Firstly, through the setting of the portion of buckling for play the effect of buffering, when electric screwdriver or pneumatic screwdriver screwed down the screw, because the effect of the portion of buckling for the perpendicular direction's power decomposes, thereby plays the buffering effect. Secondly, adopt the structure setting of platykurtic, it is more convenient to distort the processing, and for columniform distortion, the structure of platykurtic, the buffering effect is more obvious, and simultaneously, the setting of platykurtic unloads the power conduction and more accelerates.

Wherein the cross-sectional area of the twisted portion is smaller than that of the fixed portion.

The cross-sectional area of the twisting part is arranged, so that the overall stability is improved, and the processing is more convenient.

Wherein, the twisted part is provided with a twisted inclined plane, the included angle formed by the twisted inclined plane and the central shaft of the batch head is A, and A is more than or equal to 6 degrees and less than or equal to 20 degrees.

The twisted inclined plane angle of the twisted part is arranged, so that the force conduction in the normal use process is ensured, and the buffering effect is ensured.

Wherein the twisted portion is twisted clockwise.

The clockwise distortion is arranged, and the overall buffering effect is further improved.

Wherein, the junction of distortion portion and fixed part is equipped with the spigot surface.

The arrangement of the guide surface ensures the connection strength between the guide surface and ensures the buffering of the whole buffering force.

Wherein, the guide surface is an inclined surface.

The arrangement of the inclined plane further ensures the overall buffering effect.

Wherein, wear-resisting grooves are arranged on the head part and the fixing part.

The wear-resisting groove is arranged, so that the whole body is installed and used, the wear-resisting effect is improved, and slipping is prevented in the using process.

Wherein, the head, the connecting part, the fixing part and the twisting part are all coaxially arranged.

The arrangement of the concentric shafts enables the overall torsion to be more stable.

Wherein, the head part, the connecting part, the fixing part and the twisting part are integrally formed.

The integrated forming is adopted, so that the integral processing is more convenient, and the production cost is reduced.

Wherein, the material of batch head is alloy steel.

And the alloy steel is adopted, so that the overall strength is improved.

Detailed Description

Example 1:

referring to fig. 1-3, a batch head includes a head portion 1, a connecting portion 2, a fixing portion 3 and a twisting portion 4, the head portion 1 is connected and fixed with the fixing portion 3 through the connecting portion 2, the other end of the fixing portion 3 is connected with the twisting portion 4, the batch head can be a single-head batch head or a double-head batch head, only the structure of the double-head batch head is described in the present application, the single-head batch head is of a similar structure, and therefore, the details are not repeated herein.

The double-end is criticized the head and is included two heads 1, two connecting portion 2, two fixed part 3 and twist portion 4, and two fixed part 3 are connected through twist portion 4, and criticize the head and set up for the symmetry. Two heads 1, two connecting portions 2, two fixed portions 3 and the portion of buckling 4 are the coaxial setting, have guaranteed the stability of whole rotation.

Twist portion 4 is the platykurtic, and its cross section is the rectangle, and the cross sectional area of twist portion 4 is less than the cross sectional area of fixed part 3, through 4 stamping forming of twist portion earlier, then the heating twists for form twist portion 4, it should be noted here that, twist portion 4 can form a plurality of twists, form similar twist type twist, here preferably not exceed 360 twists, only one twist promptly, and the direction of twist is clockwise the twist, unanimously with the direction of rotation, can improve buffering effect. Specifically, the outer side of the twisting part 4 is provided with a twisting inclined plane, the included angle formed by the inclined plane and the central shaft of the batch head is A, A is more than or equal to 6 degrees and less than or equal to 20 degrees, and A is preferably 13 degrees. The joint of the twisting part 4 and the fixing part 3 is provided with a guide surface which is an inclined surface. The arrangement of the guide surface ensures the connection strength between the guide surface and ensures the buffering of the whole buffering force.

Fixed part 3 and head 1 are regular hexagon settings, and all are equipped with wear-resisting groove 11 on both sides, improve holistic stability, prevent to take place to skid in the use. The top end of the head part 1 is in a cross shape or a straight shape or a meter shape. In order to improve the matching between the top end and the screw, the top end of the head part 1 is provided with a round salient point 12 which can extend into the groove of the screw head part 1, so that the matching is more stable.

The connecting part 2 is provided with a notch 21, so that the connecting part is arranged in a concave manner, and the overall attractiveness and transmission efficiency are improved.

The head part 1, the connecting part 2, the fixing part 3 and the twisting part 4 are integrally formed, and the screwdriver head is made of alloy steel. Adopt alloy steel integrated into one piece's setting for it is more convenient that whole processing, reduction in production cost, simultaneously, makes holistic intensity improve.

Firstly, through the setting of the twisting part 4, the effect of buffering is achieved, and when the screw is tightened by the electric screwdriver or the pneumatic screwdriver, the force in the vertical direction is decomposed due to the effect of the twisting part 4, so that the effect of buffering is achieved. Secondly, adopt the structure setting of platykurtic, it is more convenient to distort the processing, and for columniform distortion, the structure of platykurtic, the buffering effect is more obvious, and simultaneously, the setting of platykurtic unloads the power conduction and more accelerates.
