Embodiment Construction

[0006] As shown in FIG. 1 , a tap cutting head 2 is provided on the shaft 3 of the screwdriver, wherein the outer diameter D2 of the tap cutting head 2 should be larger than the maximum lateral dimension D1 of the screwdriver head 1 . The handle 4 of the screwdriver has a hexagonal cross section, and a through hole 5 perpendicular to the central axis of the screwdriver is opened on the handle 4 . Therefore, when performing a tapping operation, not only can the torque of the screwdriver be increased by using a wrench, but also the smooth progress of tapping can be ensured. Moreover, the effect of increasing the torque can also be achieved by inserting a rod-shaped object that acts as a hand twister into the through hole 5 . In addition, the above two devices that can increase the torque of the screwdriver can not only be used when tapping, but also can be used when the screw (or nut) is difficult to twist due to being rusted or tightened. The force device unscrews the screw (o...

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 [0001] The invention belongs to the field of hardware tools, and relates to a screwdriver capable of tapping holes. Background technique [0002] At present, in machining factories, screwdrivers and taps are two commonly used hardware tools. However, they all have the characteristics that the operation object is very specific, but the versatility is poor, and the use function is single. In order to save working hours, it is generally necessary to prepare all kinds of tools required during work, and a wide variety of tools have brought certain troubles for both use and storage. Contents of the invention [0003] The purpose of this invention is to provide a kind of screwdriver, it is to have utilized screwdriver and screw tap to have the characteristic of axial rotation during operation, by being provided with tap cutting head 2 on the screw rod 3 of screwdriver, Therefore, the screwdriver has the function of a screw tap at the same time, achieving the pur...
