Abstract
Screwdriver head is deformed the invention discloses a kind of impact resistance, including the connecting portion for operating the head of screw and can be connected with clamping device stop, the head is located at the end of connecting portion respectively, one section of anti-twisting portion is formed with the connecting portion interlude, the anti-twisting portion is in twisted state along screwdriver head axis direction, the present invention on screwdriver head connecting portion by setting the anti-twisting portion in twisted state, when in use, the torsion that screwdriver head is born is opposite with the anti-twisting portion direction of twist, make the anti-twisting portion alleviate screwdriver head to be deformed by torsion, effectively extend the service life of screwdriver head.
Description
Technical field
The present invention relates to a kind of screwdriver head, more particularly to a kind of impact resistance deformation screwdriver head.
Background technology
Common screwdriver head connecting portion is all straight cylinder, when screwdriver head operationally, bear huge torsion, screwdriver head
Under huge twisting force, it occur frequently that torsional deformation, serious even twists off, it is impossible to be continuing with.
The content of the invention
It is not enough in order to make up the above, screwdriver head is deformed the invention provides a kind of impact resistance, the impact resistance deforms screwdriver head,
Larger torsion can be born, deformed damaged can be alleviated.
The technical scheme that is used to solve its technical problem of the present invention is：A kind of impact resistance deforms screwdriver head, including
For the connecting portion that operates the head of screw and can be connected with clamping device stop, the head is located at the end of connecting portion respectively
One section of anti-twisting portion is formed with portion, the connecting portion interlude, the anti-twisting portion is in twisted state along screwdriver head axis direction.
As a further improvement on the present invention, the connecting portion is hexagonal structure.
As a further improvement on the present invention, 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 the anti-twisting portion is non-circular structure.
As a further improvement on the present invention, anti-twisting portion radial cross-section is triangular in shape, square, hexagon, star
Shape, spline shape, bilateral lack one kind in circle.
As a further improvement on the present invention, the connecting portion two ends are respectively equipped with a head.
As a further improvement on the present invention, connected between the head and connecting portion by an impact resistance portion, the resistance to punching
Hit portion and be less than cylinder of the bus of two ends diameter for circular arc line in mid diameter.
The beneficial effects of the invention are as follows：The present invention on screwdriver head connecting portion by setting the anti-twisting in twisted state
Portion, when in use, torsion that screwdriver head is born with the anti-twisting portion direction of twist on the contrary, make the anti-twisting portion alleviate screwdriver head by
Torsion is deformed, and effectively extends the service life of screwdriver head.
Brief description of the drawings
Fig. 1 is structural perspective of the invention；
Fig. 2 is structural front view of the invention；
Fig. 3 is a kind of anti-twisting cross section schematic shapes of the invention.
Embodiment
Embodiment：A kind of impact resistance deforms screwdriver head, including for operating the head 1 of screw and can stop with clamping device
The connecting portion 2 of dynamic connection, the head 1 is located on the end of connecting portion 2, the interlude of connecting portion 2 respectively is formed with one section
Anti-twisting portion 3, the anti-twisting portion 3 is in twisted state along screwdriver head axis direction, in use, keeping screwdriver head direction of rotation with preventing
The direction of twist of twist part 3 is on the contrary, can so absorb the torsion of screwdriver head transmission, and alleviation screwdriver head is deformed by torsion, it is to avoid risen
Subheader is distorted by torsion to be deformed and damages.
The connecting portion 2 is hexagonal structure.
The diameter of anti-twisting portion 3 is less than the two ends diameter of connecting portion 2.
The radial cross-section in the anti-twisting portion 3 is non-circular structure.
The radial cross-section of anti-twisting portion 3 is triangular in shape, square, hexagon, star, spline shape, bilateral lack it is circular in
One kind.
The two ends of connecting portion 2 are respectively equipped with a head 1, form double elevator head.
Connected between the head 1 and connecting portion 2 by an impact resistance portion 4, the impact resistance portion 4 is less than two in mid diameter
The bus for holding diameter is the cylinder of circular arc line, improves screwdriver head impact resistance performance.
Claims (5)
