Abstract
The invention discloses a screwdriver which can tap the hole, belonging to the field of hardware tools. At present, screwdriver and screw tap are hardware which is often used in machining factory. However, problems such as strong pertinence of operation object and weak universality and single function exists in the prior hardware. The screwdriver aims to provide a screwdriver which has the function of screw tap by arranging screw tap cutting head 2 on the rotating rod 3 of the screwdriver to realize the goal of multifunction. To have better function, the rotating handle of the screwdriver is provided with a force applying device. The screwdriver has the advantages of rational design, simple structure and convenient use, thus being applicable to various machining places.
Description
Technical field
The invention belongs to the hardware ﹠ tools field, is a kind of screw rotating tool that can carry out tapping to the hole.
Background technology
At present, in machining factory, screw rotating tool and screw tap are two kinds of hardware ﹠ tools comparatively commonly used.Yet they all exist very strong and versatility is very poor, function of use the is single characteristics of the specific aim of operand.In order to save man-hour, when work, generally required various tool to be ready to, keeping has all brought certain trouble and miscellaneous instrument is for using still.
Summary of the invention
The purpose of this invention is to provide a kind of screw rotating tool, it is to have utilized screw rotating tool and screw tap all to have the characteristics of axial turn when operation, by on the swing arm 3 of screw rotating tool, being provided with screw tap cutting head 2, thereby make screw rotating tool have the function of screw tap simultaneously, reach the purpose that a tool is used more.In addition, be greater than the required torque of turn screw usually because carry out tapping needed torque of when operation, to be provided with augmentor on the tool be necessary so revolve at this.For finishing function better, also designing on the swing handle of screw rotating tool provided by the present invention has augmentor.Also promptly, screw rotating tool provided by the present invention both can directly be twisted with hand, also can twist with spanner or box spanner.
The invention has the beneficial effects as follows: the present invention integrates the function of screw rotating tool and two kinds of instruments of screw tap, has characteristics reasonable in design, simple in structure, easy to use, can be widely used in various machinings place.
Description of drawings
Fig. 1 is a structure chart of the present invention.Mark among Fig. 1 and corresponding name are called: 1. rotating tool head, 2. screw tap cutting head, 3. swing arm, 4. swing handle, 5. through hole.Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
As shown in Figure 1, the swing arm 3 of this screw rotating tool is provided with screw tap cutting head 2, and the outer diameter D 2 of its plug tap cutting head 2 should be greater than the maximum transverse size D1 of rotating tool head 1.Swing handle 4 cross sections of this screw rotating tool are hexagon, and on swing handle 4, offer one with the perpendicular through hole 5 of screw rotating tool central axis.So when carrying out the tapping operation, not only can increase the torque that this revolves tool, guarantee carrying out smoothly of tapping by using spanner.And, equally also can play the effect that increases torque by the bar-shaped object that in through hole 5, has inserted the effect of strand hand.In addition, above-mentioned two kinds can increase the device that revolves the tool torque and not only can use in tapping, when screw (or nut) when being lived or being twisted to such an extent that tightly be difficult to turn by rust, also can screw (or nut) be screwed out by augmentor.
