Description

When disassembling tractors, you often have to turn away hardened and stiff screws. Many troubles cause repairmen screws to attach the poles of generators and starters. Coping with them with a regular screwdriver is very difficult, and sometimes impossible. In cases where it is not possible to remove the screw in the usual way, you can try to use a hammer at the same time, except for a screwdriver. In this case, you need to insert the screwdriver blade into the screw spline and, tapping the screwdriver slightly with a hammer on the screwdriver handle, pull the screwdriver out of place with jerks (in tact). After that, usually further screwing will not present a difficulty. If the screw or screw cannot be removed by this technique, then the proposed screwdriver should be used. Post, guide and grip are secured on base by welding. Spring is installed between post and stop fixed on screwdriver. To increase the torque transmitted to the screwdriver, its handle is made with a wrench. In cases where it is not possible to hold the screws by hand, a grip is used. The screwdriver is designed to support the screw directly on the blade. The grip holds the screw and the spring presses the screwdriver blade against the slot in the screw head.
