Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 2, that show the concrete structure of the embodiment of this utility model, it includes one
The body that body punch forming connects, described body surface configuration has nickel coating, to strengthen its electric conductivity.
This body has the portion that arches upward raised up；At depression angle, this rounded structure in portion that arches upward, described in arch upward portion
Having convex arc section 1 and be connected to the bending edge 2 of convex arc section 1 periphery, described bending edge 2 includes from convex arc section 1 periphery the most oblique
Downwardly extend the first hypotenuse portion 21 of setting and from the most extended the second hypotenuse portion of the first hypotenuse portion 21 periphery
22.The periphery stamping-out in this portion that arches upward is formed with four arc notch 3, between the periphery correspondence adjacent arcs v notch v 3 in the portion of arching upward
Remaining with four foot positions 4 altogether, the outboard end of described foot position 4 remains with the bending edge not being punched；The upper surface of described convex arc section 1
Center is arranged with groove 5, and the lower surface in convex arc section 1 is disposed with four protuberances 7 around groove 1, and each protuberance 7 is right
