Description

Cross-shaped screwdriver head structure

The present invention relates to a screwdriver head structure, and more particularly to a cross-shaped screwdriver head structure capable of improving structural strength.

According to the conventional screwdriver structure, the connector can be inserted into the connecting end of the hand tool or the power tool, thereby driving the screwdriver head to perform a screw locking operation on the screw. When the screwdriver head is driven to drive the screw, the screwdriver head is twisted. If the reaction structure is subjected to a reaction force, if the structure of the common hexagonal screwdriver head is not in a balanced or symmetrical state, stress concentration will be easily generated, and the screwdriver head will be deformed from the local part of the concentrated force, and if it is cracked and at the same time When the locking screw is operated, the screwdriver head will be broken or cut off. Therefore, the conventional hexagonal column-shaped screwdriver head has a lack of structural strength, and the common screwdriver head has a cross-head shape. The screwdriver head drives the screw of the meter head, and there is a problem that the contact area is too small and the tightness is not good. Therefore, the conventional cross-head screwdriver head is not suitable for the screw of the cross and the head of the meter at the same time, and the utility of the screwdriver is practical. Insufficient problem.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention lies in the above-mentioned existing technologies. Missing, providing a cross-shaped screwdriver head structure.

A sub-head is formed with a rod body and a head portion. The rod body has a hexagonal shape and a six-faceted surface and a hexagonal line. The head portion is formed at one end of the rod body, and the head portion is formed with a cross-tip shape. a four-wing piece, and the four wing pieces are provided with two oblique grooves and two oblique groove grooves in a diagonal shape, and the oblique cutting grooves are all opposite to the angular position of the rod body, and the oblique cutting grooves are For the position of the face of the rod body, the auxiliary head is protruded from the bottom of the inclined groove and the inclined groove, and the auxiliary strip extends from the tip end of the head toward the bottom end.

Wherein, the rod body is formed with an annular groove at the other end provided with the head.

The first main purpose of the present invention is that the rod body is provided with a six-faceted surface and a hexagonal line, and the head portion is formed with a four-piece piece in a cross-shaped shape, and the four-wing piece is concavely disposed between the four pieces. The oblique cut groove and the two oblique cut groove, and the oblique cut groove are all opposite to the angular position of the rod body, and the oblique cut groove is positively opposite to the face position of the rod body by the two oblique cut grooves The line and the two oblique grooves are opposite to the structure of the face, so that the bearing head has the same bearing capacity on the diagonal two wings, that is, the blade can be prevented from being damaged by the unilateral deformation, and the head is driven when the screw is driven. Because of the reaction force generated by the torsion, the reaction force can be uniformly distributed through the symmetry of the rod body and the head, thereby effectively improving the structural strength of the screwdriver head.

The second main purpose of the present invention is that the head is convexly provided with an auxiliary strip at the bottom of the oblique groove and the inclined groove, and the auxiliary strip extends from the tip end of the head toward the bottom end, and the screwdriver is extended. When the head is to drive the screw of the crosshead, the screwdriver head can be inserted and screwed only by the cross-shaped fins, and when the screwdriver head is to drive the screw of the meter head, the screwdriver head can cooperate with the auxiliary by the fins. The strip forms a plug and a screw lock, so that the screwdriver head has both a screw for driving the crosshead and the head of the meter, so as to improve its practicability.

Other objects, advantages and novel features of the present invention will become more apparent from the detailed description and the accompanying drawings.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [simplified description of the drawings] as follows: First, please continue from Figure 1 to Figure 8. A cross-shaped screwdriver head structure includes: a sub-head 10 formed with a rod body 11 and a head portion 12, the rod body 11 having a hexagonal shape and a hexagonal line 111 and a hexagonal line 112, and The head portion 12 is formed at one end of the rod body 11, and the rod body 11 is formed with an annular groove 113 at the other end of the head portion 12, and is formed through the annular groove 113 to form a quick connection with a driving tool (not shown). And the head 12 is formed in the shape of a cross. There are four wing pieces 121, and the four wing pieces 121 are concavely disposed with two oblique cutting grooves 122 and two oblique cutting grooves 123, and the oblique cutting grooves 122 are all facing the corner line 112 of the rod body 11. The position of the inclined groove 123 is positive for the position of the face 111 of the rod body 11, and the head portion 12 is convexly provided with an auxiliary strip 124 at the bottom of the inclined groove 122 and the inclined groove 123, and the auxiliary portion is provided. The strip 124 extends from the tip end of the head 12 toward the bottom end in a tapered manner.

The effect of the actual use is further illustrated in the first to eighth figures. The rod body 11 is provided with a six-faced surface 111 and a hexagonal line 112, and the head portion 12 is formed with a four-winged cross. a piece 121, and the four wing pieces 121 are concavely disposed with two oblique grooves 122 and two oblique grooves 123, and the oblique grooves 122 are all positioned at an angle 112 of the rod body 11, and The inclined grooves 123 are all facing the position of the face 111 of the rod body 11. The diagonal head 112 and the two oblique grooves 123 are opposite to the face 111, so that the bit 10 is in the pair. The two corner pieces 121 have the same bearing capacity, that is, the flank deformation damage can be prevented by the different resistance of the flap 121, and the reaction force of the head 12 due to the twist when the screw is driven can be transmitted through the rod. The body 11 and the head 12 are symmetrically formed to form a uniform distribution, thereby effectively improving the structural strength of the bit 10, and on the other hand, together with the figures 9 and 10, the head 12 is inclined and 122 obliquely An auxiliary strip 124 is protruded from the bottom of the slot of the slot 123, and the auxiliary strip 124 extends from the tip end of the head 12 toward the bottom end. 10 When the screw A of the crosshead is to be driven, the screwdriver head 10 can be inserted and screwed only by the cross-shaped flap 121, and can be matched with the screw A of the auxiliary strip 124 to increase the screwdriver head 10 and The contact area of the screw A makes the screw lock action more reliable and stable, and when the screwdriver head 10 is to drive the screw B of the meter head, the screwdriver head 10 can be inserted into the auxiliary strip 124 by the flap 121 to form a plug and a screw lock. It can also increase the contact area between the screwdriver head 10 and the screw A, thereby allowing the screwdriver head 10 to have the screw (A) (B) for driving the crosshead and the head of the meter, 俾 To improve its practicality.

In summary, this creation has indeed achieved a breakthrough structural design, and has improved new content, while at the same time achieving industrial use and progress, and this creation is not seen in any publication, but also novel, when In accordance with the provisions of the relevant laws and regulations of the Patent Law, a new type of patent application is filed according to law, and the examination authority of the bureau is required to grant legal patent rights.
