Brief description of the drawings
By reading the detailed description made with reference to the following drawings to non-limiting example, the utility model and its spy
Sign, profile and advantage will become more apparent.The identical mark instruction identical part in whole accompanying drawings.Can be by
Accompanying drawing is drawn according to ratio, it is preferred that emphasis is purport of the present utility model is shown.
Fig. 1 is the structural representation of the utility model Multifunctional extrusion screw tap.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, but not as this practicality
New restriction.
Have, as shown in figure 1, the utility model Multifunctional extrusion screw tap structure includes：
Tap handle 1, in the utility model embodiment, the head end of tap handle 1 is provided with wire cone 2, tap handle 1
Tail end is provided with locking neck 4, and locking neck 4 is arranged with fixed square toes 5；The utility model is provided with the tail end of tap handle 1
Locking neck, process of manufacture plug tap are not easy to loosen, and machining accuracy is high, and service life is grown.
Further, one first is provided through by fixed square toes 5 to the axis center in the head end direction of tap handle 1 to lead to
Hole 6.
Some groups of screw-tap threadeds 3 are provided with wire cone 2, screw tap groove 9, and position are provided between some groups of screw-tap threadeds 3
Second through hole 7 is provided with wire cone 2, in embodiment of the present utility model, the second through hole 7 and the phase of first through hole 6
It is intercommunicated, and the aperture of first through hole 6 is greater than the aperture of the second through hole 7；Some branch's through holes are additionally provided with second through hole 7
8, those branch's through holes 8 are located at the both sides of the second through hole 7 and are interspersed and extend in screw tap groove 9；In reality of the present utility model
Apply in example, high-performance screw tap is injected since fixed square toes by first through hole at work, by the coolant for having pressure, and second is logical
Flow out in hole；Because the aperture of first through hole is greater than the aperture of the second through hole, so the hydraulic pressure that coolant is made by the outflow of the second through hole
Become big, and screw tap groove is flowed into by branch's through hole and realizes that the reinforcing to screw tap groove, screw-tap threaded and wire cone cools down, protect simultaneously
Lubrication is held, therefore can fully avoid high temperature can be to negative effect caused by screw tap due to cooling down.
