If we talk about the most simple embodiments of the device, it is a monolithic core, which has a sting, and it ends with a handle with a large heel. Something similar happened in the course of in the days of the Soviet Union.
In our time, product design takes the form of the hexagon near the tip or on the handle. Due to this it is possible to transmit rotary motion. To deal successfully moved, a screwdriver is necessary to work for a couple. One person holds the screwdriver and gradually cranking it, and the second beats hammer handle instrument.
Of course, not do without the negative aspects. They are as follows:
- To work need two people.
- No conversion of the transmitted energy into rotational force. Causing the hammer blows, we only repel rust. Improved product combines and impacts and rotation.
For the most part "shock screwdriver" it is called an upgraded model, simple options have long been relegated to the past and not used.
Modern model has inside handle shock-rotary structure fixed on the pinion instrument sting. The handle is a clip that has a reciprocal teeth. hammer blow causes the clip to move at the same time as the sting is driven.
As a result, under the influence of mechanical force screwdriver hammer rotated by a few degrees. It seems little, but more than enough to snap fasteners weakened and made possible the further work with conventional tools. In the future, the spring clip is automatically returned to its former state.
Use the tool is very simple. Due to the mechanism of rotation is provided by a complex rotational and translational actions in the slot, making it easy to unscrew that simple methods do not remove.
Features and variations of the shock screwdrivers
This product has another name - namely, power screwdriver. Most often it is used in plumbing works. Product Feature - reinforced handle.
As is clear, the main difference from the conventional similar devices analogs - a body made of metal, wherein a particular strength. Because of this, and the size, of course, greater than that of a conventional screwdriver.
There are technical differences:
- There is a ratchet gear. Current models are not only able to twist, but also spinning.
- Features handle. Pen device - is not something that an ordinary pen screwdriver is the housing products, without which the work would be virtually impossible.
-
Material. The basic material for the housing - steel. Sometimes over the polyurethane coated steel, and rubber.
The device is used not only as a household device - quite successfully, it shows itself in a production environment. Often it is used in the workshop.
Reference. Modern power screwdriver, you can not just unscrew the rusted fasteners, but also to tighten it.
Separately to say about the possibility of changing tips. Almost all of the kits that are commercially available, equipped with interchangeable bits, a minimal supply of this size eight and ten millimeters. Typically, the kit includes a screwdriver and various bits to four - both flat and curved. It is very convenient, because the twist is necessary to mount different.
Can be used as a normal screwdriver, not necessarily permanently on it to strike.
As already noted, there is not much reason to buy only one screwdriver. Very often it is necessary to change the tool to the other. That is why the sale of these kits began to appear.
In addition to nozzles designed for unscrewing fastener can be supplied complete nozzle-equipped drill bits. Sometimes it is very convenient, as there is no need to go for the sake of only one drill hole.
More modern sets are not only flat and curly heads, but also different hexagons. The main thing - to look carefully not only on the number of interchangeable bits, but also the quality of the material from which everything is made. After all nozzles must withstand impact.
