Description

A multifunctional screwdriver

technical field

The utility model relates to the field of hardware tools, in particular to a multifunctional screwdriver.

Background technique

A screwdriver is a tool used to turn a screw to force it into place, usually with a thin wedge-shaped head that fits into a slot or notch in the screw head. There are mainly two types: a word (negative sign) and a cross (positive sign). There are also hexagonal screwdrivers that are common, including inner hexagonal and outer hexagonal. In order to apply a small torque to the flat-blade screw, people thought of opening a slot on the screw head, and the screw can be tightened and loosened conveniently with the corresponding flat-blade screwdriver. However, with the rapid development of science and technology, screw The application of screwdrivers is becoming more and more extensive, and the shortcomings of screws and flat-head screwdrivers are also presented. First of all, once the slot of the screw head is damaged, the screw cannot be unscrewed. The longer the length of the slot, the easier it is to be damaged during the screwing process. In order to shorten the length of the notch, improve the ability of the notch to resist damage, and transmit the same amount of torsion, people thought of using a cross groove, which can withstand the same torsion, but the length of a notch is shortened by half. The ability has been greatly strengthened. The screwdriver is originally flat and cannot be used for cross-recessed screws. Only another type of cross-recessed screwdriver can be produced to correspond to cross-recessed screws. In this way, there are two kinds of screwdrivers. Later, according to the needs of production practice, screwdrivers with various blades appeared.
