Specific embodiment
It now will only be example but the non-specific embodiment to limit, and referring to appended diagram with regard to preferred construction of the invention
Description of contents is as follows:
Fig. 2 to Fig. 4 shows the screw 20 of one embodiment of the invention, and the screw 20 is including a body of rod 22 and is formed in the body of rod
One head 24 of 22 upper ends.The body of rod 22 is equipped with screw thread (being not shown on figure), and the top surface 26 on the head 24 has a groove 28
Combination sword to provide a tool (such as screwdriver head) is inserted into drive the screw 20 to rotate.The groove 28 includes a center
Area 30 from several external zones 32 that the center 30 extends radially outward and is connected between several external zones 32
Several connection areas 34.The center 30 is deep into enough depth in the head 24 to provide the appropriate engagement of screwdriver head insertion
Degree, and there is a slot bottom 36 (see Fig. 4).Several external zones 32 are angularly separatedly looped around around the center 30.?
In the present embodiment, which includes four external zones 32, and adjacent two external zones 32 separates about 90 degree, so that the groove 28 is substantially
Upper presentation is cross, and in the present embodiment shown in Fig. 5, which includes six external zones 32, and adjacent two external zones 32 divides
Every about 60 degree, so that blossom type is generally presented in the groove 28.In other examples, which may include outside more
Enclose area 32, such as eight or 12.
Each external zones 32 is by two side walls 38 separated and 40 boundaries of an arcwall being attached between two side walls, 38 outer end
Fixed, the top surface 26 on side wall 38 and arcwall 40 from the head 24 is lean-in tiltedly to extend to slot bottom 36, and the arcwall 40 is opposite should
Center 30 presents and outwardly protrudes.When the combination sword (being not shown on figure) of screwdriver head is inserted into the groove 28 to rotate the screw 20
When, the both ends 41 of the arcwall 40 of each external zones 32 will provide a torsion point.Each connection area 34 is connected to adjacent two external zones
Between the inner end of 32 adjacent two side wall 38, so that adjacent two external zones 32 is concatenated area 34 and separates.Each connection area 34 is by a phase
Center 30 is defined by the circular arc wall 42 outwardly protruded, the top surface 26 on the circular arc wall 42 from the head 24 is lean-in tiltedly to prolong
Slot bottom 36 is reached, and the two side ends of the circular arc wall 42 respectively constitute a circular arc with the inner end of the side wall 38 for the external zones 32 being connect
Handover 44, the opposite center 30 of each circular arc handover 44, which is presented, to be inwardly concaved.Accordingly, when the combination sword of screwdriver head is inserted into the groove 28
When interior, each area 34 and the circular arc handover 44 of two sides of linking will constitute a matching surface, so that can closely paste with groove 28 in conjunction with sword
It closes.
The groove 28 constituted according to the present invention may be provided on the screw with any shape head, thus, there is manufacture
Convenient advantage.As shown in figure 3, the center 30 of the groove 28 has biggish aperture relative to the groove 14 of Fig. 1, so that rising
The combination sword of subheader can be more easily inserted into the groove 28.Furthermore the opposite center 30 of several external zones 32 is outside
The fixed length (L1) of protrusion one, and the arcwall 40 and two side walls, 38 outer end be formed by circular arc join 41 can provide it is larger
The torsion point of range, thus, which can create bigger torsion.In addition, the opposite center 30 of several circular arc walls 42
The length (L2) for outwardly protruding about 1-3mm, when the combination sword of screwdriver head is inserted into the groove 28, which can
The matching surface for combining sword to fit closely is provided, so that the two does not have to mesh together by the suction auxiliary of magnet, in turn
The screw 20 stability in use can be increased and do not increase the cost in manufacture.
What Fig. 6 to Fig. 8 showed one embodiment of the invention rushes tool 46, and punching tool 46 can be used to form screw recess of the invention
28.Punching tool 46 includes a formed punch 50 of a main body 48 and the protrusion of front end face 49 from the main body 48, which can be to one
The head impact of screw goes out the groove 28 (see Fig. 9).The formed punch 50 include a central part 52, from the central part 52 radially
The several outer parts 54 extended and the several linking parts 56 being connected between several outer parts 54, the central part 52 have
One preset longitudinal length is to go out the center 30 from the top surface 26 on the head 24.Several outer parts 54 are angularly separatedly
It is looped around around the central part 52.In the present embodiment, which includes four outer parts 54, and adjacent two outer part 54 divides
Every about 90 degree so that the lateral section of the formed punch 50 generally present it is cross.In a feasible embodiment, the formed punch 50 packet
Six outer parts 54 are included, adjacent two outer part 54 separates about 60 degree, so that plum blossom is generally presented in the lateral section of the formed punch 50
Type.In other feasible embodiments, which may include more outer parts 54, such as eight or 12.
Each outer part 54 is by 60 institute of an arcuate blade between two side edges 58 that separate and the outer end for being attached at two side edge 58
It defines, side edge 58 and arcuate blade 60 are extended by the inward slant of front end face 49 of the main body 48, and the arcuate blade 60 is with respect to central part 52
In outwardly protruding.Each linking part 56 is connected between adjacent two side edge 58 of adjacent two outer part 54, so that adjacent two outer part
54 are separated by a linking part 56.Each linking part 56 is defined by an opposite central part 52 by the Circular Nose Cutting Edge 62 outwardly protruded, the circle
Arc sword 62 is sloped inwardly by the front end face 49 of the main body 48 to be extended, and the two side ends of the Circular Nose Cutting Edge 62 and the outer part 54 that is connect
Side edge 58 respectively constitute circular arc handover 64, the opposite central parts 52 of each circular arc handover 64 are in inwardly concaving.Accordingly, when the formed punch
When the head 24 of 50 pairs of screws 20 impacts the groove 28, the central part 52 and several outer parts 54 will form the groove 28
Center 30 and external zones 32, and connection area 34 and circular arcs that the linking part 56 and circular arc handover 64 will form the groove 28
Handover 44.
In the foregoing specification, the present invention be only specific embodiment is described, and feature under this invention can still have it is more
Kind variation or modification.Therefore institute of the present invention will be incorporated into for being familiar with the obvious replacement and modification that this those skilled in the art can make
Within the scope of the patents of opinion.
