handle 1, movable plier 3 is L-type, and 2 are provided with sliding slot 2.1 on fixed plier, movable plier 3 Lower end has screw thread and is inserted into the sliding slot 2.1 of fixed plier 2, the threaded screw rod 3.1 of movable plier 3 and 4 phase of adjusting nut Mutually cooperation, adjusting nut 4 are located in a cavity 2.2 of fixed 2 lower end of plier；The inside of movable plier 3 is cast with pawl 3.2, Gu Determine that there is anti-skidding card 2.3 on the inside of plier 2, is provided with groove on anti-skidding card 2.3；1 section of spanner handle is ellipse, internal With cavity 1.1, screwdriver 5 is equipped in cavity, the screwdriver 5 includes driver bit 5.1 and screwdriver handle 5.2, the spiral shell Silk cutter head 5.1 is installed in screwdriver handle 5.2, and 5.2 bottom of screwdriver handle has external screw thread 5.3, and 1 bottom cavity of spanner handle has Internal screw thread 1.2,5.2 lower end of screwdriver handle are fixed with impact head 5.4, and screwdriver 5 is fixed on spanner handle 1 by internal and external threads cooperation Cavity in.

Further, movable 3 inside pawl 3.2 of plier is uniformly distributed in the vertical direction, extends in a lateral direction threaded Screw rod 3.1 a quarter at.

Further, movable plier 3 laterally move to fixed plier 2 it is nearest when the free gap with 5mm.

Further, the impact head 5.4 of 5.2 lower end of screwdriver handle is spherical shape, and outer end has anti-skid chequer 5.5.

For tightening or dismantle positive direction screw, live well in use, holding this spanner according to the Adjusting Shape of workpiece Dynamic plier 3, when tightening screw clockwise, movable plier 3 is on right side, and when disassembly screw counterclockwise, movable plier 3 is on a left side Side；If spanner takes anti-operated, screw can only be dismantled and screw can not be tightened.Tighten or dismantle opposite direction screw When, it is opposite with aforesaid operations.When threaded round steel or irony water pipe are installed, the movable plier 3 of spanner is adjusted to appropriate Position tightens after workpiece is installed in place clockwise, removes spanner, different due to being arranged on the inside of movable plier 3 and fixed plier 2 Anti-skid structure, movable plier use pawl structure, and fixed plier uses striped groove structure, therefore can lead to when clamping workpiece It crosses mutual cooperation and stings clamping of workpieces, even if there is stripped thread and are also possible to prevent to slip in screw or lead screw, movable plier and fixed plier There is the free gap 5mm in extreme position, therefore it is also very convenient to be detached from workpiece；Movable plier 3 prolongs in a lateral direction Stretching facilitates to grab resultant force to big workpiece at a quarter of threaded screw rod 3.1.If necessary to dismantle the nut of widget When bolt, screwdriver can be taken out by rotating percussion head counterclockwise, impact head is spherical shape, meets ergonomics；Screwdriver Head and screwdriver handle use dismountable structure, are convenient for changing driver bit of different shapes, the scope of application is wider.
