Problems solved by technology
[0002] At present, small-sized thread processing tools mainly include taps and dies. Taps are used to process small-sized internal threads, and dies are used to process small-sized external threads. The auxiliary tool for clamping taps for internal thread processing is tap wrench, also known as "Hinge bar", the auxiliary tool used to clamp the die for external bolt processing is the die wrench, also known as the "die holder", and the tap wrench and the die wrench are always two independent wrenches, that is, when needed When carrying taps and dies for thread processing at the same time, it is also necessary to carry tap wrench and die wrench at the same time, which increases the carrying capacity of auxiliary tools invisibly, and for tool manufacturers, it will inevitably increase auxiliary tools. manufacturing cost
[0003] Furthermore, when the small-sized threaded holes on the workpiece are processed, it is usually necessary to tighten the bolts. At this time, the auxiliary tool of the screwdriver must be indispensable. That is to say, while carrying the tap wrench and the die wrench , it is also necessary to carry a screwdriver, which leads to a further increase in the carrying capacity of auxiliary tools. Not only will it occupy limited tool storage space, but the self-weight of a large number of auxiliary tools will also reduce the convenience of carrying
[0004] In addition, when the traditional tap wrench is used to hold the tap for internal thread processing, and when the traditional die wrench is used to hold the die for external bolt processing, the tap or die will often be damaged due to improper force, especially when the tap is used to process blind hole threads. Be especially careful, because it is very easy to break the tap when processing blind hole threads, and at the same time cause the part to be scrapped
