Abstract

The invention discloses a novel structure of a screwdriver bit. The novel structure comprises a connecting part, an impact resistance part and a head from one end to the other end, wherein the connecting part is connected with an electric screwdriver, the head is used for operating a screw, and the radial cross section of the impact resistance part is of non-circular structure. The novel structure has the advantages that impact resistance is greatly improved, the novel structure cannot deform or break when impacted by great force and can bear great torque without deformation, and service life of the novel structure is effectively prolonged.

Description

Screwdriver head new construction
Technical field
The present invention relates to a kind of screwdriver head, particularly a kind of screwdriver head new construction.
Background technology
Shock-resistant portion bus between common screwdriver head connecting portion and head is the high circular arc lines in middle low both sides, its radial cross-section is all rounded, this kind of structure due to shock-resistant portion mid diameter suddenly little, and its cross section is circular, its intensity is low, impact resistance is poor, in use runs into large impulsive force and torsion and is easy to deform and even fractures, cause screwdriver head to be scrapped and cannot continue to use.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of screwdriver head new construction, this screwdriver head new construction resistance to impact is strong, can bear larger torsion, not fragile.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of screwdriver head new construction, comprise the connecting portion for being connected with electric screw driver, shock-resistant portion and the head for operating screw from one end successively to the other end, the radial cross-section in described shock-resistant portion is non-circular structure.
As a further improvement on the present invention, described shock-resistant portion connecting portion adjacent with it and head diametrically inner shrinking structure relatively.
As a further improvement on the present invention, described shock-resistant portion is vertical cyclindrical shape structure.
As a further improvement on the present invention, described shock-resistant portion is connected with connecting portion and head transition along the two ends of screwdriver head length direction by taper surface.
As a further improvement on the present invention, triangular in shape, square, the hexagon of described shock-resistant portion radial cross-section, star, spline shape, bilateral lack the one in circle.
The invention has the beneficial effects as follows: the present invention is by being designed to non-circular structure by shock-resistant portion radial cross-section, substantially increasing its resistance to impact, when being subject to impacting energetically, also can not be out of shape or fracture, and its can to bear huge torsion indeformable, effectively extend its service life.

Detailed description of the invention
Embodiment: a kind of screwdriver head new construction, connecting portion 1 for being connected with electric screw driver, shock-resistant portion 2 and the head 3 for operating screw is comprised successively to the other end from one end, the radial cross-section in described shock-resistant portion 2 is non-circular structure, shock-resistant portion 2 radial cross-section is designed to the impact resistance that non-circular structure adds screwdriver head entirety, avoid its be in use subject to large impulsive force deform damage even fracture, enable screwdriver head bear the indeformable damage of larger torsion.
Described shock-resistant portion 2 is connecting portion 1 adjacent with it and head diametrically inner shrinking structure relatively.
Described shock-resistant portion 2, in vertical cyclindrical shape structure, strengthens screwdriver head bulk strength, avoids being subject to large impact power and fractureing.
Described shock-resistant portion 2 is connected with connecting portion 1 and head transition along the two ends of screwdriver head length direction by taper surface, by the conical surface, shock-resistant portion 2 is connected with connecting portion 1 and head transition, avoid screwdriver head connecting portion 1 stress to concentrate, ensure screwdriver head in use not frangibility.
Described shock-resistant portion 2 radial cross-section is triangular in shape, square, hexagon, star, spline shape, bilateral lack one in circle.
