Abstract
The invention discloses an impact deformation resistant screwdriver bit. The impact deformation resistant screwdriver bit comprises bit parts for operating a screw, and a connecting part in fastening connection with a clamping tool, wherein the bit parts are respectively located on end parts of the connecting part; a section of anti-twist part is formed on the middle section of the connecting part, and is in a twisted state along the axis direction of the screwdriver bit. According to the impact deformation resistant screwdriver bit, the anti-twist part in the twisted state is arranged on the connecting part of the screwdriver bit, and when in use, the twisting force borne by the screwdriver bit is opposite to the twisting direction of the anti-twist part, so that the anti-twist part can relieve the torsion deformation of the screwdriver bit, and the service life of the screwdriver bit is effectively prolonged.
Description
Technical field
The present invention relates to a kind of screwdriver head, particularly the shock-resistant distortion screwdriver head of one.
Background technology
Common screwdriver head connecting portion is all straight cylinder, when screwdriver head operationally, bear huge torsion, screwdriver head is under huge twisting force, and be usually distorted distortion, and serious even twists off, cannot continue use.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of shock-resistant distortion screwdriver head, this shock-resistant distortion screwdriver head, can bear larger torsion, can alleviate deformed damaged.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of shock-resistant distortion screwdriver head, comprise the head for operating screw and the connecting portion that can be connected with clamping device stop, described head lays respectively at the end of connecting portion, described connecting portion interlude is formed with one section of anti-twisting portion, this anti-twisting portion is twisted state along screwdriver head axis direction.
As a further improvement on the present invention, described connecting portion is hexagonal structure.
As a further improvement on the present invention, described anti-twisting portion diameter is less than connecting portion two ends diameter.
As a further improvement on the present invention, the radial cross-section in described anti-twisting portion is non-circular structure.
As a further improvement on the present invention, triangular in shape, square, the hexagon of described anti-twisting portion radial cross-section, star, spline shape, bilateral lack the one in circle.
As a further improvement on the present invention, described connecting portion two ends are respectively equipped with a head.
As a further improvement on the present invention, described head is connected by a shock-resistant portion with between connecting portion, and this shock-resistant portion is the mid diameter bus that is less than two ends diameter is the cylinder of circular arc line.
The invention has the beneficial effects as follows: the present invention by arranging the anti-twisting portion in twisted state on screwdriver head connecting portion, in use, the torsion that screwdriver head bears is contrary with this anti-twisting portion direction of twist, make this anti-twisting portion alleviate screwdriver head to be out of shape by torsion, effectively extend the service life of screwdriver head.
Accompanying drawing explanation
Fig. 1 is structural perspective of the present invention;
Fig. 2 is structural front view of the present invention;
Fig. 3 is a kind of anti-twisting cross section schematic shapes of the present invention.
Detailed description of the invention
Embodiment: a kind of shock-resistant distortion screwdriver head, comprise the head 1 for operating screw and the connecting portion 2 that can be connected with clamping device stop, described head 1 lays respectively at the end of connecting portion 2, described connecting portion 2 interlude is formed with one section of anti-twisting portion 3, this anti-twisting portion 3 is twisted state along screwdriver head axis direction, during use, keep screwdriver head direction of rotation contrary with anti-twisting portion 3 direction of twist, the torsion that screwdriver head transmits can be absorbed like this, alleviate screwdriver head be out of shape by torsion, avoid screwdriver head by torsion be distorted be out of shape and damage.
Described connecting portion 2 is hexagonal structure.
Described anti-twisting portion 3 diameter is less than connecting portion 2 two ends diameter.
The radial cross-section in described anti-twisting portion 3 is non-circular structure.
Described anti-twisting portion 3 radial cross-section is triangular in shape, square, hexagon, star, spline shape, bilateral lack one in circle.
Described connecting portion 2 two ends are respectively equipped with a head 1, form double elevator head.
Described head 1 is connected by a shock-resistant portion 4 with between connecting portion 2, and this shock-resistant portion 4 is less than two ends diameter bus in mid diameter is the cylinder of circular arc line, improves screwdriver head impact resistance performance.
